Limit repairs to the implicated existing symbols: `http2_frame_parser::{priority_rules,finish_frame}`, `http2_request_engine::{feed,eof}`, its `state::{peer_reset,fail,reset}`, request-head conversion, stream-flow handling or the existing HPACK decoder. Do not weaken verdicts to fit current behavior. RFC 9113 remains the oracle; its deprecated priority semantics and retained framing rules require separate checks. [RFC 9113](https://www.rfc-editor.org/rfc/rfc9113.html#section-6.3) + +3. **Make HTTP/2 and HPACK fuzzing reproducible gates.** + + Reuse `test/fuzz/hpack_fuzz.cpp::{hpack_fuzz_input,hpack_fuzz_sections}` and `test/unit/hpack_corpus_test.cpp`; they already exercise bounded primitives, two-block compression state and deterministic mutations. + + Add committed malformed HPACK seeds under `test/data/hpack/seeds/`, with the eight control bytes required by the existing fuzz input format. Include RFC example blocks and the malformed families above. Add a deterministic seed replay case to `hpack_corpus`. + + Add `test/fuzz/http2_engine_fuzz.{hpp,cpp}` and `test/unit/http2_fuzz_replay_test.cpp`. Drive the actual `http2_request_engine` with fixed small stream/body/output budgets, a serialized executor, bounded routes and a fixed clock. Cap input at 64 KiB, owner-pump iterations and generated response bytes. Check consumption bounds, stable terminal behavior, output advancement, accounting limits and complete release on destruction. Compare equivalent input fragmentations under the same deterministic pumping schedule; avoid assertions whose result legitimately depends on route scheduling. + + Extend `scripts/run-v3-protocol-fuzz.sh` with explicit target selection so TASK-145 can request `hpack http2_engine` without rerunning unrelated fuzzers. Preserve current defaults. Use `HPACK_LIBFUZZER` for the existing HPACK entry and its 512-byte limit. Copy seeds into writable build-local corpora, retain crash artifacts and reproduction commands, and fail on missing instrumentation. Extend `test/integ/protocol_fuzz_runner_test.py` for selected-target validation and unavailable-tool behavior. Register all new corpus assets in `EXTRA_DIST`. + +4. **Add one bounded TLS fixture and two independent client adapters.** + + Add `test/integ/http2_tls_fixture.cpp`, conditionally built under `NATIVE_V3_TLS`. Compose: + + ```text + loopback socket, port 0 + → existing tls_session, credentials registry, negotiated ALPN h2 + → existing http2_request_engine + → existing route_registry and manual_executor + ``` + Reuse credential loading patterns from `tls_credentials_fixture.hpp` and TLS composition patterns from `http2_tls_boundary_test.cpp`. Pump `tls_session::{feed,drain,handshake,read,write}` and engine `feed/output/advance_output` with bounded buffers, deadlines and partial-write handling. Serialize all engine/route operations. Bind only loopback; publish `READY ` after listen. Bound accepted connections, active streams, total test bytes and lifetime. On STOP, EOF, timeout or client failure, cancel operations, destroy the engine and close sockets. + + Fixture routes should be only `/` for h2spec GET/POST returning 200 with nonempty data, `/hold`, `/health`, `/upload-hold`, `/large` and `/ws`. Use stdin commands to release suspended routes/body reads and inspect bounded event counters; no readiness sleeps. Record enough passive DATA/window and handler-completion evidence to prove flow stalls and cancellation without adding production observability APIs. + + Add: + - `test/integ/http2_client_h2.py`: pinned hyper-h2 **4.4.1**, Python TLS with ALPN `h2`. + - `test/integ/http2_client_node.mjs`: Node **24.15.0**, `node:http2`, recording `process.versions.nghttp2`. + + These are separate HTTP/2/HPACK implementations. Both document Extended CONNECT support. Keep client dependency installation in a task-local environment and add a small pinned test requirements file; no production dependency changes.

Preserve the hyper-h2 4.4.1 pin. + + Each client must independently pass the same scenarios on one connection: + + - `/hold` remains suspended while `/health` completes; release then completes the held stream. + - Client CANCEL resets a suspended/uploading stream; cancellation occurs once and a sibling completes. + - Uploads exceed both stream and aggregate connection credit with fixture body consumption held. Observe bounded DATA/stall, then release reads and verify resumed transfer with exact byte counts. + - Small response stream window stalls `/large`; increasing credit resumes complete, exact delivery. + - Await server `SETTINGS_ENABLE_CONNECT_PROTOCOL=1`, send valid RFC 8441 headers without END_STREAM, exchange masked text/binary WebSocket messages and ping/pong, complete Close, and complete a sibling GET while the WebSocket is active. + + A small client-side WebSocket framing helper is acceptable; HTTP/2 and HPACK must come from each independent stack. HTTP/1 WebSocket receipts, raw transcripts and OpenSSL-only peers cannot substitute for either client. If a pinned client cannot perform a required scenario, report its exact capability/dependency blocker. + +5. **Add supplemental h2spec evidence with checked exclusions.** + + Add a TASK-145 runner, preferably `scripts/run-v3-http2-gates.py`, plus `test/integ/http2_gate_runner_test.py`. Give it explicit build, log, Python, Node, h2spec and compiler arguments. Required requests fail on absent dependencies, fixture startup/ALPN failure, timeout, subprocess failure, empty coverage or malformed result output. Preserve logs and subprocess statuses; always reap fixture processes. + + Pin h2spec **v2.6.0** and record binary/source identity. It targets RFC 7540/7541, so its results supplement the RFC 9113 corpus. [h2spec usage and versions](https://github.com/summerwind/h2spec) + + Run TLS mode with explicit host/port, bounded per-case timeout and machine-readable results. Capture the full `--dryrun` inventory first. Add `test/conformance/http2/h2spec-exclusions.tsv` containing exact discovered case IDs, legacy assertion, RFC 9113 section and rationale. Map exclusions from the pinned tool’s actual inventory/source; do not invent IDs. + + Only demonstrated obsolete assertions, such as deprecated priority semantics or h2c Upgrade requirements if present, qualify. Continue running retained PRIORITY framing tests. Do not exclude entire sections, compression errors, flow failures, malformed-header failures, timeouts or fixture bugs. Require every discovered case to be either executed or explicitly excluded; unexpected failures remain fatal. A genuinely empty exclusion list is valid if no incompatible assertions occur.

It is built on top of [libmicrohttpd](https://www.gnu.org/software/libmicrohttpd/) -and, like its substrate, it is a daemon library. The mission is to expose -every useful HTTP capability through a simple, modern C++ API so that -application code can focus on business logic rather than on the mechanics of -HTTP request handling. - -**Design.** libhttpserver is lambda-first. The shortest server is ten -lines and uses no inheritance; handlers are -`std::function`; responses are -value-typed with seven factories and fluent `with_*` chaining; ownership -of resource-form handlers is expressed in `std::unique_ptr` and -`std::shared_ptr`. The class form (`http_resource`) is the right shape -when several methods on one path share mutable state. - -**Two contracts are load-bearing** — and both are stated explicitly in this -README rather than left implicit: - -- **Thread-safety** (DR-008 / §5.1). Every public method on `webserver` is - thread-safe and re-entrant from inside a handler, with two - documented exceptions (`stop()`, `~webserver()`) that deadlock if invoked - from a handler thread. -- **Error propagation** (DR-009 / §5.2). A handler that throws is caught - by the dispatcher and routed through `internal_error_handler`. There is - no throw-as-status idiom — to send a 404 from a handler, build it by value - with `http_response::empty().with_status(404)`. - -libhttpserver decodes form bodies automatically: `application/x-www-form-urlencoded` -and `multipart/form-data` are parsed into the request's argument map. Files -attached to multipart uploads are exposed through `http_request::get_files()`. - -All functions are reentrant and thread-safe unless explicitly stated otherwise. -Clients can also specify resource limits on overall connection count, per-IP -connection count, and per-connection memory to avoid resource exhaustion. +libhttpserver handles HTTP transport and request lifecycles while your +application supplies routes and policy. The installed `` +umbrella includes the native API; you may also include individual headers under +[`src/httpserver/`](src/httpserver/). Non-template operations are compiled into +`libhttpserver`, so consumers must link the library. + +The API separates a request head from its body. A coroutine receives an +`exchange&` as soon as the complete head is routed. It can reject immediately, +admit and consume the body, suspend while application work completes, send a +response, or upgrade to a WebSocket. A bounded synchronous adapter collects a +small body and invokes a value-returning function. Both forms use the same +routing and protocol machinery. + +Ownership and capacity are explicit. A request belongs to its handler task; +response definitions are immutable and may be shared subject to their source's +replay contract; network queues and protocol state have bounded capacities. +Expected failures carry `http::outcome`, and a handler exception is contained at +the request boundary. Shutdown initiation is safe inside handlers; joining work +belongs to a controlling thread. + +This manual teaches ordinary use in that order. The +[native API guide](docs/v3-api.md), +[protocol capacity reference](docs/v3-protocol-limits.md), and +[native architecture](specs/architecture/v3/architecture.md) provide additional +detail. See [release notes](RELEASE_NOTES.md) for release information. [Back to TOC](#table-of-contents) ## Requirements -libhttpserver can be used without any dependencies aside from libmicrohttpd. - -The minimum versions required are: - -* g++ >= 11 or clang >= 13 (Apple Clang from Xcode 15+) -* C++20 or newer -* libmicrohttpd >= 1.0.0 -* *[Optionally]* for TLS (HTTPS) support, you'll need [libgnutls](http://www.gnutls.org/). -* *[Optionally]* to compile the code reference, you'll need [doxygen](http://www.doxygen.nl/). - -On **RHEL 9** (and derivatives), the stock GCC 11 is too old for some C++20 -library features the build relies on; install the `gcc-toolset-14` package -and `source /opt/rh/gcc-toolset-14/enable` before configuring. +The plaintext build requires a C++20 compiler and standard library, threads, +and the platform's socket facilities. Building a source checkout also requires +Autoconf, Automake, Libtool, Make and pkg-config. `./bootstrap` generates the +configure script and Makefile inputs. Doxygen is optional for generated API +documentation; libcurl is used by tests and is not a library dependency. -Additionally, for MinGW on Windows you will need: +TLS is optional and disabled by default. The TLS build requires genuine stable +**OpenSSL 3.5.9 or later within the 3.5 release line**, including the linkable +QUIC TLS callback API. Configure checks headers, library identity and the +required provider operations.

See the +[TLS build guide](docs/native-tls-build.md) for provider verification and +commands. A TLS-enabled binary still needs valid published credentials and a +TLS listener configuration before it can accept encrypted traffic. + +### Building on Windows with MSYS2 + +Use the MINGW64 shell and a MinGW-w64 C++20 toolchain for native Windows +applications. Install its compiler, Make, Libtool and pkg-config together with +the MSYS Autotools tools, then follow the out-of-tree plaintext build above. +Add the matching curl development package if running tests. Configure recognizes +MinGW and MSYS hosts; MSYS builds depend on `msys-2.0.dll`. MinGW applications +still need the runtime libraries required by their selected compiler. + +Libtool produces a static `.a` archive, a DLL and a `.dll.a` import library when +the respective build forms are enabled. DLL naming follows Libtool's host +convention. This Autotools workflow uses GCC-compatible toolchains. Use +pkg-config with `-std=c++20` for consumers: private metadata includes pthread +and Windows networking/crypto libraries (`ws2_32`, `mswsock`, `bcrypt`). TLS +requires a matching supported OpenSSL installation on this platform too. -#### Library files on Windows +[Back to TOC](#table-of-contents) -When building with GCC-based toolchains (MSYS2/MinGW, Cygwin), the -following library files are generated: +## Getting started: Hello, world -| File | Purpose | -|------|---------| -| `libhttpserver.a` | Static library archive | -| `libhttpserver.dll` | Shared library (DLL) | -| `libhttpserver.dll.a` | Import library for linking against the DLL | -| `libhttpserver.la` | Libtool archive (used by libtool during linking) | +The [opening program](#tldr) constructs `server_options`, adds a loopback TCP +listener and passes a copy of the options to `native_server`. Port 8080 is fixed; +use port 0 to let the OS choose an available port and inspect it through +`get_bound_port(0)` after listening. -**Note about `.lib` files:** the `.dll.a` format is the import library format -used by GCC toolchains. If you're looking for `.lib` files, those are the -MSVC (Microsoft Visual C++) import library format and are only generated -when building with the MSVC toolchain. The `.dll.a` file serves the same -purpose as `.lib` but for GCC-based compilers. +`route_sync(method, pattern, handler, body_cap)` registers a bounded handler. +It receives `const http::request_head&` and `std::span` and +returns `server::sync_response`: status, fields and owned body bytes. The body +cap must be at least 1. A body exceeding the declared cap produces 413 without +invoking the function; a bodyless request passes an empty span. The adapter +supplies `Content-Length` when the returned fields have no explicit framing. -**Linking against libhttpserver:** +Register all routes before `listen()`, check registration and startup outcomes, +and keep the server alive while requests are being handled. `listen()` starts +managed hosting and returns; it does not occupy the main thread. The example +waits on stdin and calls `stop()` from that controlling thread, which joins +engine tasks and workers before local state is destroyed. -Using pkg-config (recommended): +In another terminal: ```sh -g++ myapp.cpp $(pkg-config --cflags --libs libhttpserver) -o myapp +curl -v http://127.0.0.1:8080/hello ``` -Manual linking: - -```sh -g++ myapp.cpp -I/mingw64/include -L/mingw64/lib -lhttpserver -lmicrohttpd -o myapp -``` +The response is `Hello, World!`. A HEAD route must be registered explicitly if +you want HEAD requests to succeed; GET registration alone does not provide it. +The [routes example](examples/routes.cpp) demonstrates GET and HEAD together.

Walking -through it: - -* `webserver ws{create_webserver(8080)};` — `create_webserver` is a fluent - builder for the server configuration; `webserver` is constructed by - direct initialisation from the builder. `webserver` is non-copyable and - non-movable; pass it by reference once it exists. The constructor is - `explicit`, so callers must direct-init rather than rely on implicit - conversion. -* `ws.on_get("/hello", [](const http_request&) { ... });` — register a - GET-only handler. The handler is a - `std::function`. There is no - subclass, no `shared_ptr`, no raw pointer. The seven HTTP-verb - shortcuts are `on_get`, `on_post`, `on_put`, `on_delete`, `on_patch`, - `on_options`, and `on_head`. For CONNECT and TRACE, use the - `route(http_method::CONNECT, ...)` and `route(http_method::TRACE, ...)` - forms covered under [Routing](#routing). -* `return http_response::string("Hello, World!");` — `http_response` is - a value type. Factories on `http_response` build common shapes; the - fluent `with_*` mutators add headers, footers, cookies, and status. - The response is returned by value into the dispatcher. -* `ws.start(true);` — `true` means *block this thread until the server - is stopped*. Pass `false` to start the listener and return immediately; - later call `stop_and_wait()` from another thread. - -To test the example, you can run the following from a terminal: +## Callable handlers and shared state -```sh -curl -XGET -v http://localhost:8080/hello -``` +Choose the synchronous form for quick computation over a bounded complete +body.

The configured `log_error` - callback continues to receive the verbatim message regardless of - this flag — only the HTTP response body is affected. - **Warning:** exception messages routinely contain file paths, SQL - fragments, internal identifiers, and attacker-influenced input. - Enable only in development or behind an explicit `#ifndef NDEBUG` - guard. A configured `internal_error_handler` is unaffected — it - always receives the message and can build any body it wants. - -A worked example: +### Defaults and startup + +The default protocol set is HTTP/1.0 plus HTTP/1.1. The default loop mode is +`managed`; workers 0 lets the runtime select concurrency. At most 64 listeners +and 1024 explicit workers are accepted. Timeout fields must be positive and at +most 24 hours. Defaults are handshake 30 s, header 30 s, body idle 60 s, +suspension 300 s, write idle 30 s, WebSocket close 10 s and drain 30 s. + +`validate()` is pure semantic validation: no descriptors, environment reads, +credential loading or binding. `resolve_limits(out)` also checks build support +and computes startup policy. `listen()` checks credentials/backend readiness, +validates, binds configured listeners and starts hosting. Check its outcome: +startup can still fail because an address is unavailable or credentials are +missing. Failed partial binding is terminal for that server object; construct a +new object for another attempt. + +### Budgets and protocol capacities + +`budgets()` holds aggregate resource capacities: connections, streams, header +bytes/fields, body buffers, response queues, HPACK/QPACK tables, blocked headers, +QUIC reassembly, WebSocket messages, timers and routes. The resource budget model +charges a reservation against its scope and ancestors. Byte capacities count +storage in flight; count capacities limit live objects. Response queue charges +include retained storage and metadata, so they can exceed payload byte counts. + +Default server capacities include 1024 connections, 4096 streams, 1 MiB header +bytes, 256 header fields, 8 MiB body buffers, 4 MiB response queues and 1024 +routes. Use the [budget header](src/httpserver/server/budgets.hpp) for all defaults +and ceilings. A body admission cap bounds that request's buffering and is +separate from aggregate server capacity. + +The optional `http2()`, `http3()` and `quic()` profiles tune their respective +protocol state independently. They do not enable a protocol. For example, +after choosing an appropriate TLS TCP listener and enabling HTTP/2: ```cpp -auto cfg = httpserver::create_webserver(8080) - .not_found_handler([](const httpserver::http_request&) { - return httpserver::http_response::string("nope").with_status(404); - }) - .method_not_allowed_handler([](const httpserver::http_request&) { - return httpserver::http_response::empty().with_status(405); - }) - .internal_error_handler([](const httpserver::http_request&, std::string_view what) { - // CWE-209: 'what' may contain file paths, SQL fragments, or - // attacker-influenced input. Log it internally; do NOT echo - // it to the HTTP client. - (void)what; // e.g. logger->error(what); - return httpserver::http_response::string("Internal Server Error").with_status(500); - }); -httpserver::webserver ws{cfg}; +options.http2().emplace().max_concurrent_requests = 192; +options.http2()->decoder_table_bytes = 8192; +options.http2()->encoder_table_bytes = 16384; +srv::effective_protocol_limits limits; +const auto resolved = options.resolve_limits(limits); +if (!resolved.ok()) { + std::cerr << resolved.message() << '\n'; + return 1; +} ``` -### File-upload options - -* **`.file_upload_target(file_upload_target_T t)`** — - `FILE_UPLOAD_MEMORY_ONLY` (default) keeps uploads in memory; - `FILE_UPLOAD_DISK_ONLY` writes to disk; `FILE_UPLOAD_MEMORY_AND_DISK` - does both. -* **`.file_upload_dir(const std::string& dir)`** — directory for - on-disk uploads. Must not be empty. -* **`.generate_random_filename_on_upload(bool = true)`** — name uploaded - files randomly (vs. trust the client's `Content-Disposition: filename=`). -* **`.file_cleanup_callback(file_cleanup_callback_ptr cb)`** — invoked - after request completion to clean up uploaded files. Return `true` to - delete the file from disk, `false` to keep it. - -### Daemon / external event-loop options - -These dovetail with the runtime methods covered under [Daemon -introspection and external event loops](#daemon-introspection-and-external-event-loops). -The `default_policy` selects which list is the exception list — i.e. what -happens to an address on neither list: - -* **`.default_policy(http::http_utils::policy_T p)`** — `ACCEPT` (default) - admits every address except those on the deny list (`deny_ip`); `REJECT` - refuses every address except those on the allow list (`allow_ip`). Under - either policy an allow entry overrides a matching deny entry. - -### Runtime operations on `webserver` - -Once constructed, the `webserver` instance exposes: - -* **`bool start(bool blocking = false)`** — start listening. When - `blocking == true`, this thread blocks until the server stops. -* **`bool stop()`** — stop the daemon and join libmicrohttpd's worker - threads. **Calling this from inside a handler deadlocks** — see - [Threading contract](#threading-contract). -* **`void stop_and_wait()`** — `stop()` then wait until every in-flight - handler has returned. Same deadlock contract as `stop()`. -* **`bool is_running()`** — true if the daemon is currently accepting - connections. - -Registration verbs (covered in detail under [Routing](#routing)): -`on_get`, `on_post`, `on_put`, `on_delete`, `on_patch`, `on_options`, -`on_head`, `route(...)`, `register_path(...)`, `register_prefix(...)`, -`register_ws_resource(...)`, and the matching `unregister_*` forms. +Profiles must fit aggregate budgets and protocol bounds. See the +[capacity tables](docs/v3-protocol-limits.md) and +[protocol options example](examples/protocol_options.cpp) for complete HTTP/2, +HTTP/3 and QUIC configurations. `native_server::effective_limits(out)` exposes +the immutable resolved local policy before listening and after stopping. It is +startup policy, not negotiated peer SETTINGS, live queue occupancy or a way to +resize a running engine. Failure leaves `out` unchanged. [Back to TOC](#table-of-contents) -## The resource object - -The `http_resource` class represents a logical collection of HTTP methods -that will be associated with a URL when registered on the webserver. The -class is **designed for extension**. When the webserver matches a request -against a resource, the method corresponding to the request's HTTP verb -is called on the resource. +## Resource ownership -The `http_resource` class contains the following extensible methods -(also called *handlers* or *render methods*) — every one returns -`http_response` by value: +Routes own their callables; captured smart pointers express shared application +ownership. The server retains listener credential stores and copies options. +References returned by `hooks()` and `peer_policy()` are valid for the server's +lifetime. The `readiness()` adapter is borrowed and server-owned. -* **`http_response render_get(const http_request& req)`** — invoked on an HTTP GET request. -* **`http_response render_post(const http_request& req)`** — invoked on an HTTP POST request. -* **`http_response render_put(const http_request& req)`** — invoked on an HTTP PUT request. -* **`http_response render_head(const http_request& req)`** — invoked on an HTTP HEAD request. -* **`http_response render_delete(const http_request& req)`** — invoked on an HTTP DELETE request. -* **`http_response render_trace(const http_request& req)`** — invoked on an HTTP TRACE request. -* **`http_response render_options(const http_request& req)`** — invoked on an HTTP OPTIONS request. -* **`http_response render_connect(const http_request& req)`** — invoked on an HTTP CONNECT request. -* **`http_response render_patch(const http_request& req)`** — invoked on an HTTP PATCH request. -* **`http_response render(const http_request& req)`** — fallback invoked when no method-specific override is provided. +An `exchange` and its request head belong to the active request task. Read its +fields and captures there; copy strings or values that must survive the request. +Body read results view your destination buffer. Keep buffers alive across their +awaited operations and avoid moving an exchange while a read/write is pending. -These methods are all `virtual`; override only the verbs your resource -supports. Unhandled verbs fall through to `render()`; if the resource also -does not override `render()`, the dispatch returns the configured 405 -response. - -### Restricting allowed methods - -By default, every HTTP verb falls through to `render()`. To narrow a -resource to a specific subset of methods, use the `set_allowing` / -`disallow_all` API: - -```cpp -class read_only : public httpserver::http_resource { - public: - read_only() { - disallow_all(); - set_allowing("GET", true); - set_allowing("HEAD", true); - } - httpserver::http_response render_get(const httpserver::http_request&) override { - return httpserver::http_response::string("ok"); - } -}; -``` - -Requests for disallowed verbs are short-circuited by the dispatcher and -land in the `method_not_allowed_handler` (HTTP 405) without calling -`render_*`. See [`examples/allowing_disallowing_methods.cpp`](examples/allowing_disallowing_methods.cpp) -for a worked example. - -### Ownership - -Resources are passed to the webserver via `std::unique_ptr` (the -webserver takes exclusive ownership) or `std::shared_ptr` (caller and -webserver share ownership). Ownership is always expressed through a -smart pointer. +`response_definition` shares immutable state. A definition must outlive every +`send_definition()` task using it; capturing the definition by value in a route +is a convenient way to ensure this. Its source determines replay and storage +ownership, described under [Response](#response). Handles such as a +`drain_ticket` or an accepted WebSocket session own their associated state, but +they do not make unrelated application captures live longer. [Back to TOC](#table-of-contents) ## Routing -The `webserver` exposes three families of registration entry points. -They are all interoperable: within one server, some paths can be -lambdas and others can be `http_resource` subclasses. - -### Lambda form: per-method, exact path - -`on_get`, `on_post`, `on_put`, `on_delete`, `on_patch`, `on_options`, -`on_head` — each takes an exact path and a -`std::function`: - -```cpp -ws.on_get("/hello", [](const http_request&) { - return http_response::string("Hello, World!"); -}); -ws.on_post("/items", [](const http_request& req) { - return http_response::string("created: " + std::string{req.get_arg("name")}) - .with_status(201); -}); -``` - -Re-registering the same `(method, path)` pair throws. The seven -shortcuts cover the seven verbs with first-class handler functions; -CONNECT and TRACE go through `route()` (below). - -### Lambda form: atomic multi-method via `route()` - -`route()` is the primary escape hatch when the HTTP method is known -only at runtime (e.g. loaded from config, selected from a dispatch -table). The single-method form: - -```cpp -route(http_method m, "/info", handler) -``` - -takes a runtime `http_method` value and is the canonical form for -config-driven or table-driven registration (PRD-HDL-REQ-006). - -`route(method_set methods, "/info", handler)` additionally allows -registering a handler under several methods in a single critical -section — either every slot is registered, or none of them are: - -```cpp -ws.route(http_method::GET | http_method::HEAD, "/info", - [](const http_request&) { - return http_response::string("info"); - }); -``` - -A `method_set` is the bitwise-or of `http_method` values. This is the -only entry point through which CONNECT and TRACE are reachable as -lambdas: `route(http_method::CONNECT, "/proxy", handler)`. - -### Resource form: `register_path` and `register_prefix` - -For `http_resource` subclasses (the [class form](#class-form-handlers)): - -```cpp -ws.register_path("/count", std::make_unique()); // exact match -ws.register_prefix("/static", std::make_unique()); // subtree match -``` - -Both methods have `std::shared_ptr` overloads for the -case where you need to retain a reference to the resource: - -```cpp -auto cnt = std::make_shared(); -ws.register_path("/count", cnt); -// cnt is still usable from outside the webserver. -``` - -**Parameterised paths.** Brace syntax captures path segments: +All enabled HTTP versions use the same route table. Register before `listen()`; +registration closes once `listen()` runs and later attempts return +`invalid_state`. Registration returns typed failures for malformed patterns, +invalid/empty methods or handlers, duplicate overlapping registrations and +route-budget exhaustion. -```cpp -ws.register_path("/users/{id}", std::make_unique()); -``` +`route(method, pattern, handler)` accepts one known or extension method. +`route(method_set, pattern, handler)` accepts multiple known methods. +`route_prefix(method_set, pattern, handler)` matches a subtree. A method set is +built with `set(http::method_id::get)` and similar calls; an extension method is +created with `http::method::extension("CUSTOM")` and registered individually. +`route_sync` registers one bounded synchronous method at a time. -The captured value is available inside the handler via -`http_request::get_arg("id")`. +Patterns are slash-separated literal segments or whole `{name}` segments. +Parameter names contain letters, digits or underscores and must be unique +within a pattern. Captures are separate from query/form fields and available +in registration-pattern order through `exchange::path_args()`. -**Per-segment regex constraints.** Add a regex after a pipe to constrain -a segment: +This helper registers a parameterized coroutine route and returns the +registration outcome (include ``): ```cpp -ws.register_path("/users/{id|[0-9]+}", std::make_unique()); +http::outcome add_item_route(srv::native_server& server) { + return server.route(http::method::known(http::method_id::get), "/items/{id}", + [](httpserver::exchange& x) -> httpserver::task { + const std::string text = x.path_args().front().value; + http::fields fields; + fields.append("Content-Length", std::to_string(text.size())); + if (!x.start_response(http::status::from_code(200), fields).ok()) co_return; + const auto written = + co_await x.writer().write(std::as_bytes(std::span(text))); + if (!written.status.ok()) co_return; + if (!(co_await x.writer().finish()).status.ok()) co_return; + }); +} ``` -Only requests where the `id` segment matches `[0-9]+` will match this -registration. - -Regex validation is on by default; disable with `regex_checking(false)` -on the builder if you need pure literal-path semantics. +### Precedence and methods -**Unregistration.** `unregister_path(path)` and `unregister_prefix(path)` -remove an exact-match or prefix-match registration respectively. -`unregister_resource(path)` is a kind-agnostic convenience that atomically -clears whichever kind (exact or prefix) is registered at `path` — use it -when the caller does not track how the resource was registered. +Full matches are considered before prefixes. Within full matches, the first +registration accepting the method wins; literals and parameter patterns share +that registration-order tier. Register `/items/special` before `/items/{id}` if +the literal should win. Among prefix matches, the deepest accepting pattern +wins, with registration order breaking ties. `/` is a catch-all prefix. -## Request +The tier decision is method-blind: a full-match path with the wrong method owns +the 405 instead of falling through to a prefix. The selected tier's methods +supply `Allow`. A complete path miss produces 404. GET does not imply HEAD; +register HEAD explicitly.

[Back to TOC](#table-of-contents) -## Response - -`http_response` is a **value type** — move-only, returned by value, -never `shared_ptr`-wrapped. There is no class hierarchy of body -subclasses; the body shape is a runtime detail of one type. Build a -response with one of the seven factories described below and decorate -it with the fluent `with_*` mutators. - -### The seven factories - -| Factory | Body shape | Use when | -|---|---|---| -| `http_response::string(body, [status, content_type])` | In-memory string (small bodies live inline via SBO) | The body is already in memory | -| `http_response::file(path)` | Stream a file from disk | The body is a static or generated file on disk | -| `http_response::iovec(entries)` | Scatter-gather over a vector of `iovec_entry` (zero-copy) | The body is assembled from several existing buffers | -| `http_response::pipe(fd)` | Stream from a pipe / FIFO | The body is being produced by another process or thread | -| `http_response::empty([status])` | Empty body | 204 No Content, redirects, HEAD responses | -| `http_response::deferred(producer, [closure, content_type])` | Body produced incrementally by a callback | The body cannot be materialised up-front (long-poll, streaming) | -| `http_response::unauthorized(realm, [status, content_type, algorithm])` | 401 with the proper `WWW-Authenticate` header | Reject a request that lacks valid credentials | - -`iovec_entry` is the element type of the `iovec()` vector: - -```cpp -struct iovec_entry { - const void* base; // borrowed for the response's lifetime - size_t length; -}; -``` - -The `base` pointer is **borrowed**: the caller must keep the underlying -storage alive until the response has been fully written to the wire. -For owning scatter-gather, copy your strings into a `std::vector` -that the response captures by value. - -### Fluent mutation - -Every `http_response` exposes `with_status`, `with_header`, `with_footer`, -and `with_cookie`. These return `*this` (by reference on lvalues, by -rvalue-reference on rvalues), so calls can chain: - -```cpp -return httpserver::http_response::string("hi") - .with_header("X-Trace-Id", trace_id) - .with_status(201); -``` - -The fluent helpers are intentionally narrow — every other mutation -(content type, body data) is set at the factory call. This keeps the -"build it, return it, done" idiom uniform across response shapes. - -### Building error responses by value +## Request -There is **no throw-as-status idiom**. To return a 404 from a handler, -build it explicitly: +### Head and peer data + +`x.head()` returns the complete semantic head: + +| Member/accessor | Meaning | +| --- | --- | +| `raw_target` | Exact received target bytes, preserving escapes and query | +| `route_path` | Validated/normalized input used by routing | +| `request_method` | `http::method`, including extension identity | +| `request_protocol` | `http::protocol` for this request | +| `head_fields` | Ordered header fields, including repetitions | +| `x.path_args()` | Named path captures; separate from query and form data | +| `x.peer()` | Immutable transport address/port snapshot | +| `x.connection_id()` | Library connection identity for correlation | +| `x.tls()` | Shared immutable TLS peer metadata; absent for plaintext | + +`http::fields::first(name)` returns an optional first value; +`all(name)` returns all matching values with case-insensitive field names. +`entries()` preserves order. Use `append` to retain repeated values and +`replace` when replacing all values for one name. + +Query decoding is explicit. Extract the suffix after `?` from `raw_target` and +pass its bytes to `forms::decode_urlencoded(encoded, limits, out)`. A +`form_fields` collection preserves repeated pairs and empty values. Cookie +parsing is also explicit: include `` and call +`http::parse_cookie_header()` on each Cookie field. Do not flatten repeated +headers or cookies unless that is the policy you want. The +[request data example](examples/request_data.cpp) demonstrates these operations. + +### Body admission and incremental reads + +A handler can answer directly from the head to refuse an upload before admitting +its body. `admit_body(body_policy{cap})` starts bounded body delivery and allows +`x.body()` operations. A zero policy cap selects the engine default; choose an +explicit positive bound for predictable request handling.

Use only - for non-sensitive content or under HTTPS. With Basic auth, the - application sees the cleartext password — useful for chained - authentication against an external store. Enable / disable with - `basic_auth(true|false)` on the builder. -* **Digest authentication** — a one-way authentication scheme based on - hash algorithms (MD5, SHA-256, or SHA-512/256). Only the hash transits - the network; a server-issued nonce prevents replay attacks. Appropriate - for general use, especially when HTTPS is not available. SHA-256 is the - default; SHA-512/256 is also supported for stronger security. Enable / - disable with `digest_auth(true|false)`. -* **Client-certificate authentication (mTLS)** — uses an X.509 - certificate from the client. The strongest of the three mechanisms, - but requires HTTPS. Combines well with Basic or Digest for layered - authentication. Enable with `use_ssl(true)` plus configured `https_mem_trust`. -* **Centralized authentication** — a single per-request callback that - runs *before* any resource's render method, so individual handlers - don't need to repeat auth code. Configured via `auth_handler` and - `auth_skip_paths` on the builder. - -### Using Basic authentication +This handler sends generated chunks without buffering the whole response: ```cpp -class user_pass_resource : public httpserver::http_resource { - public: - httpserver::http_response render_get(const httpserver::http_request& req) override { - if (req.get_user() != "myuser" || req.get_pass() != "mypass") { - return httpserver::http_response::unauthorized("test@example.com"); - } - return httpserver::http_response::string( - std::string{req.get_user()} + " " + std::string{req.get_pass()}); +httpserver::task download(httpserver::exchange& x) { + http::fields fields; + fields.append("Content-Type", "text/plain"); + if (!x.start_response(http::status::from_code(200), fields).ok()) co_return; + const std::string chunk = "generated-chunk\n"; + for (int i = 0; i < 64; ++i) { + const auto written = co_await x.writer().write(std::as_bytes(std::span(chunk))); + if (!written.status.ok()) co_return; } -}; - -int main() { - httpserver::webserver ws{httpserver::create_webserver(8080)}; - ws.register_path("/hello", std::make_unique()); - ws.start(true); + http::fields trailers; + trailers.append("X-End", "complete"); + if (!(co_await x.writer().finish(trailers)).status.ok()) co_return; } ``` -To test: +The engine chooses framing for an unframed streaming response according to the +protocol. If you declare `Content-Length`, supply exactly that body length. +Trailer support and body-forbidden statuses follow protocol rules; do not add +conflicting framing fields. Once the head is accepted, a later failure must +abort/reset/close according to the protocol rather than replace the response. -```sh -curl -XGET -v -u myuser:mypass http://localhost:8080/hello -``` +### Immutable response definitions -You will get back the user and password you passed.

Default implementation does nothing. -* **`void on_ping(websocket_session& session, std::string_view payload)`** — called when a ping frame is received. Default implementation sends a pong. -* **`void on_close(websocket_session& session, uint16_t code, const std::string& reason)`** — called when the WebSocket connection is closed. Default implementation does nothing. - -### The `websocket_session` class - -The `websocket_session` class provides methods to interact with the -client: - -* **`void send_text(const std::string& msg)`** — send a text message. -* **`void send_binary(const void* data, size_t len)`** — send a binary message. -* **`void send_ping(const std::string& payload = "")`** — send a ping frame. -* **`void send_pong(const std::string& payload = "")`** — send a pong frame. -* **`void close(uint16_t code = 1000, const std::string& reason = "")`** — close the WebSocket connection. -* **`bool is_valid()`** — true while the session is still open. - -### Registering WebSocket resources - -WebSocket handlers are registered with `register_ws_resource`, which -takes ownership of a `websocket_handler` subclass via `std::unique_ptr` -(or shares it via `std::shared_ptr`): - -```cpp -class echo : public httpserver::websocket_handler { - public: - void on_message(httpserver::websocket_session& session, - std::string_view msg) override { - session.send_text("Echo: " + std::string{msg}); - } -}; - -int main() { - httpserver::webserver ws{httpserver::create_webserver(8080)}; - ws.register_ws_resource("/echo", std::make_unique()); - // or, with shared ownership: - auto handler = std::make_shared(); - ws.register_ws_resource("/echo2", handler); - ws.start(true); -} -``` - -On a build with `HAVE_WEBSOCKET` disabled — for example, when the system -libmicrohttpd was built without WebSocket support — `register_ws_resource` -throws `feature_unavailable`. See [Feature -availability](#feature-availability) for how to detect this at runtime -without preprocessor gates, and -[`examples/websocket_echo.cpp`](examples/websocket_echo.cpp) for a -worked example. +Register a coroutine route and call `co_await x.upgrade(options)` before a +terminal response/body delivery. The same surface supports HTTP/1.1 Upgrade, +HTTP/2 Extended CONNECT and HTTP/3 Extended CONNECT on their configured +transports. TLS-off listeners serve HTTP/1.1 upgrades; H2/H3 require their TLS +listeners. + +`ws_upgrade_options` specifies subprotocol preference, exact serialized origin +allowlists, absent-origin policy and session limits. By default an empty origin +allowlist accepts any syntactically valid origin and absent origins are allowed; +set explicit policy for browser-facing applications. Upgrade success means +bounded handshake admission (101 or a successful CONNECT response), not peer +acknowledgment. A refusal carries `rejection_status`/`rejection_fields` and leaves +the exchange open so the handler can send an ordinary HTTP response. + +The accepted result owns a `websocket::session`: + +- `receive()` yields owning message data or typed closure/failure. One receive + may be outstanding at a time. +- `try_send(kind, bytes)` copies the whole payload when accepted. Temporary + backpressure leaves queues unchanged and carries an OK status; inspect the + disposition as well as the status. +- `writable()` waits for capacity for at least an empty frame. Retry `try_send` + afterward; it does not promise room for an arbitrary message or acknowledge + delivery. Only one writable wait may be outstanding. +- `close(code, reason)` begins a bounded close handshake. Register `on_close` + once before terminal closure and retain the handle through notification. + +Session entry points synchronize shared state, but moving/destroying a handle +must not race access to that handle. Server drain initiates Close 1001 and bounds +the handshake by its remaining deadline. Use [websocket_echo.cpp](examples/websocket_echo.cpp) +and its [session helper](examples/example_ws.hpp) for a complete receive/send/ +backpressure loop and close lifetime management.

Especially useful when you pass port `0` to let the OS - choose an ephemeral port. -* **`int webserver::get_listen_fd()`** — the listen socket file - descriptor, or `-1` if not available. -* **`unsigned int webserver::get_active_connections()`** — the number of - currently active connections. -* **`bool webserver::is_running()`** — true if the daemon is currently - accepting connections. - -### External event-loop integration - -When using the server without internal threading (e.g. with -`listen_socket(false)` or with `start_method(EXTERNAL_SELECT)`), you can -drive the event loop yourself: - -* **`bool webserver::run()`** — process pending events once and return - immediately. -* **`bool webserver::run_wait(int32_t millisec)`** — block until events - are available or the timeout expires. -* **`bool webserver::get_fdset(void* read, void* write, void* except, int* max_fd)`** - — retrieve file descriptor sets for use with `select(2)`. -* **`bool webserver::get_timeout(uint64_t* timeout)`** — the maximum - time to wait before calling `run()` again. -* **`bool webserver::add_connection(int socket, const sockaddr* addr, socklen_t len)`** - — hand off an externally-accepted connection to the daemon. Used with - socket-activation or load-balancer integrations. -* **`int webserver::quiesce()`** — stop accepting new connections while - allowing in-flight requests to complete. Returns the listen socket FD, - which the caller can then close or pass elsewhere. - -### Stopping the daemon - -* **`bool webserver::stop()`** — stop the daemon, join libmicrohttpd's - worker threads, and return. **Calling `stop()` from inside a handler - deadlocks** (it joins the calling thread); see [Threading - contract](#threading-contract). -* **`void webserver::stop_and_wait()`** — equivalent to `stop()` plus a - drain that waits for every in-flight handler to return. Same deadlock - contract as `stop()`. - -A small example combining everything: - -```cpp -// Bind to an OS-chosen port, print the actual one, drive the loop -// externally, then drain on shutdown. -webserver ws{create_webserver(0).start_method(http::http_utils::EXTERNAL_SELECT)}; -ws.start(false); -std::cout << "listening on port " << ws.get_bound_port() << '\n'; -while (running) { - ws.run_wait(1000); -} -ws.quiesce(); -ws.stop_and_wait(); -``` - -See [`examples/daemon_info.cpp`](examples/daemon_info.cpp) and -[`examples/external_event_loop.cpp`](examples/external_event_loop.cpp) -for runnable demonstrations. +## Server introspection and external event loops + +`get_bound_port(listener_index)` reports the actual bound port, including an +OS-chosen ephemeral port. It returns 0 before listening or for an invalid index. +`is_running()` remains true during graceful rundown until stop initiation. +`effective_limits(out)` exposes resolved startup policy, and the diagnostic +channel supplies approximate live counters. + +Set `options.loop() = srv::loop_mode::external` before construction to let an +application event loop own readiness and timer advancement. Workers remain +library-owned. `server.readiness()` returns a stable borrowed adapter in external +mode and `nullptr` in managed mode; before listen/after stop it is inactive. + +The host loop follows this sequence: + +1. Obtain `driver->interests()`: a coherent owned snapshot of socket interests, + an optional wake interest and an optional next deadline. +2. Register the complete snapshot in the host loop. Omitted interests must be + unregistered. Handles are borrowed; only the library closes them. Preserve + the full-width Winsock carrier on Windows. +3. Wait for readiness or the deadline. Forward readiness with the original + `(socket_key, generation)`, including wake events; dispatch an empty event + batch when the deadline expires without socket readiness. +4. Call `driver->dispatch(events, steady_clock::now())`, check its outcome and + replace registrations from a fresh snapshot. Dispatch never waits; overlapping + or recursive calls on the same driver return `invalid_state`. Stale generation + callbacks are ignored. +5. Remove host registrations and discard borrowed handles before destroying the + server. A snapshot copy does not extend handle lifetime. + +The complete [external loop example](examples/external_event_loop.cpp) uses +[host_poll.hpp](examples/host_poll.hpp) for POSIX poll and Windows WSAPoll, +including wake handles and deadline-derived waits. The +[external loop contract](docs/external-loop-contract.md) specifies lifecycle and +threading details for other host loops.

The full list of named constants (status codes, common -methods, common content types, named algorithms) lives in -[`src/httpserver/http_utils.hpp`](src/httpserver/http_utils.hpp) — it -would be redundant to enumerate it here. +## HTTP utilities -The following utility functions are available on `http::http_utils`: +Use the semantic value headers rather than transport-specific constants: -* **`const char* reason_phrase(unsigned int status_code)`** — the - standard HTTP reason phrase for a given status code (e.g. `"OK"` for - 200, `"Not Found"` for 404). -* **`bool is_feature_supported(int feature)`** — whether a specific - libmicrohttpd feature is supported on the current system. Feature - constants are defined by the `MHD_FEATURE` enum. -* **`const char* get_mhd_version()`** — the version string of the - underlying libmicrohttpd library. +- `http::method::known(method_id)` constructs a standard method; + `method::extension(token)` preserves a valid extension token. `method_set` + represents standard methods for multi-method registration. +- `http::status::from_code(code)` constructs a status and `valid()` checks it. + Category predicates such as `success()` and `client_error()` classify it. +- `http::fields` preserves order/repetition, with `append`, `replace`, `first`, + `all`, `count` and `entries` for access. +- `` provides `cookie`, `parse_cookie_header` and + checked `render_set_cookie(cookie, out)`.

See [Feature + availability](#feature-availability) for how it relates to actual listeners. [Back to TOC](#table-of-contents) ## Lifecycle hooks -The hook bus is the single extension surface for observing or -short-circuiting the request lifecycle. It replaces v1's single-slot -patchwork (one `log_access` callback, one `not_found_handler`, one -`method_not_allowed_handler`, one `internal_error_handler`, one -`auth_handler`) with eleven distinct phases spanning connection, -request, routing, handler, and response. Each phase accepts multiple -subscribers and is observable both server-wide (via `webserver::add_hook`) -and, for the five post-route-resolution phases, per-route (via -`http_resource::add_hook`). The contract is captured in DR-012 and -[`specs/architecture/04-components/hooks.md`](specs/architecture/04-components/hooks.md). - -Each call returns a move-only `hook_handle`. The handle's destructor -removes the registration; `hook_handle::detach()` disarms the destructor -so the registration persists for the webserver's lifetime. - -### Phases - -| Phase | Fires at | Short-circuit | Per-route eligible | -|-------|----------|---------------|--------------------| -| `connection_opened` | New TCP / TLS connection accepted by MHD | No | No | -| `accept_decision` | After the default-policy / deny-list / allow-list verdict; the connection has been accepted or denied | No | No | -| `request_received` | Request line and headers parsed, body not yet consumed | Yes (`hook_action`) | No | -| `body_chunk` | Each upload-body chunk delivered by MHD | Yes (`hook_action`) | No | -| `route_resolved` | After URL → resource resolution; carries the matched route or "no match" | No | No | -| `before_handler` | After route resolution and method check, immediately before the handler runs | Yes (`hook_action`) | Yes | -| `handler_exception` | Exception escapes the handler, before `internal_error_handler` is consulted | Yes (`hook_action`) | Yes | -| `after_handler` | Handler returned a response, before it is queued on the wire (mutation point) | Yes (`hook_action`) | Yes | -| `response_sent` | Response handed to `MHD_queue_response`; carries `status`, `bytes_queued`, `elapsed` | No | Yes | -| `request_completed` | Request lifecycle finished (success or failure); last hook to fire per request | No | Yes | -| `connection_closed` | Connection torn down (peer close or server close) | No | No | - -### Short-circuit semantics - -Phases marked "Short-circuit" return a `hook_action`: -`hook_action::pass()` lets the chain continue; -`hook_action::respond_with(response)` aborts the chain at that -position. The wrapped response is sent on the wire in place of any -handler output. Subsequent hooks in the same phase are not invoked. -Observation-only phases (`connection_opened`, `accept_decision`, -`connection_closed`, `route_resolved`, `response_sent`, -`request_completed`) ignore the return; the chain always runs to -completion. - -### Per-route hooks - -`http_resource::add_hook(phase, fn)` accepts only the five -post-route-resolution phases: `before_handler`, `handler_exception`, -`after_handler`, `response_sent`, `request_completed`. Per-route hooks -fire after the server-wide chain at the same phase, and only if that -server-wide chain did not short-circuit. Passing any other phase -throws `std::invalid_argument` naming the rejected phase. See -[`examples/per_route_auth.cpp`](examples/per_route_auth.cpp) for a -worked example. - -### Examples - -* [`examples/denied_ip_log.cpp`](examples/denied_ip_log.cpp) — log every - denied-IP rejection via a single `accept_decision` hook. -* [`examples/early_413.cpp`](examples/early_413.cpp) — return 413 from - a `request_received` hook before the body is consumed. -* [`examples/clf_access_log.cpp`](examples/clf_access_log.cpp) — write - a Common Log Format access line from a `response_sent` hook. -* [`examples/per_route_auth.cpp`](examples/per_route_auth.cpp) — - per-route HTTP Basic auth via `http_resource::add_hook(before_handler, ...)`. - -### v1 aliases - -Each of the v1 single-slot setters is an alias for an `add_hook` call -at the corresponding phase. The aliases survive for ergonomic call -sites; new code can use either form. - -| v1 setter | Equivalent `add_hook` call | -|-----------|----------------------------| -| `log_access(fn)` | `ws.add_hook(hook_phase::response_sent, fn)` | -| `not_found_handler(fn)` | `ws.add_hook(hook_phase::route_resolved, fn)` | -| `method_not_allowed_handler(fn)` | `ws.add_hook(hook_phase::before_handler, fn)` | -| `internal_error_handler(fn)` | `ws.add_hook(hook_phase::handler_exception, fn)` | -| `auth_handler(fn)` | `ws.add_hook(hook_phase::before_handler, fn)` | - -The aliases install observation-stub hooks under the same dispatch -plumbing, so the on-the-wire behaviour is identical regardless of -which form the caller used. +Use `server.hooks().add(callback)` for server-wide request +policy/observation. Each callback receives its phase-specific context and +returns `hook_action`. The returned move-only `hook_handle` removes the +registration on destruction; keep it alive or call `detach()` for server-lifetime +registration. Add/remove operations are safe before and after listening. + +There are eight phases: + +| Phase | When | Capability | +| --- | --- | --- | +| `accept_decision` | Peer-policy verdict fixed | Observe verdict | +| `request_received` | Head before routing/body | Short-circuit | +| `route_resolved` | Lookup finished, including miss | Observe route | +| `before_handler` | Before call; also method mismatch | Short-circuit | +| `handler_exception` | Handler/eligible hook failure | Recovery response | +| `after_handler` | Head commitment | Mutate status/fields | +| `response_sent` | Engine accepted the committed head | Observe acceptance | +| `request_completed` | Exchange settles once | Observe typed result | + +`hook_action::pass()` continues the chain. The first `respond_with(hook_response)` +in a short-circuit-capable phase stops the remaining callbacks in that phase. +Observation phases ignore response actions; `after_handler` offers head +mutation rather than whole-body replacement. Registration order is preserved, +and changes during firing affect subsequent snapshots. + +For example, before listening, keep this handle in the controlling scope: + +```cpp +auto head_hook = server.hooks().add( + [](srv::after_handler_ctx& context) { + context.fields.append("X-Service", "example"); + return srv::hook_action::pass(); + }); +``` + +`response_sent` means head acceptance by the engine, not wire delivery of the +head or body. If the engine rejects framing/field bytes, that phase does not +fire and `request_completed` reports failure. Observe per-body progress in the +handler's read/write loop. Use wrapping route handlers for route-specific +policy, including authentication. + +Hook exceptions are contained and treated as pass. Unanswered precommit failures +from `request_received`, `route_resolved` or `before_handler` can be surfaced to +`handler_exception`; that chain is consulted at most once per request. Throws +from commit/completion phases cannot replace an accepted head. Keep callbacks +short, thread-safe and nonblocking; `accept_decision` runs on the accept task. +See the [hook contract](src/httpserver/server/hooks.hpp) and +[operations example](examples/operations.cpp). + +### Bounded diagnostics + +`server::diagnostics` is a copyable shared channel configured through +`options.diagnostic_channel()`. Default construction disables it. Records contain +scalar protocol/resource/lifecycle information rather than request/TLS identity. +Producers enqueue into a bounded 128-record queue; counters track drops and +callback failures. + +Call `channel.dispatch(max_events)` from your chosen control thread to deliver +a bounded batch outside engine/queue locks. New events cannot extend that call +beyond the queue observed at entry. Concurrent/recursive dispatch returns +`invalid_state`, and callback exceptions are counted/contained. Keep callback +captures alive through the last dispatch; destruction never dispatches. +`counters()` exposes event totals, active connections/streams and charged response +queue bytes. Fields are individually atomic; concurrent snapshots are approximate. [Back to TOC](#table-of-contents) ## Threading contract -Distilled from -[`specs/architecture/05-cross-cutting.md`](specs/architecture/05-cross-cutting.md) -§5.1 and DR-008 -([`specs/architecture/11-decisions/DR-008.md`](specs/architecture/11-decisions/DR-008.md)): - -1. **Public methods on `webserver` are thread-safe and re-entrant from - inside a handler.** Two exceptions: `stop()` and `~webserver()` - **deadlock** if invoked from a handler thread, because they wait for - that very thread to drain. `stop_and_wait()` delegates to `stop()` - and carries the same deadlock risk. Stop the server from a different - thread, or signal an external stop loop. v2 provides both `stop()` - (signal and return) and `stop_and_wait()` (signal and drain until - all in-flight handlers finish). -2. **Handlers run concurrently on libmicrohttpd worker threads.** The - same lambda or `http_resource` instance is invoked from many threads - at once. Any state you share — counters, caches, file handles — must - be synchronised on your side. The library does not synchronise user - state for you. -3. **`http_request` is single-threaded per request.** Sharing one - `http_request` across threads is undefined; the per-request arena - makes no guarantees outside the calling thread. -4. **`http_response` is value-typed with exclusive ownership.** - Returning it transfers ownership into the dispatcher. There is no - shared mutable response object. -5. **User-supplied callbacks** — `log_access`, `log_error`, - `not_found_handler`, `method_not_allowed_handler`, - `internal_error_handler`, `file_cleanup_callback`, PSK / SNI / ALPN - callbacks, and any registered `render_*` — may run concurrently on - multiple threads. Implementations MUST be thread-safe. +The native [architecture](specs/architecture/v3/architecture.md) and public +contracts distinguish executor-owned work from synchronized handles: + +1. Server methods are thread-safe unless documented otherwise; lifecycle calls + (`listen()`/`stop()`) belong to one controlling thread. Routes close at listen, + while hook and peer-policy mutation remain runtime-safe. +2. Different requests may invoke the same callable/captured state concurrently. + Synchronize application state. An exchange's decisions, reader and writer + run on its handler executor. Copy request data needed outside that lifetime. +3. `request_stop()` is nonblocking, idempotent and handler-safe. It releases + listeners and disconnects active exchanges. `stop()` additionally closes + engines and joins workers; call it from a controlling thread outside counted + work. The destructor performs stop. Keep application captures alive until + this join completes. +4. `begin_drain(budget, ticket)` stops accepting new work and initiates graceful + rundown without waiting. For HTTP/1, in-flight work flushes, idle connections + close and unstarted pipelined heads are dropped; WebSockets begin Close 1001. + The positive budget bounds the ticket's wait. A server supports one drain; + calls before listen, after stop or after a previous drain return invalid_state. +5. `ticket.wait(result)` reports `completed` or `deadline_expired` with the + remaining count at expiry. Waiting from work counted by that drain returns + `would_deadlock`. Tickets retain their counted scope after server destruction. + Stop during a drain can complete it before expiry; an expired result remains + expired after cancellation unwinds. + +### Suspension and cancellation + +`x.suspend(resume_signal&)` obtains a signal for a pending decision. Copy the +owning signal to application work and `co_await signal.wait()` or +`signal.wait_for(duration)` on the handler executor. Another thread calls +`signal.signal()`; the result distinguishes resumed, timeout and cancellation. +Exchange disconnect wakes pending operations. `x.cancellation()` gives a fan-out +stop token whose `cancelled()` awaitable throws `cancelled_exception`; ordinary +body/writer operations report typed cancellation. Use RAII to retire pending +application registrations on every path. + +Shutdown can cancel pending work but cannot make arbitrary blocking application +code cooperative. Respect cancellation/deadlines in application operations and +retain their captures until retirement. The [lifecycle example](examples/lifecycle.cpp) +shows resume, timeout, cancellation and drain without leaking an `exchange&` to +another thread. External PSK callbacks have their own explicit retirement +contract described under [Authentication and TLS](#authentication-and-tls).

The response - returned by `internal_error_handler` is sent to the client; if no - custom `internal_error_handler` is configured, a default 500 with - the **fixed body `"Internal Server Error"`** is sent - (DR-009 Revision 1, CWE-209 fix — exception text often contains - file paths, SQL fragments, or attacker-influenced input and must - not cross a process boundary to an untrusted client). To restore - the v1 behaviour of including the exception message in the body - for development, set `.expose_exception_messages(true)` on the - builder. The verbatim message is still surfaced via the - `log_error` callback and to any configured - `internal_error_handler` regardless of the flag. -2. **A handler that throws something other than `std::exception`** is - also caught, with `"unknown exception"` substituted for the message. - The same default body (`"Internal Server Error"`) applies; the - `"unknown exception"` sentinel reaches the wire only when - `.expose_exception_messages(true)` is set. -3. **Library-internal failures during dispatch** (allocation, body - materialisation) flow through the same `internal_error_handler` path. -4. **If `internal_error_handler` itself throws**, the library logs and - sends a hardcoded 500 with an empty body. There is no third level of - fallback. -5. **`feature_unavailable` is a normal `std::runtime_error`** — no - special status mapping. Catch it explicitly if you want to map it to - a 503 or similar; the library does not. -6. **There is no throw-as-status idiom.** A handler that wants to - return 404, 400, etc. builds the response by value (see - [Response](#response)): - `return httpserver::http_response::empty().with_status(404);`. - -Install custom error handlers on the builder: - -```cpp -auto cfg = httpserver::create_webserver(8080) - .not_found_handler([](const httpserver::http_request&) { - return httpserver::http_response::string("nope").with_status(404); - }) - .method_not_allowed_handler([](const httpserver::http_request&) { - return httpserver::http_response::empty().with_status(405); - }) - .internal_error_handler([](const httpserver::http_request&, std::string_view what) { - // CWE-209: 'what' may contain file paths, SQL fragments, or - // attacker-influenced input.

Note that the snippet above — which echoes `what` -verbatim to the wire — is illustrative of the explicit-handler case; -the **default** (no `internal_error_handler` configured) path now -sends a fixed body, and only the `log_error` callback receives the -verbatim message. To restore the v1 verbose-body default for -development, chain `.expose_exception_messages(true)` on the builder -(see [Custom error handlers](#custom-error-handlers)). +Check `outcome.ok()` before consuming a successful operation's outputs. +`outcome.code()` is the stable semantic discriminator and `message()` is a +human-readable diagnostic.

The `handler_exception` +chain may supply a recovery response; otherwise the dispatcher synthesizes a +bare 500 with no fixed text body. Returning without a terminal decision also +synthesizes 500. A handler exception after commitment aborts the response through +the protocol engine; it cannot replace the accepted head. Disconnect cancellation +is a quiet end, reported through completion state rather than a new error page. + +To answer 400/404/503 intentionally, call `respond`, stream a response or return +a synchronous value with that status. Exceptions do not map automatically to +HTTP status codes. Keep exception details in application diagnostics and avoid +echoing internal data to clients.

The unsigned +64-bit `registration_generation` accompanies it in every `socket_interest` and +`readiness_event`. A host saves the **pair** with each native registration and +copies that pair into queued callbacks. Default-constructed values do not +authorize registration; only instructions published by the driver do. + +A socket lifetime change changes its generation; an interest-mask change for +the same live socket need not. No previously issued pair may be reused during +one driver lifetime, including on counter exhaustion. The library must stop or +fail rather than wrap into an old pair. Dispatch ignores removed registrations +and generation mismatches. Reusing a native descriptor cannot revive an old +callback. The wake registration follows the same identity rules. + +`native_handle` carries a `std::uintptr_t` value, a `native_handle_kind` +(`posix_descriptor` or `winsock_socket`), and an explicit `valid` flag. Descriptor +zero is valid. A host must preserve pointer-width socket values on Windows and +must not use a numeric sentinel to override `valid`. An implementation publishes +only valid, correctly typed handles. The carrier is for host readiness +registration only; it is neither identity nor permission to perform socket I/O. + +`interest_snapshot` owns its `sockets` vector, optional `wake` registration, +and optional `next_deadline`. Each snapshot is a complete, coherent set of +instructions: omission means unregister, and changed masks mean update the +host registration. Published pairs are unique across sockets and wake. +Snapshots can be copied and retained independently, including after driver +destruction. Their native handles remain borrowed and library-owned; retaining +a snapshot does not extend any handle lifetime. Never read, write, or close a +published handle. A saved registration does not authorize use after removal or +teardown. The host must remove registrations before awaiting more callbacks +after reconciling a newer snapshot; any already queued stale callbacks retain +their old pairs for filtering by dispatch. + +## Host loop, time, and dispatch + +One controlling host thread serializes snapshot acquisition, reconciliation, +waiting, and dispatch for each driver. Calls for that driver must not overlap or +recurse. Concurrent or recursive dispatch is rejected with +`http::outcome_code::invalid_state` **before consuming events**. Independent +servers may dispatch concurrently, and route workers may run concurrently. +No application handler runs under an internal I/O lock. Event order does not +establish protocol order: the private exactly-once terminal claim and +connection-owner serialization remain authoritative (TASK-099). + +Deadlines and the `now` argument use `std::chrono::steady_clock` in the same +clock domain. Host samples must be nondecreasing. `nullopt` means no deadline; +there is no synthetic periodic timeout. A deadline at or before `now` requires +immediate dispatch, even with an empty event span. The library publishes its +actual nearest outstanding deadline; acquiring snapshots must not reset +protocol Close or server drain anchors. + +Dispatch never waits for network readiness or application completion. Translate +native readable/writable notifications into the corresponding Boolean flags; +translate hangup/peer closure into `closed` and readiness errors into `error`. +These indications may coexist with readable/writable flags. They convey no +native error numbers or platform-specific flag values. The engine determines +the resulting protocol/transport outcome. Duplicate or spurious notifications, +including events with all flags false, are permitted and do not imply additional +completions. Empty batches are permitted for timers and pending library work. + +Obtain an initial snapshot before waiting. After **every successful dispatch**, +obtain and reconcile a fresh snapshot before waiting again. A failed dispatch +may have consumed part of a batch unless the documented rejection rule says +otherwise. Stop driving on a failed outcome: do not replay the batch or reconcile +fresh interests as if dispatch succeeded. Recovery requires an explicitly +documented adapter recovery API; absent one, unregister and shut down through +the owning server. No such recovery API is provided by this header. + +Snapshot acquisition can allocate and throw `std::bad_alloc`; it is not +allocation-free and has no outcome return. Treat that exception as a stopped +host loop, unregister, and arrange owner shutdown. Operational dispatch failures +use `http::outcome`; any allocation exception escaping dispatch has the same +stop-and-shutdown posture. The interface is not `noexcept`. + +The driver is owned by its server; `native_server::readiness()` defines the +borrowed-pointer lifetime above. No host call may overlap driver destruction. +Unregister host interests and coordinate callback quiescence before teardown; +never dispatch queued callbacks to a destroyed driver. + +## Wake publication and registration race + +An active external driver that can receive asynchronous library work must +publish a usable, readable wake registration (`readable=true`, `writable=false`) +or return a documented configuration failure before listening. Absence is +permitted only in a documented inactive state in which worker submissions +cannot arrive. Wake signals pending library work and changes to interests or +deadlines, including worker-thread submissions. Hosts must not need periodic +polling to make that work progress. + +Pending work remains authoritative across the **publish/register/wait race**: +work arriving after a snapshot but before host registration must leave a +notification observable when the host registers and waits. Implementations +must preserve this condition through wake draining/rearming and registration +changes, including work arriving during dispatch. Wakes may coalesce or be +spurious. On wake notification the host calls dispatch, passing the wake pair +as a readable event; the library drains and rearms its own source. The host +must not read or close the wake handle. The managed poll backend's idle +fallback is not part of this contract. + +Existing `server_options::validate` remains the pre-listen configuration +boundary for PRD-V3N-REQ-016. The concrete adapter must reject incompatible +loop/configuration combinations there; the `loop()` option selects external mode and rejects combinations whose +engines do not support host readiness dispatch. + +## Host-loop sketch + +The host-specific functions below reconcile registrations and translate OS +notifications using the saved pairs. They are pseudocode, not library APIs. +`host_wait` accepts an optional absolute steady-clock deadline, returns an owned +event batch, and returns immediately for an already due deadline. + +```cpp +// driver is a borrowed server-owned readiness_driver reference. +try { + auto snapshot = driver.interests(); + host_reconcile(snapshot.sockets, snapshot.wake); + while (host_running()) { + std::vector events; + const auto before_wait = std::chrono::steady_clock::now(); + if (!snapshot.next_deadline || *snapshot.next_deadline > before_wait) { + events = host_wait(snapshot.next_deadline); + } + auto result = driver.dispatch(events, std::chrono::steady_clock::now()); + if (!result.ok()) { + host_record_failure(result); + break; + } + snapshot = driver.interests(); + host_reconcile(snapshot.sockets, snapshot.wake); + } +} catch (const std::bad_alloc&) { + host_record_allocation_failure(); +} +host_unregister_all(); +owner_shutdown(); +``` + +## Portable consumer compilation + +Compile the same `test/headers/consumer_v3_readiness.cpp` bytes and public +headers on each native platform.

Callback arguments remain valid +through that invocation; retaining identity or context requires owned copies. + +## Execution and exclusive session handoff + +Use a dedicated, bounded **handshake lane**, distinct from the I/O owner and +ordinary route workers. The OpenSSL handshake call and its synchronous PSK +trampoline execute on this lane. The trampoline submits application lookup to +a separately bounded **lookup lane** and waits only until completion, +cancellation, or the absolute handshake deadline. Both lanes prohibit executing +submitted work inline on the owner. Separating them allows the trampoline to +return failure when arbitrary application lookup ignores cancellation. + +At most one worker owns a session/SSL at a time. Before dispatching a step, the +owner transfers owned input and output batches and exclusive session access. +While the step is outstanding, the owner cannot call SSL, feed/drain its BIOs, +or destroy the session. Worker code cannot borrow pending application I/O +buffers. The worker returns owned output batches and a step result; the owner +regains provider access only after retirement of that step. Cancellation and +logical connection close do not authorize concurrent SSL teardown. + +Publish completion through the owner's serialized queue, checking connection +and attempt generation plus terminal state before applying it. Owner deadline +processing remains independently runnable during lookup. A stale completion +retires its owned session/batches without restarting I/O or accessing a retired +adapter. Exclusive ownership also applies to provider cleanup after a failed +or cancelled step. + +## Admission, deadlines, and outcomes + +Set finite limits for active handshake jobs, running lookups, queued lookups, +and aggregate lookup attempts per handshake. Include any queued handshake +steps in finite admission accounting. Admission never blocks the owner; +exhaustion rejects the handshake with a typed, redacted resource-limit result. +Use a fixed worker budget, never a thread per handshake. Queued work consumes +the same absolute deadline; workers check deadline/cancellation before invoking +application code. Retrying a provider step never resets the deadline. + +Accept success only before the deadline and before cancellation or terminal +completion wins. The owner's terminal arbitration publishes exactly one +outcome. Even if the worker observed timely success, the owner discards it when +its deadline or terminal check loses the race. Late success cannot establish a +connection, deliver authenticated application data, or restart I/O. + +Provide typed, library-owned outcomes for application rejection, provider +failure, timeout, cancellation and admission failure. Exceptions are caught at +callback boundaries and converted to redacted failure. Never log identity, +key material, exception text, or raw provider errors. Diagnostics expose outcome +categories, not application credential data. + +## Cancellation, retirement, and rotation + +Cancellation requests cooperative stop and wakes the trampoline's bounded wait. +It cannot forcibly interrupt arbitrary application code. Logical handshake +timeout does not prove that lookup/provider work terminated. The owner can +publish timeout promptly while retiring the outstanding handshake step later; +drain must report incomplete work if retirement misses its deadline. Do not +promise immediate reclamation or silently join an unresponsive lookup on the +owner. + +A late lookup owns only copied identity/context, retained callback/runtime +ownership and its result storage. It cannot access SSL, the adapter, application +buffers, or a stack frame of the waiting trampoline. Completion storage is +owned independently of that wait. Discard and wipe a late key immediately when +lookup eventually returns. Unreturned lookups keep consuming bounded running +capacity: timeouts cannot open replacement capacity for still-running work. +Applications must honor stop/deadline and keep the runtime alive through +retirement. Runtime teardown must expose outstanding work rather than hiding +an unbounded join on the owner. + +Rotation affects new acquisitions only. An attempt retains the same selected +immutable generation, callback/runtime and deadline across repeated provider +callbacks. Independent handshakes can invoke the same callback concurrently; +applications synchronize mutable state. Within an attempt, coalesce duplicate +lookup for the same TLS version/identity, including concurrent callers. A mutex +serializes that attempt's bounded waits; independent attempts remain concurrent. +Bound the number of distinct version/identity lookups. Any retained +per-attempt key is owned secure storage wiped at retirement; do not introduce a +global plaintext-key cache. + +## Identity representation and key ownership + +Identity is an opaque byte span for the duration of lookup. TLS 1.3 supplies an +explicit length; copy those bytes without text normalization. TLS 1.2's provider +callback exposes a NUL-terminated string, so this profile supports textual +identities only. Embedded wire NULs cannot be detected with `strlen()`; do not +promise lossless binary identity semantics. If strict wire-NUL rejection is +required, it needs a separately verified wire-level check before lookup. + +Validate finite identity/key profile bounds before lookup admission. For the +selected OpenSSL 3.5.9 provider: + +| Version | Identity constraint | Key storage ceiling | +| --- | --- | --- | +| TLS 1.2 | 256 wire identity bytes; callback exposes a C string | 512-byte server callback buffer | +| TLS 1.3 | Explicit-length identity; enforce a finite profile bound | 512-byte `SSL_SESSION` PSK storage | + +The TLS 1.3 ceiling comes from `TLS13_MAX_RESUMPTION_PSK_LENGTH` and +`ssl_session_st::master_key` in +[OpenSSL 3.5.9 ssl_local.h](https://github.com/openssl/openssl/blob/openssl-3.5.9/ssl/ssl_local.h), +and the array-size check in +[SSL_SESSION_set1_master_key](https://github.com/openssl/openssl/blob/openssl-3.5.9/ssl/ssl_lib.c). +The similarly named `SSL_MAX_MASTER_KEY_LENGTH` in `include/openssl/prov_ssl.h` +is 48, but **does not bound this session PSK storage**. Local characterization +accepts 512 bytes and rejects 513; this corrects the saved plan's 48-byte +assumption. Neither the public 48-byte constant nor the legacy PSK callback +buffer alone establishes TLS 1.3 capacity. Future providers must supply their +own verified bounds. A tighter application policy, such as 48 bytes, is allowed +but must be labeled separately. Reject empty/oversized keys without truncation; +recheck actual results against `maximum_key_bytes` before copying to OpenSSL. + +`secure_bytes` owns move-only storage. Wipe it on rejection, cancellation, +timeout, overwrite and destruction. Avoid reallocations that leave unwiped +copies; moving storage must transfer ownership without duplicating plaintext. +The lookup-return/timeout race must wipe whichever result loses arbitration. +Moving library storage does not erase OpenSSL's own copies. The provider's +TLS 1.2 path copies the callback key and cleanses the temporary buffer in +[`tls_process_cke_psk_preamble()`](https://github.com/openssl/openssl/blob/openssl-3.5.9/ssl/statem/statem_srvr.c). +TLS 1.3 find-session invocation is synchronous in +[`extensions_srvr.c`](https://github.com/openssl/openssl/blob/openssl-3.5.9/ssl/statem/extensions_srvr.c). +Provider-owned copies retain their session lifetime and cleanup obligations; +library zeroization alone cannot prove all copies disappeared. + +## Evidence boundary + +`test/unit/tls_psk_contract_test.cpp` observes ClientHello retry/resumption, the +TLS 1.2 callback's calling thread, blocking interval and actual key buffer, and +the selected provider's session-key capacity using memory BIOs and synthetic +test credentials. It remains distinct provider-characterization evidence. The TASK-135 adapter and +runtime tests now cover admission, exclusive handoff, cancellation/deadline races, +late-result wiping and retirement against this contract. Local acceptance is recorded in +[the TASK-134 evidence report](task-134-psk-contract-evidence.md). + +## Installed runtime policy and evidence + +`tls_psk_runtime_options` defaults to two handshake workers and two lookup +workers, with sixteen additional outstanding slots on each lane and a five +second handshake timeout. Validation permits 1–64 workers per lane, 0–65536 +additional slots and a timeout greater than zero and at most 24 hours. +Admission counts running and queued jobs together (`workers + queue`); a reserved +worker slot may still be queued while its worker wakes. Running callbacks never +exceed the worker count. Queued and running jobs share one absolute deadline. +The adapter uses the earlier of the operation deadline and the scheduling +runtime's finite handshake deadline, including when the operation supplied no +explicit deadline. A mixed snapshot uses its default PSK runtime, or the first +PSK host's runtime, for handshake scheduling; the selected host owns its lookup +runtime. Runtime admission does not execute inline. + +`stop()` rejects new work and signals cancellation. Call `stop()` before +`drain(deadline)`: true means both lanes have retired all jobs and workers; +false reports incomplete retirement. Destruction signals stop without joining. +Detached workers retain their own lane/job storage until return, and held +application code continues to consume capacity. Applications must release held +callbacks and keep captured resources valid until retirement. Callback stop +handlers must themselves be nonblocking, as for ordinary `std::stop_token` use. +Lookup completion retains copied identity/context, callback and independently +owned result storage; its cancellation token combines connection stop, runtime +stop and logical lookup retirement. A late key is cleansed before release. + +`tls_psk_attempt` retains at most the configured number of distinct lookup +results. Accepted keys may remain in its secure per-attempt cache for duplicate +provider callbacks; a temporary secure copy transfers each key to OpenSSL. +The cache is wiped at handshake success/failure or session retirement, never +shared across connections or credential generations.

The positive case uses the unmodified provider. +The installed aggregate contains native objects only. TLS-off has no MHD, +GnuTLS or OpenSSL dependency, probe or pkg-config requirement. TLS-on exposes +selected OpenSSL flags through `Libs.private` for static consumers while keeping +backend headers out of the installed API. Platform/thread libraries also appear +in `Libs.private`.

Each successful `replace(config)` builds +and validates a complete immutable generation before atomic publication. Rejected +material (invalid host/default index, malformed PEM, mismatched key or unsupported +ALPN) leaves the previous publication active. The store retains provider objects, +not the PEM input. Caller buffers and handles may die after configuration; the +listener retains the store and accepted handshakes/sessions pin their generation +through retiring I/O completions. No global credential store exists. + +Host names use exact canonical DNS matching, with case folding and a final dot +removed. Unknown or absent SNI selects `default_host` (zero by default). Each +listener has its own explicit store; sharing is intentional only when the same +store is assigned. Certificate and initial mTLS ALPN may contain `h2`, +`http/1.1`, or both; empty ALPN selects ordinary HTTP/1 fallback. An advertised +protocol must be enabled in every listener bound to the credential store. PSK +profiles retain HTTP/1-only ALPN and reject `h2`. Later +publication cannot negotiate a disabled ALPN; wire requests for a disabled H1 +version are rejected before routing. `exchange::tls()` and request hook contexts +carry library-owned immutable authenticated peer metadata; plaintext uses null, +and anonymous certificate TLS has no client certificate identity. + +Native admission reserves its connection budget before constructing TLS state. +Handshakes share the existing bounded provider lane and use an absolute +`timeouts().handshake` deadline. A stalled peer cannot reach an H1 reader or +handler. Drain cancels pending handshakes and stops new admission; established +H1 exchanges retain ordinary drain semantics. `request_stop()` remains safe from +handlers; call blocking `stop()` from the coordinator. External hosts must keep +advancing published readiness, wake and timer deadlines, including empty dispatch +when only a deadline is due (the same contract as plaintext). + +Pure structural option errors take precedence in both loop modes. An unavailable +build/protocol/profile returns `not_supported`. TLS-on missing/unpublished +credentials or incompatible ALPN return `invalid_argument`. TLS-off exposes the +same declarations, returns `not_supported` from `replace` and rejects valid TLS +requests before binding. Every endpoint binds before admission activates; failure +on a later bind synchronously releases earlier endpoints and reports no bound +ports. A bind failure is terminal for that server instance. + +TASK-193 supplies public certificate/default/SNI configuration and generation +lifetime safety. TASK-194 extends the same store to initial mTLS, HTTP/1 external +PSK and ACME, and exercises live listener rotation through installed packages. +Private profile suites remain supporting protocol evidence. + +Run the installed certificate capability matrix after staging a package: + +```sh +python3 scripts/check-v3-public-tls.py --prefix /installed/package \ + --provider-prefix /selected/openssl --build /identified/build \ + --tls yes --output /fresh/public-tls-receipts +``` + +The same source compiles in TLS-off and TLS-on lanes. The runner checks staged +public header origins, pkg-config identity, shared/static linkage and dependency +graphs; independent Python SSL clients verify chains, named hosts, SNI/default +certificates, ALPN, H1 status/version/body and lifecycle behavior in both loops. +Unknown/absent SNI checks verify the chain and compare the selected certificate +with its independently hostname-verified named certificate. TLS-off runs the same +configuration code and requires typed unavailability. Nonlocal platform checks +remain CI/v3-PR owned. + +## Public initial client authentication, external PSK and ACME + +`server/tls_credentials.hpp` supplies provider-neutral host trust, authentication, +owned keys and a bounded callback runtime. Set `tls_host_credentials::profile` +and the listener's `options.tls().profile` consistently. For mTLS, set +`trust_roots_pem` to the client CA roots. `mutual_tls` defaults to `require`; +explicit `client_auth.mode = tls_client_certificate_mode::request` verifies any +presented chain while allowing anonymous peers. `require` refuses absent or +untrusted client chains. Set the same resolved mode on the listener. Authentication +is initial-handshake only. Exchanges and request hooks own immutable verified +leaf identity, fingerprint and validity metadata. + +A bound store rejects publication that contradicts any active listener's profile, +resolved mode or enabled HTTP/1 policy. Bind registration and publication share +one private writer transaction; a concurrent writer cannot downgrade authentication +between validation and admission. Compatible listeners hold independent leases; +stopping admission releases that listener's lease. Already accepted sessions keep +their pinned generation. Invalid material and policy leave the active generation +unchanged. Mixed profiles in one store cannot attach to a listener configured for +one contradictory profile. + +For HTTP/1 external PSK, create `tls_psk_runtime` with finite `lookup_workers` +(1–64) and `lookup_queue` (0–65536), supply `tls_psk_config::lookup` and its shared +runtime, and set the host/listener profile to `external_psk`. Certificate/key/trust +material must be empty for PSK. Return `tls_psk_result` with an accepted status and +move-only `tls_psk_key` built from owned bytes. Identity/context references last +one invocation; retain copies when needed. TLS1.3 identities are binary; TLS1.2 +exposes textual NUL-terminated identities. The context owns canonical selected +host, generation identity, absolute monotonic deadline and cancellation token. +Callbacks can run concurrently and must synchronize mutable captured state. + +The lookup runtime is distinct from native server-owned provider workers. It +counts active and queued callbacks together; ignored cancellation retains a slot +until callback return, including across rotation. Late keys are wiped and never +route requests. `request_stop()` is nonblocking. Call it before +`wait_retired(absolute_deadline)` to observe actual callback retirement: timeout +means application work remains; waiting from that runtime's callback returns +`would_deadlock`. Destruction requests stop without joining arbitrary application +code. Captured resources must be owned through retirement. A native handler's +`request_stop()` or `begin_drain()` does not stop a shared application runtime; +one server stopping cannot disable another server using that runtime. + +Normal certificate sessions have a host/context namespace. Same-generation +resumption may reuse authentication; replacements create fresh contexts, so an +old session cannot bypass the replacement or cross host/store identity. External +PSK authentication differs from ticket resumption: PSK profiles and ACME disable +tickets/session caching. Every ACME handshake sends its challenge certificate. +Application 0-RTT remains disabled; early requests never enter routes. + +`tls_credentials::publish_acme(tls_acme_challenge)` validates a supplied challenge +certificate/key, canonical DNS host, 32-byte authorization digest and future +absolute system-clock expiry no later than certificate expiry. The certificate +must have exactly one matching DNS SAN and one critical ACME authorization digest +extension. `remove_acme(host)` is canonical and idempotent. Publication validation +is independent of listener port. Selection requires matching exact canonical SNI, +sole `acme-tls/1`, TCP, and the socket's actual local port443. Other ALPN offers and +ordinary HTTP use normal credentials; challenge sessions cannot route HTTP. This +API performs no certificate issuance or challenge-client orchestration. + +TLS-off installs identical declarations and secure key operations, with typed +`not_supported` for credential/runtime/ACME availability. Certificate and initial +mTLS profiles support public H2/H3 listeners; external PSK remains HTTP/1-only. The installed rotation +example takes `certificate-directory managed|external port`, opens a real public +listener and accepts `replace`, `invalid` and `stop` on stdin. Its independent +installed witness holds a usable connection across rotation and validates the +new certificate plus rejected-publication preservation. + +Public HTTP/2 uses the same native server, route table, hooks, peer policy and +exchange API as HTTP/1. See [the public example](../examples/http2.cpp) and +[TASK-195 design](../specs/architecture/v3/TASK-195-design.md). TLS-off +configuration rejects HTTP/2 before binding. TLS 1.2 HTTP/2 rejects forbidden +ciphers before publishing request hooks. + +Connection wire operations run serially; each stream has its own handler +affinity on the configured workers. A running handler can occupy one worker, +so applications should keep handlers cooperative and size the worker pool for +their concurrent work. Receive credit follows body consumption. Configured +server limits bound listener, connection and stream descendants, including +header copies, body rings, output and WebSocket storage. Header, SETTINGS, +body-idle, suspension, write-idle, WebSocket close and drain timers use native +readiness deadlines without periodic polling. + +RFC8441 Extended CONNECT upgrades one stream and permits ordinary siblings. +Native drain publishes staged GOAWAY, finishes accepted work, and cancels +remaining requests and WebSockets at its absolute deadline. A retained ticket +keeps the original deadline result; its remaining count describes unfinished +work at expiry, even after actual retirement. A counted handler cannot wait +on its own drain ticket. + +## Current packaged capability evidence + +The [TASK-199 report](../test/installed/task199-capabilities.md) identifies the +current archive/install/tool inputs and independent receipt validation for +shared/static consumers in managed/external modes. Supported TLS/H2/UDP-H3 +configurations bind and complete exchanges; missing credentials and invalid +configurations retain their separate pre-bind rejection checks.

The public default +limits each H2 connection to 128 stream openings per second. Epochs stay below +that allowance without changing production policy or adding artificial pacing. +H3 has sixteen live-request seats and bounded lifetime stream records, so its +full workload uses +1024 connection epochs, each with four concurrent warmup requests followed by +four measured streams: **4096 actual warmup requests** and 4096 measured requests. +Every H3 epoch performs verified connection setup, completes warmup, reuses that +connection for measurement, then closes it.

Concurrency 8 can produce H3_EXCESSIVE_LOAD +refusals; concurrency 4 stays within the default admission capacity. This +benchmark changes no production resource policy.

H2/H3 epoch warmup follows concurrency, independent of the +H1 warmup option. Overrides appear in the receipt; any deviation from defaults +is labelled a reduced/custom workload rather than full acceptance evidence. + +Timestamps are integer `time.monotonic_ns()` nanoseconds with clock resolution +recorded. A request starts immediately before dispatch and ends at complete +response receipt. Clients verify protocol negotiation, certificate trust and +`a.example`, status 200, exact payload and run/request identity. Setup and all +warmup samples are retained separately. Each measurement window starts after +successful warmup and ends at its last measured completion. Duration is the sum +of nonoverlapping measured windows in seconds; throughput is successful measured +completions divided by that sum, in requests/second. For H2/H3 this excludes each +epoch's handshake, warmup and close, and is **not whole-process wall throughput**. +Whole-process wall seconds are also recorded. Differing protocol concurrency +and connection reuse settings make these observations unsuitable for a direct +protocol performance ranking.

Validation requires +exactly one SAN extension with exactly one DNS entry matching the canonical name, +and exactly one critical `1.3.6.1.5.5.7.1.31` extension whose value is precisely +`04 20` followed by the expected digest. Digest comparison uses `CRYPTO_memcmp`. +Strict bounded PEM parsing rejects multiple leaves, trailing material and key +mismatches. Certificate validity must include publication time; the deadline +must not extend beyond certificate expiry. Provider diagnostics and caller PEM +are not included in failure outcomes or retained in published state. + +Publication requires an initialized normal snapshot. Publish replaces one exact +name and removal is idempotent for absent valid names. Successful changes consume +one generation; invalid candidates, malformed removals, no-op removal and +generation overflow preserve active state. Challenges occupy a separate immutable +map, with contexts shared by snapshot copies. All writers use the existing +publication mutex. Normal replacement copies the latest challenge map while +holding that mutex, preventing lost concurrent updates. Expiry is checked at +lookup, including against previously acquired snapshots; no cleanup thread is +required. A selected handshake may finish after its deadline. + +The session and adapter accept defaulted provider-neutral `tls_handshake_context` +metadata. Only trusted TCP/local-port 443, exact canonical SNI and a complete ALPN +extension offering solely `acme-tls/1` can select a challenge. Unknown transport, +unknown port, other ports, QUIC, missing/nonmatching SNI, mixed offers and malformed +extensions cannot expose a challenge. A sole offer without an eligible challenge +fails before certificate delivery, including normal hosts with empty ALPN and +snapshotless sessions. Ordinary HTTP selection and generation/host resumption +continue through the existing path. Public listener integration remains a later +task; this task does not infer the listener port from peer-controlled input. + +Challenge selection explicitly reapplies certificate ciphers, clears external +PSK callbacks and disables client-certificate verification. It disables early +data, tickets, caching and renegotiation through context and per-SSL restrictions, +a non-resumable-session callback and a fresh per-handshake session-ID namespace. +A TLS 1.3 HelloRetryRequest retains the already-selected context and namespace; +its second ClientHello must keep the exact name and sole challenge offer. +Challenge application reads/writes fail with protocol_error and zero bytes, +while TLS close_notify shutdown remains usable. + +## TDD and behavioral observations + +| Probe | RED | GREEN | +| --- | --- | --- | +| Publication with rejection-only declarations/stubs | 3 failed checks across two tests | Valid ownership/publication/removal and invalid-candidate matrix pass | +| Real ClientHello selection with metadata accepted but ignored | 4 handshake assertions failed, including ordinary mTLS and external PSK initial contexts | TLS 1.2 and 1.3 certificate/ALPN selection and authentication isolation pass | +| Lifetime/adapter selection | 2 failed old-snapshot/adapter handshake assertions | Acquired handshakes, registry destruction, retirement and ordinary data pass | +| TLS 1.3 retry crossing challenge expiry | 2 failures: ordinary serial 101 delivered instead of challenge serial 303, with wrong digest | Same selected challenge remains pinned; fresh lookup is expired | + +Behavioral RED logs: `/private/tmp/task136-credentials-red.log`, +`task136-psk-red.log`, `task136-lifetime-red.log`, `task136-retry-red.log`. +Initial compiler errors while bringing up test declarations/fixtures are not +counted as behavioral RED evidence. + +Independent OpenSSL peers use separate client SSL objects and memory BIOs with +fragmented transfers. They inspect the received leaf serial, critical digest +extension, negotiated ALPN, certificate-message count, SNI acknowledgement, +actual tickets and session-reuse disposition. Challenge peers disable PKIX +verification to permit the critical ACME extension; they directly validate the +observed challenge identity instead. Ordinary verified-peer resumption and +rotation regressions remain in the focused suite. + +Barrier-controlled writers publish independent names concurrently with ordinary +replacement. A separate simultaneous publication/removal/replacement race proves +that removed names cannot be restored by a normal replacement. Readers pin old and fresh generations while replacement runs, +correlating generation with observed serial, digest and ALPN. Distinct replacement +digests prove coherent old/new contexts. Invalid writers leave the exact active +snapshot and generation unchanged. Both removal/replacement orderings preserve +unrelated challenges. Retirement tests observe weak snapshot/context ownership, +a terminal claim that cannot be taken twice, zero pending raw children and zero +owner completions after executor drain. Established ordinary application data +still exchanges after publication/removal. The retry-expiry test first observes +an actual HelloRetryRequest, then advances its private selection clock exactly +to the challenge deadline. A fresh lookup and fresh ClientHello reject the +expired challenge while the selected handshake completes with its pinned leaf. +The internal registry copies its selection clock into each immutable snapshot; +the default remains `system_clock::now`.

Task and index remain In Progress; +the runner owns validation, commits, merge and cleanup. No staging or commit +was performed during implementation. + +## Implemented boundary + +The guarded private frame parser consumes the client magic, nine-byte headers +and one frame/event at a time. The caller retains any suffix and releases an +outstanding event before continuing. Non-control payload storage is admitted +against `body_buffer_bytes` before allocation and retained through event +ownership. SETTINGS uses six-byte scratch and a bounded transaction containing +final standard values plus the minimum/final HPACK table-size changes. PING +uses eight-byte scratch. Unknown payloads are skipped without allocation. +Oversized headers fail at nine bytes before payload admission. Frame-size +violations may be escalated to a connection error; malformed PRIORITY provides +a stream-scoped, completely discarded frame with subsequent framing intact. +Continuation ordering and EOF during a field block are enforced. + +Each connection owns independent peer/local/queued-local state and two HPACK +directions. Peer SETTINGS changes the encoder; FIFO ACK of local SETTINGS +changes the decoder. Invalid earlier duplicates remain errors, and truncated +transactions cannot change peer state or generate an ACK. Optional advisory +limits start unlimited; omitted advisory values in a local update retain the +last advertised value. Peer MAX_FRAME_SIZE never raises the inbound limit; +all control output is smaller than the minimum legal peer frame size. Legal +large table settings change logical limits without proportional allocation. + +Server output starts with SETTINGS. Its first exposure to the output owner +commits the local snapshot and starts the injected monotonic ACK deadline; +construction and unexposed queued updates start no clock. Exact deadline expiry +returns SETTINGS_TIMEOUT. Callers must use the same monotonic clock for output, +input and timeout checks; default epoch arguments support deterministic private +fixtures. ACK with no committed pending update is a connection PROTOCOL_ERROR. + +Private defaults are 64 control slots, 4 KiB reserved response-output capacity, +16 queued-or-pending local SETTINGS and 64 completed frames per pump turn. +Smaller test limits are validated before input. `begin_turn()` renews work +allowance; yielding consumes no suffix and preserves protocol state. The +4 KiB charge includes an independent 17-byte terminal GOAWAY path. Peer control +queue overload maps to `limit_exceeded`/ENHANCE_YOUR_CALM; local update admission +returns `limit_exceeded` without corrupting the live connection. SETTINGS/PING +progress despite exhausted DATA buffering. An exposed control frame finishes +before terminal GOAWAY, preserving its borrowed storage and wire boundary. +Terminal failure is sticky and releases input reservations; output reservation +is released when terminal output is consumed or the connection is destroyed. +Hierarchical refusal rolls back without residue. No uncharged error output is +exposed when initial reserve/configuration admission fails. + +The private TLS enum copies actual provider-negotiated ALPN only after a +successful authenticated handshake; failed/uncompleted handshakes stay unknown. +The adapter publishes it atomically before completing its successful handshake. +Real OpenSSL independent peers cover TLS 1.2/1.3 h2, HTTP/1.1, absent ALPN and +failed negotiation. A completed h2 adapter decrypts five-byte input fragments +into the machine and encrypts its SETTINGS/ACK/PING output back to the peer. +Existing credentials and fragmented memory-BIO transport fixtures are reused. +The test peer disables certificate verification, as those existing fixtures do; +this is a private protocol composition proof, not public listener or PKIX proof. + +There are 28 committed binary RFC 9113 transcripts. The shared corpus loader is +unchanged; the HTTP/2 runner decodes its own typed verdicts and compares exact +consumed offsets, output octets, settings effects, stream/connection scope, +wire codes, EOF and sticky terminal behavior.

Fixtures are registered in EXTRA_DIST. + +Public listener admission, feature reporting and dispatch remain unchanged. +This task does not serve public HTTP/2 requests, collect HPACK blocks, implement +stream lifecycle, multiplexing, window accounting, fair scheduling or drain. +These responsibilities belong to subsequent tasks. + +## TDD observations + +Behavioral RED receipts in `/private/tmp`: + +- `task139-frame-red.log`: the initial parser stub failed preface consumption, + single-event boundaries, malformed/truncated magic and frame skipping. +- `task139-settings-red.log`: the initial connection stub failed server output, + peer SETTINGS effects, FIFO ACK and deadlines. +- `task139-connection-red.log`: exact-budget segmented DATA header admission, + continuation EOF, initial reserve refusal and terminal accounting failed. +- `task139-stream-red.log`: malformed stream-frame floods bypassed the turn cap; + a stream error in priority-bearing HEADERS lost continuation ordering. +- `task139-output-red.log`: failure after partial control output lost the + in-progress frame before GOAWAY. +- `task139-local-settings-red.log`: omitted advisory fields incorrectly reset + the committed local snapshot. +- `task139-tls-red.log`: successful real handshakes still returned unknown + ALPN (six session checks and the adapter h2 gate; seven failures). + +All corresponding final tests pass.

URI schemes use URI syntax rather than an http/https-only whitelist. +These rules follow [RFC 9113 section 8](https://www.rfc-editor.org/rfc/rfc9113.html#section-8). + +Each accepted stream owns the head, sink, exchange, reservations and route task. +The connection-owner executor serializes handler resumptions with engine calls. +Stream 1 can suspend while stream 3 finishes.

The optimized bounded probe feeds 5,000/10,000/20,000 malformed heads; +each stops at the default 128-item limit with only the 4,096-byte connection +control reserve remaining. Its original-engine run took 17.561/46.585/152.277 ms, +while the repaired run took 0.992/0.851/0.756 ms. Timing is descriptive; the +configured item limit, terminal code and cleanup assertions are the gate. + +Response reservations now include retained semantic strings/vector storage, +HPACK encoded-string growth and primitive intermediates, and framed output. +The field vector is pre-sized, while active output reserves only its framed-wire +bound. The aggregate peak reservation lasts until output storage is freed; +refused/failed encodings free semantic and output storage before releasing it. +A 60,000-byte field is refused under a 150,000-byte child response budget before +unadmitted copying/encoding. The allocation probe uses a 500,000-byte child +budget and measures actual live allocations using macOS `malloc_size`: + +- Original engine: reservation 124,326 bytes, retained semantic allocations + 69,792 bytes, encoding peak additional 262,144 bytes; probe exits 3. +- Repaired engine: equal parent/child reservation 425,475 bytes, retained + semantic allocations 69,792 bytes, encoding peak additional 196,608 bytes. + Combined peak 266,400 bytes fits admission; wire output is 60,050 bytes. + The probe exits 0 and verifies only the connection control reserve remains + after output advancement. Allocator rounding is included in these figures. + +Reset regressions decode exact stream destinations and four-byte error codes +for semantic/priority errors, stream/body/CONNECT refusal, unsupported response +bodies and invalid response lengths. Valid siblings still respond. The reported +`reset(3, internal_error)` mutation produces 46 failed checks in the strengthened +header suite. Peer RST regressions cancel a parked handler before a late resume, +release stream/head reservations, remove a queued response and preserve a +sibling's completion. The wire oracle now rejects trailing fragments, unfinished +blocks, nested HEADERS and orphan CONTINUATION, with explicit negative cases. + +Groundwork TDD RED receipts: `/private/tmp/task140-fixer-headers-red.log` (four +oracle failures), `task140-fixer-exchange-red.log` (authority, pending-bound and +peak-budget failures), and `task140-fixer-allocation-red-exact.log` (allocation +assertion exit 3). The repaired focused TLS-off suites pass 22 tests / 2,587 +checks; TLS-on adds the real TLS boundary suite for 25 tests / 2,772 checks. +Focused ASan/UBSan passes the same 22 engine tests / 2,587 checks without a +diagnostic.

Bodyless `respond()` ends +HEADERS; `start_response()` leaves HEADERS open, with terminal DATA or trailers +coming from `finish()`. Existing sinks receive the streaming callback through +default delegation; the response_writer and exchange_decisions suites retain +one-head and terminal-decision coverage. + +DATA is debited by its full payload, including padding. Body octets produce no +receive credit until `pull()` copies them; processed padding and discarded +reset-stream bytes are reclaimed at connection scope. Consumption is coalesced +in counters. Queuing a WINDOW_UPDATE reserves a control slot but does not +increase receive allowance. Its first output exposure publishes the allowance, +matching the connection's existing borrowed-output commit boundary. Published +slots remain immutable across partial advancement. + +Initial SETTINGS advertises a zero stream receive window. The effective receive +window remains 65,535 until that SETTINGS is acknowledged, preserving legal +pre-ACK DATA. Each non-ended stream reserves a 65,535-byte receive ring plus +128 bytes before allocation; the connection allowance still bounds aggregate +unconsumed early DATA. Admission applies the smaller application cap (default +16,384, bounded to the configured engine cap). If already staged early data +exceeds that cap, the stream fails explicitly. After ACK, grants target admitted +free capacity and account for negative windows, unread bytes and queued grants. +A request larger than a two-byte policy buffer streams incrementally in tests. + +The engine reserves a reusable 16,384-byte parser payload buffer plus 128 bytes +before admission, so a granted DATA frame does not require a new shared-budget +reservation. SETTINGS, PING and WINDOW_UPDATE use fixed control scratch storage. +Stream metadata is charged before construction (`sizeof(stream) + 64`), with +stream-count, head-byte and head-field reservations. Header assembly, HPACK, +trailers and response representations retain their separate hierarchical +charges. Child refusal rolls reservations back; destruction tests assert zero +remaining stream/body/head/output usage. + +Response staging defaults to a fixed 16,384-byte ring plus 128 bytes. Both body +queue limits accept 1..65,535. An active DATA frame reserves its copied payload, +framed output and allocation allowance before allocating. Queue capacity is +freed when framed bytes retire; window credit is debited once when selecting a +frame. Partial advancement neither frees an unfinished frame nor double-debits +windows. One bounded DATA frame per eligible stream selection provides round +robin progress; controls take priority between frames. Open field blocks and +exposed DATA remain immutable through reset or connection failure. + +Request/response content-length uses checked unsigned decimal parsing with +consistent duplicates and actual body totals. Request trailers require terminal +HEADERS, reject pseudo/forbidden fields, retain repeated fields, and decode with +the same connection HPACK state. Response trailers encode after queued DATA in +transmission order. HEAD/304 metadata and body-forbidden statuses retain their +constraints. Empty terminal DATA is allowed without available window credit, +including a negative stream window after SETTINGS, per +[RFC 9113 section 6.9.1](https://www.rfc-editor.org/rfc/rfc9113.html#section-6.9.1). + +Completed handlers retain pending streaming output. An unfinished streaming +response resets on handler completion. Reset/failure disconnects the exchange, +wakes/detaches parked reads/writes, invalidates coroutine witnesses, removes +unexposed semantic output, refunds discarded connection credit, and preserves +already exposed wire storage.

The maximum +DATA staging reservation is `2 * 16,384 + 9 + 128 = 32,905` bytes. The fairness +storage case verifies that partial advancement retains that charge, retirement +releases exactly that reservation, and peer reset returns body/output usage to +the connection baseline. Stream count, head bytes and head fields return to zero; +after engine destruction, body/output reservations also return to zero. + +RST_STREAM on an idle odd client stream or any unsupported even server stream +terminates with connection PROTOCOL_ERROR.

Fixed-duration +windows refill on the first event at or after the interval. Adjacent boundaries +can permit twice the allowance in a short burst. Backward time cannot refill or +move the anchor; unsigned tick subtraction handles the entire signed clock range. +Pump turns, queue drains and output advancement never refill counters.

All six supported local tuples +fit the existing 45-byte control slot. Eligibility is captured when the first +frame-header octet arrives, survives fragmented HEADERS payloads and CONTINUATION, +and depends on the server advertisement, without requiring an ACK or client +capability setting. + +Extended CONNECT retains CONNECT as the semantic method and normalizes its +origin path through the existing path derivation. Pseudo-fields stay outside +ordinary semantic fields. Ordinary CONNECT and unsupported extended protocols +remain refused; malformed field sections reset only their stream while HPACK +context continues. The separate HTTP/2 handshake shares origin, version, +subprotocol and policy validation with HTTP/1, preserving HTTP/1 check order. +A successful response is status 200 without END_STREAM, optionally with the +selected subprotocol. It has no HTTP/1 Upgrade/Connection fields, accept hash, +content length or negotiated extensions. Keys are not required. Finite-body +metadata is refused before tunnel commitment, leaving ordinary refusal available. + +Each accepted stream owns a shared WebSocket driver and retains the normal HTTP/2 +receive ring, independent windows, scheduler and drain unit. Partial codec +consumption leaves the exact suffix in the ring; deferred completed messages get +zero-length retries after application receive progress. Masking, message limits, +Ping/Pong and Close handling come from the shared codec. Weak, coalesced progress +observers marshal work through the serialized owner and ignore retired streams. +Handlers may move sessions to application ownership and finish independently. + +Incoming windows debit full DATA payloads, including padding. Padding is reclaimed +immediately; tunnel octets are reclaimed when consumed from the receive ring. +Blocked codec admission stops new tunnel receive grants. The pre-ACK 65,535-byte +allowance is preserved. Outgoing DATA obeys both windows, peer frame size and the +16,384-byte scheduler quantum. Codec output is copied into one charged immutable +frame and consumed only as its payload retires; header writes consume no codec +bytes. Siblings and controls progress independently of blocked WebSockets. + +Codec limits are clamped against route limits, engine caps and available aggregate +budgets. Admission reserves conservative input, output, metadata/control and +message-assembly bounds before driver construction. Reservations are distinct +from receive-ring and active-frame charges. Output admission leaves headroom for +a separately charged DATA frame. Failed reservation releases provisional charges +and preserves ordinary refusal. Reset and destruction return stream reservations. + +Close bytes retire before an empty terminal DATA frame, which works without +positive credit. END_STREAM reaches the driver after retained input; missing +Close produces abnormal closure and stream CANCEL. Peer resets cancel pending +session operations once, remove semantic output/unexposed grants, preserve +borrowed frames and emit no echo. Connection EOF/destruction and deadline expiry +publish their transport reason before driver destruction.

The certificate matrix admits at most four active +peers; PSK uses the existing fixed two-worker handshake/lookup lanes, allowing a +new peer to authenticate while one old lookup is held. Abort guards release +callbacks on exceptional exits; socket owners close failed construction paths; +adapters close, real backends release connections, owners drain completions, +workers join and PSK runtimes stop/drain before callback captures are destroyed. +Every focused test invocation used a 180-second subprocess watchdog. + +ACME positives inject trusted internal `{tcp, 443}` listener metadata into the +adapter while the OS socket is actually bound to an ephemeral loopback port. +The negative TCP metadata row uses that actual ephemeral port.

The native core +contains the implementations; these codecs need no TLS provider. + +- `quic_codec.hpp` defines typed verdicts, checked cursors/writers and limits. +- `quic_varint.hpp` decodes general varints, supports explicitly wider writes, + writes truncated packet numbers, and reconstructs them using caller-supplied + largest-received context. It owns no packet-number-space state. +- `quic_packet.hpp` splits one envelope from a datagram. Initial, Handshake and + 0-RTT use their encoded lengths; short headers consume the remainder. Retry + and Version Negotiation have their own envelope shapes. Unsupported versions + have a separate verdict. 0-RTT recognition introduces no runtime acceptance. + Version Negotiation CIDs use the full 0–255-byte wire length; v1 long and + short headers retain the 20-byte CID limit. +- `quic_frame.hpp` yields one typed frame, with all core families and STREAM + flags. Placement follows the RFC frame table, including sender restrictions + and unidirectional stream direction. ACK ranges use a validated encoded view + and an allocation-free inclusive-range iterator. Outbound ACKs also accept + caller-provided typed ranges. +- `quic_transport_parameters.hpp` returns fixed typed values and defaults, + rejects duplicate IDs (including unknown IDs and alternate integer widths), + skips well-formed unknown values and checks known shapes/sender restrictions. + +Packet, token, CID, range, data and reason views borrow the original input. +Keep input alive and stable while using a result or iterator. No decoder copies +payloads or creates attacker-sized collections. Decoder errors consume zero +bytes and preserve external cursors. Results are committed after complete +syntax validation; failed parameter parses return default values, without +partially populated fields. + +Writers first validate and measure, then write to caller-provided storage. +Insufficient output or invalid values leave output unchanged. Input views must +remain stable across both passes and must not alias output. Successful writes +report their exact size through `consumed` and `value`. + +Default limits are 65,535 input bytes, 4,096 frame iterations, 256 parameters +and 256 additional ACK ranges. Parameter duplicate tracking has an absolute +256-entry stack bound even when a caller requests a larger limit. Frame and +ACK work bounds are caller-configurable and also constrained by input length. +Padding runs are returned together; scanning remains bounded by the byte limit. +A count/input policy failure is distinct from malformed syntax or truncation. + +## Protection and handshake boundary + +Envelope parsing identifies immutable fields and opaque protected bytes. It +never infers packet-number length, reserved bits or key phase from ciphertext. +`decode_quic_unprotected_header` takes the externally unmasked first byte and +packet-number bytes and reconstructs the number. It checks that unmasking did +not change immutable header bits. `validate_quic_authenticated_header` supplies +its reserved-bit verdict only for use **after successful authentication**. + +Packet writers take opaque payload/tag bytes; Retry integrity tags come from +the caller. They perform no cryptography. Datagram admission, Initial datagram +size enforcement, handshake/recovery/flow state and HTTP/3 journeys remain +outside these codecs. Frame decoding expects an authenticated clear payload. + +Transport-parameter shape parsing preserves CID presence, including an empty +CID. `validate_quic_transport_parameters` separately checks required initial +and original CIDs, Retry presence and supplied handshake CID values. Callers +must supply the actual authenticated handshake context before accepting the +parameters. Shape parsing alone does not authenticate CIDs. + +The codec contracts follow [RFC 9000 sections 16–19 and Appendix A](https://www.rfc-editor.org/rfc/rfc9000.html#section-16), +with the protection boundary from [RFC 9001 section 5.4](https://www.rfc-editor.org/rfc/rfc9001.html#section-5.4). + +## Behavioral RED/GREEN evidence + +Each codec slice first compiled against declarations and failure stubs, then +ran fixed-vector tests before its implementation was added. The initial runtime +RED receipts were 103 failed varint checks, two failed packet assertions, +34 failed frame checks, 13 failed parameter checks and three failed codec-fuzz +integration checks. The preferred-address fixture was corrected to the RFC's +24 address/port bytes before final GREEN verification. + +Direct slice commands used Apple Clang and real codec translation units: + +```sh +clang++ -std=c++20 -DHTTPSERVER_COMPILATION -Isrc -Itest \ + test/unit/quic_varint_test.cpp src/detail/quic_varint.cpp \ + -o build/quic-varint-red +build/quic-varint-red +``` + +The same pattern was used for packet, frame and parameter suites. GREEN +compiles added `-Wall -Wextra -Werror -pedantic` and each slice's real sources. +Frame serialization is in a separate translation unit to keep the reader and +writer small. An additional ACK-iterator regression first failed its third pair-consumption +assertion (four bytes instead of two), then passed after reporting each call's +consumption separately. The first range comes from the prefix, so its call +advances the iterator index while consuming zero encoded-range bytes. + +The fuzz integration RED/GREEN used the registered +`quic_fuzz_replay` executable linked against the native core. + +Fixed expected bytes cover RFC integer examples and transition octets, +all four packet-number widths, every supported packet envelope, every core +frame type and all eight STREAM flag combinations. Assertions also verify +expected typed fields, exact consumption, truncated prefixes, checked ACK +arithmetic, offset/length bounds, nonminimal frame-type rejection, CID/token/path +shapes, packet placement, parameter defaults/restrictions, alternate-width +known/unknown duplicates, the 256-parameter boundary and handshake CID checks. +Round trips supplement these independent expected-byte vectors. + +## Final local verification + +The task-local Autotools build uses Apple Clang 21.0.0, C++20, TLS off, +`CPPFLAGS=-I/opt/homebrew/include`, `LDFLAGS=-L/opt/homebrew/lib` and +`CXXFLAGS='-O0 -g'`. Existing legacy dependencies are discovered from Homebrew; +the new tests link only the native archive. + +The planned `--enable-debug` configuration encountered a pre-existing +`DEBUG` macro redefinition under `-Werror`.

Final logs are under `build/task151-codecs/`. + +The dedicated allocation executable prepares fixtures and test state before +its scope, intercepts ordinary/array/aligned/nothrow allocation entry points, +and aborts if any codec allocates within the scope. A separate self-test proves +the counter observes ordinary and aligned calls. Valid packet/header/frame/ +parameter reads and writes, borrowed 65,500-byte STREAM/CRYPTO data, huge packet +and frame lengths, huge ACK counts and duplicate/huge transport tuples all +complete with zero scoped allocations. + +The bounded fuzz target independently invokes scalar, envelope, frame and +parameter parsers on each raw input.

These results establish local codec behavior; +there is no interoperability, HTTP/3 request, deployment or production claim. + +## Validation repair, iteration 1 + +The authorized repair applies packet-specific CID bounds and strengthens the +independent field/value oracles. VN vectors with 21-byte and 255-byte destination +and source CIDs first produced 12 failing checks in +`build/validation-packet-red.log`; the repaired packet suite now passes 956 +checks. Truncated VN CIDs return transactional errors, VN writes reject 256-byte +CIDs without changing output, and v1 packets still reject oversized CIDs. + +All envelope-kind fixtures now assert CID values and borrowed locations, +including Initial source byte `0xef`, and applicable token, version-list, +integrity-tag and protected-remainder views. Client and server parameter +fixtures assert independent canonical bytes and every known numeric/CID/token +value after reparse. The bounded fuzz parameter round trip additionally preserves +known values, including preferred-address values, while allowing unknown tuples +and nonminimal widths to canonicalize. Existing fuzz caps are unchanged. + +Copied-source mutation probes confirm the assertions detect the reported gaps: +forcing parameter ID 4 (`initial_max_data`) to zero fails six checks, and +redirecting Initial source to destination bytes fails eight checks. Logs are +`build/validation-{parameters,packet}-mutant.log`; production sources were not +mutated for these probes. + +The core and nine focused test executables were rebuilt with the commands +above. The exact focused `make check` gate passed all nine executables, 45 cases +and 2,771 checks, with no skips (`build/validation-focused.log`). The sandboxed +run failed the existing UDP loopback assertion; the same command passed when +rerun with local socket access.

HKDF uses +OpenSSL 3.5 EVP_KDF extract/expand modes and TLS 1.3 labels. Initial protection +uses the fixed v1 salt, SHA-256 and AES-128-GCM. Traffic protection supports +AES-128-GCM/SHA-256, AES-256-GCM/SHA-384 and ChaCha20-Poly1305/SHA-256. +No installed header contains OpenSSL types or these interfaces. TLS-off builds +omit the new implementation and test executables. + +`quic_crypto.hpp` exposes move-only owned material, transactional derivation, +nonce and header-mask helpers, packet protection/opening, and Retry integrity. +Packet wrappers reject incompatible levels, 0-RTT, caller-supplied tags, overlap, +and malformed or insufficient buffers. Retry and Version Negotiation are outside +packet AEAD protection; Retry has its own integrity functions. + +Packets use the existing length-delimited envelope. Header samples stay inside +that packet, even in a coalesced datagram. Packet numbers XOR the full 62-bit +number into a 12-byte IV; truncated on-wire numbers serve only header encoding. +AES header protection uses ECB without padding. ChaCha header protection passes +the complete 16-byte sample into EVP's raw IV without changing its state words. +Retry authenticates separate length/CID/header AAD segments without a packet-sized +allocation. Verification authenticates the received tag with EVP. + +All packet input views, output, and scratch must be disjoint. The caller supplies +padding and the short-header CID length. Scratch holds at most 65,535 packet bytes; +protection clears its bounded scratch region and opening clears the packet region +used. Output stays unchanged on errors, including authentication, reserved-bit, +and authenticated key-transition failures. Tentative plaintext exists only in +scratch until all checks pass. EVP objects use RAII; owned secrets use existing +`secure_bytes`; temporary secret, nonce and mask arrays use `secure_zero`. + +## Connection-owned lifecycle + +`quic_key_state` is serialized on its owner thread. It owns directional Initial, +Handshake and application keys, one next write generation, and bounded +current/next/previous read generations plus one fixed dummy read key. Initial replacement and Handshake +replacement are transactional. Application installation is one-time per direction; +discarded levels cannot be reinstalled. A cleared owner cannot resurrect keys. + +The caller supplies handshake-completion/confirmation and generation-ACK facts. +The owner checks monotonic successful write packet numbers but does not allocate +them. Initial replacement retains this boundary. Write updates retire old material +immediately, toggle the phase, derive `quic ku`, and retain the directional HP key. +Read promotion requires successful authentication. Selection uses authenticated +current-generation packet-number boundaries; key-transition error reporting also +waits for authentication, before publishing plaintext. Authenticated reordered +previous-generation packets advance the previous maximum, so later current +packets cannot cross that boundary. + +Application read installation transactionally prepares random dummy AEAD key/IV +material with OpenSSL private randomness and retains the real directional HP key. +An unavailable previous or next generation performs the same bounded packet +authentication path with this material and returns `authentication_failed`; even +successful dummy authentication is rejected before plaintext publication or +promotion. No random material or generation is allocated/derived per rejected +packet. The dummy key is cleansed on application discard/owner clear. Provider +failures and caller buffer/format errors retain their existing codes. + +After a peer read update, sending is blocked until `respond_to_peer_update` +advances write keys to that generation. The transport must call this before +acknowledging the triggering packet. It explicitly retires previous read keys +and prepares the next read generation according to its PTO/recovery policy. +This module has no sockets, timers, SSL sessions, recovery engine, CRYPTO streams, +admission-token policy, or transport scheduling. + +Per-generation encryption limits are capped at 2^23 for AES-GCM and at the QUIC +packet-number ceiling for ChaCha20-Poly1305. Authentication failures accumulate +across all keys and generations, with caps of 2^52 for AES-GCM and 2^36 for +ChaCha20-Poly1305. Policy options can reduce these caps. Limits stop processing +before counters can overflow; application confidentiality exhaustion returns +`update_required`. Generation counters also reject arithmetic wraparound. + +## Fixed fixtures and development evidence + +[RFC 9001 Appendix A](https://www.rfc-editor.org/rfc/rfc9001.html#appendix-A) +provides exact client/server secrets, keys, IVs, HP keys, complete Initial packets, +Retry bytes, and the ChaCha packet/mask/next-secret assertions. The complete client +payload is padded to the published 1,162 bytes; wire comparison covers all 1,200 +protected packet bytes. Both directional Initial packets open and protect exactly. + +Additional pinned AES-256/SHA-384 fixtures use the secret bytes 00 through 2f, +packet number `0102030405060708`, CID `abcd`, and plaintext `01020304`. +They were generated independently with Python `hmac`/SHA-384 and cryptography +50.0.2 AESGCM/ECB, including a correctly authenticated reserved-bit violation. +Production uses OpenSSL 3.5.9, not that independent fixture generator. + +Development followed assertion-level RED/GREEN slices: + +- Derivation failure stubs: 2 failing assertions, then 21 passing checks. +- Packet/nonce/mask/Retry failure stubs: 11 failures, then 62 passing checks. +- Lifecycle failure stubs: 3 failing assertions, then 57 passing checks. +- Missing peer-response send gate: 2 failures, then the gate passed. +- Unauthenticated packet-number transition error: 1 failure, then authenticated + validation passed while preserving output. +- Incorrect Initial cipher acceptance: 1 failure, then fixed-v1-suite rejection + passed. + +The crypto executable has 9 tests / 180 checks; lifecycle now has 10 tests / +221 checks after the focused validation repair. The reordered-generation +regression first failed three checks, then passed after authenticated boundary +recording was repaired. Missing previous/next generation regressions first +failed six checks, then passed after dummy authentication was introduced. +Coverage includes unavailable slots for all three suites, deterministic rejection +of successfully authenticated plaintext, provider failures, installed-key +usability after installation failure, and cleansing.

The caller +owns stream materialization, retirement, and the rule against recreating retired +IDs; the counters are not a closed-stream registry or a stream-count limit. + +Bidirectional send and receive halves evolve independently; a unidirectional +stream makes its other half unavailable. Receive states distinguish receiving, +size known, all data received, data consumed, reset received, and reset consumed. +FIN is committed with accepted storage, so gaps and unread bytes delay EOF. +RESET_STREAM fixes final size, interrupts unread data, and releases all receive +storage without allocating missing data. Late STREAM frames still undergo +final-size validation and update the highest accepted end, but never refill a +reset receive half. Final-size checks remain active in terminal states. + +`take_terminal()` delivers EOF or the first reset error once. A reset may +replace a pending EOF, but cannot create another application terminal after +one was delivered. Repeated matching controls are idempotent. STOP_SENDING +creates one reset request with the first error and the highest sent end, even +after FIN was sent; it is ignored after all stream data was acknowledged. +Taking the request is distinct from `record_reset_sent()`. Reset retransmission +and packet/ACK tracking belong to the caller. ACK methods accept explicit facts +and do not implement recovery. Matching retransmissions preserve terminal send +states. No packet scheduling, CONNECTION_CLOSE, callbacks, flow control, CRYPTO, +TLS, or HTTP/3 engine integration is added here. + +## Bounds and error policy + +Accepted STREAM payload is copied before returning.

Actual retained payload capacity + is capped at the same value. A partial read retains the original allocation + and charge until replacement or complete consumption; consequently a sparse + insertion can hit the capacity bound before the unread-byte bound. +- `max_ranges` caps normalized retained intervals and descriptor capacity. + The fixed descriptor pool is allocated lazily on the first nonempty admission. + It remains charged after complete reads and is released on reset, `clear()` or + destruction. Allocation uses `allocator` to request exactly + `max_ranges * sizeof(range)` bytes, avoiding a hidden `new[]` destructor cookie. +- `max_offset_span` caps each accepted STREAM end relative to the consumed + offset. Large absolute offsets never size an allocation. RESET final size + does not allocate data or need to fit this receive-storage span. + +Both descriptor and payload allocation requests reserve +`server::resource::quic_reassembly_bytes` through the supplied budget and every +ancestor before allocation. Merges stage only affected ranges. Retained payload +never exceeds the payload limit, and old-plus-staged payload never exceeds twice +that limit; metadata has one explicitly bounded pool. Allocator bookkeeping +outside requested object storage is not part of the resource counter. Checked +configuration arithmetic ensures the maximum storage sum fits `size_t`; +invalid construction limits or unopened IDs throw `invalid_argument`. + +Every rejected insertion preserves payload, offsets, final size, states, and +budget usage. Allocation failure or hierarchical budget refusal returns +`no_memory`. Payload capacity returns `byte_limit_exceeded`; range/span limits +return `gap_limit_exceeded`. Protocol-facing results distinguish invalid +62-bit arithmetic (`frame_encoding_error`), invalid ID/direction +(`stream_state_error`), inconsistent final size (`final_size_error`), and +conflicting retained overlap (`protocol_violation`). The caller decides how +these results affect the connection; local storage limits do not masquerade +as peer protocol errors. + +## Executed local verification + +Task-local receipts are in ignored `build/task154/` and +`build/task154-autotools/test/`.

Callers use `delivered_prefix` for partial +contiguous CRYPTO delivery, and `take_completion` for stream/reset completion. +They explicitly cancel superseded segments, including STREAM information +superseded by a RESET_STREAM. Consumed completions and cancelled handles may +be reclaimed on the next retention admission; callers retain their own stream +or TLS delivery ledger beyond that point. + +`prepare_packet` selects a bounded pending slice, splitting payloads to fit +output and setting FIN only on the final slice. A probe prefers unsent data, +then undelivered transmitted data, then PING. No preparation marks information +sent or delivered. One preparation is outstanding at a time. Record capacity +is reserved before encryption: protect with the returned packet number, then +`commit_sent` with the actual emission timestamp/wire length, or +`abandon_packet` on failure. All allocated packet numbers are burned, including +abandoned/short preparations, so an encryption nonce is never reused. +Successful commit performs no allocation. Prepared information may become +delivered or cancelled while waiting for emission without recreating pending +information on commit. The owner must supply valid monotonic timestamps, +apply send permission and current keys before emission, and abandon cancelled +transport preparations before discarding their packet-number space. + +Standalone `reserve_packet` supports caller-generated ACK/PING/control packets. +`commit_sent` validates its token, emission flags and length. Application key +generation acknowledgements are returned as facts to the caller's key owner. +Decoded ACK ranges are fully validated before any delivery/RTT/accounting +mutation. Unsent numbers detectable above the retired sent floor are rejected; +repeated ACKs and old ranges below that floor produce no duplicate events. + +RTT samples require a newly acknowledged largest packet and at least one newly +acknowledged ack-eliciting packet. The minimum is unadjusted. The first sample +initializes the estimator, including a sample taken at time zero. Initial and +Handshake ignore ACK delay; before handshake confirmation Application also +ignores delay. Confirmed Application delay is capped before shifting, avoiding +integer overflow. Subsequent estimates use 1/4 RTT variance and 1/8 smoothed RTT +updates. Loss uses packet threshold 3 and time threshold +`max(9/8 * max(latest, smoothed), 1ms)`, only in the acknowledged space. + +Call `set_environment` when key availability, handshake confirmation, send +permission or peer validation changes. In particular clients supply their +initial peer-validation fact and time to arm the anti-deadlock timer. Local +amplification permission is distinct from whether the peer validated this +endpoint. Servers implicitly regard peer validation as complete; a Handshake +ACK also establishes it. `next_deadline` coordinates ACK work with recovery. +A loss deadline takes priority over PTO and remains active when sending is +blocked. Application PTO is ineligible before confirmation. PTO initially uses +333ms RTT and 166.5ms variance (999ms timeout); confirmed Application adds peer +maximum ACK delay. Backoff doubles and saturates safely. `expire` reports due +ACK spaces, loss bytes, or one/two probe requests without declaring PTO packets +lost. Late expiry rearming uses the expiry time to avoid repeated immediate +probe requests. Any newly acknowledged packet resets backoff once the peer +has validated this endpoint, including ACK-only and PADDING packets. This +reset is independent of RTT sampling; duplicate ACKs and unvalidated-client +Initial ACKs preserve backoff. A new Handshake ACK establishes peer validation. +Space discard reports discarded bytes separately from loss, cancels its +information/preparation/history and resets backoff. + +## Storage and future transport integration + +The existing hierarchical `quic_reassembly_bytes` budget charges the bounded +receive/sent/information descriptor tables at construction and twice each +retained payload length (owned bytes plus one delivery-status byte per byte). +No allocation depends on a packet number or stream offset. Limits also bound +sent records, information handles and total retained payload. Failed budget +admissions roll back their reservations. Invalid configuration throws; +allocation/budget failure for the tables leaves a refused owner returning +`no_memory`. Payload admissions return typed `capacity`/`no_memory` results. +Live lost aliases are never evicted to admit replacements: exhaustion applies +backpressure until delivery/cancellation frees them. Receive history and fully +retired sent prefixes can be reclaimed within their explicit floors. + +Backend timer registration and its `timers` budget remain with the future +transport scheduler. The caller composes `quic_key_state::protect_packet` and +`open_packet`, TLS `copy_output`/`retire_output_prefix`, and stream sent/ACK +state transitions with this owner's facts. Wire byte events account only +packets still in flight; late ACKs of lost packets deliver information without +counting their bytes twice. No congestion policy is implemented here. + +## Reproduction + +The exact existing worktree/branch were verified as `task/TASK-156`, based on +`v3` at `66f6fb32c1502b86f7b7b1e0f7b5a8d045aab550`.

It does not add an HTTP/3 parser, application +exchange, congestion controller, pacer, or UDP connection engine. + +## Owner and wire invariants + +A serialized connection owner keeps one `quic_flow_control`. It copies initial +numeric limits from validated local and peer transport parameters. The four +stream classes use the advertiser's perspective for asymmetric bidirectional +limits: a locally initiated stream sends against peer bidi-remote credit and +receives against local bidi-local credit. Unidirectional send/receive eligibility +continues to use the existing stream state and frame direction rules. + +Local stream-count exhaustion returns `blocked`. A peer's excessive ordinal +returns `stream_limit_error` before high-water counters or descriptors change. +A sparse higher peer ID opens implicit lower IDs without materializing their +stream objects. Numeric records are charged and reserved before allocation; +there are at most `max_records` records (hard configuration ceiling 65536). +They retain closed-stream facts for the whole connection and are never evicted. +The owner must keep each materialized stream object stable through retirement, +and must never recreate a retired ID. Capacity exhaustion returns a local +`capacity` refusal, rather than misclassifying it as a peer violation. + +Accepted receive credit counts each stream's highest offset, including FIN and +RESET final size; the connection counts the sum of increases. Duplicates, gaps, +and overlap therefore never charge a previously accepted extent twice. Checks +precede stream storage admission, and the ledger commits only after stream +validation and reassembly succeed. Conflicting overlap, invalid final size, +allocation refusal, and storage/budget limits leave byte counters unchanged. +Stream state remains the authority for final-size consistency and directions. + +Incoming MAX values increase absolute send limits; smaller/equal values do +nothing. MAX_STREAM_DATA validates direction and creation/count state. BLOCKED +frames never replenish credit and cannot grow unbounded records. Arithmetic is +checked at the 62-bit QUIC integer ceiling; receive-window growth saturates +there. The wire contracts follow RFC 9000 sections 4, 4.5, 19.9–19.14. + +## Semantic retirement + +`quic_stream_state::read()` extracts raw transport bytes into a parser or body +staging area. It releases reassembly storage, but does **not** release QUIC byte +credit. The same unreleased transport extent still bounds staged body data. +The future HTTP/3 adapter must budget its staging allocations as well. + +`consume_body(stream, through_offset)` reports ordered transport offsets whose +associated body content has actually been consumed by the application. +`consume_protocol` retires protocol-only bytes using that same release cursor. +Neither receipt may cross earlier unconsumed body content. The adapter supplies +this semantic fact; the numeric ledger cannot infer it from parsing. Receipts +must be between the previous release cursor and the extracted offset. Equal +receipts release zero; backward or unextracted offsets return +`invalid_consumption`. Both connection and stream targets advance exactly once. +A stalled body retains its original window while an independently consumed body +can advance its own stream credit and the connection's shared credit. + +RESET first accounts final size and discards receive storage. `settle_reset` +then retires abandoned credit once at connection scope, stops stream-credit +updates, and preserves the opposite send half. STOP_SENDING does not retire +receive credit. Count replenishment requires terminal retirement of all +applicable halves; bidirectional receive consumption alone is insufficient. +New stream-count credit stops when the descriptor table has no remaining room +for additional retained facts. Retirement does not reclaim those facts. + +## Recovery composition + +The constrained `prepare_packet(..., flow)` overload skips blocked STREAM work, +splits payload to available byte credit, validates RESET against the highest +committed send extent, and continues selecting critical work. FIN bounds later +eligibility. `quic_send_plan` exposes the selected STREAM, RESET, or flow-control +snapshot. Preparation and failed/abandoned emission charge no committed send +credit. `commit_sent` charges exactly the selected extent without allocation; +loss or probes of previously emitted extents charge zero. The flow owner must +outlive an outstanding preparation, and the connection owner must not mutate its +send ledger independently between preparation and emission/commit. The legacy +unconstrained overload remains available for existing standalone recovery users. + +`retain_flow` retains only MAX_DATA, MAX_STREAM_DATA and the two MAX_STREAMS +classes. Controls carry owned numeric snapshots. Supersession reuses a bounded +descriptor with a fresh information ID, so loss and late ACKs of old packets +cannot restore an old value or acknowledge a newer generation. Completed MAX +facts remain bounded and retained, preserving monotonic coalescing across other +admission. STREAM cancellation and space discard release copied payload/status +storage once. ACK history for collected critical packets uses preallocated, +coalesced ranges; it distinguishes committed packet numbers from abandoned +numbers while freeing critical records behind stalled ordinary packets. + +The semantic owner queries `pending_credit()` or a named +`pending_credit(kind, stream_id)` to obtain outstanding targets independently. +It passes each target to `retain_flow`, calls `credit_emitted(plan.flow)` only +after successful packet emission, and calls `credit_acknowledged` with the flow +snapshot from `take_completion()` after recovery reports delivery. Desired, +emitted and acknowledged values are separate monotonic facts. Abandoned output +and dropped packets retain reliable work in recovery. Consumption queues credit +without waiting for a BLOCKED frame. RESET/retirement should cancel any retained +stream MAX information that is no longer useful. + +## Protected storage arithmetic + +Recovery configuration reserves explicit `critical_information`, +`critical_retained_bytes`, and `critical_sent_packets` within existing total +quotas. Each must fit its corresponding total. Ordinary STREAM admission cannot +spend these quotas. CRYPTO, MAX, and RESET information has selection priority; +ACK-only packets use critical records and are selected ahead of pending STREAM +payload when ACK work exists. Data proceeds when eligible critical work drains. +Default zero reservations preserve the older standalone API; a composed owner +must configure nonzero reservations for its required critical workload. + +Logical quotas alone do not protect shared ancestor memory. `quic_storage_pool` +reserves a connection envelope against the supplied budget and every ancestor +before accepting storage owners. Its independent, bounded data/critical roots +subdivide that already charged envelope, avoiding double charges at original +ancestors. The sum must fit the existing resource ceiling. No public resource +keys or general budget API change. Pool construction reports invalid arithmetic +with `invalid_argument` and allocation/admission refusal with `bad_alloc`. + +A connection computes its envelope using the actual storage helpers: + +```text +D = receive_stream_bound * quic_reassembly::storage_capacity(stream_limits) + + 2 * (recovery.max_retained_bytes - recovery.critical_retained_bytes) + + bounded parser/body staging storage +C = quic_flow_control::storage_capacity(max_records) + + quic_recovery::storage_capacity(recovery) + + 2 * recovery.critical_retained_bytes + + configured CRYPTO/TLS storage +``` + +Each reassembly helper includes its exact descriptor table and twice the maximum +payload, covering old-plus-staged merges. Recovery metadata includes every +space's receive ranges, packet records, collected-critical-packet ranges, and +information descriptors. The factor two for retained recovery payload accounts +for owned bytes and per-byte delivery status. QUIC TLS storage is three input +reassembly envelopes, three configured output capacities, receive-lease capacity, +maximum peer parameters, and copied local parameters; the TLS callback storage +helper calculates and validates this sum. Caller sums/products must be checked +before constructing the pool. Storage-owner objects, allocator bookkeeping, +provider-internal TLS allocations, and fixed key objects are outside these +existing requested-buffer accounting quotas. + +Pass `pool.data()` leases to receive STREAM storage and the recovery data side; +pass `pool.critical()` to the flow ledger, recovery critical side and CRYPTO/TLS +owners. Leases retain the ancestor reservation until the last covered owner and +all its buffers are destroyed, even when the pool handle goes away first. Always +pass the lease to a covered owner, not a detached copy of its internal budget. +Direct-budget constructors retain their older ancestor-charging behavior and +must not be mixed with detached internal pool budgets. Envelope configuration +can refuse undersized storage locally; it never spills data into critical roots. + +## Local evidence + +Ignored `build/task157/` contains RED/GREEN and sanitizer receipts. The baseline +stream suite passed before implementation. Failure stubs produced 5 failed +flow-ledger checks and 5 failed recovery checks. Protected-storage stubs produced +8 failures. Subsequent RED cases caught lost MAX history, ACK starvation, +recreated stream retirement, post-FIN send eligibility, invalid RESET selection, +and missing independent credit snapshots. TLS callback and session lifetime +oracles each caught a prematurely released ancestor envelope before correction. + +Final C++20 strict standalone suites pass: flow ledger 8 cases / 167 checks, +flow/recovery composition 9 cases / 235 checks, protected storage 4 cases / +51 checks, and TLS callback/storage 8 cases / 204 checks. All four pass again +with AddressSanitizer and UndefinedBehaviorSanitizer and no diagnostics. The +reused OpenSSL provider is not sanitizer instrumented. + +Autotools TLS-on builds the C++20 v3core and passes all 13 focused executables, +including the affected codecs, reassembly/state, ACK/recovery/repacketization, +real independent-client TLS handshake, and genuine outbound-CRYPTO recovery +seam. TLS-off builds provider-free v3core and passes all 10 focused executables. +The new independent-client TLS handshake also completes while the data budget is +fully reserved, and its protected ancestor reservation outlives the pool handle. +The composition suite bounds stalled body A while body B extracts and consumes +partially, then admits additional credited data.

The task remains **In Progress** +for caller-owned validation and finalization. No commit, merge, or worktree +cleanup was performed by the executor. + +## Owner and transport contract + +`quic_recovery` owns the sent ledger and authoritative wire bytes in flight. +NewReno and pacing are allocation-free values in its private implementation; +all three packet-number spaces share their state. Emission time must be +nondecreasing across spaces. Invalid and duplicate ACKs cannot repeat growth, +and late ACKs of lost packets do not restore flight accounting or grow the +window. Discarding keys removes flight bytes without treating them as loss. +Peer ECN counters are not used as validated congestion feedback. + +The future serialized connection owner must use `prepare_scheduled_packet`, +provide actual packet protection/padding overhead, protect the reserved packet +number, then call `check_scheduled_emission` immediately before emission with +its actual wire size and flags. With no intervening owner event, a successful +check admits that emission; `commit_sent` records it without allocation. Its +recheck catches violations of that owner contract. Flow final sizes, RESET +state, key availability, send permission, congestion and pacing are checked +before emission. A failed transport send must abandon the preparation. + +The original reserve/prepare interfaces remain low-level seams for recovery +and codec fixtures. They do not promise scheduled admission. Every committed +in-flight packet still contributes to congestion and pacing observations. +Preparation, encryption failure, invalid commit, and abandonment consume no +pacing tokens, flow credit, probe grant, or stream service turn. + +The result distinguishes `congestion_blocked`, `pacing_blocked` (with a +deadline), and `unavailable` from storage capacity, invalid input, no data, +and insufficient encoding space. `next_send_deadline` reports the most recent +pacing admission deadline; ACK/environment/discard events invalidate it and +must prompt another admission attempt. Delayed emission charges its actual +time, not preparation time. Backend timer ownership remains outside this core. + +## Configuration and bounded resources + +- Maximum datagram size defaults to 1200 wire bytes; supported configurations + are 1200 through 65535. The initial window is + `min(10*M, max(14720, 2*M))`; the minimum window is `2*M`. +- Slow start adds newly acknowledged eligible wire bytes. Avoidance accumulates + byte credit and increases by one datagram per acknowledged window, avoiding + integer multiplication overflow. A loss epoch halves once. Persistent loss + reduces to the minimum and preserves the slow-start threshold. +- Application/flow-limited scheduled emission suppresses growth when no eligible + stream work remains below the window, or when the caller explicitly marks + the request limited. Pacing blockage alone does not mark packets limited. +- Pacing uses a conservative rate of one window per smoothed RTT, a 1 ms RTT + floor, and a two-datagram burst cap. Idle time cannot accumulate more credit. + Non-flight ACK-only work bypasses it; padded ACK packets still charge it. +- Ordinary streams leave `min(control_reserve, window/2)` unused; the default + reserve is 1200 bytes. Thus one ordinary datagram can progress at the minimum + window. CRYPTO, reliable MAX/RESET, and ACK work retain protected storage and + descriptor admission and may use the full shared window. Reserve never + authorizes ordinary control to exceed the window. +- PTO expiry replaces a space's outstanding grant with at most the reported + one/two probes. Only successful scheduled eliciting emission consumes it. + Probes bypass window/pacing admission, remain in flight and charge the pacer, + and still require keys/send permission. ACK progress retires unused grants; + discard retires grants for that space. Probe expiry is not a loss event. + +Stream scheduling uses deficit round robin with a datagram-sized payload +quantum and at most one quantum of credit per stream. Retained segments of +one stream share one entry; sparse stream IDs buy no extra turns. Small +segments continue the same turn until its credit is consumed. Empty FIN +costs one service unit. Blocked/cancelled/completed streams are skipped; +retransmissions preserve information IDs and alias completion behavior. + +At most two emitted Application controls or ACK-only packets precede eligible +ordinary service. When storage, the ordinary window, or pacing blocks data, +protected ACK/control progress continues. ACKs can accompany the selected data +turn; insufficient frame output falls back to ACK-only preparation. With N +continuously eligible streams, at most `(N-1)*M` ordinary service units +precede a stream's next turn, with at most two control emissions between each +data emission. Selection is bounded by the configured retained descriptor +count. No HTTP/3 stream criticality is inferred from stream IDs. + +`storage_capacity()` charges one scheduling entry per possible information +record plus `3*max_sent_packets+1` congestion outcome summaries. Constructor +allocations are staged; failed admission rolls back them and the reservation. +Successful commit never grows these vectors. Outcome summaries carry no +flight-byte/retransmission ledger. They preserve sampled lost endpoints and +ACK separators across packet collection and spaces. Persistent congestion +uses the strict duration boundary +`3*(smoothed_rtt + max(4*rttvar, 1ms) + peer_max_ack_delay)`, including ACK +delay for every space, following [RFC 9002 section 7.6](https://www.rfc-editor.org/rfc/rfc9002.html#section-7.6). + +Adjacent resolved outcomes are compacted. A late ACK into a compressed lost +interval invalidates the whole interval conservatively. If summary capacity +is exhausted, only the oldest prefix is forgotten; this can delay detection +of a historical run but cannot create a false persistent-loss interval. +Repeated expiry without a new loss cannot collapse the window again. + +## Local implementation evidence + +No sleeps are used in QUIC tests. The new model suites contain 3 congestion +and 2 pacing tests; send scheduling contains 19 tests. The storage regression +also proves allocation-free scheduled commit and complete budget release. + +RED observations and subsequent GREEN runs are retained under ignored +`build/task158-off/`: missing model headers and scheduling API; missing +persistent-loss collapse; application/flow limitation and padded ACK pacing; +persistent-loss slow start; emission flow/time recheck; ACK-after-collection +separation; probe retirement and final wire-size deadline; continuously +replenished ACK fairness.

The TLS-on configuration reuses the existing, +unmodified provider at `/private/tmp/task129-provider/install`, configured +with `--enable-v3-tls`, its include directory and `-lssl -lcrypto`. Eight suites +cover congestion, pacing, scheduling, recovery-TLS, TLS session/handshake, +flow-storage, and flow-recovery. Each build has final `completed-*.log` receipts: TLS-off 13/13 programs, +TLS-on 8/8, and ASan/UBSan 7/7. TLS-off/on native linkage and TLS-off +`check-local` pass. An additional linkage audit of the instrumented build +rejects the injected ASan runtime (`libclang_rt.asan_osx_dynamic.dylib`) under +the existing third-party allowlist; no allowlist change was made. The ordinary +TLS-off/on builds supply the native linkage receipts. + +An overlapping TLS-off core archive link and staged-install build caused +transient missing-symbol errors. The generated task-local archive was rebuilt +and its complete build/test/linkage/check-local chain rerun sequentially; the +final receipts are green. The earlier diagnostics remain in ignored +`off-link-race.log` / `off-install-link-race.log`. + +Changed-file cpplint, CCN <= 10, warning-suppression checks, and diff whitespace +checks pass. Repository-wide complexity has 17 existing violations, and file +size has the existing `io_poll_backend.cpp` 509-SLOC violation.

BSD, Windows and other nonlocal checks remain +assigned to CI/the v3 PR. UDP/HTTP3 interoperability, amplification enforcement +at the transport, coalesced datagram sizing, PMTU, migration and ECN activation +remain future transport work; no such proof is claimed here. + +## Validation repair, iteration 1 + +The two authorized architecture findings are repaired. Scheduled fairness now +encodes the bounded STREAM candidate into the available frame output and checks +its encoded size plus protection overhead, rather than the request's maximum +wire allowance. The final scheduled emission check still admits the actual +protected/padded packet. An outstanding preparation returns `busy` before the +candidate encoder can alter its output. + +If an information packet is rejected by congestion or pacing while an ACK is +pending, preparation abandons that packet and retries protected ACK-only work. +The retained information remains pending, with no completion, flow charge, +probe consumption, or fairness turn from the abandoned preparation. ACK-only +plans still use the normal scheduled checks for keys, send permission and final +wire/padding admission. + +Four deterministic scheduling regressions reproduced the original window and +pacing failures before repair (`build/task158-off/repair-iter1-red-tests.log`). +A fifth regression reproduced output corruption from a busy retry while the +new candidate encoder was active, then passed after the early busy check +(`repair-iter1-busy-red-tests.log`). The repaired focused TLS-off scheduling +suite passes 24 tests / 365 checks (`repair-iter1-green-tests.log`). Changed-file +cpplint and production CCN <= 10 pass (`repair-iter1-cpplint.log` and +`repair-iter1-complexity.log`). The coordinator owns the final TLS-off/on, +sanitizer, linkage and check-local gate barrier; these repair receipts alone +do not claim that barrier was rerun. diff --git a/docs/task-160-http3-control-streams.md b/docs/task-160-http3-control-streams.md new file mode 100644 index 000000000..a692cdc59 --- /dev/null +++ b/docs/task-160-http3-control-streams.md @@ -0,0 +1,153 @@ +# TASK-160 HTTP/3 framing and control ownership + +The private, provider-free server connection core classifies admitted peer +QUIC IDs and incrementally classifies unidirectional types. It owns one peer +control stream and each QPACK critical role. The QUIC owner still opens IDs, +reassembles ordered bytes, drives serialized turns and delivers terminals. +There is no UDP listener or semantic exchange bridge in this change. + +The control stream requires SETTINGS first and publishes staged settings only +after complete validation. Duplicate IDs (including ignored IDs), HTTP/2 +reserved IDs, repeated SETTINGS, wrong frame roles and malformed scalar +payloads have separate connection error mappings. Requests accept defaults +before peer SETTINGS and enforce HEADERS, DATA*, optional trailing HEADERS. +Unknown stream types and frames are discarded without payload copies. +Client GOAWAY carries a push ID, so it has no request-stream-ID bit constraint. +Scalar push/drain frames receive role and exact payload-layout validation; +this slice does not implement push ownership or graceful drain semantics. +The transcript oracle follows [RFC 9114](https://www.rfc-editor.org/rfc/rfc9114.html). + +Static-only HEADERS use the connection-owned QPACK codec. Invalid compressed +sections map to 0x200, prohibited dynamic encoder instructions to 0x201, and +acknowledgments/increments without dynamic references to 0x202. Bounded Stream +Cancellation instructions and zero encoder capacity are accepted. Local owned +prefixes contain the control type plus exactly one SETTINGS advertising zero +QPACK capacity/blocked streams, and the two QPACK types. The owner binds opened +server unidirectional IDs; retries cannot bind a second ID to one role or rewind +partial output. No peer SETTINGS prerequisite delays these prefixes. +These stream rules follow [RFC 9204](https://www.rfc-editor.org/rfc/rfc9204.html). + +## Bounded ownership + +Defaults are 64 KiB compressed HEADERS, 64 KiB expanded field-section size, +256 fields, 4 KiB SETTINGS, 64 setting identifiers, 16 KiB DATA chunks, +64 completed frame/chunk events per serialized turn, and 128 retained stream +records. Exact HEADERS/SETTINGS bounds are admitted; excessive byte, field or +record loads fail with excessive load (0x107). DATA is chunked and exhausted turn +budgets yield until `begin_turn()`. Stream facts cannot be recreated after FIN/RESET. +Settings values retain all 62 wire bits and never increase local admission caps. + +HEADERS assembly and decoded descriptors/strings reserve data storage before +allocation. Control payloads, connection/settings scratch/output and stream +metadata reserve protected critical storage. Scalars use eight fixed bytes; +partial QUIC integers use at most eight bytes, and QPACK instructions at most +ten. Unknown payloads and borrowed DATA allocate no declared-length storage. +Configuration arithmetic, ordered offsets and narrowing are checked before use. +The QPACK decoder's additional private `decode_allocated` entry point preserves +its existing checked API while letting precharged owners map allocation failure +to internal error (0x102), independently from configured load refusal. +Failed admissions roll back reservations; leases retain the ancestor envelope +when the original pool handle is destroyed. + +Each request has one outstanding immutable event; its bytes/fields stay valid +until release. A stalled request does not prevent another stream or critical +control processing. DATA borrows caller input; the caller retains that span and +unconsumed input. Events expose absolute frame/payload boundaries. Releasing an +event releases storage/lifetime only. The composition fixture sends framing +receipts through `consume_protocol`, advances partial body receipts through +`consume_body`, and defers later framing credit until preceding DATA is handled. +RESET cancellation abandons parser storage and uses `settle_reset` for credit. +Known critical FIN/RESET takes error 0x104; ordinary clean truncation takes +0x106; request RESET mid-frame is cancellation. FIN/RESET before a complete +unidirectional type is tolerated: incomplete type scratch is discarded, the +closed stream record is retained, and unrelated requests/control remain usable. + +## Local verification + +Registered worktree: `.worktrees/TASK-160`, branch `task/TASK-160`, base `v3`, +initial HEAD `1f8c6a33`.

Initial +compilation failed on the missing private HTTP/3 header (`task160-red.log`). +Subsequent red regressions exposed allocator failure misclassification and +retained payload charge, scalar allocation, overflowing configured descriptor +arithmetic, local critical-terminal classification, allocation failure in a +quota-refusal diagnostic, and the erroneous client GOAWAY bit restriction. +Each reproduced failure is retained under the ignored task-local build receipts; +all are green in the final suites. + +The local build used `./bootstrap`, then an out-of-tree configuration with +`--disable-examples --disable-v3-tls`, Homebrew include/library paths and +`CXXFLAGS='-O1 -g'`.

The serialized connection owner +supplies these dependencies and keeps them alive through adapter destruction. +Connection identity and the available peer snapshot travel into each exchange. +There is no UDP listener, packet protection, TLS negotiation or public API change. + +Initial HEADERS dispatch without waiting for DATA or FIN. Pseudo-fields, ordinary +fields, Host/authority, targets, Content-Length and trailers use shared semantic +validation without passing HPACK types through the HTTP/3 adapter. HTTP/2 retains +its Extended CONNECT behavior; HTTP/3 rejects CONNECT and `:protocol` in this slice. +Malformed semantic messages request a stream RESET with H3_MESSAGE_ERROR (0x10e). +Compression, framing and critical-stream failures retain the framing core's +connection error scope. + +The body adapter reuses the existing fixed-capacity semantic rings. Their HTTP/2 +window members do not participate in QUIC accounting. Admission clamps to the +configured H3 cap. DATA stays borrowed by the framing core before application +admission, then the smaller application ring cap applies backpressure; bounded +scratch holds the event through partial copies. A fixed ordered receipt ledger records protocol extents and exact DATA +chunk extents. Application pulls alone advance body receipts, and protocol bytes +behind unread DATA remain uncredited. Trailers become visible only after a clean +QUIC FIN, successful parser completion and an application EOF observation. + +Reliable response retention copies bounded HEADERS/DATA/trailers prefixes and +returns writer capacity before ACK. Successful retention advances the response +cursor; refusal preserves the cursor, body capacity and FIN. The adapter never +records actual stream emission. The owner must prepare a scheduled packet, +recheck scheduled emission, emit or abandon it, record the transport stream's +actual sent offsets, and commit recovery's flow accounting. Completion callbacks +remove only adapter-owned information IDs; the adapter never drains the shared +recovery completion queue. Ordinary response retention rotates after successful admission, including under +a one-record cap. Local critical prefixes use three reserved adapter records +and carry explicit critical retention classification through recovery storage, +information/byte admission and control scheduling. They remain STREAM information +for flow accounting, ACK/loss replay and completions, and are forwarded without FIN. + +Owner actions expose STOP_SENDING and RESET_STREAM frames. RESET final size comes +from the QUIC stream's actual emitted high-water mark, never the response retention +cursor. Peer reset settlement is idempotent and releases only reset credit. A +committed response can abandon unread receive input with bounded storage and +STOP_SENDING; a peer RESET honoring that STOP preserves the valid response half. +Other peer resets, STOP_SENDING and connection failure invalidate handler frames +and cancel retained output. Clean request FIN leaves response production usable. +Stream facts remain bounded and prevent recreation of closed IDs. + +Semantic heads, scratch, receipt descriptors, handler/stream metadata, ring peaks, +response encoding and trailer copies are reserved before allocation against the +QUIC storage lease. Semantic resource counters additionally track heads and body +rings. Cancellation frees partial response allocations before releasing their +reservations. The shared `request_handler_frames` helper preserves executor +affinity, queued witnesses and destruction after the outermost resume returns, +including inline cancellation and destruction from a handler. + +## TDD evidence + +The initial head and composition suites were compiled before the private H3 +adapter existed.

This task does not enable the public HTTP/3 listener. + +## Bounds and ownership + +The advertised active CID limit is four. Local issuance respects the negotiated +peer limit (default two, clamped to four). Each direction has 32 cumulative CID +records, including sequence zero; exhausted history refuses further issuance +rather than forgetting IDs or reset tokens.

RNG, collision, listener or recovery-capacity failure +rolls back unpublished routes. Random collision searches stop after four +attempts. ACKs complete advertisements without retiring routes. RETIRE removes +a route; the enclosing destination CID and unissued sequences cannot retire. +A valid retirement attempts replacement issuance within the bounds. Retired +CID/token history remains owned so reuse is rejected. NEW_CONNECTION_ID and +RETIRE_CONNECTION_ID use the existing reliable information scheduler, including +fresh packet numbers on loss and exactly one completion on late ACKs. + +There are three path records: the active path and up to two other records. +Candidates and previous active paths expire within three validation intervals, +capped at fifteen seconds. Active and pending-send records cannot expire. +Challenges have at most three actual emissions. The timer interval is at least +one second and the current application PTO, including backoff. The previous +path gets a challenge on apparent migration; newer non-probing traffic can +supersede a candidate or restore a previously validated path. + +The critical storage lease charges the state plus conservative allowances of +2048 bytes per path budget and 256 bytes per CID route. Listener lookup and its +retired history retain their independent bounds. Alias sinks hold weak owner +references. Releasing the original registration and fixture references destroys +the connection, removes aliases, and releases its storage envelope. + +## Authorization, validation and input + +Candidate records follow authentication, freshness inspection and complete +frame decoding. Unknown, failed-authentication, duplicate and stale packets do +not select application output. A full candidate set drops the candidate while +preserving the active connection. Per-datagram credit is counted once across +coalesced packets; admitted Initial credit is not counted twice. + +Each candidate owns an independent amplification budget keyed by canonical +peer, local endpoint, scope, interface and socket. Controls reserve that budget +and pin the copied destination CID until actual completion. Proven-unsent +completion burns the packet number and refunds the reservation. Successful or +ambiguous emission keeps the debit. A submitted application emission likewise +pins identity; the owner drops arrivals while that completion is pending and +never acknowledges their dropped payload. + +PATH_RESPONSE echoes its challenge on the receive path and is one-shot after +actual emission. Validation controls pad to 1200 bytes when credit permits, +using the selected destination CID's width. An unpadded challenge can establish +reachability, but activation still waits for a subsequent padded validation. +Random challenge tokens bind only after actual emission. An expired, wrong or +proven-unsent token cannot validate. A matching response arriving on any path +validates the path on which the challenge was sent, not its arrival path. + +Activation requires the newest fresh non-probing application packet's selected +path, reachability, minimum-MTU validation and live policy acceptance. PATH-only +traffic cannot grant migration intent. Discovery and activation each classify +against the actual runtime `server::peer_policy`; port-only rebinding also +reevaluates policy.

The unchanged incoming CID +and unchanged local endpoint/socket/interface permit NAT rebinding's reuse +exception. Retiring a candidate's peer CID discards that candidate and its old +validation token rather than reusing the active CID on another local endpoint. + +These choices follow [RFC 9000 §§5.1 and 19.15–19.16](https://www.rfc-editor.org/rfc/rfc9000.html#section-5.1), +[§8.2](https://www.rfc-editor.org/rfc/rfc9000.html#section-8.2), and +[§9.3–9.5](https://www.rfc-editor.org/rfc/rfc9000.html#section-9.3). +General PMTU discovery, draining, reset packet generation and preferred-address +migration remain later tasks. + +## Recovery and request peers + +Activation first requires completion or explicit abandonment of any preparation. +It preserves packet-number spaces, retained information, stream state, H3 state +and flow offsets.

These rules follow +[RFC 9000 sections 12.2, 13.2.7, 14.1 and 14.4](https://www.rfc-editor.org/rfc/rfc9000.html). + +## Atomic sends + +Recovery owns one bounded datagram transaction. Begin, prepare one packet per +space, protect every packet, and check all actual lengths before submitting UDP. +Every preparation retains its burned packet number, information slice, ACK +snapshot and flow reference. Successful emission commits all records without +allocation. Proven-unsent completion abandons the whole transaction and charges +no flow, pacing, amplification, PTO grant or PMTU attempt. Pending transactions +prevent identity activation and unrelated packet preparation. + +The final check enforces the total path allowance, minimum Initial size, write +keys, and aggregate congestion/pacing admission. Any ordinary data packet keeps +the ordinary/control window reserve in force. Only a batch consisting entirely +of in-flight PTO probes can use the PTO exception. The fixture owner reserves +amplification credit once for the complete datagram and retains each packet's +individual flight bytes. It can coalesce later ready handshake packets when a +large Initial occupies the first datagram by itself. + +## Discovery and fallback + +PMTU probes are standalone Application PING plus PADDING packets. They require +handshake confirmation and a validated active path. One search probe may be +outstanding; the next candidate advances 128 bytes toward the peer/local +intersection. Preparation and unsent completion do not start attempts or timers. +The emitted preparation token identifies the current search generation. Only a +new, validated ACK for that probe, on its active path and before its explicit +PTO-derived deadline, can confirm its actual emitted size. Timeout releases its +flight once, without reducing the congestion window or contributing persistent +congestion evidence. Three failed attempts impose a cooldown of ten current +application PTO intervals. Later owner send opportunities can resume discovery. +Failed discovery alone preserves an already confirmed working size. + +Sent records retain the actual datagram size and identity. Delivery of any +constituent marks all surviving records delivered, even after the ACKed record +is collected. Coalesced packets cannot count as separate black-hole failures. +Three unsuccessful PTO recovery opportunities in the affected packet-number +space involving distinct larger +ordinary datagrams reduce ordinary sends to 1200 bytes and enter the same +cooldown. Relevant progress clears suspicion. PTO expiry grants fresh packets +rather than declaring all outstanding packets lost. Retained STREAM/CRYPTO +information is encoded again under the reduced allowance; offsets, FIN and +alias completion remain authoritative. A late ACK of an older alias completes +information at most once. + +Sizing updates preserve congestion recovery history, additive growth credit, +and pacing debt; they update the minimum window, burst bound and stream quantum. +Deficit credit is clamped on shrink.

Normal TLS progression, stream +delivery, retained output and recovery completion forwarding stop immediately. +Protocol closure does not populate the fixture's diagnostic failure string. + +The owner performs one cancellation fan-out through +`http3_request_engine::disconnect()`, freezes identity work, and stops TLS provider +work. Pending packet/debit storage stays pinned until the actual completion. +Possibly emitted and ambiguous sends consume amplification debit; only proven-unsent +sends release it. Late completions retire ownership without forwarding new +application effects. Duplicate completions after termination are harmless. +Destruction conservatively treats an unresolved preparation as ambiguous. + +Once pending output settles, request engines, application file handles, transport +streams and flow state are released. Handler-initiated closure defers that +retirement until the current receive turn returns, so its borrowed stream references +stay valid; subsequent frames from the packet cannot start another handler. Local close prepares one bounded protected terminal +datagram. It contains only CONNECTION_CLOSE and padding, bypasses ordinary reliable +information/retransmission scheduling, and uses the selected path's amplification +budget.

TLS secret installation cannot resume after terminal +claim. Draining/closed clears all remaining packet-key generations; repeated clear, +expiry and destruction do not release key storage twice. Server Initial keys retire +after accepted Handshake processing and Handshake keys retire on confirmation. +Confirmation publishes the updated recovery environment immediately, so a close +before the next timer turn uses the confirmed PTO and peer ACK delay. + +The fixture's separate watchdog detects test hangs. It does not implement negotiated +idle timing. HTTP/3 GOAWAY/graceful application drain and public H3 listener enablement +remain their own tasks. + +## Stateless reset + +Peer reset tokens are copied with their CID records. Advertisement alone does not +make a token eligible: the owner must report successful or ambiguous emission using +that live peer CID on the remote endpoint. Each CID has at most three remote endpoint +associations, within the existing 32-record CID history. Proven-unsent preparation, +wrong remote endpoints, near-match tokens and retired IDs cannot authorize reset. +Retirement removes associations and their dispatch registrations; final detachment +also removes eligibility in identities without listener registrations. + +Both identity and listener compare fixed 16-byte tokens with `constant_time_equal`, +scanning their bounded registries without token-dependent early exits or secret hash +keys. Tokens come from the end of a whole datagram of at least 21 bytes. Listener +fallback handles unrelated or unparseable destination CIDs, using the existing +owner port, queue limits and retirement generation. Known-CID packets reach the +owner, which detects reset only after the first packet cannot authenticate. +Duplicate token/endpoint registrations cannot redirect another owner. If an +actual emission cannot register reset eligibility because capacity is exhausted, +the owner retires that completion/debit before claiming a local INTERNAL_ERROR +close; it never retries the already completed send.

A peer must send +that value in a completely validated SETTINGS frame before the first byte of +an opening HEADERS frame reaches the connection parser. Missing or zero values +disable Extended CONNECT; values above one and duplicate settings cause +`H3_SETTINGS_ERROR` (0x109). A later malformed pair cannot publish partial state. +Opening eligibility survives fragmented frame headers, payloads and QPACK +blocking. Ignored frames preceding the opening HEADERS do not freeze it early. +Ordinary requests still work before peer SETTINGS. + +A WebSocket route is an ordinary registered CONNECT coroutine route that calls +`co_await x.upgrade(options)`. The semantic head retains CONNECT, exposes the +canonical origin path for matching and the effective authority as Host, and +excludes pseudo-headers from ordinary fields. The original two-argument private +HTTP/3 converter still rejects CONNECT; the request engine uses a metadata +overload. No legacy WebSocket registry or new public routing API is involved. +Unregistered paths receive 404; CONNECT routes may respond normally without +upgrading. Premature or malformed CONNECT, including ordinary CONNECT, resets +only its stream with `H3_MESSAGE_ERROR` (0x10e). + +The HTTP/3 handshake adapter reuses policy, origin, version and subprotocol +validation with HTTP/1 and HTTP/2. HTTP/2 and HTTP/3 share the finite-body and +negotiation-field checks without changing HTTP/2 eligibility. Unsupported +protocols and schemes receive typed refusals; finite-body metadata, invalid +options and policy failures leave ordinary response handling available. An +unsupported version suggests 426 and `Sec-WebSocket-Version: 13`. Subprotocols +follow server preference. Extension offers are ignored, with no extension +response field, HTTP/1 upgrade headers or accept hash. + +Successful admission returns an application session and queues exactly one +stream-local QPACK HEADERS section with status 200, optionally a selected +subprotocol, and no FIN. Internal codec caps match the established HTTP/2 +bounds. Session storage is reserved against the QUIC pool's ancestor budgets +before allocation; QUIC wire storage uses the separately charged pool envelope. +Allocation and HEADERS refusal release provisional charges and leave an error +response available. Cancellation and destruction release the owned driver and +reservations. The handler may finish while the upgraded stream stays owned; +repeated upgrade or response decisions are refused. Sibling requests progress. +Admission also rejects draining, cancelled or disconnected streams and a known +received FIN, including FIN received beyond a reassembly gap. + +Allocation fault injection exposed two necessary shared fixes: `fields::entries()` +can allocate its lazy view cache, so it now propagates allocation failures instead +of promising `noexcept` and terminating.

During quic-go's +third rebinding the small PATH_CHALLENGE and matching response reached the new +port, but no padded validation challenge followed. The old path's stranded +flight consumed the shared congestion window; the candidate's validation packet +was incorrectly gated by that old window while its application ACKs were +withheld until validation. This circular wait was independent of the CID repair. + +Candidate validation probes now use a separate aggregate initial window of +12,000 bytes, shared by all candidate controls.

All protocols execute the same semantic +handlers; H1 uses the real poll/worker connection owner and H2 uses the actual +HTTP/2 engine and HPACK codec. +The H1 observer retains the bounded socket transcript in `wire_hex` and splits +the framer's ordered fields at the actual initial-header block boundary. Field +names do not determine trailer placement. The `http3_semantic_h1` regression +rejects header-only `x-reply` as trailer evidence and accepts the actual chunk +trailer, including segmented input and repeated names across both blocks. + +## Native observations and bounds + +The fixture assigns monotonic event numbers and captures each stream identity +when its handler enters. Uploads wait for an actual server prefix-read event. +Cancellation requires exactly one matching server event. Targeted snapshot, +release and drain commands refer to the accepted connection/stream. + +Slow consumers leave one awaited writer pending because transport credit and +bounded response storage are exhausted. The observed snapshot has five started +writes and four completed writes. The 4 KiB stream window leaves 16 MiB of +connection credit available to sibling/control streams. aioquic 1.3.0 normally +grows credit from received offsets; this test adapter suppresses only the +selected stream's `_write_stream_limits` during the withholding phase. It keeps +ACKs, other stream credit and the native H3 handler running. quic-go uses its +native 4 KiB receive window without reading the selected response body. +Both qlogs must independently show credit exhaustion, sibling FIN, subsequent +MAX_STREAM_DATA and resumed response FIN in that order. + +The aioquic observer records actual GOAWAY control payloads while retaining its +native handler. quic-go's public API has no received-ID observer, so the gate +uses tshark's decrypted incoming H3 frame payloads. The late request stream is +opened before drain; its headers are sent after both received GOAWAY stages. +A server `drain_started` event alone cannot satisfy the gate. The drain ticket +wait runs outside the serialized UDP owner with a five-second deadline. +The runner refreshes the live capture snapshot only while decoding a valid +incomplete received-stage prefix. It acknowledges the client only after both +actual incoming IDs match the initial maximum and accepted-stream cutoff. +Malformed rows/integers, incorrect stages, capture failures and decoder failures +fail immediately. Refreshes and decoder execution share the original ten-second +witness budget, clipped to the earlier case and five-second drain deadlines; +an absent stage at that deadline fails closed. The final decoder metadata +retains the snapshot hash and observation-attempt count. + +Connections retain their existing 15-second lifetime. The fixture caps four +connections, 16 active semantic requests per connection, executor turns, 64 KiB +uploads, 512 KiB response accumulation, 16 MiB capture bytes and diagnostic +output. Evidence directories are private; TLS secrets have mode 0600. +`packets.pcap` contains real application-boundary datagrams with synthesized +IPv4/UDP envelopes, rather than an interface capture. + +## TASK-191 drain scheduling clarification + +A successful drain requires the accepted response FIN and required control/QPACK +information to retire through actual QUIC ACK completions. A clean peer close is +not proof of receipt of that FIN. If the peer closes first, the ticket reports an +immutable incomplete outcome, even when its application close code is H3_NO_ERROR. +The fixture's historical `drain deadline expired` diagnostic also covers this +interrupted outcome; it does not establish that five wall-clock seconds elapsed. + +The pinned quic-go H3 client automatically closes after GOAWAY when its last +tracked request reaches EOF. Its application can consume that EOF before the +native delayed ACK for the server FIN is sent. The original immediate-EOF schedule +is therefore a legal negative case, retained in the protected owner regression. +A naive ACK-before-read observer is also invalid: remote CONNECTION_CLOSE makes +this stack discard unread response data. + +The positive client schedule preopens one additional client-only stream (ID 8) +before drain, sends no bytes or FIN on it, and retains it through the actual native +FIN ACK and remote server closure. It is not server work or a drain dependency. +The original accepted stream 0 and preopened rejected stream 4 remain unchanged. +The native tracer observes exact packet ACK coverage; qlog validation independently +requires FIN → covering ACK → authenticated server application close 256. It also +rejects any wire frame or server event naming the local hold. After remote closure, +the client cancels each half of that local stream once. The observation and closure +share the original five-second drain budget; no sleeps or synthetic ACKs are used. +This scheduling amendment was explicitly authorized for TASK-191. + +Final fixture `traffic` records are teardown capture accounting. The live runner +validates their bounded integer shape and uniqueness, then waits for the actual +process exit. Nonzero fixture exit and its captured causal stderr remain the +primary error. Accounting cannot acknowledge semantic work or replace a receipt; +unknown lifecycle events, duplicate/malformed accounting and lifecycle output after +accounting fail closed. Successful runs still require exactly one accounting record +and exact packet/byte reconciliation against the unchanged capture. + +## Provisioning and reproduction + +Local tools: Clang 18 (C++20 in actual compiler output), Python 3.12, Go 1.26.9, +and tshark 4.6.4.

The observer +checks exact payloads, opcode, FIN and unmasked server output independently of +DATA boundaries. An unmasked client frame must terminate just that stream, +produce one `protocol_error` callback, and leave an HTTP health sibling usable. + +A second verified connection holds `GET /hold` through both scenarios: + +1. An echo tunnel receives STOP_SENDING and RESET_STREAM with + H3_REQUEST_CANCELLED (`0x10c`).

A flood tunnel reaches its advertised 4096-byte receive-credit boundary. + Its server snapshot must show an actual backpressured send and outstanding + `writable()` wait. Another health sibling completes while credit remains + withheld.

A timer or client boolean alone +cannot satisfy this gate. + +## Bounds and adapter seams + +The fixture allows four connections with a 15-second owner watchdog. The gate +uses three connections, per-case deadlines and a 40-second process deadline. +It caps diagnostic output, queued events, commands and observations. The client +caps pending streams at 16, frame queues/counts at 256, server payloads at 8192 +bytes, buffered wire at 1 MiB and HTTP sibling bodies at 64 KiB. + +Shared fixture routes use public exchange/session operations, 8192-byte incoming +messages, one incoming/outgoing message and 8202 bytes of outgoing capacity. +The extra ten bytes accommodate the server admission policy's conservative +frame overhead. Every `try_send` disposition is checked; backpressure suspends +and retries. The flood waits for its last frame to leave the codec before +`close()`, which can otherwise discard queued application data. Neither +`writable()` nor an accepted send proves peer delivery; the client independently +checks every received byte. Sessions remain alive through their close callback, +and observations remain until fixture teardown to detect duplicate callbacks. + +The pinned test adapter reuses TASK-174's `_write_stream_limits` seam to withhold +only the selected stream's receive-credit updates. ACKs, connection credit +(16 MiB), and ordinary streams remain active. `SemanticClient` accepts an H3 +factory so only one set of critical streams is opened. The SETTINGS observer +calls native `_handle_control_frame` first, records validated +`_received_settings`, and appends `http:settings_received` to the same qlog. +This is an explicit client observation added by the test adapter; other HTTP +headers and transport credit/reset/FIN events come from aioquic's native logger. +The version and seams fail closed if unavailable. + +The external gate exposed a server cancellation-reason defect: STOP_SENDING +`0x10c` arriving before RESET_STREAM reported `protocol_error`.

Corpus formats and seed coverage are documented in +`test/data/quic/recovery/README.md` and `test/data/quic/callbacks/README.md`. + +Both targets cap input at 4096 bytes, events at 64, and generated payloads at +16 bytes. Every input runs twice against fresh state; normalized observations +must match. Storage, receive ranges, sent packets, information records, leases +and datagram batches have independent ceilings. Final reservations must be zero. +Logical timer increments are bounded and monotonic. Close interleavings are +owner-serialized. Queued events never call through freed callback arguments. + +Compiler: `/usr/bin/clang++`, Ubuntu Clang 18.1.3. Native provider: +`/home/etr/progs/libhttpserver/build/tooling/provider`, OpenSSL 3.5.9. +TLS-off configuration uses `--disable-v3-tls --disable-examples`, and TLS-on uses +`--enable-v3-tls --disable-examples`; both use `CC=clang CXX=clang++` and +`CXXFLAGS='-std=c++20 -O1 -g'`. TLS-on explicitly sets: + +```sh +V3_TLS_CFLAGS=-I/home/etr/progs/libhttpserver/build/tooling/provider/include +V3_TLS_LIBS='-L/home/etr/progs/libhttpserver/build/tooling/provider/lib -lssl -lcrypto' +``` + +The fuzzer compiles project sources directly with +`-fsanitize=fuzzer,address,undefined -fno-sanitize-recover=undefined`, C++20, +`-O1 -g -fno-omit-frame-pointer`. It includes v3core sources for recovery and +v3core plus v3tls sources for callbacks, rather than ordinary project archives. +Provider flags come from literal configured Makefile substitutions parsed into +argument arrays without shell evaluation. Wrong TLS mode, missing or malformed +provider flags, missing instrumentation and empty corpora fail explicitly. +Existing default targets are unchanged. + +Initial fuzz build/run commands from the worktree root: + +```sh +ASAN_OPTIONS=detect_leaks=0 UBSAN_OPTIONS=halt_on_error=1 \ + scripts/run-v3-protocol-fuzz.sh --compiler /usr/bin/clang++ \ + --build-dir build/task176-fuzz-off --native-config-dir build/task176-off \ + --targets quic_recovery --runs 2000 --seconds 30 +ASAN_OPTIONS=detect_leaks=0 UBSAN_OPTIONS=halt_on_error=1 \ + scripts/run-v3-protocol-fuzz.sh --compiler /usr/bin/clang++ \ + --build-dir build/task176-fuzz-on --native-config-dir build/task176-on \ + --targets quic_tls_callbacks --runs 2000 --seconds 30 +``` + +The local repair reran each generated `reproduce.sh` with those sanitizer +environment settings against the existing evolved build-local corpus. Generated +`compile.sh` records exact compiler arguments, `sources.list` records instrumented +project sources, `provider.log` records configured linkage, and `environment.log` +records compiler and revision. Each invocation uses seed 128, 2000 runs, +30-second total ceiling, 5-second per-input timeout, 512 MiB RSS ceiling, and a +separate artifact directory. Build-local corpora may grow; tracked authored seeds +remain unchanged. + +## Local results + +Prior-session baseline logs report 4/4 focused tests in each TLS configuration. +The repair reproduced three failed TLS owner assertions: a test expected an +incoming CRYPTO packet to execute while a submitted send was pinned. The owner +intentionally drops payload in that interval. The repaired test first asserts +active state and no close, completes the send, then redelivers the delayed packet. +Malformed post-handshake CRYPTO invokes the actual provider alert callback and +ordinary close arbitration in the network fixture. The test verifies one close, +cancellation of suspended handler work, rejection of later datagrams, application +key disposal and full storage release, both with and without a preceding send. + +| Check | Result | Local log | +| --- | --- | --- | +| TLS-off focused C++20 suite | 17/17 pass | build/task176-off/focused-repair.log | +| TLS-on focused C++20 suite | 6/6 pass | build/task176-on/focused-repair.log | +| Recovery replay | 5 tests, 12 checks; 325 corpus/mutation/prefix cases | build/task176-off/test/quic_recovery_fuzz_replay.log | +| Callback replay and real owner handshake | 7 tests, 38 checks; 585 corpus/mutation/prefix cases | build/task176-on/test/quic_tls_callbacks_fuzz_replay.log | +| Fully instrumented ASan/UBSan replay suite | 2/2 pass, including real-handshake close interleavings | build/task176-san-on/replay-repair.log | +| Recovery ASan/UBSan fuzzer rerun | 2000 runs, cov 2056, ft 4880, peak reported RSS 251 MiB | build/task176-fuzz-off/quic_recovery/repair-run.log | +| Callback ASan/UBSan fuzzer rerun | 2000 runs, cov 951, ft 2078, peak reported RSS 403 MiB | build/task176-fuzz-on/quic_tls_callbacks/repair-run.log | +| Runner preflight tests | 7/7 pass | build/task176-off/runner-repair.log | +| Native linkage audits | Pass in TLS-off and TLS-on | build/task176-{off,on}/linkage-repair.log | +| Changed C++ files cpplint | Pass | build/task176-off/lint-repair.log | +| Source distribution staging | Pass | build/task176-off/dist-repair.log | + +The TLS-off suite selects quic_fuzz_replay, quic_recovery_fuzz_replay, +quic_reassembly, quic_ack_state, quic_recovery, quic_repacketize, +quic_flow_control, quic_flow_recovery, quic_flow_storage, quic_congestion, +quic_pacing, quic_send_schedule, quic_connection_identity, quic_path_mtu, +quic_datagram_sizing, quic_connection_lifecycle and v3_native_linkage. +The TLS-on suite selects quic_recovery_fuzz_replay, +quic_tls_callbacks_fuzz_replay, quic_tls_session, quic_tls_handshake, +quic_recovery_tls and http3_network_owner.

Whole-slice delivery +can hold "ab" while one-byte delivery holds "a", with "b" awaiting another +release. The same finite release schedule can also expose a different EOF +frame extent. Those schedules now each require deterministic fresh replay +and retain every invariant independently. Auto-release profiles still require +cross-fragment equality of valid normalized observations or malformed errors. +Named regressions cover the held DATA schedule, subsequent EOF and RESET. + +The feed-call ceiling is now `2 * input_cap + event_cap + +(event_cap + stream_cap) * stream_cap`, or 9536. It accounts for consuming +calls, scheduler yields, explicit feeds, event pumps and final drain visits; +unbounded no-progress loops still hit the hard cap.

The QUIC runner invokes bare +`tshark` and `editcap`; the declared decoder must match PATH, and the key-log +injection helper must be available before starting the matrix. + +The private output directory retains `manifest.json`, inventory/source hashes, +compiler and tool identities, provider hashes, exact command arrays, duration, +exit status, native counts, corpus and binary hashes, and child runner receipts. +A failed stage preserves earlier results. Existing output directories are +rejected intact. Do not commit certificates, TLS keys, captures or build output. +TASK-173 simulator captures retain their network topology; TASK-174/175 captures +are actual application-boundary datagrams in synthesized IPv4/UDP envelopes. + +The QUIC exclusions are copied verbatim from TASK-173. Extreme-loss 50-connection +multiconnect and IP-address rebinding are outside that bounded matrix; port +rebinding remains required for both selected peers. Transfer success requires +an additional authenticated zero-error close witness. The observed aioquic +rebinding limitation does not waive the selected peers' coverage. 0-RTT is +disabled; WebSocket extensions are refused. Baseline framing, critical stream +errors, compression limits, cancellation, trailers, GOAWAY and RFC 9220 +negotiation remain required. + +Fuzz targets are `quic_parser quic_state quic_recovery http3_engine qpack +websocket_codec` with TLS off and `quic_tls_callbacks` with TLS on. Each lane +requests 2000 runs with seed 128, a 30-second total ceiling, five-second input +timeout and 512 MiB RSS ceiling. The manifest records actual completed runs. +Project sources are compiled directly with libFuzzer/ASan/UBSan; ordinary +archives do not satisfy that gate. Configured sanitizer builds instrument +library, fixture and test compilation; the reused OpenSSL provider and +independent clients are outside that instrumentation. LeakSanitizer is disabled +in this local environment; deterministic reservation teardown and ASan/UBSan +remain required.

Artifacts +below are relative to the task worktree and remain retained as history.

Bash `%q` compile +receipts are parsed as arguments before checking instrumentation, without +executing their text. + +The standalone unchanged TASK-173 runner also failed quic-go handshake at +`build/task178-quic-probe-04` (11/12 cells passed). In the aggregate attempt's +named quic-go handshake captures, the simulator left interface recorded ten +client Initial datagrams, while its right interface recorded no QUIC traffic. +The endpoint's application-boundary capture contains only the simulator +readiness probe/reply. The client timed out and the upstream predicate reported +`Expected exactly one version. Got []`. This required wire/handshake proof is +missing. The separate rebind-port failure reported that the first server packet +on a new path lacked PATH_CHALLENGE. Its cause remains unverified; no required +predicate, timeout or exclusion was changed. Ownership triage belongs to the +TASK-173 transport/simulator maintainers; a valid current-source twelve-cell +matrix is the blocked dependency for TASK-178 acceptance. + +Earlier attempts are retained at `build/task178-full-01` through +`build/task178-full-03`. They include a corrected native corpus-summary adapter +failure, an interrupted run and failures before the missing editcap helper was +restored. No old receipt is treated as current passing evidence. Reproduction +and investigation notes are `/tmp/task178-debug-journal.md`. + +Exact tool identities observed in attempt04 are clang 18.1.3 (Ubuntu +1ubuntu1), Python 3.12.3, Go 1.25.1, aioquic 1.3.0, HTTP/3 quic-go v0.55.0, +OpenSSL 3.5.9 (2026-09-29), TShark/Editcap 4.6.4, Docker 29.1.3 and Compose +2.40.3+ds1-0ubuntu1. The independent transport peers are quic-go commit +`431fe2e3946b8d75c6db436a6866a83a91a24a7d` and picoquic +`1.1.47.0 / 7cafedfe53695357be230dec36a39952bf447898`. +The runner pin, peer/simulator digests and immutable image IDs are retained in +the QUIC manifest; the source-built endpoint image ID is +`sha256:79135c88906dc88461c7c15f49a42dcdd5ba2f495af2633d2b394aaa302dbcaa`. +Provider archive/header hashes and compiler/configuration receipts are in the +aggregate manifest and build directories. These identities describe attempted +verification, not a release approval. + +The dependency-free aggregate contract has 25 passing tests. Source-distribution +inclusion and public-header hygiene passed. The existing file-size check still +fails on unchanged `src/detail/io_poll_backend.cpp` (509 SLOC, limit 500); +its threshold was preserved. +The registered contract also passed through Automake using +`make -C build/task178-off/test check-TESTS check_PROGRAMS= TESTS=integ/http3_full_gate_runner_test.py`; +the separate native lanes above provide the required C++ executable evidence. + +## Historical resumed verification (2026-10-09) + +Fresh aggregate attempt `build/task178-full-05/manifest.json` again failed the +required TASK-173 matrix. All four native stages passed: TLS-off and sanitized +TLS-off each ran 48 suites/532 cases; TLS-on and sanitized TLS-on each ran 55 +suites/597 cases. Each selected native stage had zero failures and skips. +The matrix passed 10/12 cells: quic-go handshake failed with +`Expected exactly one version. Got []`, and picoquic rebind-port failed with +`PATH_CHALLENGE without a PATH_RESPONSE`. The quic-go rebind-port cell passed +in this attempt. Both failures and successful cells remain recorded in +`build/task178-full-05/quic-interop/evidence/results.json`; child cleanup exited +zero, and aggregate execution exited one. Later aggregate stages were not run. + +The named quic-go handshake capture again contains ten 1280-byte Initial +datagrams at the simulator's left interface and no UDP at its right interface. +The endpoint reported only the readiness probe/reply. Comparing the earlier +passing transfer capture shows 1280-byte client packets forwarded normally; +packet size alone does not explain this missing forwarding. Read-only inspection +of the pinned startup scripts found no verified cause. No client, simulator, +transport source, required predicate, timeout or exclusion was changed. +At that point, TASK-173 transport/simulator ownership triage remained the +blocked dependency; a valid current-source twelve-cell receipt was still +required for TASK-178. + +The aggregate, HTTP/3, WebSocket and fuzz runner contracts passed again (25, +21, 12 and 10 tests respectively). The QUIC runner contracts passed 25 tests; +four opt-in integration tests were skipped in that dependency-free invocation. +The registered aggregate Automake test passed 1/1 with zero skips/errors; +its log is `/tmp/task178-resume-automake-contract.log`. Python compilation and +`git diff --check` passed. The task card and index remain In Progress, and all +prepared changes remain unstaged for the runner. Original evidence was retained. + +## Local repair and passing aggregate (2026-10-09) + +The current passing aggregate receipt is +`build/task178-repair-full-02/manifest.json`. All nine required local stages +passed in one execution. Earlier failed receipts remain retained as history. + +| Required gate | Current result | +|---|---| +| C++20 TLS-off / TLS-on | 48 suites / 532 cases and 55 suites / 597 cases; no failures or skips | +| ASan/nonrecovering UBSan TLS-off / TLS-on | The same 48 / 55 suites and 532 / 597 cases; no failures or skips | +| TASK-173 QUIC | All 12 cells passed, with both authenticated zero-error closure witnesses and cleanup exit zero | +| TASK-174 HTTP/3 | aioquic and quic-go each passed all 11 scenarios | +| RFC 9220 WebSocket | aioquic passed all 11 scenarios | +| Instrumented fuzz | All six TLS-off targets and the TLS-on callbacks target completed 2000 runs each without sanitizer errors | + +Before repair, a standalone unchanged QUIC matrix passed all twelve cells at +`build/task178-repair-quic-01`, but aggregate reproduction +`build/task178-repair-full-01` failed quic-go transferloss and picoquic keyupdate. +The transferloss endpoint saw only readiness traffic. A focused diagnostic then +recorded the simulator scenario exiting with status zero before client readiness +at `build/task178-simulator-diag-06`; the client timed out and no handshake was +forwarded. The exact internal reason for that premature exit was not established. + +The task-local driver now explicitly selects `ns3::RealtimeSimulatorImpl` with +`NS_GLOBAL_VALUE` during process initialization, before scenario code can select +a simulator. The pinned simulator image, scenario parameters, peers, predicates, +timeouts and exclusions are preserved. The QUIC manifest records this setting +as `simulator_global_values`. Ten focused handshake reruns with the setting +passed at `build/task178-simulator-diag-07` through `-16`, followed by the complete +passing aggregate above. Diagnostic wrappers were used only for investigation; +the aggregate used the pinned simulator's original entrypoint. + +The setting regression failed before the repair and passed afterward. The QUIC +runner contracts passed 26 dependency-free tests (four existing opt-in tests +were skipped), and the aggregate contracts passed 25 tests. All changes remain +unstaged in the task worktree for the runner-owned commit flow. TASK-178 remains +In Progress pending the normal runner lifecycle. Nonlocal platforms remain +deferred to CI/the v3 PR; LeakSanitizer remains disabled as described above. diff --git a/docs/task-179-behavior-parity.md b/docs/task-179-behavior-parity.md new file mode 100644 index 000000000..92a705922 --- /dev/null +++ b/docs/task-179-behavior-parity.md @@ -0,0 +1,213 @@ +# TASK-179 behavior parity audit + +The audit replays all 29 committed v2 cases through production v3 dispatch and +real private transport owners. The six modes are HTTP/1.0 and HTTP/1.1 over TCP +and TLS, HTTP/2 over TLS, and HTTP/3 over QUIC. Golden expectations and recording +provenance remain unchanged. The bounded inventory includes every original +capability and completion-map row, plus certificate, SNI, client-certificate and +external-PSK outcomes: 60 capabilities, 360 protocol cells. + +## Protocol applicability + +The two HTTPS cases require encrypted transport. HTTP/1.0 has no supported +WebSocket Upgrade mechanism; its WebSocket handshake and echo cells are excluded +with that explicit rationale. TLS record and credential capabilities likewise +require encryption. All other golden cells execute. There are 168 applicable +corpus observations: 26/27 clear HTTP/1.0/1.1, 28/29 TLS HTTP/1.0/1.1, and 29 each +for HTTP/2 and HTTP/3. Applicability exclusions have their own recorded outcomes. + +## Protocol translations + +HTTP/1.0 requests explicitly request keepalive. Known-length bodies retain it; +unknown-length pipe/deferred bodies use EOF framing and close the connection. +This is the HTTP/1.0 migration of HTTP/1.1 chunking and persistence expectations. +Only request header blocks are translated; binary/multipart payloads are intact. + +HTTP/2 and HTTP/3 use numeric status, lowercased field names, DATA framing and +stream completion. The comparator still checks application status, exact body, +Content-Length when present, Content-Type, Allow, auth challenges, captures, +hook fields, repeated-field order and initial-header/trailer separation. Request +Connection fields and fields they nominate are removed. Methods, target/query, +authority, ordered application fields and binary body are preserved. Pipelining +becomes two stream-correlated responses on one connection; connection-wide +response ordering is an HTTP/1 contract. Every persistent corpus exchange has a +successful ordinary follow-up on that same connection. + +ICY is asserted literally on HTTP/1. The same marked response becomes numeric +200 with the same body on HTTP/2/3; no synthetic ICY status line is recorded. +WebSocket uses the pinned fixed-key 101/Accept handshake on HTTP/1.1, and Extended +CONNECT numeric 200 without Upgrade/Accept fields on HTTP/2/3. All supported +modes verify independent masked text echo and close 1000; multiplexed modes +also verify stream completion and an ordinary sibling request on the connection. + +The aioquic 1.3.0 client omits outgoing HEAD context when checking response +Content-Length. The bounded client adapter records HEAD streams, permits their +representation length with zero DATA and rejects any HEAD DATA. Other methods +retain the original length validator. A regression verifies all three cases; +the received headers and body are never rewritten. + +## Routing migrations + +v3 registration order replaces v2 literal-before-parameter tiers. Register +literal siblings first to retain v2 precedence. Prefix depth and catch-all +behavior remain. Regex routes and segment regex constraints move into application +handlers or a prefix wrapper. The named registration/family tests verify the +current surface, rather than claiming removed regex overloads execute. + +## Hook migrations + +The native bus retains seven request phases plus listener accept_decision. +MHD connection-open/close notifications and body_chunk are omitted; use typed +admission, request completion, transport peer snapshots and the handler read loop. +Per-resource hooks become route-handler wrappers. Alias setters become page +factories, auth guards and response/completion hooks. Throwing or invalid page +factories degrade to default 404/405; throwing exception hooks preserve the +contained empty-body 500. Named ordering, snapshot and containment tests supplement +the real hook corpus over every applicable transport. + +## Peer policy migrations + +The native policy uses typed outcomes and peer_refusal reasons, literal/CIDR and +trailing IPv4 wildcards; middle wildcards are rejected. Mapped IPv4 normalizes, +forwarded headers do not change identity, and unspec identity has explicit rules. +Each request revalidates its immutable transport peer against the live policy. +The wire probes admit loopback, mutate the policy, and verify the next request +has zero application response bytes: EOF on HTTP/1, stream reset on HTTP/2/3. +In-flight responses complete before the next refusal. H2's snapshot comes from +getpeername; H3 uses the UDP owner's admitted/validated peer. Existing H3 tests +also verify snapshot stability across validated rebinding. + +## Request and source migrations + +v3 retains raw escaped target/query, ordered fields and separate trailers; it +has no merged v2 query/form/path map. Applications opt into bounded decoders; +path captures use exchange::path_args(). Cookies use the owned `http::cookie` value, +`http::parse_cookie_header` and typed `http::render_set_cookie` operations with +ordered Cookie/Set-Cookie fields. TASK-192 supplies the installed helper and the +`http_cookie` suite with all three capability-054 identities. Receipts bind named +checks to the actual executable/hash, command, complete log and executed counts; +semantic supporting evidence does not claim per-protocol wire observations. Request bodies are pulled and footers +are accessed after end-of-body. Malformed encodings and limits return typed errors. +Multipart disk sinks have explicit abort cleanup, keep-once callbacks and sanitized +names, verified by named decoder and disk lifecycle tests. + +Files are really opened; missing files map before commit to sanitized 500, empty +files stay empty. Owned pipes are one-shot; borrowed bytes require a retained lease; +deferred producers are per-send factories. Named source/definition tests verify +concurrency, replay, retained storage and failure cleanup. These common semantic +tests are labeled semantic; H2/H3 framing suites are labeled engine-frame, while +the golden body observations come from TCP/TLS/QUIC owners. + +## TLS capabilities + +Certificate generations, SNI/ALPN selection, optional/required client authentication +and external PSK have named provider/BIO and real TLS socket policy evidence. +TLS record segmentation is provider-owned and never was a pinned application +contract; fragmented authenticated I/O is verified. External PSK remains HTTP/1 +only: server_options::check_psk_protocols rejects H2/H3, tested by +server_options_validate:psk_limited_to_http1. PSK lookup bounds, cancellation, +identity policy and provider retry behavior are exercised, rather than skipped. +TLS-off server_options tests prove typed encrypted-feature unavailability and do +not count as successful encrypted transport observations. + +Public server::listen() still rejects TLS/H2/H3 before binding. The named +native_server:unsupported_transports_rejected_before_any_bind test records this +release integration gap. Private owner evidence proves protocol/application +behavior; it does not claim public encrypted listener availability. Full public +listener integration is outside this audit's scope. + +## Repaired defects and TDD evidence + +H2/H3 formerly used run_route and lost captures, 405/Allow/default body and hook +composition. Their parity regressions failed four checks per protocol before +both engines adopted dispatch_request and a stream-owned lifecycle_sink. The +optional internal owner-lifetime context supplies hooks, page factories, policy +and transport peer. Protocol head refusal suppresses successful response_sent. +Cancelled queued/parked requests now complete exactly once via the existing +lifecycle guard; separate cancellation regressions reproduced the missing +notification. Historical RED logs: build/task179-off/{h2,h3}-red.log and +build/task179-on/{h2,h3}-cancellation-red.log. + +HEAD sync values previously attempted a payload write and broke persistence. +route_sync:head_value_keeps_length_without_writer_traffic failed eight checks +across the four protocol versions before retaining representation length while +committing without body traffic. Historical RED/GREEN logs remain under +build/task179-on/focused-results/route_sync-head-*.log. + +HTTP/1 TLS needed a private tls_socket_backend composing encrypted application +operations with raw timers, wakeups and socket ownership. Its native corpus also +exposed WebSocket handoff cancellation aborting the whole established TLS session. +The new plaintext-read cancellation regression failed six checks, plus the TLS +WebSocket corpus. The private socket owner now requests a nonfatal serialized +plaintext-reader cancellation policy; default TLS adapters retain session-abort +semantics, and control/write cancellation and deadlines still abort. Both direct +and operation-based cancellation preserve established I/O, and the independent +TLS WebSocket handshake/echo/close passes. RED/GREEN: +build/task179-on/tls-read-cancel-{red,green}.log. + +The live runtime-deny probes exposed a further H2/H3 defect: semantic peer +refusal emitted no wire reset and retained stream capacity. Both focused exchange +regressions failed the reset and single-slot reuse checks; the actual TLS/QUIC +clients timed out. The stream reapers now emit REFUSED_STREAM / H3_REQUEST_REJECTED +for that completed, refused exchange. They release capacity without application +headers/body and preserve exactly-once peer_refused completion. RED logs remain +under build/task179-probes/{h2-policy-engine,h3-policy-unit,h3-policy-engine}-red.log. + +The request-sequence helper was tested before implementation for pipeline splitting, +binary bodies, malformed lengths, bounds and multiplexed field translation. The +fail-closed receipt checker has mutation tests for missing/duplicate capabilities, +corpus additions, cells, outcomes, logs, exits, malformed/unfinished observations, +skips/defects, stale input hashes, named checks and prohibited semantic waivers. +Named tests cannot be replaced by a process starting or exiting zero. + +## Reproduction and retained evidence + +Worktree: /home/etr/progs/libhttpserver/.worktrees/TASK-179; branch task/TASK-179; +base v3 at 7a0e850d23308ade4da0a1b2648f4a7bd0c2e80f.

Each of its four saturated cases now has +three equal one-second CPU observation windows with an idle peer/observer. +`CLOCK_PROCESS_CPUTIME_ID` includes the actual server workers and sleeping +observer in that executable; it is not an independent server-only measurement. + +`scripts/lib/resource_limits_probe.py` measures separate running server +processes through Linux `/proc//stat` (user + system CPU ticks) and `statm` +(current RSS, not historical maximum). Its independent clients retain bounded +per-stream responses and bounded transcripts. It performs three output +saturate/reset/refill cycles and three upload saturate/reset/refill cycles for +both TLS H2 and protected UDP H3, plus ordered response resumption. Production +receive credit bounds client uploads; no illegal excess DATA is sent to defeat +flow control. Additional actual PING pressure uses 64 and 512 control frames; +H2 stays below the production control-rate gate and checks every PING ACK. H3 +keeps ACK/PING active and completes a PING future. These are control-frame +pressure windows, not claimed 1/8 MiB network data attempts. The H1 probe owns +those attempted-byte measurements. Each stalled window permits at most 20% +of one CPU core and each warm RSS comparison permits at most 1 MiB growth. +A 90-second top-level deadline and bounded fixture shutdown enforce cleanup. + +The final network receipt is `build/task180-probe-08/receipt.json`, with bounded +server logs, ephemeral credentials and a datagram capture in the same directory. +The H3 probe stays within the existing owner's initial sixteen bidirectional +transport streams. It does not claim transport MAX_STREAMS replenishment. + +| Normal network witness | Saturated actual usage | Post-reset baseline | Ordered resume | +| --- | --- | --- | --- | +| H2 output | response 20608 B; header 540 B; body 18472 B; 1 request stream | response 4096 B; body 16512 B parser reserve; headers 0; streams 0 | 131072 exact `L` bytes | +| H2 upload | body 84135 B; header 720 B; accepted stream input 16384 B and zero remaining stream credit | body 16512 B; headers 0; streams 0 | reset/readmission plus existing upload-flow transfer | +| H3 output | response 16512 B; body 16512 B; header 900 B; 4 peer streams | response/body/header 0; 3 fixed peer critical streams; 5242880 B prepaid QUIC envelope | 524288 exact pattern bytes, one FIN | +| H3 upload | body 16512 B; header 1200 B; 131072 B supplied; sender offset and credit both 65573 B, with unsent data parked | body/header 0; 3 fixed peer critical streams; same envelope | reset/readmission with sibling 204 | + +All three output and upload cycles returned to these exact semantic baselines. +The QUIC envelope survives while the owner exists and is released by its +storage lease lifetime; queue destruction is not incorrectly asserted to free +closing/CID state immediately. Actual-owner unit tests verify full destruction +release and late/idempotent terminal behavior. + +The six H2 one-second CPU samples were 0, 0, 0, 0, 0, .02 seconds; +RSS stayed at 9699328 B throughout. H3 measured CPU was zero ticks in all six +windows (10 ms measurement resolution); its warm RSS range was 11272192–11534336 B, a 262144 B increase, within +1 MiB. Every sample retains CPU/wall/RSS values in the receipt. Pressure CPU, +actual accepted response bytes and control counts are recorded separately. +The TLS-off H1 log is `build/task180-off/test/native_protocol_memory.log`: its +four queue snapshots were 4096/4096, 1024/1024, 2122/2122 and 462/462 bytes; +RSS was unchanged within each pressure pair. CPU samples were below .001 +seconds per one-second idle window. + +## Reproduction and local evidence + +Use `./bootstrap`, then fresh VPATH directories. Normal configurations use +`CC=clang CXX=clang++`, `--disable-examples`, C++20 `-O1 -g`, and either +`--disable-v3-tls` or `--enable-v3-tls`. TLS-on uses the existing OpenSSL 3.5.9 +QUIC-capable provider at `/home/etr/progs/libhttpserver/build/tooling/provider` +with explicit include/library flags. The compiler is Clang 18; client pins are +hyper-h2 4.4.1 and aioquic 1.3.0. The pinned environment is +`build/task180-clients`, provisioned explicitly rather than inside a gate. + +```sh +build/task180-clients/bin/python scripts/lib/resource_limits_probe.py \ + --h2-fixture build/task180-on/test/http2_tls_fixture \ + --h3-fixture build/task180-on/test/http3_udp_fixture \ + --output build/task180-probe-fresh +``` + +Build all `src` libraries before tests: some H1/public tests link the legacy +public shared library embedding v3core; rebuilding only the static core leaves +stale behavior. Build focused executables explicitly, then run Automake +`check-TESTS check_PROGRAMS= TESTS=''`. The dependency-free Python +receipt contract is also registered with Automake and checks CPU spin and +RSS-growth rejection. + +RED logs are retained under `build/task180-off/test/resource-limits-red*.log` +and `resource-limits-trailers-red2.log`: missing H1 head/body/output/early/WS +charges, H2/H3 seats, missing H3 ancestry and unreleased cancelled stream seats +were observed before repairs. A long H1 response initially exhausted historical +output charges after transmission; retirement now permits all 128 refill +turns. The trailer RED case refused neither shared fields nor their storage. +Network probe RED demonstrated unavailable real-owner budget snapshots. +The first control-pressure attempt correctly received H2 overload GOAWAY; +subsequent probes retain the production rate limit and pace legal pressure. +A longer first H3 probe exhausted its fixture's fixed transport stream count; +the bounded final scenario respects that existing owner contract. + +An additional H1 tail regression observed retained heap capacity and a stale +144-byte reservation after the consumer drained all pending input. The owner +now frees empty tail allocations before returning capacity and reconciles +charges after refeed; partially consumed tails retain their allocation charge. +Its RED receipt is `resource-limits-tail-red.log`. + +Sanitized configurations add `-fno-omit-frame-pointer`, +`-fsanitize=address,undefined -fno-sanitize-recover=undefined`, matching linker +flags, `ASAN_OPTIONS=detect_leaks=0` and `UBSAN_OPTIONS=halt_on_error=1`. +LeakSanitizer cannot run under this environment's ptrace supervision; the +provider archive is separately uninstrumented. Sanitizer behavioral results +are kept separate from normal RSS/CPU measurements. + +The supported TSan lane uses `-fsanitize=thread` with the existing +`test/tsan.supp` limited to documented libstdc++ ctype-cache races. Its global +allocator owns operator new/delete. The existing WS drain race fixture now +uses the repository's sanitizer-owned allocator convention: all actual race +cases execute, while its non-race allocation fault injection reports one +explicit internal case skip under TSan. That fault-injection case executes in +normal and ASan/UBSan lanes; it is not reported as TSan proof. The original +linker conflict and repaired build are retained in TSan build logs. + +Final current-source local receipts: + +| Lane | Passed suites | Receipt | +| --- | --- | --- | +| Normal TLS-off | 33/33 | `build/task180-off/check-complete.log` | +| Normal TLS-on | 34/34 | `build/task180-on/check-tail-current.log` | +| ASan/nonrecovering UBSan TLS-off | 32/32 | `build/task180-asan-off/check-tail-current.log` | +| ASan/nonrecovering UBSan TLS-on | 33/33 | `build/task180-asan-on/check-tail-current.log` | +| TSan affected H1/race owners | 5/5; one non-race fault-injection case explicitly skipped | `build/task180-tsan-off/check-tail.log` | + +The final resource-owner suite passes 19 cases and 762 checks in all five lanes; final task-local additions +also prove H1 WebSocket child refusal with free parent capacity, parent +saturation across sibling connections, and reuse after real socket closure. +The final added case was rerun in all five lanes after the full focused sets +above passed. These combined results verify 502 C++ cases in TLS-off and 535 +in TLS-on, plus the Python contract and normal allocator executable. +Their five-lane receipts are `build/task180-/check-resource-final.log`. Normal and +ASan/UBSan selected suites have no skips or errors; the independent Python +contract adds three passing receipt tests. Normal lanes additionally run the +RSS/CPU executable; sanitizer lanes verify behavior without allocator plateau +claims. TLS-on also runs the actual QUIC/TLS network-owner suite. +An intermediate ASan-on run picked up the new tail regression against its +previous static core and failed that case; the final receipt above rebuilt all +source libraries and passes it. The stronger H3 upload witness initially found the supplied 64 KiB had all +fit the current credit. Its final probe supplies a fixed 128 KiB buffer and +asserts both an exhausted actual send window and remaining unsent data. +A prior compile overlapped a test-file write; +its failed compiler log is retained and the final builds used the stable source. + + No tests were +substituted for required network evidence, no public metrics/API were added, +and the protocol/control admission guards were preserved. + +The unchanged file-size gate still reports `src/detail/io_poll_backend.cpp` +509 SLOC against 500. Changed sources remain below the gate; the threshold was +not relaxed. Changed C++ paths pass cpplint, Python compiles and `git diff +--check` passes. Runner-owned publication and task completion follow this +implementation handoff; the task card remains In Progress. + +## Validation recovery + +The validation process originally exited when reviewer creation reached the +agent thread limit. Reviewer creation succeeds in the fresh repair session. +A bounded review then identified premature shared quota release after a +partial HTTP/1 response write: consuming 511 of 512 bytes retained the whole +buffer but charged only one byte, permitting an enclosing-budget sibling. +The regression's RED receipt is +`build/task180-on/recovery-regression-red-test.log`. + +Partial consumption now keeps the retained prefix charged. Complete drain +frees the buffer before returning capacity; a refill replaces and frees the +old buffer before returning its consumed prefix's capacity. The regression +verifies sibling refusal, refill bytes, complete release, and readmission. +The bounded closure review reports no remaining finding in this repair. +Recovery build and test receipts use the `recovery-repair-*` prefix in the +affected build directories; the earlier five-lane receipts above describe +the implementation before this follow-up repair. Follow-up normal TLS-on +passes six selected suites, including the slow-peer memory executable and +Python receipt checks; normal TLS-off passes four selected suites. TLS-on +ASan/nonrecovering UBSan passes the three repaired owner suites. All selected +suites pass with zero skips or errors. The resource suite now passes 20 cases +and 777 checks in each of these three lanes. The other sanitizer lanes were +not repeated during recovery. Changed C++ files pass cpplint and the diff +passes whitespace checks. Task completion, validation retry, and commits +remain runner-owned. + + +## Blocking validation repair, iteration 1 + +The initial validation audit identified two further allocation boundaries. +Coalesced bodyless H1 requests released parser residue's header charge without +admitting its new receive owner. The route path now reserves the existing +three-copy receive bound before copying or consuming residue, including when +all residue belongs to the next bodyless request. Seed assembly moves the +existing charged tail and prefixes the admitted residue; the bodyless tail +then takes the seed by move. One owning receive allocation remains through +handler suspension, and the regression compares its actual retained capacity +with the shared charge. Refusal emits the existing +413 close response before dispatch. Paused-handler regressions cover parent +and child bottlenecks, absent excess dispatch, exact ancestor usage, recycling +and restored sibling admission. + +Output reservations now cover each slot's retained string capacity, including +unused capacity. Before growth, a candidate reserves a geometric allocation +bound of `max(required_wire_bound, 2 * previous_capacity)` while the old buffer +remains charged. Its capacity is checked before publication; a candidate that +exceeds the bound is freed and refused. The old allocation is freed before its +reservation returns. Partial refill compacts and reuses charged storage; +complete drain frees it. Final-head serialization preserves any existing +interim allocation until acceptance, and rejection frees the candidate before +returning its charge. Interim, final, body, end and upgrade serialization all +use the same allocation admission. Upgrade output includes a queued interim +prefix in its allocation bound and accounts each emitted byte once. + +The primary RED receipt is +`build/task180-on/repair-iter1-red-test.log`: 24 cases, 821 checks and 16 +expected failures against the prior owners. A causal upgrade-after-interim +regression then produced three expected failures in +`build/task180-on/repair-iter1-upgrade-red-test.log`. Current TLS-on libraries +were rebuilt before the final focused checks. The final receipt is +`build/task180-on/repair-iter1-green-test.log`: eight passing gates, comprising +resource_limits, H1 parser, body mode/decoder/source, response outbox, +connection engine and the Python receipt contract. The resource suite now +passes 25 cases and 830 checks. All selected gates have zero skips or errors. + +Changed C++ paths pass cpplint and the diff passes whitespace checks. The +unchanged file-size violation remains `src/detail/io_poll_backend.cpp` at +509 SLOC; all changed library sources remain below 500. No configured capacity +or public API was changed. Other final lanes and closure reviews remain owned +by the coordinator; nonlocal platform checks remain assigned to CI. + +## Seed-publication closure repair, iteration 2 + +The bounded reader-interleaving probe found an ownership gap in iteration 1: +the route frame moved admitted residue out of engine-visible storage before +publication. A real reader absorb in that interval reduced an 81-byte charge +to 15 and publication discarded its byte, leaving 27 bytes instead of 28. +The body path similarly staged only the original prefix, leaving intervening +reader bytes behind. Assertion-enhanced RED receipts are +`build/task180-on/repair-iter2-seed-red.log` and +`build/task180-on/repair-iter2-body-red.log`. + +Head preparation now admits and prefixes residue directly into the +engine-owned pending tail under its mutex. Bodyless input stays in that owner; +body staging moves the entire tail into early storage while changing the gate +under the same mutex. Reader input therefore remains visible to receive quota +accounting and follows the seed in wire order throughout preparation. The +existing private fixture invokes the production preparation, absorb, staging +and recycle paths deterministically. Its regressions check exact bytes and +charges, retained-capacity coverage, body rejection and next-head recycling, +and reader refusal followed by owner release and capacity readmission. + +Current TLS-on libraries and the six focused executables were rebuilt before +`build/task180-on/repair-iter2-green-test.log`: resource_limits, +connection_engine, http1_body_source, http1_body_decoder, +http1_websocket_upgrade and websocket_drain_race all pass with zero skips, +failures or errors. The resource suite passes 28 cases and 855 checks. +Changed C++ files pass cpplint and the diff passes whitespace checks. The +settled outbox repair and public contracts are preserved. Final affected lanes +and closure review remain coordinator-owned; nonlocal checks remain with CI. diff --git a/docs/task-181-diagnostics.md b/docs/task-181-diagnostics.md new file mode 100644 index 000000000..91948f11b --- /dev/null +++ b/docs/task-181-diagnostics.md @@ -0,0 +1,109 @@ +# Bounded native diagnostics + +Install a shared diagnostic channel before constructing the server: + +```cpp +#include +#include + +httpserver::server::diagnostics channel([](const auto& event) { + // Consume library enums and scalar identifiers on this application's thread. +}); +httpserver::server::server_options options; +options.diagnostic_channel() = channel; +httpserver::server::native_server server(options); +// Configure routes/listeners and run the server as usual. +channel.dispatch(32); +auto counters = channel.counters(); +``` + +Call `dispatch()` regularly on an application thread to receive callbacks. +Each call consumes at most its requested maximum and the queue size observed +at entry.

Required ASan/UBSan lanes +enable LeakSanitizer, stack-use-after-return, stack-use-after-scope and +nonrecovering UBSan. Execute outside the ptrace sandbox, as in TASK-186/200. +Disabling required leak or stack checks fails the stage. TSan reuses +`test/tsan.supp`; only the existing WebSocket allocation fault injection and +timer-allocation reclaim hook are omitted because TSan owns operator new. +Public package/adapter execution can use `--isolated-public-network` to create +a loopback-only Linux user/network namespace for authentic ACME TCP443. +Bootstrap/distribution preparation stays outside that namespace: Automake +preserves root-owned system macro metadata when making the distribution. +The two excluded case names and reasons are checked and normal/ASan coverage +remains mandatory. Nonlocal backend suites are recorded +by name, separate from executed local cases. + +The existing source-only README/release-note/Doxygen checks require a Git +checkout with specifications. A verified specifications bundle supplied to an +archive for parity does not turn it into a checkout. Packaged `make check` +retains all native, header, example, lint, installation and hygiene checks; +the documentation checks retain their documented source-checkout scope. + +The release inventory requests `--optimized` from the installed-package builder, +selecting `CXXFLAGS=-O3 -g` for the production libraries used by protocol and +performance checks. The ordinary installed-consumer invocation retains its +existing default. Benchmark acceptance still requires optimized normal-allocator +artifacts and the full measured workload. + +The external-readiness test uses target-local linker wrapping on Linux/FreeBSD +to inject allocation failures before delegating successful allocations to the +real allocator. This preserves sanitizer allocator ownership. All five +allocation-failure cases remain active under TSan, with no additional exclusions. +The supporting normal, ASan/UBSan and TSan probes each pass 28 tests/497 checks; +full configured release proof remains separate from these probes. + +Simulator-clock verification binds the selected retained receipt path after +checking its artifacts and real immutable image. The producer worktree may +already be removed. Reopening the selected path must reproduce the same +validated configuration; the historical receipt bytes remain unchanged. + +The `artifact-identity.json` distinguishes packaged files from the same-snapshot +specification/documentation bundle needed by historical runners. Archive runners +verify both identities instead of manufacturing Git metadata. Normal private +fixtures remain supporting evidence. Shared libraries and every native archive +member must match installed production artifacts; installed consumers reject +source headers and undeclared dependencies. + +Before creating a release tag, verify the complete receipt set: + +```sh +python3 scripts/run-v3-release-gates.py \ + --check-tag-ready "$PWD/build/task185-release-01/manifest.json" +# Or: make check-v3-tag-ready RELEASE_GATE_MANIFEST=/absolute/manifest.json +``` + +This command fails closed on missing/failed required local gates, altered +artifacts, unapproved exclusions or pending platform receipts. The release +workflow starts after a tag exists; it does not itself enforce this pre-tag +prerequisite. Tag creation remains a separate release-owner action. + +The final continuation selects explicit pinned clients for nested package +checks, carries the verified simulator-clock compatibility receipt into the H3 +aggregate, and uses the full benchmark defaults: 4096 measured requests, +256 requested warmup requests, protocol-specific epochs, 1024-byte payloads, +four workers, H1/H2 concurrency eight, and H3 concurrency four. Reduced runs +cannot satisfy the independent benchmark validator. + +The public and benchmark envelopes also freeze the adapter catalogs, including +consumer executables, link maps and selected client modules retained outside +the stage directory. Nested JSON hashes alone do not replace those bytes. + +After the final stage, local completion independently rehashes every retained +gate envelope, source/archive/provider and selected executable even while +platform evidence is pending. Expanded package audits have a bounded 64 MiB +JSON limit; the TLS-on audit now exceeds the former 32 MiB bound. + +A packaged H1 runner contract copied a miniature source fixture while inheriting +the enclosing archive identity. Its isolated fixture now removes that unrelated +identity; real release invocations still require and verify the explicit archive +identity. The observed 1-versus-7 exit regression and corrected execution are +retained separately. + +The fresh source incorporates the completed TASK-200 dependency (`v3` at +`940b301dbdad2adf924e8b6981eefa983414365f`). Historical attempts remain unchanged. +The complete continuation inventory is retained in `build/task185-final-17`. +Seventeen mandatory local gates pass; the full native throughput/latency gate +fails on an actual H3 wire error. Local acceptance remains unsuccessful. +FreeBSD/macOS/Windows receipts remain pending and CI/v3-PR owned. + +## H3 response recovery (2026-10-14) + +The implement-step recovery reproduced the response truncation deterministically. +The wire owner checked the body queue while empty, then a native worker published +both payload and completion, and the owner observed completion and retained FIN +without the payload. The same schedule could emit trailers ahead of the body. +`stream_output` now observes completion before queue size: after completion is +published no producer can append, so FIN/trailers require a subsequently empty +queue. A false completion snapshot defers terminal output to the next owner turn. + +The native H3 regression enumerates mutex-release seams while a suspended handler +publishes a 1024-byte response, with and without trailers. Target-local linker +wrapping on Linux/FreeBSD forces the schedule without a production hook or sleeps. +The unchanged sender fails twice with an empty body; the repaired sender passes +all 14 tests/302 checks. The 11 affected native H3/QUIC suites pass 161 tests/2,601 +checks. Focused ASan/UBSan (including leak, stack-after-return and scope checks) +and TSan runs also pass the 14-test regression suite with the existing sanitizer +policies. These focused sanitizer binaries combine the repaired response object +with the retained instrumented core archives; they are supporting repair evidence, +not a replacement for fresh complete release lanes. Benchmark contracts pass 18 +tests. Evidence is retained separately under `build/task185-h3-repair`. + +The historical `task185-final-17` manifest remains unsuccessful and unchanged. +The full mandatory inventory must run again on a fresh archive through the +retried implement step. The task remains In Progress; validation, commits and +finalization remain runner-owned. Nonlocal checks remain CI/v3-PR owned. + +## Entropy gate recovery (2026-10-14) + +The fresh `task185-final-18` package matrix passed, then its TLS-off broad +check caught a statistical test defect: a one-byte OS draw legitimately equals +zero with probability 1/256. The entropy seam deliberately rejects all-zero +draws, while the old length test unconditionally expected success. A controlled +`getrandom` wrapper reproduces that failure deterministically without changing +the production entropy implementation. The repaired test checks the one-byte +outcome against the actual byte and verifies both adjacent guard bytes. It +retains the larger successful-fill, distinct-draw and batch checks. + +The controlled regression changes from four tests/18 checks with one failure to +five tests/21 checks passing; the real OS draw also passes. Evidence is retained +in `build/task185-h3-repair/entropy-repair-summary.json`. Attempt-18 and its failed +native transcript remain unchanged.

It occurred during warmup after +407 completed connection epochs, 1,628 measured responses and 1,628 warmup +responses, before the required 4,096 measured requests completed. The runner +correctly retains `local_passed=false` and `tag_ready=false`. The child failure +then terminates the consumer; its recorded exit -9 is teardown after the wire +failure, not an independent server-crash diagnosis. No workload reduction, +retry or successful aggregate is substituted for this observation. + +The blocked dependency is native H3 response/QUIC lifecycle correctness under +the full installed benchmark. The caller must assign causal repair ownership +across the TASK-195/196/198 component lineage. A repaired source must pass the +complete mandatory inventory before local acceptance can close. This task +remains In Progress; later validation, commits and finalization are caller-owned. + +Exact reproduction inputs are retained in +`build/task185-tool-recovery-15/final-17-invocation.json` and the task-local +`run-final-17.py` launcher. Tool receipts identify Clang 18.1.3, GNU Make 4.3, +Python 3.12.3, Node 24.15.0, h2spec 2.6.0, Go 1.25.1, Docker 29.1.3, +TShark 4.6.4, Autoconf 2.71, Automake 1.16.5, Libtool 2.4.7, OpenSSL 3.5.9 +for the selected provider, h2 4.4.1, aioquic 1.3.0 and websockets 15.0.1. +All selected executables, provider bytes, libraries, headers, logs, commands, +image identities and adapter catalogs are retained with hashes. Preserve the +attempt, retained stage copies, external consumer directories and selected +tool artifacts before any worktree cleanup; their receipt paths are absolute. + +The four setup repairs have observed RED/GREEN evidence in +`build/task185-tool-recovery-15`: documentation-bundle scope, optimized package +selection, simulator receipt retention and sanitizer allocator ownership. +Focused contracts pass: release runner 44, installed consumer 29, QUIC runner +36 (four existing optional retained-capture fixture skips), full H3 runner 27. +The external-readiness normal, ASan/UBSan and TSan probes each pass all 28 tests +and 497 checks, including all five allocation-failure cases. The fresh full +sanitizer inventory independently confirms their configured integration. + +## Historical implementation and unsuccessful attempts + +`build/task185-final-16` is a complete unsuccessful attempt with all 18 local +stage outcomes retained (nine passed, nine failed). Its manifest SHA-256 is +`d17f8912d8c6721bd0d34433bf60cc7473619d1f04cb62f60d50b5038f9e454d`. +It proves the installed public capability adapters and bounded fuzz executions +ran successfully. Remaining setup failures were the tooling-bundle documentation +guard, TSan allocator replacement, historical simulator receipt location, and +debug production-library selection for benchmarks. Each repair has focused +failing-then-passing evidence. It remains unsuccessful and supplies no complete +release acceptance claim for the repaired source. + +The following evidence describes earlier snapshots and their actual failures; +it does not establish acceptance for the repaired source. + +Validation recovery identified an integrity failure in the historical +`task185-release-05` package envelope: subsequent native builds changed configured +dependency files that the envelope had already hashed. Its original manifest +and hashes remain untouched. The reported package pass is historical execution +evidence, but that envelope no longer passes artifact verification and cannot +satisfy release readiness. + +The repaired runner retains independent byte copies under `retained/` +before proceeding to another stage. Receipt artifact paths and command log paths +refer to these copies; `retained_paths` and each command's `execution_log` preserve +the mapping to the executed paths. Copying checks the original size and SHA-256, +and any retention failure makes the stage unsuccessful. Configured build trees +remain available for later gates without invalidating earlier evidence. A +regression completes a package stage, runs a subsequent native build/check that +changes its dependency file, and re-verifies the original package receipt; it +also confirms that altering a retained copy fails verification. + +The pending-platform regression now begins with a complete verified manifest, +checks its successful positive control, and then requires the platform-specific +failure for missing and pending platform rows. Neither this repair nor focused +validation changes the mandatory inventory or supplies missing public integration +and benchmark capabilities. The all-local-gates criterion remains unsuccessful. + +Recovery execution is retained in `build/task185-recovery-summary.json`: + +The fresh repair-session recheck is retained separately in +`build/task185-recovery-recheck-03/summary.json`. Its 32 runner and seven archive +contracts pass, and the immutable package envelope re-verifies. The installed +TLS-on static consumer using OpenSSL 3.5.9 still emits `not_supported unbound` +for public TLS, HTTP/2 and HTTP/3 listener configurations. The relevant server +implementation, public server header and native test inventory match the verified +package source byte-for-byte. Repeating the release readiness check still fails +on unsuccessful mandatory local gates. No historical receipt was rewritten. +This confirms the missing product/benchmark dependencies; setup repair alone +cannot supply the capabilities explicitly excluded by the selected task plan. + +| Recovery evidence | Verified result | +| --- | --- | +| `build/task185-recovery-01` | Fresh packaged TLS-off/on matrix: 830 tests, 14,677 checks; normal native resource stage: 44 tests, 871 checks. | +| Retained package envelope after native builds/checks | Verification passes despite 19 changed files in the working package build trees. | +| `build/task185-recovery-focused-02` | Final packaged runner/archive contracts: 32 + 7 tests; two registered Automake script suites pass. | + +The first package probe predates the final conflicting-record regression; the +focused distribution includes that final guard. They are separate snapshots, +neither a complete passing release inventory. Initial registration probes +mistakenly triggered native-program prerequisites; their failure logs remain +retained. The corrected focused registration command is +`make -C /test check-TESTS check_PROGRAMS= 'TESTS=integ/release_gate_runner_test.py integ/release_artifact_test.py'`. +Working-tree release/archive contracts also pass all 39 tests; affected H3, +installed-consumer and package-workflow contracts pass 26, 24 and four tests. +Warning-suppression lint, fence contracts, Python compilation and diff whitespace +checks pass. The existing 509-SLOC backend file-size failure is unchanged. + +The selected task plan explicitly excludes implementation of missing public +protocol capabilities and native benchmarks. The remaining mandatory acceptance +failure requires a scope decision or delivery by those dependency owners. The +repair leaves TASK-185 In Progress and preserves all required gates, failed +historical receipts, and CI ownership of nonlocal checks. No commit, merge, tag, +push or deployment is performed in the recovery session. + +The task-local Linux execution selects the static OpenSSL 3.5.9 provider at +`/home/etr/progs/libhttpserver/build/tooling/provider`, allowing the existing +QUIC endpoint image to carry the same provider code in its executable. The +installed package matrix still tests both shared and static libhttpserver +linkage. The separate shared-provider package attempt is retained independently. + +Each native Automake test has a 180-second deadline through the selected GNU +`timeout` tool, with a five-second kill grace. Build commands retain their own +longer deadlines. A timed-out native test fails its gate; other native tests and +independent release stages continue. An existing Linux `peer_policy` test stalled +in `concurrent_mutation_and_reads`. Its six unbounded readers and two mutators +suggest reader starvation; the retained log alone does not establish the cause. +Its first eight cases passed in that log. +That product/test dependency is owned by peer-policy maintainers through +ownership triage; this task retains the failure rather than changing the test +or library policy. + +`--tool-artifact PATH` binds wrapper runtime dependencies and capture libraries +to the receipt in addition to the selected tool executable hashes. The local +capture runtime comes from the existing `task163-runner-tools` Docker image; +its loader/libraries and Compose executable are declared artifacts. Go 1.25.1 +and Node 24.15.0 downloads were checked against official checksum metadata. +Python packages, h2spec's exact build identity and tool versions are retained in +the command logs. Tool provisioning is a separate task-local setup step; the +release runner itself never downloads tools or modifies host package policy. + +When CI platform evidence returns, retain its referenced artifact files and +supply matching platform envelopes to the verification command: + +```sh +python3 scripts/run-v3-release-gates.py --check-tag-ready /absolute/manifest.json \ + --platform-receipt /evidence/freebsd.json \ + --platform-receipt /evidence/macos.json \ + --platform-receipt /evidence/windows.json +``` + +Platform identities must match the same archive, source snapshot and extracted +file set. Importing platform evidence preserves the original local receipt. +Missing, duplicate, altered, failed or differently sourced evidence fails. + +| Attempt | Retained outcome | +| --- | --- | +| `build/task185-release-01` | Preparation rejected the existing `AC_CONFIG_FILES` fixture's terminal newline; the precise transformation now has a RED/GREEN contract and retained source/package hashes. | +| `build/task185-release-02` | Preparation passed; stage verification rejected the missing process-global identity variable. The corrected adapter accepts an explicit verified identity path, covered by RED/GREEN contracts. | +| `build/task185-release-03` | Shared-provider installed matrix passed. The full native check stalled in `peer_policy`; the superseded attempt was interrupted, preserving its snapshots, test logs and command records. | +| `build/task185-release-04` | Superseded during package execution after adding the tested native-test deadline. Logs and the exact source/archive identities remain retained. | +| `build/task185-release-05` | Complete inventory execution with pinned clients, static provider, capture runtime and per-test deadlines; final results are recorded below. | + +The frozen full attempt was retained when real stdout formats exposed receipt +adapter defects: normal allocator windows and the private rotation example do +not emit Littletest summaries, Automake aligns its counts, and H2/H3 resume +probes use different payload sizes. Each correction has a failing-then-passing +contract. The current runner also copies native `.log`/`.trs` details into stage +evidence on failure. H1 archive logging now verifies the supplied archive +identity rather than discovering Git metadata from an enclosing checkout. + +These corrections do not promote the original failed aggregate. Supplementary +receipts verify the unchanged attempt-05 archive, source, executables and +installed archive members; their exact adapter copies/hashes are retained. +`build/task185-adapter-audit-05-v2/receipt.json` rechecks the successful TLS and +slow-peer executions. `build/task185-supplement-05/manifest.json` contains fresh +normal allocator and installed-example probes. Independent WebSocket execution +still fails in that supplement. + +The fresh `build/task185-current-08` distribution includes the normalizer's +previously omitted `data/normalize_body_fixture`. The existing packaged test +first failed its body-file expectation; with the fixture distributed it passes +11 tests/30 checks. Its packaged release contracts pass 28 runner tests and seven +archive tests. Final working-tree contracts also pass all 35 tests. Cosmetic +refactoring and subsequent reporting edits are separate from each recorded +archive snapshot; historical receipts cannot satisfy a different archive. + +| Supporting evidence | Exact successful counts | +| --- | --- | +| TLS-off/on installed shared/static package matrix | 830 tests, 14,677 checks | +| Independent H2/h2spec receipt | 155 successful cases; pinned exclusion inventory retained separately | +| Private TLS/policy/ACME/PSK/QUIC/rotation executions, corrected adapter | 155 tests, 4,085 checks | +| Normal allocator H1/WS CPU/RSS windows and resource reservations | 44 tests, 871 checks | +| Normal allocator H2/H3 slow peers, uploads, cancellation and resume | 12 measured idle windows; three download and three upload cycles per protocol | +| Installed examples outside the failed full native check | Four TLS-off and four TLS-on compilations | +| Packaged normalizer fixture regression | 11 tests, 30 checks | +| H3 TLS-off native and ASan/UBSan derivatives | 48 suites per derivative: 431 Littletest tests/12,270 checks plus 110 named corpus cases | +| H3 TLS-on native and ASan/UBSan derivatives | 55 suites per derivative: 497 Littletest tests/13,501 checks plus 110 named corpus cases | +| Independent QUIC transport matrix | 12 successful peer/case cells, 36 validated captures and two authenticated closure witnesses | +| Independent RFC 9220 WebSocket supplement | 11 successful client cases | + +The normal TLS-off broad check reports 215 suites: 209 pass, four fail and two +nonlocal backend skips. The failures are the missing packaged normalizer fixture +(fixed in the later distribution), the `peer_policy` deadline, six failing H2 +engine checks, and the raw WebSocket handshake client. The independent +WebSocket lane also times out waiting for the `/flood` handshake. The parity +inventory requests `cookie_render`, which has no target in the current v3 +Makefile; its missing per-case evidence remains unsuccessful. + +The fresh ASan/UBSan TLS-off check reports 215 suites: 207 pass, six fail and two +nonlocal backend skips. Besides normalization, H2 and WebSocket failures, ASan +reports stack-use-after-scope in `consumer_v3_concurrency` +(`resume_signal.hpp:393`), `response_sources` (`body_sink_fake.hpp:121`) and +`forms_multipart_route` (`forms_multipart.cpp:276`).

The +C++20 package builds and focused implementation checks pass. Full release/tag +readiness remains false; no tag or publication is performed by this runner. + +The normal TLS-on broad check reports 243 suites: 237 pass, four fail and two +nonlocal backend skips. The ASan/UBSan TLS-on check reports 243 suites: 235 pass, +six fail and two nonlocal backend skips. Their failed suites match the respective +TLS-off inventories. Both TSan builds fail at `task_resume_signal_lifetime`: +its global `operator new/delete` definitions conflict with the TSan runtime. +No executed TSan owner-suite pass or allocation-exception coverage is claimed. + +The C++20 configuration adapter also needed to recognize Autoconf's actual +`CXX = clang++ -std=c++20` value when `CXXFLAGS` contains optimization/debug +flags. Its RED/GREEN regression retains compiler, Automake and user flags, +still rejects missing standards and uninstrumented sanitizer configurations, +and passes 26 existing/new full-H3 contracts. The fresh +`build/task185-h3-supplement-05` execution uses exact copied adapter files from +`build/task185-h3-supplement-adapter` over the verified attempt-05 source/builds; +it does not replace the failed frozen aggregate. +All four native derivatives and the QUIC transport matrix pass in that +supplement. The aioquic semantic client completes, but the quic-go fixture +reports `drain deadline expired`; the unchanged runner then rejects its shutdown +`traffic` event while waiting for required semantic completion. Its H3 aggregate +fails before the later WebSocket/fuzz stages. The independent +`build/task185-h3-ws-supplement-05` lane executes the same required RFC 9220 +predicate successfully instead of treating the skipped aggregate stage as a +pass. The outer release inventory executes its separate instrumented fuzz lanes. + +The complete attempt-05 archive SHA-256 is +`da82a11660bc5c2444df89d9023e4eb9c99948ca33b6280213d7b033d65a6668`; +its source snapshot SHA-256 is +`6a0bcd677c13ec2b799c9124f4a79e17bf625a36c0c53d9134caa080389dfeee`. +The current-08 focused archive SHA-256 is +`4d804a577ac377796fa54e82693c8d544363b265d00c4a826e5673703ac0ee3c`; +its source snapshot SHA-256 is +`c61e94913bb1347471840a730625a5b4eeb98e8e5967df8149b41febbbf5c7e7`. +Later documentation/tracking edits are outside those frozen snapshots. + +| Recorded local tool | Version | +| --- | --- | +| Clang C/C++ | 18.1.3 | +| GNU Make / Autoconf / Automake / Libtool | 4.3 / 2.71 / 1.16.5 / 2.4.7 | +| Python / h2 / aioquic / websockets | 3.12.3 / 4.4.1 / 1.3.0 / 15.0.1 | +| Node / Go / quic-go | 24.15.0 / 1.25.1 / v0.55.0 | +| h2spec | 2.6.0, build `70ac2294010887f48b18e2d64f5cccd48421fad1` | +| Docker / Compose | 29.1.3 / 2.40.3 | +| tshark / editcap | 4.6.4 / 4.6.4 | +| Static OpenSSL provider | 3.5.9 | +| pkg-config / GNU timeout / Binutils / glibc | 1.8.1 / 9.4 / 2.42 / 2.39 | +| Upstream QUIC runner | `740c05a10b61d65e8abd3ad38d60898004d335d9` | + +`/tmp/task185-final-run.py` retains the exact full-inventory launcher and +`/tmp/task185-h3-supplement.py` retains the bounded full-H3 supplement launcher. +Tool versions, binary hashes, environments and runtime closures are additionally +retained in the manifests and command logs.

WebSocket uses HTTP/1.1 Upgrade (101 and +Accept); public H2/H3 listeners use Extended CONNECT (200 without those fields). +HTTP/1.0 WebSocket and cleartext certificate/TLS cells are protocol applicability +exclusions, not failed parity observations. + +Native TLS selects optional OpenSSL at build time with `--enable-v3-tls`; the +current build gate requires stable OpenSSL **3.5.x patch 9 or later** and its QUIC +TLS callbacks. Public certificate values go through `server::tls_credentials`; +`listener_options::credentials` associates the store. `server_options::tls()` +selects provider/profile policy. Public host values accept initial mTLS trust and +request/require mode, or bounded external PSK for HTTP/1. The application owns the +shared lookup runtime through actual callback retirement; server stop requests +cancellation without joining application code. Public ACME publication/removal +uses application-supplied material and exact SNI/sole `acme-tls/1` on TCP443. +Post-handshake auth remains unavailable; see the [public TLS lifetime contract](native-tls-build.md). + +The [public listener rotation example](../test/examples/tls_rotation.cpp) +uses `server::tls_credentials::replace()`: successful publication replaces the +active generation, accepted sessions retain their contexts, and failed +replacement leaves the active publication unchanged.

Each nonlocal producer checks the exact selected archive against its +checkout, runs the complete installed and native TLS-off/on suites, validates +raw results and exports a platform bundle. The Linux job then executes all 18 +existing local gates against that same selected archive. Full H3 interop, +sanitizers, installed public capabilities and full benchmark workloads retain +their existing acceptance rules and exclusions. + +The fixed FreeBSD/Darwin/Windows bundles preserve original receipt bytes and +logical artifact paths.

Import checks +safe extraction, namespace uniqueness, every catalog hash and referenced +package input; it reruns the installed matrix, raw-suite/count and native-result +validators. Windows path normalization applies only to logical lookup and +comparison; foreign binaries are never executed. Sealed dyld/API-set OS leaves retain the +existing auditor’s explicit whitelist; nonexistent OS files are never +synthesized. Missing/changed bytes, +missing native replays, failed suites and stale counts block readiness. + +Linux evidence stays on its original filesystem. The actual `check_tag_ready` +validator checks all 18 local gates and all three platform receipts before an +authorization is written. That authorization binds the repository, workflow +source/run/attempt, selected commit/tag/archive, accepted manifest and immutable +selected/platform artifact IDs and digests. Downloads compare the actual ZIP +SHA-256 with both producer output and GitHub artifact metadata; a warning from +a download action is insufficient. Artifact creation must belong to the current +run attempt; rerun all jobs to produce fresh release proof rather than reusing +artifacts from successful jobs in an earlier attempt. + +On PR runs, artifact/run API metadata identifies the PR branch head, while +`GITHUB_SHA` and the selected checkout identify the test merge commit. Downloads +bind the API head to the trusted event's PR head. Selected archive preparation +and platform proof still require the exact selected checkout commit, source +snapshot and archive bytes; these two source identities are not interchangeable. + +The final publisher alone receives `contents: write`. It checks successful +mandatory dependencies, same-run artifacts, manifest and archive hashes and the +current tag target before `gh release create --verify-tag`. It runs only inline +workflow code and the GitHub CLI, with no checkout or downloaded candidate code. +Historical release sources retain their legacy distribution validation path. +The workflow starts after an existing tag; release owners must still execute +the separate pre-tag readiness command. This is publication enforcement. + +PR and validation-only dispatch use the same archive, platform and full local +path, and cannot publish. For an explicit manual validation request, provide an +already resolved 40-hex `source_commit` and its `source_version`.

Defaults remain +4096 measured requests, 256 warmup requests (protocol epochs may increase +warmup), 1024-byte payloads, four workers, H1/H2 concurrency eight, H3 concurrency +four, and a 300-second client deadline. `--requests 16 --warmup 4` is reduced +integration evidence. It cannot satisfy `--require-full-workload`. + +To validate in a new process, use the same selected inputs, workload and run ID +with `--validate NEW_OUTPUT/receipt.json`. Validation rehashes the archive, +extraction, build, installation, provider, tools and Python client modules. It +reads evidence without modifying it. For full benchmark release proof add +`--require-full-workload`; TASK-185 must also apply its existing release gates. + +## Receipt schema and retained artifacts + +The outer JSON receipt has `schema_version=1`, `family`, `status`, `run_id`, +`identity`, `inventory`, `inventory_sha256`, `children`, `full_workload`, +`artifact_roots`, `artifact_extras`, `artifacts` and `nonlocal_checks`. Failed +attempts retain `status=failed` and `error` and cannot pass validation. + +`identity` binds the archive digest and every regular distributed source member, +source/build/install paths, installed header/library/pkg-config hashes, +configuration hashes, provider files, executable hashes, pinned client versions +and module hashes, and workload. Archive paths must be safe, consistent, +unique and regular files/directories; symlink/hardlink members are rejected. +A genuine extraction needs no `.git` directory. + +`identity.darwin_sdk` is an optional internal version-1 compiler context, captured +by `identity()` **before** consumers compile and reverified after execution and +on validation. On Darwin, the literal configured CXX argv is queried with +`-### -x c++ -c /dev/null -o /dev/null`, without a shell or target-code execution. +Exactly one macOS `-cc1` job must select one absolute `-isysroot`. Only that +canonical SDK's direct, nonsymlink `SDKSettings.json` can supply this exception; +other SDK files, sibling JSON, caller paths, and matching hashes grant none. +Unsupported, failed, indirect response/config/VFS, missing-SDK and ambiguous +queries yield no context. They never relax dependency admission. + +The optional object contains `version=1`, literal `compiler_argv`, `environment`, +canonical `sdk`, effective `target`, `driver` artifact, `compiler_inputs` artifact +mapping, `metadata` artifact, `metadata_hex`, and `query`/`query_sha256`. +`compiler_inputs` binds the selected executable and existing regular file argv +operands (including a quoted compound CXX wrapper). Artifact records use the +existing absolute `path`, `bytes`, `sha256` contract. `metadata_hex` retains the +actual bounded metadata bytes in the exported identity; it is not a path/hash +claim alone. The original live metadata, driver and compiler inputs must also be +selected by `identity_artifacts()` and included in the artifact catalog. +`query` retains literal argv, cwd, exit, stdout and stderr, with a canonical JSON +SHA-256 association. Revalidation independently rederives selection using the +configured compiler. It compares selected inputs, target, argv, environment and +bytes; varying query diagnostics are retained and checked without becoming a +false identity difference. + +Selection environment capture includes SDKROOT, DEVELOPER_DIR, TOOLCHAINS, PATH, +Apple deployment targets, CCC_OVERRIDE_OPTIONS, Clang config selectors, compiler +search paths and language include paths (the exact keys are `SELECTION_ENV` in +`compiler_sdk.py`). Actual compile logs must contain every key, including absent +values, and match the captured selection environment and literal CXX prefix. +The configured prefix is requeried in each actual compile cwd to catch relative +wrapper/SDK/search selection changes. Additional flags are restricted to the +existing public C++20 compile operations: include paths, definitions, ordinary +optimization/debug/warning flags and the supported sanitizers. Unknown options, +target/sysroot changes, response/config files, forwarding options and VFS +changes outside that prefix fail. The selected compiler/wrapper and command +logger remain trusted tools; this does not attest a malicious compiler or prove +that files never changed transiently between observations. + +All source/build/private contamination, public source/header, actual compile, +raw depfile/hash, link and static-contribution requirements still apply. Raw +SDK dependency paths and hashes are preserved, including canonical aliases; +metadata symlinks escaping the selected SDK fail. SDK-free legacy identities +and receipts retain their original strict checks. An absent precompile context +cannot borrow a newly discovered validation context: SDK-bearing legacy +receipts still fail as foreign dependencies. The schema version and existing +entry points remain unchanged. Native Darwin compatibility remains CI/v3-PR +owned; portable fixtures and a local Clang Darwin-target driver dry run provide +logic evidence only. Normal code revert is the rollback for this receipt-model +change. + +`children` maps the exact family members to receipt artifact records. Every +artifact record contains absolute `path`, `bytes` and `sha256`. The complete +catalog covers child receipts, command outputs, process receipts, copied +consumers/fixtures/client code, objects, depfiles, link maps, executable files +and benchmark raw samples. Compilation must use installed public headers, +C++20, and archive-distributed copied sources. Private headers, source/build +includes and `HTTPSERVER_COMPILATION` cannot supply public proof. Every cell must retain its family's compile and dependency records, including +H1 WebSocket, TLS profile/rotation, and H2/H3 example consumers where applicable. +Static link maps must show contributing members from the selected installed +archive and no foreign libhttpserver archive contribution; an unused LOAD entry +cannot supply proof. Shared runtime inspection must resolve the selected +installation. The first readiness line must contain at least one valid bound +port. Readiness alone cannot +supply response proof. Child inventories and decoded lifecycle/semantic +observations remain subject to their original validators. + +H1 validation requires exact HTTP/1.0 or HTTP/1.1 response prefixes and exactly +two recorded persistent and pipelined responses. WebSocket peer-close evidence +records actual pending receive entry, completion with the public +`connection_closed` outcome, and handler retirement before server stop. The +legacy `cancelled_receive` count represents this observed transport termination; +it does not assert an `outcome_code::cancelled` result. TLS profile rows retain +and validate positive and negative authentication, handler deltas, decoded +responses, callback cancellation/retirement, SNI generations, session rotation, +and applicable ACME observations independently of their scenario names. + +TLS authentication rejection controls retain the independent provider client's +exit 2 only with a decoded `connected=false` handshake and the exact bounded +client argument shape. The explicit peer-close cancellation control retains its +intentional killed-client terminal. These controls cannot supply a successful +protocol exchange; positive clients and server cleanup must exit zero. + +Keep the archive, extraction, builds, installs, provider, clients, output roots +and recorded external consumer directories available for revalidation. Catalog +pruning, deleted provenance, changed process output, altered samples/statistics, +reused run IDs and different expected package/archive identities fail.

The +ledger range is7..65,536; its actual prepaid storage can impose a smaller limit. +Explicit H3 policy needs at least four aggregate stream seats for three peer +critical roles and one request. Uni credit8 also permits unknown stream types; +those records compete with requests and terminal records for the same ledger. + +Header bytes and fields must be positive. H2 expanded bytes fit three copies in +`header_bytes`; H3 needs five aggregate header-byte charges and an additional +semantic field seat (`max_fields + 1`). Field resource maxima are65,536 for H2 +and65,535 for H3, subject to the configured budget. H2 compressed bytes fit the +body-buffer budget after native owner, frame and one stream descriptor workspace. H3 compressed/decoded metadata, retained HEADERS, semantic +copies, body/response buffers and descriptor arrays must fit its private prepaid +workspace. At least one maximum compressed section must fit retained HEADERS. +All arithmetic and wire conversions are checked; errors identify the field or +storage/budget relationship. Explicit values are rejected instead of clamped. + +Compression tables permit zero, with a resource maximum16,777,216 bytes. Both +local directions must fit the same aggregate compression budget for an explicit +policy.

See +[RFC9204 §§3.2.3,5,7.3](https://www.rfc-editor.org/rfc/rfc9204.html). + +Private H3 data/critical subdivisions grow for explicit policy when the root +reassembly budget permits.

H2 advertises the resolved +request/decoder ceilings; H3 advertises its decoder/blocked ceilings and QUIC +advertises initial request credit. Neither protocol advertises a header-list or +field-section byte maximum. `max_header_list_bytes` and +`max_field_section_bytes` remain absent even with explicit local header limits. +Expanded size includes name/value bytes and32 bytes per field, as described in +[RFC9114 §4.2.2](https://www.rfc-editor.org/rfc/rfc9114.html#section-4.2.2). + +Normal request retirement replenishes QUIC MAX_STREAMS credit.

Full matches run before prefixes; full-tier +siblings use registration order, and prefixes choose greatest depth then +registration order. Register literals before captures. Custom methods are +normalized to uppercase (`custom` also works); v2 regex routes are absent. +`/throw` produces a sanitized 500. `/throw-committed` closes the exchange without +a replacement response. `/stop` initiates cancellation; its caller has no +promised reply. + +### Request values and cookies + +```sh +./examples/request_data 30 +curl -i -H 'X-Repeat: first' -H 'X-Repeat: second' \ + -H 'Cookie: a=1; a=2' -H 'Cookie: b=3' \ + "http://127.0.0.1:$PORT/inspect?a=one&a=two+words&encoded=%2F" +``` + +Observe the unchanged encoded target, separate route path, ordered repeated +fields/cookies/query pairs and two separate Set-Cookie fields. Only the query +substring is decoded, under 256 bytes/8 fields. Malformed `%` gives 400; excess +query bytes/fields give 413. Startup also checks field append/replacement/first/ +all/entry order and invalid cookie rendering preserving its output string. + +### Incremental bodies + +```sh +./examples/body_streaming 30 +curl -i -H 'Expect: 100-continue' --data-binary hello "http://127.0.0.1:$PORT/reject" +curl -i --data-binary hello "http://127.0.0.1:$PORT/upload" +curl -i --raw "http://127.0.0.1:$PORT/download" +``` + +Observe refusal before body admission, `bytes=5`, and 64 bounded generated +chunks followed by ordered `X-End` trailers. `/download/slow` streams a fixed +4 MiB payload from one 32 KiB buffer, with startup/finish-accepted handshakes +for a slow reader smoke. Its explicit 16 MiB output budget includes retained +allocation and bounded growth scratch; finish acceptance is not peer receipt. Upload uses a fixed 64-byte buffer +and explicitly enforces a 1024-byte total cap; admission's buffering policy is +not a total streaming byte limit. Completed request trailers are inspected +only after EOF. `start_response()` closes the body reader: consume uploads +before responding; this API does not demonstrate simultaneous duplex bodies. +Writer failures retire the coroutine without attempting another response. + +### Authentication + +```sh +./examples/auth 30 +curl -i "http://127.0.0.1:$PORT/auth/basic" +curl -i -u demo:secret "http://127.0.0.1:$PORT/auth/basic" +curl -i --digest -u demo:secret "http://127.0.0.1:$PORT/auth/digest" +curl -i "http://127.0.0.1:$PORT/public" +``` + +Missing/wrong credentials receive 401 challenges; correct demonstration +credentials receive `authenticated`. Digest uses SHA-256 and the library's +nonce/replay ledger. `/public` remains accessible. Basic requires TLS for +credential confidentiality; plaintext loopback here is a local demonstration. + +### Forms and uploads + +```sh +UPLOADS=$(mktemp -d) +./examples/forms "$UPLOADS" 30 +curl -i --data 'a=one&a=two+words' "http://127.0.0.1:$PORT/form" +curl -i --data 'a=one&a=two+words' "http://127.0.0.1:$PORT/form/read" +printf abc > /tmp/safe.txt +curl -i -F 'note=one' -F 'note=two' -F 'file=@/tmp/safe.txt' \ + "http://127.0.0.1:$PORT/multipart" +``` + +Both URL-encoded shapes preserve repeats (1024 bytes/8 fields); malformed +encoding gives 400 and excess bytes give 413. Multipart explicitly limits +4096 body bytes, 8 parts, 1024 bytes/part, 512 header bytes/part. Responses +show ordered text fields and sanitized filename/size without absolute paths. +The sink and exchange remain alive through the awaited reader. Partial files +are removed on abort; completed files are removed before replying by default. +`/multipart/keep` deliberately retains a completed `safe.txt`; the application +then owns/removes it. Files use random storage names independent of their +client filenames, so later uploads with the same client name leave retained +files intact. Use a private application-supplied upload directory. + +### Response sources and ownership + +```sh +printf 'reopened\n' > /tmp/v3-body.txt +./examples/response_sources /tmp/v3-body.txt 30 +for kind in bytes borrowed reopen factory file pipe missing closes; do + curl -i "http://127.0.0.1:$PORT/$kind" +done +curl -i "http://127.0.0.1:$PORT/file" +curl -i "http://127.0.0.1:$PORT/pipe" +``` + +Observe independent reusable bodies, per-send `X-Send` overlays, factory/pipe +trailers, an owned file starting at its transferred position, and a prefilled +pipe ending at EOF. Later file/pipe attempts become intentional precommit 409; +`/closes` shows exactly-once release. `/missing` deliberately maps checked +precommit failure to 404. Invalid empty leases are checked at startup. + +A lease owns the **actual immutable span storage**. Definition and exchange +outlive `send_definition`; each concurrent factory call creates a fresh mutable +producer and its spans survive until its next pull. Handle claims are +nonrefundable, including failed preparation. Pipes must reach EOF or declare +coherent bounded framing. File/pipe reads and producer pulls are synchronous +application work, not asynchronous file I/O. The `/icy` route observes the literal ICY status flag on H1 +via `status::with_shoutcast()`; it does not implement an audio subsystem. + +### Operations and lifecycle + +```sh +./examples/operations +curl -i "http://127.0.0.1:$PORT/short" +curl -i "http://127.0.0.1:$PORT/peer" +curl -i "http://127.0.0.1:$PORT/throw" +# Host stdin: stats, deny-loopback, allow-loopback, stop +./examples/lifecycle +curl -i "http://127.0.0.1:$PORT/wait" +# Host prints PENDING; enter resume to complete it, or drain then wait. +``` + +Operations retains all eight hook handles, short-circuits `/short` to 202, +adds `X-Hook: after`, observes exception/completion/status, and prints dispatched +diagnostic counts/gauges from `stats`. Connection cap is four; header and +response queues are bounded. `/peer` reports transport identity, independent +of forwarded headers. `deny-loopback` applies to subsequent keepalive requests; +restore access with stdin `allow-loopback`. Hooks perform no blocking I/O and +never log credentials/bodies. Close clients before observing active gauges; +retirement is asynchronous. + +Lifecycle creates fresh one-shot signals per `/wait`, keeps only copied +signals in a synchronized registry, and prints `RETIRED` on RAII cleanup. +`/timeout` returns 408 after 50 ms; disconnecting `/cancel` prints `CANCELLED` +and retires its frame. POST `/stop` demonstrates handler-safe stop. `drain` +initiates a 500 ms budget, `resume` can release accepted work, and `wait` is the +coordinator's blocking ticket observation (`completed` or `deadline_expired`). +No detached application threads or retained exchange pointers are used. + +### Protocols, external ownership and WebSocket + +```sh +./examples/protocol_options # TLS-off +./examples/protocol_options CHAIN_PEM KEY_PEM # TLS-on +./examples/external_event_loop 30 +curl -i "http://127.0.0.1:$PORT/hello" +./examples/websocket_echo 30 +curl -i "http://127.0.0.1:$PORT/echo" # refusal without Upgrade +``` + +Protocol options prints actual validation/listen outcomes and ports, then +stops. The external host accepts an optional positive duration (the command above +uses 30 seconds); without it the process remains running until signaled. It +is the canonical readiness example: snapshot +interests carry generations, the host waits on descriptors/wakeups/deadlines, +and dispatches readiness through the public driver while owning the loop. +H1 `/echo` accepts text/binary WebSocket frames, awaits writable under +backpressure, and keeps the session alive through bounded close notification. +Choose application origin/subprotocol/size policies before exposing it. + +For TLS programs supply a chain (leaf plus intermediates) and matching key for +`a.example`; trust roots belong to clients. From the configured TLS build: + +```sh +./examples/http2 CHAIN_PEM KEY_PEM +# Set PORT to its first numeric stdout line. Enter stop/EOF to finish. +curl --cacert ROOT_PEM --resolve "a.example:$PORT:127.0.0.1" \ + --http2 "https://a.example:$PORT/hello" +./examples/http3 CHAIN_PEM KEY_PEM external +# First line: UDP port. Second: TCP_PORT . Enter stop/EOF to finish. +``` + +H2 `/hello` returns `hello h2`; H3 `/hello` returns `hello native h3` and +`x-end: native-fin`. H3's TCP listener also serves H1/H2. Use `managed` or +`external`. Both protocols expose `/ws/echo` via Extended CONNECT and require +`harness.v1`. A curl build may lack HTTP/2 or HTTP/3; the focused independent +clients below cover Extended CONNECT/trailers without assuming curl support: + +```sh +# From the repository root, create a dedicated client environment: +python3 -m venv /tmp/v3-example-clients +/tmp/v3-example-clients/bin/pip install -r test/integ/http2-client-requirements.txt \ + -r test/integ/http3-client-requirements.txt +V3_EXAMPLES_DIR="$PWD/build/native-tls/examples" V3_TLS_MODE=yes \ + /tmp/v3-example-clients/bin/python test/integ/examples_test.py \ + ExampleTests.test_http2_hello_and_extended_connect \ + ExampleTests.test_http3_hello_trailers_and_extended_connect_both_loops +``` + +The smoke runner starts/stops bounded children and verifies supplied repository +test CA material; those credentials are test fixtures, not deployment keys. +Missing optional protocol clients are explicitly skipped. + +### TLS profiles and rotation + +```sh +./examples/tls_profiles certificate A_CHAIN A_KEY B_CHAIN B_KEY +./examples/tls_profiles mtls CHAIN KEY CLIENT_ROOTS require +./examples/tls_profiles psk identity HEX_KEY +./examples/tls_profiles acme CHAIN KEY CHALLENGE_CERT CHALLENGE_KEY HEX_DIGEST +# All print PORT=...; enter stop. ACME stdin: publish, invalid, remove, stop. +``` + +Certificate mode explicitly selects host A by default and B through exact SNI. +Use hostname-verifying `curl --cacert ROOT_PEM --resolve ...` against `/hello`; +for mTLS add `--cert CLIENT_CHAIN --key CLIENT_KEY`. `request` also works in +place of `require`; `/hello` reports authenticated client metadata as +`verified=0|1`. PSK is HTTP/1-only: the bounded runtime rejects unknown identity, +checks callback cancellation/deadlines/identity/key caps, owns callback captures +through retirement; the coordinator explicitly requests stop and waits for +retirement. A +TLS1.2 independent client uses the same `HEX_KEY` and identity (PSK authenticates +through the shared key rather than an X.509 trust root): + +```sh +printf 'GET /hello HTTP/1.1\r\nHost: a.example\r\nConnection: close\r\n\r\n' | \ + openssl s_client -connect "127.0.0.1:$PORT" -servername a.example \ + -tls1_2 -cipher PSK-AES128-GCM-SHA256 -psk_identity identity -psk "$HEX_KEY" -quiet +``` + +ACME receives application-supplied challenge material; the library does not +issue certificates. `HEX_DIGEST` is the 32-byte key-authorization SHA-256 digest +encoded as 64 hex digits and must match the challenge certificate's critical +`acmeIdentifier` extension. Expiration is one hour. `publish` validates before +publication; `invalid` preserves ordinary credentials; `remove` clears it. +Ephemeral ports prove publication/removal and **nonselection**. Actual selection +requires authentic TCP443, exact SNI and sole `acme-tls/1`; optionally append +`443` to the ACME server command on a host permitted to bind it, then run: + +```sh +openssl s_client -connect 127.0.0.1:443 -servername a.example \ + -alpn acme-tls/1 -showcerts + +#include +#include + +#include "./example_host.hpp" +#include "./example_reply.hpp" +namespace http = httpserver::http;

The authorized rerun recorded +`max_cmd_len=786432`; no source change was made for that environment issue. +The overloaded intermediate two-job test build was interrupted through its +inspected task-owned make supervisor; its receipt is retained. +Final native and test builds run serially; subsequent supervisors use +`nice -n15`, `-j1`, and no overlapping build/test/client/sanitizer workloads. + +The initial `make check -j1` in `final-full-check.log` **failed**: +218 total, 217 pass, 0 skip, 1 fail, 0 error. Ordinary HTTP +`eof_before_request_closes` hit its unchanged ten-second bound. An isolated +original engine replay repeated the failure. No timeout relaxation or skip was +made. A current-archive single-case probe and a pinned current-dylib full-source +probe passed; an exact configured rebuild of the original engine test then +passed 36 tests / 207 checks, EOF in 0.7 ms. Source/header/object/executable and +library hashes before/after are retained. Timestamp evidence does not prove a +stale layout or production cause, so the earlier failures remain unresolved +old-executable observations; no speculative EOF patch is claimed. +The invocation journal is `.debug/eof-close-1232026/journal.md`. +A stalled LLDB diagnostic was stopped after inspecting only its task-owned +debugger/test/debugserver tree; exit and preserved receipt are recorded there. + +The final independent command was +`_task123-receipts/client-env/bin/python test/integ/native_websocket_client.py +_task123-build/test/native_websocket_fixture --independent`. +`final-independent-client.log` records actual **websockets 15.0.1**, clean Close, +raw no-peer-response deadline, late/drop ticket, retained handler, local +isolation, handshake/frame ordering, HTTP preservation and backpressure PASS. + +Final runtime, static/Doxygen, native audit and sanitizer outcomes follow below. The failed initial make command is never called a pass. + +## Pre-guard static baseline comparison + +Whole-source complexity and duplication were compared with an exact archive of +base `e1fb7cb4f812e476302bde7d624fc30f8c66ad46`, rather than an older task checkout. +The four inherited complexity functions remain: request dispatch 11, server +listen 11, peer pattern validation 15 and socket accept 11. Server listen's line +number shifts by one because of its standard include. At those checks there was no new offender. +Both trees contain the same two duplication groups: body_reader/response_writer +144 tokens / 43 lines; task.hpp 133 tokens / 26 lines. No new group is added. +Changed-path cpplint, file-size and diff whitespace checks must pass. + +REQ-013 maps to one terminal reason/callback and race tests; REQ-031 to +nonblocking initiation/handler would-deadlock; REQ-032 to fixed deadlines, +sticky tickets and preserved HTTP response; REQ-033 to Close code/reason, +local/global timeout semantics and actual wire/client checks. TASK-128 remains +the later broader parity/interoperability task. + +## Pre-guard segmented gate results + +`final-runtime-check-tests.log`: `make -C _task123-build/test check-TESTS -j1` +passed **218/218**, zero skip/fail/error, after the fresh original EOF rebuild. +`final-check-local.log`: `make -C _task123-build check-local -j1` passed public +and private header boundaries, examples, lint helpers, native platform-only +linkage, README/release/hook documentation, staged install and header hygiene. +Doxygen actually ran and reported zero substantive warnings. + +Fresh ASan/UBSan caught a new progress-test callback fixture error: `observed` +was declared after its callback-owning driver, so teardown wrote to expired +stack storage. `websocket_progress-red.log` retains the stack-use-after-scope +WRITE9 report. The minimal test-only repair moves storage before the driver. +No production change was made. The failed test process and its supervisors +were inspected, stopped and verified gone; report symbolization had stalled. +`inputs-post-testfix.json` verifies the only fingerprint change is that test. +The fresh native archive and five already-passing unchanged consumers are +retained; the affected progress consumer and remaining resume/lifetime/task +consumers are freshly rebuilt. Tests use `symbolize=0` and UBSan +`halt_on_error=1`; preserved logs and source/archive hashes distinguish the RED +from final evidence. This follows the same fixture lifetime ordering enforced +by TASK-122's earlier observer regression; it is not a production lifetime fix. + +`final-asan-post-testfix.log` plus the five unchanged earlier consumer logs +pass all nine selected consumers. The newly rebuilt native fixture passed +`final-asan-client.log`: local timeout isolation, handler-safe drain, +raw clean/late/drop-ticket drain, independent server-initiated Close and +preserved HTTP response tail. Every process exited zero with empty stderr; +UBSan recovery cannot hide diagnostics. Client replay script/source SHA-256 +hashes are in `client-replay-source-hashes.json`. The instrumented native +archive, executable hashes and exact flags are in `inputs.json`, +`inputs-post-testfix.json` and `PASS.json`. + +Supported macOS/arm64 TSan then found a test-framework counter race in the +new drain deadline test. `atos` resolved worker/main writes to the two +concurrent `LT_CHECK` calls (`tsan-drain-red-symbols.log`); littletest's success +counter is non-atomic. Both deadline handlers now publish their receive outcome +in an atomic declared before the owner, and the test thread asserts it after +engine completion. No framework or production patch is made. +`websocket_drain-red.log` retains the failed TSan report. The disturbed ASan +drain consumer was rebuilt and passed 3/29; unchanged archive/consumer reuse is +recorded in `inputs-post-counterfix.json`. TSan uses the same fresh native +archive with newly built current consumers; diagnostic symbolization is disabled +and errors halt execution. Both actual failure observations remain in receipts. + +The actual TSan fixture client exposed a production race after ownership +transfer: `suspension_deadline_locked` still read the HTTP exchange flag while +`exchange::upgrade` cleared it after sink commitment. The frozen base has the +identical exchange header, accessor and store (`timer-race-base-equivalence.json`). +The private watchdog now stops consulting HTTP suspension once phase becomes +pending-101 or WebSocket. Genuine HTTP suspension remains an active candidate; +write-idle, fixed Close and absolute drain timers retain their existing policy. +This is a timer ownership correction at the exercised upgrade/drain seam, +without changing public exchange synchronization or APIs. + +`timer-ownership-red.log` deterministically failed the two transferred-phase +checks (17 tests / 117 checks, 115 success / 2 failure) while preserving the +ordinary-HTTP suspension check. The production repair adds one phase guard +before exchange reads. The final native sanitizer rebuild recompiles only +`connection_engine.cpp`; exact current source/compiler/flag hashes and all 24 +retained object hashes are checked before rearchive. Required consumers and +fixture are relinked against the new current archive. Original failed TSan +fixture evidence is `tsan-client-timer-red.log`. + +`timer-ownership-green-replay.log` passes **17/117**. The first full-suite GREEN +attempt passed the new regression but encountered two unchanged ordinary-HTTP +stop/EOF bounds in quiesce-before-upgrade; refusal itself was observed. That +failure is preserved in `timer-ownership-green.log`, with the exact successful +replay and no timeout relaxation or unrelated production repair. + +The subsequent current TSan upgrade run passed cases 1–15 but caught the +same inherited suspension flag race in the ordinary HTTP refusal path: +`exchange::respond` clears the flag while the watchdog reads it. The phase +guard preserves genuine HTTP timers and cannot cover this HTTP case. +`http1_websocket_upgrade-http-suspension-red.log` and +`tsan-http-suspension-red-symbols.log` preserve the failure; no final race-clean +or completed-task claim is made until this required case is causally resolved. + +## Committed cloud checkpoint: incomplete validation + +This checkpoint preserves the implementation, deterministic timer ownership +regression and minimal private phase guard. **TASK-123 remains In Progress.** +The 218/218 runtime pass, check-local/Doxygen pass and ASan fixture pass above +predate the production phase guard and must not be presented as final-source +validation. The post-guard normal upgrade replay passes 17/117, but current +TSan stops in the HTTP refusal case on the inherited suspension flag race. +The nine-consumer TSan PASS manifest from before the guard is likewise not a +final-source pass; `inputs-final-timerfix.json` and the failed final logs record +the current native archive and preserved 24-object reuse proof. + +At that checkpoint boundary, no broader atomic flag/header repair, further +builds, runtime gates or lint runs were performed. The executor was instructed to commit +this reversible checkpoint for cloud continuation, without merging or marking +the task Complete. Source and generated evidence are retained; no binaries, +keys or capabilities are committed. The caller owns the next repair scope, +final-source checks, validation and any eventual integration into `v3`. + +## Local resume: HTTP suspension and disconnect publication repair + +The user resumed local implementation from checkpoint `b6d5fdef`; cloud startup +was abandoned. The invocation journal is +`.debug/suspension-repair-20261004T031218Z/journal.md`. The earlier failures and +pre-guard passes above remain historical evidence, with their original receipts. + +The initial source matched the checkpoint sanitizer input manifest before an +actual fresh reproduction: `resume-tsan-existing-red.log` reports SIGABRT on +`exchange::respond` writing `suspended_` while the HTTP watchdog reads it. +The engine mutex protects current exchange ownership and deadline anchors, +but handler decisions do not hold it. `resume-decision-red.log` independently +reproduces the flag race through public decisions and concurrent observation. + +Three designs were compared: `atomic_ref` over the existing boolean requires +alignment and access auditing; an engine snapshot requires new notifications +across suspend/decision seams; a private atomic value wrapper centralizes the +existing flag accesses while preserving default public moves. The wrapper is +chosen. Its loads/stores use the default sequentially consistent ordering and +copy the observed value, with independent storage in each moved exchange. +The public move declarations remain defaulted. Genuine move construction, +assignment, moved-from flag values and independent subsequent changes are tested. +This change synchronizes suspension observation without promising general +concurrent exchange decisions. The private protocol-transfer timer guard stays. + +Expanded actual HTTP TSan coverage then found a second inherited defect: +`before-publication-resume-connection_engine.log` aborts in case 14, +`suspension_head_disconnect_cancels`. `resume-engine-red-symbols.log` resolves +the read to `run_handler` in `request_lifecycle.cpp` and the write to the final +cancelled-state assignment in `exchange::disconnect`. The method is byte-identical +to frozen base `e1fb7cb` before repair (`resume-publication-base-equivalence.json`). +Body/writer reason setters only assign values; stop and resume cancellation are +the first wake edges. A posted handler can execute before `request_stop` returns. +The cancelled state was written after those wakes, leaving it unordered against +the resumed handler. The minimal repair publishes state and typed reasons before +fan-out. Terminal response/upgrade states remain intact. A state atomic would +leave the incorrect post-wake observation possible; broader engine deferral adds +unneeded seams. The documented inline executor deterministically exercises both +wake channels: `resume-publication-red.log` is **26 tests / 146 checks, two +cancelled-state failures**; `resume-publication-green.log` is **26/146 PASS**. + +Final fresh ASan/UBSan and supported macOS arm64 TSan each rebuild all **25 native +translation units**, all **13 selected unit consumers** and the actual fixture +in existing owned directories. No old archive/object/binary is accepted after +the final header repair. Builds use one compiler at a time at nice 15; runtimes +run serially at standard priority. Every compile checks at least 2 GiB free disk. +Manual native flags are C++20, pthread, project includes, debug/frame-pointer and +the selected sanitizer; no external backend/include/library flags are present. + +`resume-asan-final-replay.log` and `resume-tsan-final-replay.log` pass all 13 +consumers: exchange decisions **26/146**, routing **15/117**, full original HTTP +engine **36/207**, native server **14/58**, upgrade **17/117**, drain **3/29**, +drain race **3/22**, scope **11/54**, progress **4/43**, session race **9/2068** +(ASan) and **9/2038** (TSan), inherited resume lifetime **1/8**, resume signal +**11/134**, and task race **4/2002**. Across the 154 test cases, ASan executes +5005 checks and TSan 4975; all succeed with zero skipped checks. The actual formerly failing engine +case 14 and genuine HTTP suspension/trickle/header/body timeout cases pass. + +`resume-asan-final-client.log` and `resume-tsan-final-client.log` pass local +timeout isolation with two WebSockets and HTTP, retained handler drain, +raw clean/late/drop-ticket drain and independent server Close. Each fixture +exits zero with empty stderr. `resume-asan-final-independent-client.log` also +passes the full real-wire/backpressure/ordered 64 MiB corpus using actual +**websockets 15.0.1**. UBSan and TSan halt on errors; symbolization is disabled. +`resume-inputs.json` / `resume-PASS.json` in each sanitizer directory and +`resume-final-source-artifact-verification.json` bind exact source, compiler, +flags, archive, executable and client recipe hashes. Earlier manifests/logs +remain under `before-publication-` prefixes rather than being relabeled. + +The executor directly uses `std::condition_variable`; its owning standard +include was missing. Added `` and a first-include standalone +consumer registered in the standard test suite. Both available macOS libc++ +compilers accepted the pre-fix header through transitive includes, so those +probes are **not RED**. The existing Linux tooling container has no C++ compiler; +no exact cloud compiler command was retained and no Linux compiler result is +invented. The final standalone consumer compiles and runs without forced +`-include` or external dependency flags (`resume-final-executor-header*.log`). + +All **26 changed C++ paths** pass current cpplint; file-size and diff whitespace +checks pass. A checkpoint test's misplaced resume-signal include caused eight +lint errors and was moved after standard headers before final sanitizer builds. +Current tools rerun the exact hash-verified frozen base and current source: +the same four complexity offenders and two complete duplication blocks remain, +with no new offender (`resume-final-static-base-comparison.json`). These whole +source gates still return failure for the inherited findings, not a blanket PASS. + +The normal selected suite passed **19/19** before final publication/format edits; +the final normal public-decision regression passes **26/146**. Final full normal +suite, check-local/Doxygen, independent validation and Complete bookkeeping are +the caller's next gates. **TASK-123 remains In Progress.** No historical 218/218 +result is used as final-source acceptance. The repair is ready for review and +independent validation; no merge or push is performed by the implementation agent. diff --git a/specs/architecture/v3/TASK-124-implementation-evidence.md b/specs/architecture/v3/TASK-124-implementation-evidence.md new file mode 100644 index 000000000..885843952 --- /dev/null +++ b/specs/architecture/v3/TASK-124-implementation-evidence.md @@ -0,0 +1,167 @@ +# TASK-124 implementation evidence + +Implementation started from merged `v3` at +`99060cf750acfbfcd3198474edc3fd700915b207`, in the existing registered +`task/TASK-124` worktree.

Before successful listen and after stop, it is inactive: +empty snapshots, no wake/deadline, and `invalid_state` dispatch. Stop unwinds +pending operations and joins workers without further host dispatch. + +The existing poll backend implements the adapter; external mode starts no +internal polling thread. Socket steps, terminal claims, owner enqueue, and +ordered timer sweeps are shared with managed mode. Adapter code lives in +`io_external_adapter.cpp`; wake-source implementation lives in +`io_wake_source.cpp` to keep the platform header within its size ceiling. + +Each socket lifetime has an identity independent of its descriptor. Snapshot +omission revokes the published generation; republishing cannot authorize an +old callback. Release/re-adopt uses a different lifetime, including actual +POSIX descriptor reuse. Identity/generation exhaustion fails without wrapping. +Dispatch validates identity and acquires a shared socket lifetime under the +registry mutex. That lifetime survives detached batches and defers physical +close until dispatch relinquishes it. Rearm checks the operation's original +lifetime against the current registration; a matching private connection ID +alone cannot revive old work. Accepted sockets are rejected/closed if listener +retirement or shutdown wins registration. Owner enqueue happens outside the +registry lock, including immediate rejection after close. + +Snapshots prune retired registry records and own complete socket/wake/deadline +values, so repeated external connections do not accumulate tombstones. Timer deadlines are +actual pending deadlines, and expiry retains `(deadline, sequence)` ordering. +An RAII dispatch guard rejects overlap and recursion before consumption, and +host time must be nondecreasing. Dispatch processes readable data before close +or error teardown where socket results permit it. + +Notification is separate from private wake-operation completion. Publishers +coalesce one token under the registry mutex; acknowledgement takes the same +mutex and performs one bounded read before processing events. A concurrent +mutation either precedes that acknowledgement or leaves a readable token +behind it. Dispatch has no trailing drain. Interrupted writes retry; only +actual would-block buffer fullness counts as an existing notification, and +hard signal/acknowledgement failures terminate work. Construction/nonblocking +setup failure leaves an invalid source for the typed pre-bind listen gate. +There is no external-mode idle polling fallback. + +The public-header-only native example and its POSIX poll/Windows WSAPoll helper +retain pairs alongside native registrations and rebuild a complete set after +successful dispatch.

They cover +pending-until-dispatch behavior; read/write/accept completion; masks, owned +snapshots, and usable wake handles; spurious/duplicate/all-false callbacks; +unknown keys, wrong generations, and omitted/republished registrations; all +16 old-event flag combinations after same-ID and actual descriptor reuse; +detached read and accept release/reopen before rearm; timer deadline boundaries, +ordering, cancellation races, and decreasing-time rejection before socket I/O; +work after snapshot and during mutex-controlled acknowledgement; publication +during a barrier-controlled in-flight dispatch; recursive and concurrent +dispatch rejection; physical close deferral during completion; shutdown and +hard wake failure; identity exhaustion; buffered read with combined close/error; +descriptor zero as a valid carrier; and bounded retired-registry cleanup. Private member-pointer access controls +otherwise unreachable scheduling boundaries without production test hooks. + +Native-server tests also force wake construction failure in an isolated POSIX +child with a zero descriptor soft limit and verify typed failure before bind. +The child has a bounded wait and restores no shared process limits. + +Public-API HTTP/1 integration covers GET, bounded POST, keep-alive/pipelining +with ordered response bodies, a deliberately gated worker response with +observed wake dispatch, header deadline expiry through empty dispatch, close +and reconnect with retained stale callbacks, and host-driven drain/stop with +registration removal. + +## Local verification + +Local platform: Darwin arm64, Apple Clang 21.0.0 +(`arm64-apple-darwin25.3.0`).

The complete local gate also includes source/installed public +header consumers, the native dependency audit, staged install layout/hygiene, +and zero-warning Doxygen generation. + +After the registry-cleanup repair, `final-build.log` records a successful +serial examples-enabled build and `final-full-check.log` records the complete +`make -C _build/task-125 -j1 check`: 223/223 executables passed, with zero +failures, skips, or errors (exit 0). This final full run includes every focused +target against the final library and test source. The adapter suite passes +19 tests / 406 checks; public HTTP/1 integration passes 4 / 52; native server +lifecycle passes 17 / 76. Source/installed consumer checks, native dependency +auditing, staged installation/hygiene, and Doxygen checks pass in that same run. + +The actual example was run against the final native core as: + +```sh +_build/task-125/examples/v3_external_event_loop 3 +curl --silent --show-error --fail --max-time 2 --header 'Connection: close' --write-out '\nSTATUS=%{http_code}\n' http://127.0.0.1:49179/hello +``` + +`example-smoke.log` records the example's printed port 49179, HTTP status 200, +exact body `hello from an external loop` followed by newline, curl exit 0, and +example exit 0 within its three-second invocation budget. A bounded subprocess +probe asserts those bytes/status/exit codes and terminates any failed child; +no example server remains running. The smoke runs the actual example binary, +not the integration fixture. + +## Static checks and inherited debt + +Changed-file `python3 -m cpplint --extensions=cpp,hpp --headers=hpp` passes. +`scripts/check-file-size.sh` passes without new exemptions; extraction of the +wake implementation repaired the temporary 505-SLOC platform header. +`git diff --check` passes. + +The full complexity command still exits 1 for three unchanged baseline +functions: `dispatch_request` (CCN 11), `valid_peer_pattern` (CCN 15), and +`accept_one` (CCN 11). A `git archive HEAD src` baseline, measured with the same +Lizard tool, records those same offenders plus the old `impl::listen` (CCN 11). +This change reduces listen below the threshold and adds no offending function. +See `baseline-complexity.log` and `complexity.log`; the full complexity gate is +not claimed passed. + +The full duplication command still exits 1 for the identical two baseline +clusters in `body_reader.hpp`/`response_writer.hpp` and the two task specializations +in `concurrency/task.hpp`. No changed/new code appears in the reported clusters. +Same-tool baseline/current receipts are `baseline-duplication.log` and +`duplication.log`. The full duplication gate is not claimed passed; inherited +cleanup remains a repository-owner concern outside TASK-125. + +## Platform and workflow limits + +Only the local macOS build/runtime/package checks were executed.

Per the +user's AGENTS policy, those checks belong to CI and the v3 PR and do not block +local completion. POSIX dup2, descriptor-zero, and descriptor-exhaustion probes +are explicitly POSIX coverage. Groundwork validation, runner-owned commit, +merge into v3, and worktree cleanup remain the caller's next phases. + + +## Validation repair iteration 1 + +The executor receipts above describe the original implementation. The current +repair adds transactional socket-direction and shared due-timer collection: +all potentially throwing vector growth finishes before registry erasure. Both +readable and writable collections finish before either is detached in an +external event. Managed dispatch uses the same collection helper, and timer +expiry preserves `(deadline, sequence)` ordering and owner enqueue outside the +registry mutex. + +Eight bounded regressions now cover allocation failure in read/write/accept +collection, failure while collecting the second direction, due-timer allocation +failure, generation exhaustion after maximum-generation snapshot omission, +and real successful native accept followed by listener retirement or backend +close before registration. The accepted-socket cases split the existing native +accept/registration boundary using private member access, retain the listener +lease, and exercise actual teardown and production registration/completion +helpers; they add no scheduling hooks. + +Iteration receipts are in the runner-owned validation findings directory under +`repair-iter1-*` names. `socket-probe-red.log` and `timer-probe-red.log` reproduce +the original one-of-two operation loss. `suite-red-authorized.log` records the +five allocation regressions failing before repair. `guards-mutation-red.log` +records new exhaustion and both accepted-socket tests failing when the existing +guards are temporarily removed; the original guards were restored exactly. +`socket-probe-green.log` and `timer-probe-green.log` both report two pending +operations before close, two completions by close, and both states terminal. + +Focused final receipts, all with zero failures/skips: + +- `suite-green.log`: external adapter, 27 tests / 491 checks. +- `managed-contract-green.log`: shared managed I/O contract, 41 / 734. +- `fake-timer-green.log`: fake backend/timer coverage, 14 / 2523. +- `native-server-green.log`: native server lifecycle, 17 / 76. + +The focused runtimes used authorized local loopback access. An initial restricted +sandbox adapter run failed listener creation and is not passing verification. +Changed-file cpplint, `git diff --check`, and source file-size checks pass; +existing macOS linker warnings remain. The repair performed no staging, +commit, merge, or finalization. Final broad gates and acceptance remain +coordinator-owned; nonlocal platform checks remain assigned to CI and the v3 PR. + +## Validation repair iteration 2 + +The first repair's two detachment loops raised `dispatch_event` to CCN 11. +A shared private `detach_batch_locked` now performs registry erasure for both +external dispatch and managed direction dispatch. Both external direction +collections still finish before either detachment call, and detachment remains +under the registry mutex. Dispatch, completion, and timer behavior are unchanged. + +The unchanged complexity threshold now measures `dispatch_event` at CCN 9, +`detach_batch_locked` at CCN 2, `take_direction_locked` at CCN 1, and +`collect_direction_locked` at CCN 7. The full complexity command still exits 1 +only for the three inherited offenders named above; it is not claimed passed. +Changed-file cpplint, source file-size, and `git diff --check` pass. + +Focused regressions pass with zero failures/skips: external adapter 27 tests / +491 checks, managed I/O contract 41 / 734, and fake backend/timer 14 / 2523. +The native core and these three test executables were rebuilt before running. +Receipts are in the runner-owned validation findings directory under +`repair-iter2-*` names. This is a private refactor verified by the existing +allocation-failure and I/O regression coverage; no new tests or public contracts +were added.

Tokens cannot wrap; closing/releasing invalidates an incarnation before fd reuse. `close()` joins the driver before owner/executor teardown, with driver-local shutdown handling retained. Independent poll remains the shared oracle.

These contain 245 littletest cases; the linkage smoke target has its own exit-code oracle. The kqueue suite executes 48 cases, including all applicable shared scenarios, queued/new reads after buffered EOF, independent read/write progress and cancellation, latent accepts/reads, backpressure, stale tokens/fds/filters, gated in-flight buffer/socket leases, concurrent close, fatal/mixed/error receipts, control/wait EINTR, wakes, timers, and disabled EOF iteration bounds. + +Real receipt observations from the normal kqueue log: buffered EOF with pending bytes occurred 6 times across 7 socket events, with 8 successful controls; invalid registration produced one nonzero EV_ERROR receipt. A public native-server HTTP request completed byte-exactly and generated 18 kqueue waits and 3 socket events. Fresh poll/kqueue fixtures produced identical 17-entry normalized semantic traces and identical 262144-byte backpressure streams, including actual initial partial writes.

TSan reported no races. + +Changed-file cpplint, file-size, public-header gates, warning-suppression, assertion, fence checks, and native source/binary linkage audit passed.

The reader now stops at staging/tail bounds, + replays retained bytes before further reads, and resumes on released room. + A second failing resume probe exposed notify-before-park: room callbacks + now acquire the engine registration mutex after releasing the body mutex, + and the locked reader posture retries any eligible tail. +- ASan caught `stack-use-after-scope` in the existing outbox corpus's + coroutine helper: a temporary string was passed by reference across + suspension. The helper now owns its payload by value. +- Fixture corrections are recorded separately from library repairs: the + input plateau fixture drains the 101 response so its tiny socket buffer + can admit the later Close reply, and retains the session through its Close + callback.

Producers reuse fixed buffers. Full staging, kernel `would_block`, +and stable output admission (20 ms with deadline-bounded probes) establish +backpressure before sampling. Attempt windows are 1 MiB then 8 MiB. + +- HTTP body and outbox budgets: 1,024 bytes each; outbox measurement permits + fixed serialized-head overhead up to another 1,024 bytes. +- WebSocket receive budget: 512 bytes / eight 64-byte messages; send budget: + 522 bytes, with seven 66-byte frames reaching backpressure. +- Pending input tail: staging cap plus at most one 16,384-byte read buffer; + the writer's scratch buffer is a fixed 4,096 bytes. +- Actual retained process RSS is sampled with macOS `task_info` or Linux + `/proc/self/statm`.

No allocation + operators are overridden; sanitizer ownership is preserved.

Its historical artifacts and acceptance status were preserved. + +1. **Verified consumer closure lifetime error.** The immediately invoked captured coroutine lambda dies at the creation statement; its lazy body dereferences the expired closure during executor draining. The original ASan baseline reproduced `stack-use-after-scope`, exit 1. The stronger regression still using that closure also reproduced the fault, exit 1. Replacing only the temporary closure with a named coroutine taking `resume_signal` by value eliminated it. The signal lives in its coroutine frame. The regression checks lazy start, both suspended signal/cancel winners, an already-fired signal, shared copies, losing/repeated triggers, one completion and a drained queue. Every completion requires a value; `main()` returns the real check status. A temporary copy deliberately expecting `value_seen == -1` exits 1, proving failed checks reach the process result. +2. **Verified allocator ownership conflict.** The actual Clang18 TSan lifetime target fails to link because its global `operator new/delete` conflict with `libclang_rt.tsan_cxx`. The direct source link exits 1 and the configured make target exits 2 with those exact duplicate definitions. The ownership guard follows `websocket_drain_race_test.cpp`: explicit `LHS_SANITIZER_OWNS_OPERATOR_NEW`, GCC TSan, and Clang thread/memory/leak feature detection. Global overrides and all hook-only state are guarded together. The actual configured target and an automatic Clang TSan detection build without the explicit ownership define both link and execute successfully. + +The original forced timeout-registration reclaim case remains active under normal and ASan/UBSan. Both signal and cancel winners assert the hook fired, one delivery, the correct result, waiter destruction and list removal (12 checks total). Timer initialization stays outside the injection window. This target contains no explicit allocation-failure test; its allocator throws only when real `malloc` fails. No unrelated `bad_alloc` acceptance was added, and other owner suites were not changed. + +Only `published_waiter_can_die_during_timeout_registration` skips in sanitizer-owned lanes, with this reason: `sanitizer owns operator new; timer-allocation reclaim hook runs in normal and ASan/UBSan lanes`. The suite keeps two allocator-independent race cases active: 100 competing signal/cancel iterations and 200 suspended-frame retirement iterations covering both winners and both already-queued wakes and racing publication. Start gates use atomics, observations follow joins, and the retirement case proves no resumed body, retired witness, released node and empty waiter/queue state. There are no added sleeps or sanitizer suppressions. + +## Executed commands + +All commands ran from this worktree, using Ubuntu Clang **18.1.3**, C++20 and the retained optimization/debug/instrumentation flags.

TASK-185 and its frozen artifacts were only read. + +## Verified causes and repairs + +1. **Response fixture ownership.** `fake::byte_span("kept")` implicitly creates a temporary string. The counter-only keeper did not own its bytes. Fresh baseline ASan reproduced the retained `borrowed_destruction_releases_keeper_once` stack-use-after-scope. Strengthening the case with exact byte/length assertions reproduced it again before repair. The local `leased_payload` now owns both the immutable string and release counter, and the span and lease refer to that same owner. No production response API, body sink or borrowed-data copying changed. +2. **Multipart lazy-reference ownership.** Public `read_multipart(exchange&, const multipart_limits&, part_sink&)` previously saved the limits reference across initial suspension. The original temporary call in `read_disconnect_aborts_once` reproduced the retained stack-use-after-scope. New call-time mutation coverage failed six assertions, and an ordinary named helper returning an unstarted task with temporary custom limits independently reproduced ASan failure. A synchronous public wrapper now copies the four scalar budgets into a private by-value coroutine frame at invocation. Admission and decoding remain lazy. Exchange and part sink stay explicitly borrowed through task completion/destruction. + +The public multipart signature and exported symbol are preserved, including the exact installed function-pointer assertion. The wrapper avoids a public by-value signature/symbol change; copying only inside the old lazy body was rejected because it would still dereference expired limits. The journal compares both interfaces on depth, locality and seam placement and records the adversarial doubts. Temporary-helper ASan, lvalue mutation, cancellation and staged symbol/type checks clear those doubts. Git revert provides rollback; no irreversible external state changed. + +The registered route closure in `make_multipart_route` persists in the registry through the existing route tests. Its helper borrows that live closure's limits/handler. The original and helper-temporary multipart failures reproduce through the direct public read boundary without any coroutine lambda, separating the reference cause from closure ownership. Added helper functions returning tasks are ordinary functions; no temporary captured coroutine lambda was introduced. + +## Regression behavior + +- Borrowed response tests cover delayed executor start after dropping the application owner, replay through a definition copy, parked partial writes under a four-byte queue bound, explicit cancellation and disconnect. They require a value result, exact bytes/counts, one completion, no later output after terminal handling, and one keeper release only after the final legitimate definition disappears. Existing file/pipe transfers and concurrent replay tests remain active. +- Multipart tests keep the original temporary syntax, exercise temporary custom limits after the helper returns, mutate lvalue limits before starting, and assert individual names/part bytes (`a=1`, `file=payload`), completed counts and no abort for completed parts. Parked disconnect/cancel cases require typed value completion, one delivery, one begun-part abort, zero completed parts and no response output, including repeated terminal notifications. Existing malformed/budget/file/decoder/corpus checks remain active. +- The new registered/distributed `consumer_v3_multipart_runtime` uses installed public headers only. It feeds a bounded body through the public body-source seam and real multipart decoder; both lvalue mutation and temporary-helper scenarios check one completion, exact field name/value and one successful part with zero aborts. The existing vocabulary consumer remains link-free and now asserts the exact unchanged read signature. +- Migration documentation states call-time limits ownership and that a response lease must own the actual borrowed storage. + +## RED evidence and counts + +All ASan runs use leak and stack checking; no lifetime suppression was added. + +| Receipt | Result | +| --- | --- | +| Fresh original two-target baseline | scoped make exit 2, 0/2 passes; each direct target exit 1 with its retained ASan stack-use-after-scope | +| Strengthened response regression | exit 1, ASan abort at case 8 | +| Strengthened multipart regression | six failing checks in lvalue-snapshot case 9, followed by ASan abort in temporary-helper case 10; exit 1 | +| Staged installed lvalue snapshot consumer before fix | compile/link exit 0, runtime exit 1 | +| Separate staged temporary-only consumer before fix | compile/link exit 0, runtime exit 1 with ASan stack-use-after-scope | +| Corrected response/multipart targets | 30 cases / 304 checks and 14 cases / 178 checks, respectively; all six final lanes exit 0, zero failures/skips in these targets | + +ASan aborts do not print final harness totals; partial RED totals are not claimed. `red-response_sources_test.cpp`, `red-forms_multipart_route_test.cpp`, `red-*.log`, and `red-results.json` preserve the source state and receipts.

No failing required affected check is being deferred or replaced. + +## Tracking, checks and reusable notes + +All four TASK-187 implementation action items are checked. Card/index remain In Progress pending caller-owned Groundwork validation/finalization. `cpplint` passes all six changed C++ files, `git diff --check` passes, and `make -C build/task187-implementation/normal-off lint-littletest-skip-exit-code` passes. The new runtime consumer is registered in `check_PROGRAMS` with `SOURCES` for distribution and public-library linkage. + +No configured task-executor memory store exists. Reusable notes: setup is `./bootstrap`, fresh out-of-tree configure, `make -C /src` before scoped test make. Set `TESTS`, `check_PROGRAMS` and `noinst_PROGRAMS=` together. Regenerate Automake/config.status after adding target rules to configured lanes. Unit tests use `test/littletest.hpp` in `test/unit`; consumer checks live in `test/headers`. Avoid temporary captured coroutine closures; a synchronous function can snapshot values into a private by-value coroutine without altering public ABI. A response lease must pin the exact span storage. Run ASan/TSan outside ptrace without disabling diagnostics. + +Requirement traceability: PRD-V3N-REQ-021/024/025 and DR-V3-003/006 map to bounded multipart reads, delayed start, typed cancellation and begun-part cleanup. PRD-V3N-REQ-026/028/029 and DR-V3-005 map to explicit leased storage, one completion, immutable replay and bounded partial sends. PRD-V3N-REQ-038 maps to the retained multipart decoder/route/files/corpus behavior and migration ownership notes. + +BSD/macOS/Windows and other nonlocal checks were not executed; they remain CI/v3-PR owned under AGENTS.md. The unresolved extra intermittent race remains caller-owned before TASK-185's final gate.

Their source receipt identifies the unchanged peer-policy implementation as `ec279b7f87468f5efe7f47b31f6fc0931254475911629e1aee1108f4ad558236`. These receipts were read without modification. Their timeout alone did not prove the cause. + +The invocation journal is `/home/etr/progs/libhttpserver/.worktrees/TASK-188/.debug/peer-policy-mutation-starvation-mpOFOu/journal.md`. A direct unchanged original test baseline happened to pass: 9 cases / 64 checks, 69.9 ms. The stall is schedule-dependent. The bounded discriminator retains the original two writers, 200 mutations each, and six continuously running readers, establishes reader pressure with a start gate and 600 completed iterations, and adds 1024 disjoint unmatched deny patterns to extend overlapping scans. Its independent `steady_clock` bound is 15000 ms; no sleeps, reader/mutation reductions or release deadline extensions were introduced. + +Verified RED against the actual base source (and separately its original shared library) showed 0/400 completed mutations while 6,969,291 and 9,061,804 reader iterations completed. After the test first records failure, reader-pressure cleanup releases the pending writer acquisitions; both return immediately (2 completed mutations before their safe stop boundaries), all workers join, and littletest reports two assertion failures with exit 2. This disproves a lock cycle and supports reader-preferred shared-mutex starvation across scans/getters. The final stop-token-aware regression was also compiled against the copied base source and failed with 0/400 mutations, 3,778,384 reader iterations, and 2 cleanup completions. Its steady-clock observation was 15008 ms including joins. External timeout 50s is only containment; it did not produce the failure. + +Direct RED/GREEN commands use `/usr/bin/clang++-18 -std=c++20 -pthread -O1 -g -Isrc -Itest test/unit/peer_policy_test.cpp src/detail/net_address.cpp -o `. Base source is copied by `git show v3:src/detail/peer_policy.cpp`; no production worktree revert was needed. The complete unchanged original test source is preserved as `.debug/peer-policy-mutation-starvation-mpOFOu/original-peer-test.cpp` (SHA256 `d249c153f8d51967c22d11251c57a431b1e930584064e19adf2b8326f867e84b`). Initial GREEN executes 11 cases / 2699 checks without failures; 400/400 mutations complete in 13 ms including joins. A focused direct TSan probe completes 400/400 in 160 ms without diagnostics. Final six-lane results below supersede those exploratory timings. + +## Publication repair and cleared doubts + +One immutable generation owns deny/allow vectors, mode, enabled and derived armed state. A writer mutex serializes copying the latest generation and publishing the candidate, preventing completed additions/removals or stance updates from being overwritten by independent writers. Parsing remains before writer serialization. C++20 atomic shared-pointer release publication and acquire loads retain vector lifetime through both scans. Atomic shared-pointer operations are not claimed to be lock-free. A plain exclusive mutex was rejected because it retains global scan contention and does not implement architecture §3's publication responsibility. + +The scalar `armed()` fast path remains one acquire load. Writers publish the generation before release-storing its derived gate. After passing that gate, classification checks the retained generation's own armed state (including enabled). This closes the old gate/disabled-state mixing opportunity. Calls overlapping publication may use an older complete generation; subsequently synchronized operations observe the completed mutation. No cross-call armed/enabled or mode/classify equality is asserted while mutations run. + +Concurrency doubts are covered by the bounded reader-pressure regression; two independent 200-operation add/remove writers overlapping a third 400-iteration mode/enabled writer, with all settled deny/allow entries checked; six-reader legal-generation classification during 400 disable/mode/re-enable cycles; synchronized disabled/re-enabled checks; and full sanitizer transport/lifecycle coverage. Candidate allocation fails before publication, leaving the previous generation intact. Add/remove retain throwing allocation behavior and typed invalid-pattern outcomes. Existing `noexcept` setters now allocate to copy a generation: allocation failure terminates, with no silent update dropping or public declaration changes. This tradeoff is explicitly recorded in architecture §3. No custom reclamation queue or additional production dependency is introduced. + +Unit workers use stop-token-aware C++20 jthreads, including exception cleanup of partially constructed groups. Successful-path readers stop only after writer completion; failure is recorded before pressure is released. Parser identities, overlap/no-op behavior, both truth tables and reasons, family/unspec rules and public header types retain their existing tests. Listener/request lifecycle code needed no production changes. + +## Local lane configuration + +All six fresh lanes use Ubuntu Clang 18.1.3 (`/usr/bin/clang-18`, `/usr/bin/clang++-18`), C++20, `--disable-examples`, and common flags `-std=c++20 -pthread -O1 -g -fno-omit-frame-pointer`. TLS-off uses `--disable-v3-tls`; TLS-on uses `--enable-v3-tls`, `V3_TLS_CFLAGS=-I/home/etr/progs/libhttpserver/build/tooling/provider/include`, `V3_TLS_LIBS='-L/home/etr/progs/libhttpserver/build/tooling/provider/lib -lssl -lcrypto'`. The existing provider is reused, not rebuilt. + +ASan/UBSan adds `-fsanitize=address,undefined -fno-sanitize-recover=undefined -fsanitize-address-use-after-scope`; TSan adds `-fsanitize=thread` and the established `-DLHS_SANITIZER_OWNS_OPERATOR_NEW` allocator-ownership define.

The public readiness example helper is copied alongside it. `installed-compile.log`, `installed-ldd.log` and `installed-run.log` identify the exact compile, selected library and traffic. Each receipt hashes staged include/library and executable identities. TLS refers to library configuration; these listeners deliberately use plaintext HTTP/1. + +Each loop mode uses one ephemeral loopback server throughout the live updates. Independent OS socket clients verify HTTP 200 / body `policy-ok`, handler-driven deny, disable/re-enable, remove, reject-all, allow and accept-all changes, restoration without restart, deny-over-allow under reject-all and allow-over-deny under accept-all. A separate 127.0.0.2 administrative client remains allowed while 127.0.0.1 is refused. A response following the completed mutation synchronizes every subsequent probe. Already accepted keep-alive revalidation and new-connection refusals both observe zero application bytes. Each scenario observes 7 accepted and 5 refused accept hooks plus typed `peer_refused` request completion for the already accepted connection. Both managed and externally driven public readiness modes pass; success/failure cleanup closes clients, initiates stop, wakes/joins the external host and stops the server while handlers/counters remain alive. + +The first exploratory consumer smoke exposed a fixture error: temporary owning hook handles immediately deregistered the observations. Retaining both handles through stop fixed the fixture; all transport assertions already passed. This was not a listener fault and required no hook/publication refactor. + +## Final gate results + +All six final lane receipts pass. Each builds the library, executes all 15 affected programs, runs the complete strengthened peer_policy binary under the unchanged 180-second containment, installs the package, and compiles/runs the standalone public consumer in both loop modes. All final commands exit 0; no sanitizer diagnostic appears in affected test, direct peer or installed consumer logs. + +| Lane | Programs passing | Harness cases / checks / skips | Writer completions | Steady-clock mutation bound observation | Installed loops | +|---|---:|---|---|---|---| +| normal-off | 15 | 179 / 4099 / 0 | 400/400 | 17 ms / 15000 ms | managed + external pass | +| normal-on | 15 | 179 / 4099 / 0 | 400/400 | 10 ms / 15000 ms | managed + external pass | +| asan-off | 15 | 179 / 4099 / 0 | 400/400 | 60 ms / 15000 ms | managed + external pass | +| asan-on | 15 | 179 / 4099 / 0 | 400/400 | 63 ms / 15000 ms | managed + external pass | +| tsan-off | 15 | 179 / 4097 / 1 | 400/400 | 215 ms / 15000 ms | managed + external pass | +| tsan-on | 15 | 179 / 4097 / 1 | 400/400 | 210 ms / 15000 ms | managed + external pass | + +Every peer_policy execution runs all 11 cases / 2699 checks / 0 skips.

Each private and installed runtime invocation reports, for each loop mode, 7 accepted hooks, 5 refused hooks and 1 typed peer_refused completion. Accepted HTTP status and body are asserted on every accepted request; refusals assert zero application bytes. Installed ldd outputs select each lane's own prefix/lib/libhttpserver.so.3. + +Both normal lanes additionally run the complete original unchanged 9-case / 64-check peer_policy source against the staged installed shared library under timeout 180s: exit 0, no failures/skips. Original concurrent-case times are 3.167 ms (off) and 1.105 ms (on); exact process wall times and command identities are in receipts. These retain the original two-writer, 200-mutations-each and six-reader workload. + +A demonstrated fixture blocker required an explicitly authorized scope addition. Both initial TSan request_lifecycle links failed because the fixture's unconditional global new/delete override conflicts with TSan-owned definitions. Frozen initial-allocator-link-failure-focused-check.log and initial-allocator-link-failure-receipt.json preserve this RED in each TSan lane. The existing repository sanitizer-ownership guard pattern now avoids that override only when the sanitizer owns the allocator. In zero_hook_commit_allocates_nothing, both functional commit-call assertions still run; only its two allocation-count assertions skip explicitly. Thus TSan request_lifecycle executes 31 cases / 171 checks / 1 skip, while normal/ASan retain all 31 cases / 173 checks / 0 skips. Normal TLS-off/on were rechecked after this final fixture edit; lifecycle-final-recheck.log and receipt entries prove that behavior. No production lifecycle/timer repair, new suppression or diagnostic disabling was introduced. + +cpplint passes all five changed C++ files. The littletest skip/result contract passes (77 for all-skip, 0 for mixed success+skip, failure count for fail+skip). git diff --check passes. The new consumer source is registered in Automake check_PROGRAMS/SOURCES and its reused public host helper is already distributed by examples/Makefile.am.

The normal/off/on and ASan/off raw failures occur inside the sequential handshake-split loop; ASan/on's recorded failure occurs during refusal probes. Independent websockets 15.0.1 completes echo/text/binary/ping/close and then times out opening `/flood`. The raw request contains valid CRLF, nonce and version headers. + +Fresh task-local baseline reproduces the split-loop EOF. A bounded copied client prints exact request/101 bytes, split numbers and monotonic connect events; temporary engine instrumentation prints admission free space, effective limits and finalization IDs. It is removed after collecting the discriminator. Successful sessions restore the entire budget; this is not an accumulated leak. The failing overlap is explicit in `probe-instrumented.log`: upgrade 25 sees output capacity 4194304, reserves 4194048, and the next upgrade 26 sees only 256 free bytes before FINALIZE 25. It refuses `WebSocket queue storage exhausted`; the ordinary refusal cannot allocate its response either. No readiness or handshake writer repair is indicated. + +The fresh `/flood` discriminator shows effective message limit 1039030 and logical output 1039040 despite the fixture requesting a 1048576-byte message and 1048586-byte output queue. Existing production accounting reserves four times logical output plus fixed queue/control storage against the fixture's default total 4194304-byte server output budget. The first MiB send is permanently `rejected` with `limit_exceeded`, not backpressured. The fixture treated rejection as retryable and repeatedly awaited an already-ready `writable()`, occupying route workers before 101 could flush. A copied diagnostic fixture which terminates on rejection immediately emits the complete 101 and the rejection reason. Original pinned independent failure and discriminator logs remain separate. + +The caller explicitly amended the saved plan: correctly provision the fixture's total server storage for the original declared workload; retain every route message/queue limit, client predicate, frame count and deadline. This is authorized fixture configuration correction, not a production limit increase. Four live sessions cover the three-session isolation case and one retiring predecessor. Each input reservation is `5 * 1048576 + 16384 + 4096 + 256`. Each output reservation is `4 * 1048586 + 4096 + (8192 + 256) * 4`, with 256 bytes per handshake and 4096 bytes for ordinary HTTP response storage. Total input/output/message budgets are exactly **21054464 / 16934048 / 4194304 bytes**. Logical incoming/outgoing message counts remain one, input/message size remains one MiB and output remains one MiB plus ten frame-header bytes. Two workers and all timeout settings remain unchanged. The public low-budget negative probe still observes production admission refusal. + +`src/detail/connection_engine.cpp`, `connection_engine_websocket.cpp` and the complete original client are byte-identical to the base; `.debug/.../unchanged-identities.json` records their hashes. No production code, ownership interface, dependency or default budget changes. Architecture updates are therefore unnecessary. + +## RED/GREEN and fixture lifetime repair + +The added public regression initially uses the unchanged retry loop and server storage. Both `red-rejected.log` and `red-flood.log` fail at the existing five-second socket handshake bound, exit 1; external timeout 25s is containment, not the assertion. The diagnostic copy independently establishes the exact typed rejection. The repair handles `rejected` as terminal, reports its reason and fails unexpected flood rejection instead of retrying writable. `/reject-send` intentionally sends one byte over the unchanged message limit and asserts rejection, complete valid 101 and clean Close. + +A separate new Close-while-writable-stalled regression first fails `unexpected EOF` inside a pinned data frame (`supplement-regression.log`). The fixture returned on closed writable, destroying its owning session before the partially written frame and peer Close reply could drain. The minimal repair waits on its existing close notification gate on closed send/writable paths, as its receive path already does. `close-green.log` passes complete-frame and Close assertions. Production session/driver state is unchanged. A per-session notification witness catches duplicate callbacks; final fixture exit requires every accepted session to have exactly one callback after stop. Host readiness threads join before server destruction, while callbacks, route state and the server remain alive. + +The supplemental public client validates the complete 101 status, Upgrade/Connection/Accept fields and absent Content-Length, Transfer-Encoding and extension headers before reading any data; the raw codec retains coalesced suffix bytes. It validates all 64 ordered one-MiB frames, observes an outstanding writable with reads paused, injects Ping and verifies Pong within three complete data frames after reads resume. Close under backpressure preserves complete pinned frames; rejection stays typed; fragmented text with interleaved Ping/Pong, exact/excess input size, parked receive cancellation, low-budget admission refusal and handler-safe request_stop are exercised. The unchanged raw client separately retains all 153 handshake boundaries, three coalesced messages, malformed handshakes, HTTP header timer removal, application return/throw, two-session isolation, writable cancellation and completed/expired/dropped drain tickets. The unchanged pinned independent flow remains a separate gate. + +## Build and verification configuration + +Fresh task-local normal and ASan/nonrecovering UBSan lanes, TLS-off/on, use `/usr/bin/clang-18`, `/usr/bin/clang++-18`, `-std=c++20 -pthread -O1 -g -fno-omit-frame-pointer`, and `--disable-examples`.

Initial sandbox configure probes hit LeakSanitizer's ptrace restriction; their `initial-ptrace-config.log` remains preserved. Required sanitizer checks run outside ptrace with all checks enabled.

They contain five route-effect failures plus the aggregate 47!=52 assertion: six checks, one oracle cause. The fresh unchanged task-local baseline exactly reproduces those six checks (`baseline-red.log`, four tests, 944 checks, zero skips). Bootstrap/configure/library/baseline command logs are retained. + +PRD-V3N-REQ-023 makes decisions possible at complete request headers; it does not require a lazy handler to execute before the parser's next frame. REQ-025 requires cancellation. Architecture §§3.3–3.4, DR-V3-001/003/006, `docs/task-140-http2-evidence.md` and `docs/task-142-http2-evidence.md` retain connection-owned HPACK/flow control and serialized, executor-affine guarded route resumes. The existing `http2_reset/peer_reset_invalidates_queued_and_parked_handlers_and_returns_reservations` explicitly requires zero calls if reset precedes executor start and one call if it already started. + +`http2_request_state.hpp::admit` posts the route task. `reset/discard` disconnects it; subsequent owner reaping invalidates its queued frame witness. The original five `feed` entries parse both their valid opening and later error before running any pending handler, then incorrectly expect route 1. Running stale work or invoking handlers inline would violate the documented lifecycle. No production defect is demonstrated. + +The minimal repair gives those same five entries the explicit `dispatch` stage. Executor turns occur only at completed protocol frames. The opening handler records its actual head and suspends on an application signal, leaving the request active until its later stream error cancels it. Output retirement remains deferred until the transcript is parsed. Every original route payload, RFC verdict and wire file is unchanged; the corpus still contains exactly 52 entries. Unknown stage values now fail explicitly. + +A completed response is a distinct state: `prepare_response` marks the send side ended at the semantic response, and the next owner reap removes an END_STREAM request even before output retirement. The initial dispatch-only probe documents that `closed-data` and `half-closed-head` then correctly produce connection STREAM_CLOSED (`schedule-green-initial.log`). The final dispatch stage suspends those handlers rather than pretending a completed stream is still half-closed. Separate completed-response regressions retain and verify that connection verdict for both inputs across every fragmentation split. No wire-error oracle is weakened or made nondeterministic. + +## Causal RED and discriminating GREEN + +Before correcting the harness/metadata, new paired regressions passed all eight deferred controls but failed all eight started controls at `route effects`, yielding 14 failures together with the six original checks (`schedule-red.log`). This is the expected missing executor boundary, not a timeout or build error. Final GREEN logs retain the source identity and exact protocol observations. + +A bounded task-local discriminator also compiles a copy of the final harness +with only dispatch-stage executor turns removed. It reintroduces all five +original route failures and all eight started-control failures, plus the two +aggregate completion-count failures (exit 15). `discriminators/receipt.json` +records the exact compile command and source SHA256 +`9875ffd708a273c06f97c7de401e3b1553e594979aecdcf4ce18fd966a58e2fc`; +`discriminators/red.log` retains the assertions. The real harness and production +tree are untouched by this probe. Exact baseline source/metadata copies are +retained alongside it. This independently confirms the causal scheduling seam +after adding final diagnostic/count assertions. + +For each named later error, paired schedules append an independently authored dynamic-table insertion on reset stream 1, then a sibling on stream 3 references index 62. They require its actual `x-route: after` field, `GET /sibling`, exact route order and reset-before-sibling-response ordering. All nonterminal suffix bytes are consumed. A skipped rejected block would instead lose dynamic state and fail the sibling decode/head assertion. Invalid-opening controls remain in the complete original corpus and still never route. + +| Transcript | Required stream 1 error | Deferred route order | Started route order | Full suffix bytes | +|---|---|---|---|---:| +| content-length-data | PROTOCOL_ERROR (1) | 3 | 1, 3 | 144 | +| malformed-trailer | PROTOCOL_ERROR (1) | 3 | 1, 3 | 126 | +| closed-data | STREAM_CLOSED (5) | 3 | 1, 3 | 126 | +| stream-window-overflow | FLOW_CONTROL_ERROR (3) | 3 | 1, 3 | 129 | +| half-closed-head | STREAM_CLOSED (5) | 3 | 1, 3 | 153 | + +Existing scalar diagnostics and test-local lifetime guards provide actual event order, without production instrumentation.

Started application wait: `admitted:1,started:1,cancelled:1,token-completed:1,destroyed:1,admitted:3,started:3`. Each started handler has exactly one destruction and one typed token completion (`cancelled`); its exchange disconnect reason is `connection_closed`. A late application signal executes no cancelled code. Three incomplete-body controls separately allow exactly one failed body-read completion (`connection_closed`), then one destruction and token cancellation. This is failure delivery before the next owner reap, not stale signal reentry; the body does not respond after failure. + +Every variant requires exact RST_STREAM scope/code/count, no GOAWAY, complete suffix consumption and zero usage of all 13 resource kinds after engine/executor/route teardown. Connection-error controls require one GOAWAY, final output ordering, sticky failure and no duplicate output. Compression-error precedence remains in the unchanged `peer-reset-invalid-hpack`/`closed-invalid-hpack` entries.

No configured executor memory store was found; reusable setup facts are recorded below. + +## Verified cause and interface decision + +The fresh task-local configured `make -C build/task192/normal-off/test cookie_render` exits 2: no target. The source/install manifests contain no v3 cookie header or implementation. The legacy suite depends on removed v2 classes and fluent setters. The inventory and TASK-179 guide claimed a standalone helper while migration documentation delegated parsing/rendering to applications. The authorized repair supplies the bounded helper and keeps all three named capability-054 witnesses. + +[Interface comparison and doubts](TASK-192-design-evidence.md) compares a validated fluent class, an owned aggregate with explicit operations, and a fields adapter on depth, locality and seam placement. Chosen: owned `http::cookie`, `parse_cookie_header(string_view) -> vector`, and `render_set_cookie(cookie, string&) -> outcome`. The current public tree contains no reusable generic `result` for this synchronous helper, so no generic result framework was introduced. Rendering validates every raw construction path before atomically replacing output; applications append successful values as ordinary repeated fields. No v2 request/response hierarchy, shims, cookie jar, automatic policy or parse cache is restored. + +The historical v2 implementation at `f5d7e9e8^:src/cookie.cpp` confirms SP/HT-only token/name trimming, first-equals splitting, one outer quote pair, untrimmed leading value whitespace, malformed/empty-name omission, preserved case/empty values/percent bytes and lenient interior controls. The helper preserves those observable rules. Rendering preserves exact Expires/Max-Age/Domain/Path/Secure/HttpOnly/SameSite order, signed Max-Age, and None implying Secure. It rejects CR/LF/NUL/semicolon, invalid names, comma-bearing Domain/Path and invalid enum values. Typed outcomes replace fluent setter/exception shapes. Expires now explicitly rejects times outside civil years 0000..9999 rather than relying on platform-dependent `time_t` conversion; migration documentation records this real change. C++20 civil date arithmetic and fixed English names require no locale, timezone or OS date APIs. + +## Behavioral RED/GREEN and clearing doubts + +Evidence root: `build/task192`; unique journal path is recorded in `build/task192/journal-path`. + +- Public declarations and a no-behavior scaffold permit behavioral RED: `/usr/bin/clang++-18 -std=c++20 -Isrc -Itest test/unit/http_cookie_test.cpp src/cookie.cpp -o build/task192/cookie-red`, then execute. `cookie-red.log`: 9 cases / 69 checks / 35 expected failures. The empty parser, unchanged rendering and missing typed rejection fail actual assertions; missing-header compilation alone is not counted. +- `cookie-green.log`: 9 cases / 129 checks, zero failures/skips. Ownership is tested after overwriting/destroying input and clearing the original vector. First-equals/quotes/malformed tokens and raw controls are pinned. The CR witness first asserts the exact parsed name/value retains CR, then requires `invalid_argument` and unchanged output. All four construction fields exercise CR/LF/NUL/semicolon rejection; parsed LF/NUL, invalid names, comma attributes, enum, signed-age extrema, SameSite, epoch/negative/leap/boundary dates and int64 overflow are covered. +- `runner-red.log`: 31 Python tests / 10 failures demonstrating accepted unrelated commands/suites/missing executable/hash/log/count proof. `runner-green.log`: 31 pass. `runner-count-red.log`: 32 tests / six failures on mismatched success totals, ordinals and duplicate summary/failure/skip records. `runner-count-green.log`: 32 pass. +- Runner mutation fixtures intentionally use synthetic bytes/logs; the positive contract executes the actual current cookie suite, retaining command/suite/case identities, executable and log hashes, completion markers and aggregate test/check counts. Full parity uses real freshly built binaries, including libtool wrapper resolution and the explicit peer_policy taskset invocation. The behavior-wire special witness remains intact. +- Linear token scanning and one owned pair per nonempty token bound parser storage by admitted input, without cache/global state. Existing HTTP field budgets govern input. Rendering builds a local string after validation. All named public-interface doubts are cleared by the final native, provenance and installed wire receipts below. + +## Local verification + +Four fresh C++20 Clang 18 configurations use `--disable-examples`, `-std=c++20 -pthread -O1 -g -fno-omit-frame-pointer`. TLS-on selects genuine OpenSSL 3.5.9 at `/home/etr/progs/libhttpserver/build/tooling/provider`, with include and library/rpath flags plus `-lssl -lcrypto` in `V3_TLS_LIBS`. ASan/nonrecovering UBSan adds `-fsanitize=address,undefined -fno-sanitize-recover=undefined -fsanitize-address-use-after-scope`, with `ASAN_OPTIONS=detect_leaks=1:detect_stack_use_after_return=1:halt_on_error=1` and `UBSAN_OPTIONS=halt_on_error=1:print_stacktrace=1`, outside ptrace. No suppression or disabled diagnostic. Lanes also run with `TZ=Pacific/Honolulu`, `LC_ALL=C`; rendered dates remain GMT. + +`run_lanes.py` and each lane's `lane-receipt.json` retain exact configure/build/execution commands, environment, exits and durations. Library builds precede explicitly selected targets. The selection covers cookie native/consumer/public wire, ordered semantic fields/request heads, H1 response framing/outbox, response definitions, header hygiene, native linkage and Littletest result/skip checks; pinned Python runner/client contracts and check-local/install-layout/distribution gates follow. + +An initial task-local provider selection put -L/rpath in `V3_TLS_LDFLAGS`, which configure regenerates from `V3_TLS_LIBS`; those configure failures are retained under `initial-lane-attempts` and corrected without production changes. A concurrent normal-off contract invocation captured the intentionally failing count RED before GREEN landed; its log is retained and the lane rerun after the fix. Historical TASK-185 evidence is untouched. + +All four lane receipts pass. Each executes 11 native programs: nine ordinary Littletest suites total 143 cases / 886 checks / zero failures/skips; a separate framework skip-semantics contract intentionally reports 4 cases / 2 checks / 2 skips and exits successfully, and the standalone native linkage probe exits zero. The three cookie programs alone total 12 cases / 141 checks with zero skips. Final runner contracts execute 32 Python tests in each lane using that lane's actual cookie binary; client contracts execute three Python tests. Final wire fixture cleanup removes an unused admin-address branch and directly asserts stopped state after all throwing wire/lifecycle predicates. + +`lane-final-summary.json`, `native-final-counts.json`, each lane's `runner-final.log` / `wire-final.log` and `distribution-contract.json` retain current results. Changed C++ cpplint, Python syntax and whitespace checks pass. The inherited unused `parse_one` warning in unchanged `http1_response_outbox_test.cpp` remains outside this helper repair. Initial check-local executions followed the repository's explicit missing-Doxygen skip. The retained genuine Doxygen 1.9.8 tool at `/tmp/task183-tools/doxygen` was then found and both normal TLS configurations executed the real zero-substantive-warning gate. Missing optional Graphviz initially caused map-file errors; the final documented command passes `HAVE_DOT=NO` through `DX_ENV`, with no source warning suppression. Initial logs are retained under `initial-lane-attempts`. + +The first complete normal run executed all 92 commands / 168 golden observations / 90 supporting witnesses, but correctly failed stale input hashes after the verified malformed-proof repair. A subsequent normal receipt passed before the final cookie mapping/fixture cleanup. The first complete sanitized run likewise completed all observations and correctly rejected stale inputs after those final bounded edits. These are retained as diagnostics; only the final fresh-input receipts below serve as completion proof. + +Additional checker RED/GREEN: `runner-malformed-red.log` reports three malformed proof-type exceptions (None/list/string); `runner-malformed-green.log` passes all 32 tests after treating non-record proof as invalid evidence. The final capability-054 mapping explicitly cites the actual typed helper/API and bounded-date migration instead of a generic request/source rationale. + +## Complete final parity receipts + +Both complete parity executions and independent final receipt checks pass against current inputs. `final-summary.json` retains the complete source/input hash map and exact cookie supporting/cell records; each final directory contains the authoritative receipt and every command log. + +| Final receipt directory | Commands | Native executions | Native cases/checks | Golden observations | Supporting witnesses | Capabilities/cells | +|---|---:|---:|---:|---:|---:|---:| +| `parity-normal-final2` | 92 | 78 | 957 / 16024 | 168 | 90 | 60 / 360 | +| `parity-asan-final` | 92 | 78 | 957 / 16024 | 168 | 90 | 60 / 360 | + +Each receipt has 344 applicable cells (152 preserved, 192 explicitly documented migrations) and 16 justified not-applicable cells.

Separate installed raw-wire consumers supply actual managed/external TCP observations. + +## Installed and wire proof + +The public `consumer_v3_cookie_wire` uses only installed public library headers plus copied test-side Littletest/host-poll support and its own independent raw TCP client. Both managed and external readiness scenarios observe exact repeated Set-Cookie values and ordering for multiple request Cookie fields/pairs, empty values, case, first equals, percent bytes, GMT date and SameSite=None. The injection scenario retains CR-bearing parsed data, requires typed rejection before append, and observes one 422 response, no Set-Cookie field or second message, actual EOF, and orderly server/readiness cleanup. Scenario predicates throw on failure; Littletest records two stopped-state assertions after completed wire/lifecycle checks, not a fabricated count of internal predicates. + +`installed_cookie.py` stages fresh normal TLS-off/on packages under an invocation-unique `/tmp/task192-cookie-package-*` prefix and copies consumer sources/support to an invocation-unique `/tmp/task192-installed-cookie-*` directory. The final probe explicitly rejects every compiler include path beneath the source/worktree root, so neither package headers nor copied test support come from source/build include paths. Compiler commands include only the installed include directory, no source/build include paths, compilation macro, private/provider header or v2 library. Shared consumers link the identified staged `.so`, static consumers the explicit `.a`. `installed-cookie-receipt.json` retains compile/run lines, actual library/executable hashes, dependency logs and counts. Final installed execution covers both consumers against shared and static libraries in both TLS configurations (eight successful runs). An initial unscoped TLS-on install spent its bounded staging interval building unrelated noinst fixtures; its timeout log is retained. Final staging scopes TESTS/check_PROGRAMS/noinst_PROGRAMS together, as planned, and all real consumer predicates still execute. Semantic consumer: 1 case / 10 checks. Wire consumer: 2 cases / 2 scenario checks; both exercise actual installed native runtime. + +## Scope, remaining ownership and archival + +BSD/macOS/Windows and nonlocal backends are unexecuted and CI/v3-PR owned under AGENTS.md. TASK-200 retains timer/manual-executor teardown race ownership.

The final installed receipt identifies both isolated directories and 26 successful compile/dependency/run/staging commands. Earlier in-tree installation iterations are diagnostic only; strict final proof uses these fresh outside-tree prefixes. Setup memory: bootstrap Autotools; configure VPATH builds; build src first; targeted Makefile programs/Littletest assertions live in test/unit, test/headers and test/integ; public consumer CPPFLAGS omit HTTPSERVER_COMPILATION; provider -L/rpath belongs in V3_TLS_LIBS.

Shared runtime identity/resolution and actual instrumentation symbols are retained in `tsan-adapter-runtime-graph.log`. + +ASan/UBSan runs with nonrecovering diagnostics, `detect_leaks=1`, `detect_stack_use_after_return=1`, use-after-scope enabled and halt-on-error. TSan runs outside ptrace with halt-on-error and no suppressions. Library and installed public server consumers are instrumented; independent provider-only clients remain separately identified tooling. + +| Frozen installed public lane | Receipt directory | Shared/static × managed/external | +| --- | --- | --- | +| Normal TLS-on | `public-normal-on-repair1` | 4 × 82 scenarios | +| ASan/UBSan TLS-on | `public-asan-on-repair1` | 4 × 82 scenarios | +| TSan TLS-on | `public-tsan-on-repair1` | 4 × 82 scenarios | +| Normal TLS-off | `public-normal-off-repair1` | 4 same-source cells | +| ASan/UBSan TLS-off | `public-asan-off-repair2` | 4 same-source cells | +| TSan TLS-off | `public-tsan-off-repair1` | 4 same-source cells | + +All six receipts pin the same source identity `0656f8818c550af469b2c1fe614a4f57ec3ca560f28a88de0022de56a59179b0`. TLS-off cells execute the original14 configuration checks plus five public runtime/ACME/key checks. The 984 TLS-on scenario executions retain all23 TASK-193 cases and add59 explicit authentication/retirement/rotation/ACME/example cases. Public server applications compile outside the source/build tree against installed headers/pkg-config without provider/private headers or `HTTPSERVER_COMPILATION`. Shared/static link graphs, dependency files, link maps, library/header/compiler/client/fixture identities are retained. The independent OpenSSL client includes no libhttpserver headers and its runtime graph excludes libhttpserver. + +Independent TLS1.2/1.3 mTLS tests verify chain/hostname, actual fingerprints in both exchange and request hook, complete body/ALPN, valid/absent/untrusted clients and zero handler entry on rejection. Bound profile downgrades fail; multiple leases and concurrent bind/replace have deterministic public regressions. PSK witnesses assert actual version/cipher/ALPN/body, selected host/generation/finite callback deadline and version translation, exact binary1.3 identity, empty/oversized keys, oversized identities and redacted exception failure. Held callbacks outlive timeout/peer close/stop/drain; cancellation and late accepted keys never route. Caller handles and input material are dropped while a held callback remains alive. Fixed active/queued capacity survives four rotations, queued expiry never enters the callback, and capacity recovers after actual retirement. Healthy handlers acknowledge stop/drain while another callback remains blocked; explicit retirement reports timeout until release and callback self-wait returns would_deadlock. Two servers sharing a runtime remain independent when one stops. + +Ordinary same-host/generation TLS1.2/1.3 session reuse is proven with reuse flags and omitted certificate messages. Host/store isolation remains separately tested. Replacement now uses a distinct trusted certificate valid for the original `a.example` SNI: the independent client retains its original session while proving reuse before publication at the same endpoint and ALPN, then requires reused=0, a full Certificate message and the exact replacement fingerprint. An established connection completes requests before and after that publication in both TLS versions. All twelve installed TLS-on cells execute these witnesses. An accepted incomplete handshake retains its old certificate through replacement; an established keepalive socket remains useful while fresh sockets select the new certificate. The installed listener example serves three complete held-connection requests plus two verified fresh requests across valid and rejected replacement. External PSK and ACME disable ticket/session resumption. Real TLS1.3 early request bytes are transmitted by the independent client, rejected by the server, and never cause an extra handler invocation. + +ACME selection uses authentic `127.0.0.1:443`: exact/canonical SNI and sole `acme-tls/1` present the supplied certificate fingerprint, sole DNS SAN and unique critical digest DER/value. Wrong/absent SNI, wrong port, mixed/no/HTTP ALPN cannot select it. Normal HTTP stays chain/hostname verified. Eighteen malformed SAN/digest/certificate/key/expiry candidates reject and preserve the installed challenge; encrypted/malformed/mismatched keys are included. Actual absolute expiry rejects fresh handshakes; removal is canonical/idempotent, selected incomplete challenge handshakes remain pinned, and three concurrent normal/publish/remove writers finish coherently. Normal mTLS/PSK authentication never leaks into a selected challenge. + +Ordinary real443 binding was refused with EACCES, including escalation. Root and executor verified a bounded genuine client/server roundtrip in a disposable user/network namespace. The matrices run through `unshare --user --map-root-user --net` with loopback enabled only inside that namespace; each positive receipt asserts actual local port443. No production predicate override, host sysctl, persistent capability or host-network change was used. + +New critical negative witnesses include absent require-mTLS, untrusted optional mTLS, wrong PSK identity/key, invalid callback result bounds, queued-expiry/cancellation counters, wrong-port/SNI/ALPN ACME and attempted early-data zero-handler assertions. The fail-closed inventory rejects missing, duplicate, unknown and false-success cells. Initial harness failures are preserved: source-tree prefix contamination, exact negative TLS1.3 EOF classification, explicit interactive-client termination, immediate-stop response cancellation and real-clock expiry margins. An accidental duplicate insertion of the PSK-bound probe into ACME tests failed and was removed. These attempts are not positive evidence. + +Local packaging verification includes both `check-local` lanes, header hygiene/install layout/native linkage, strict TLS-off/on package audit and clean installed-consumer matrix, runner27/package35 contract tests, changed-file default cpplint, whitespace and distribution/new-file content checks. The distribution SHA-256 is `e3ff434e16d9a1b5464a6efc6870470d8909d11fb57dcdfce4e2d15f9bbb5cc3`. Doxygen is unavailable locally and its repository gate explicitly assigns execution to CI. Final package receipts are recorded in the machine receipt. + +The clean installed-consumer run retained an unrelated host-clock rollback failure in static TLS-on `native_http1_e2e::digest_stale_nonce_rechallenges`: the original log contains negative -990.286ms and -5716.6ms durations. The exact unchanged executable then passed all60 tests/708 checks twice. `build/task194/resume-package.py` preserves that failure, verifies unchanged artifact/dependency identities, runs only unfinished installed suites/public traffic/audit steps, and writes a separate final summary under `/tmp/task194-package-final-lvij4ht5/matrix/resume-clock-rollback`. No nonce/auth/time assertion or production code was changed. Final package receipts compare both strict audits and identical41 header declarations. + +All eight design doubts are cleared by the named installed witnesses, policy/retirement regressions, owner/sanitizer receipts and dependency audits. No post-handshake client auth or PSK-on-H2/H3/QUIC capability is claimed. Public H2/H3 and benchmark tasks195..199, independent timer teardown200 and aggregate185 gates retain their owners. TASK-200's race was neither encountered nor edited. BSD/macOS/Windows and nonlocal backends remain unexecuted locally and are CI/v3-PR owned under AGENTS.md. No validation-loop, merge, cleanup, push, tag, publication or deployment was performed. + +Reusable project notes: bootstrap then VPATH configure with Clang18/C++20, explicit provider flags only for TLS-on; build src before bounded Automake selection and set TESTS/check_PROGRAMS/noinst_PROGRAMS together. Stage src plus root install-pkgconfigDATA into an external prefix. Static TSan strong allocator overrides can use the standard shared runtime per executable without losing fault probes. Real443 requires the disposable loopback-enabled namespace route here. Mature registry retirement must destroy user captures outside writer locks. + +Validation repair iteration 1 reproduced rejected candidate callable destruction under the registry writer lock: the bounded public regression aborts after five seconds (`rejected-retirement-red.log`). The locked helper now borrows an outer shared owner; replace, ACME publish and ACME removal retain candidate and retired snapshot ownership until after the writer guard is released, including rejection and exception exits. The public regression verifies typed invalid_argument, completed reentrant destructor, preserved listener policy and subsequent writer progress (6 tests/78 checks), while retaining the successful-retirement regression. Normal/ASan/TSan owner lanes pass. `same-host-rotation-red.log` records the previous installed consumer rejecting the missing same-host command before the new witness was implemented. Original receipts/evidence are preserved under `build/task194/repair-original`. ASan owner and TLS-off installed ptrace failures are retained; exact owner artifacts replay outside the sandbox with detect_leaks=1 and unchanged diagnostics. Refreshed strict current TLS-on/off audits retain identical public declarations; nonlocal checks remain CI/v3-PR owned. diff --git a/specs/architecture/v3/TASK-194-implementation-receipt.json

After a successful enabled certificate/mTLS ALPN selection of +`h2`, it owns `http2_tcp_owner`. No public server or provider API is added, no +live socket is moved to another listener record, and no private fixture enters +the production transport. TLS-off and public H3 remain rejected before bind. + +The H2 owner composes the existing engine and native read/write/wake/timer +operations. Its serial `http2_dispatch` processes one queued invocation per +worker turn; parser turns retain their existing frame quantum. Input suffixes +survive yields. Only one write borrows the immutable engine output, and only +the actual transferred bytes advance it. Existing CONTINUATION and exposed +control retirement remain the protocol engine's responsibility. + +Each admitted stream owns a separate serial affinity on configured workers. +That affinity exclusively owns the exchange, handler frames, lifecycle hooks, +resume state and completion/destruction. The wire owner alone touches HPACK, +stream maps, windows, pending frames and deadline anchors. Handler-side +respond/start/upgrade prepares owned bounded state in one semantic slot before +publishing acceptance. The owner applies that state in stream order. Terminal +publication has an independent path; resetting a queued stream closes its +entry gate before it can invoke application code. Resetting a running stream +queues cancellation behind the active resume and retains every frame until it +returns. Cancellation never concurrently writes the running exchange. + +The body stream uses fixed rings and short stream-local locks. Read/write +waiter publication and owner progress notifications happen after unlocking. +An atomic consumed counter transfers exact application consumption to the +owner; receive/send windows remain owner state. Published failure references +refer to immutable outcomes, avoiding a reference race during terminal +publication. Request trailers are exposed only after the handler sees EOF; +response trailers are immutable once finish is published. + +The scheduler has sixteen bounded work slots and a separate overflow terminal +callback. Progress callbacks coalesce owner work. Queued capture destruction +happens outside the scheduling lock. An overflow closes the stream/connection +through its terminal callback, rather than silently dropping a live decision. +No owner or stream lock spans hooks, application code, executor post, external +readiness dispatch or destruction of user captures. + +Server → listener → connection → stream budget children copy and clamp parent +capacities. Stream seats, request copies, rings, response fields/trailers and +WebSocket codec storage belong to the stream child. Parser/HPACK/control and +one active output frame belong to the connection. Header staging reservations +transfer into admitted stream state without a reservation gap. Existing TLS +admission and retiring provider work retain their leases. Bounded reserves are +made before synchronous acceptance; refusal propagates through typed failure +and lifecycle cancellation. A full semantic queue produces terminal failure. + +`next_deadline` inventories absolute SETTINGS/header, stream body-idle, +suspension, write-idle, WS close and native drain deadlines. The native watchdog +arms the actual earliest timer and cancels/rearms only when its governing +deadline changes. Header block completion clears its anchor after parser frame +release; otherwise an otherwise idle completed HEADERS frame could incorrectly +expire the connection before the stream body timer. Body idle starts at body +admission, and output advances the write anchor only on actual transfer. No +periodic polling timer is added. + +Native H2 streams count in the server drain scope. A stream affinity publishes +the counted drain identity, so handler waits return `would_deadlock`. Stop is +nonblocking. Drain stages GOAWAY, refuses openings beyond the accepted cutoff, +lets accepted work finish and expires remaining requests/WS through the same +terminal path. Tickets outlive server destruction and retain the original +incomplete result and remaining count after deadline expiry. Connection +finalization waits for transport loop and actual stream retirement. + +Certificate/mTLS ALPN binding tracks H1.1 and H2 eligibility transactionally. +Live publication cannot enable a protocol disabled by an attached listener. +PSK retains H1-only policy. TLS1.2 H2 rejects prohibited CBC ciphers before +request hooks. Existing ACME exact SNI/port/ALPN isolation remains enforced. + +Alternatives refuted by the plan and retained RED: one shared handler/wire +executor lets a running handler stall controls; substituting a worker pool +violates exchange cancellation affinity. A global protocol mutex would hold +unrelated streams behind application code. The chosen private owner plus +stream-local semantic handoff preserves the public synchronous API and shared +route/lifecycle services. The original serialized private-engine mode remains +available for deterministic corpus and H3-shared helper users. + +The implementation evidence maps each doubt to behavioral RED/GREEN and the +installed independent matrices. Local Linux gates own normal and sanitizer +proof; BSD/macOS/Windows remain explicitly CI/v3-PR owned under AGENTS.md. + +Required H1 parity verification also exposed a shared terminal-publication race: +shutdown published an ordinary disconnect flag before its immutable reason, and +H1 read the final disconnect state after relinquishing its lifetime lock. The +minimal common repair publishes a copyable atomic flag after the reason/body/ +writer metadata and snapshots final H1 disconnect state under the existing +connection lock. It preserves public value/move semantics and adds no shared +protocol lock. A terminal-response/resume-versus-shutdown regression proves +exactly-once completion under TSan; H2 affinity cancellation remains unchanged. diff --git a/specs/architecture/v3/TASK-195-implementation-evidence.md b/specs/architecture/v3/TASK-195-implementation-evidence.md new file mode 100644 index 000000000..3606a3e5a --- /dev/null +++ b/specs/architecture/v3/TASK-195-implementation-evidence.md @@ -0,0 +1,98 @@ +# TASK-195 implementation evidence + +Implemented on `task/TASK-195` from clean v3 +`eb4bf441a0aafc1a651959947f7a5f490d12dbdc`, reusing the registered +`.worktrees/TASK-195` and preserving its interrupted implementation and receipts. +The private ownership boundary is documented in [TASK-195-design.md](TASK-195-design.md). +The implementation commit is the commit containing this document.

Independent clients are Python hyper-h2 4.4.1 and Node +24.15.0/nghttp2 1.68.0; CA/hostname verification is enabled. Public compilation +uses installed public headers outside the repository, with audited dependency +files, link maps, shared/static graphs and exact library/header/tool/fixture +hashes. All three TLS-on matrices validate their complete inventory and unchanged +covered inputs. The public example is also installed, compiled and exercised. + +ASan/UBSan runs outside ptrace with leak detection, stack-use-after-return/scope +and nonrecovering diagnostics.

Supplemental +H3 exchange/drain suites protect the shared serialized handler helper without +claiming public H3 support. + +## Causal closure + +The journal `.debug/task195/journal.md` and all original task-local receipts +remain intact.

Stopped driver separately returns `invalid_state`. Rollback and mixed-listener public predicates also pass. | +| Shared H1 shutdown publishes partial disconnect metadata | Exact `.debug/task195/tsan-h1-parity-original.log`; one equivalent retained TASK-194 baseline replay passes without disproving the timing race. `h1-retirement-red2.log` causally exposes reason publication. Minimal atomic publication/lifetime snapshot repair passes all required H1/H2 normal/ASan/TSan gates. | + +Fixture failures remain distinct from library fixes. Node drain-finish keeps a +second accepted upload open through both required GOAWAY stages because +node:http2 otherwise retires its last completed stream before the barrier PING; +both stages and accepted completion remain asserted. A clock discriminator +recorded wall=15307ms versus monotonic=9737.8402ms at the false 12s SETTINGS +observation failure, before the native 10s deadline. Node bounds now use +`performance.now()` with identical durations and wire assertions. The initial +ASan H1 nonce expiry failure and negative wall-clock durations are preserved; +unchanged replay and the complete final 76-suite ASan run pass. + +One original ASan installed fixture stack receipt was overwritten before this +resume. The journal honestly retains the observed driver-reference +stack-use-after-scope diagnosis and the lost-receipt limitation; the independent +original external crash JSON and corrected ASan replay remain. No original +stack is reconstructed or represented as preserved. + +BSD/macOS/Windows and other nonlocal platform checks are unexecuted here and +owned by CI/the v3 PR under AGENTS.md. TASK-200 timer/manual-executor teardown, +public H3, benchmarks, release orchestration and unrelated worktrees remain +outside this implementation.

A TCP and UDP entry may share a fixed numeric port. Ephemeral entries allocate independently. H3 without UDP, UDP without H3/TLS, invalid enum values and incompatible credentials fail before binding. Duplicate address/port/transport entries fail regardless of their TLS bit. Binding is transactional: activate every endpoint only after all binds succeed. + +The alternatives were automatic dual binding from a global H3 bit (ambiguous resource/port reporting and implicit sockets) and a separate public QUIC factory (duplicated routes/credentials/lifetime). Explicit transport retains the existing server and route API while exposing the actual socket choice. Public mixed and rollback witnesses discriminate these choices. + +`quic_udp_listener` owns UDP receive, admission, CID dispatch, one shared atomic writer and timer scheduling. `quic_network_connection` owns serialized TLS/key/identity, recovery, flow, H3 framing and close state. These compose mature private engines. Extraction excludes fixture file serving, capture/key observers, manual executors, environment profiles and test constants; production has no test-support dependency. + +Each native H3 request has an independent `http2_dispatch` stream affinity and route executor. The synchronized semantic rings carry admitted body/response bytes; a mutex-protected single owned response command carries copied fields. The wire domain applies commands and exact consumed counters. Handler suspension, running frames and cancellation never own the QUIC wire domain. Native RFC9220 returns typed `not_supported`; full parity belongs to TASK-197. Existing serialized private H3 remains the default for protocol fixtures. + +A single serial wire/application loop was rejected by the held-running-handler and held-upload sibling discriminators. General worker callbacks mutating protocol state under a shared lock were rejected because arbitrary application work would retain the protocol lock. Native stream ownership follows TASK-195 instead of introducing a cross-protocol runtime. + +Admission uses Retry before connection allocation, pending64/32768byte limits, reply16 and a bounded128-route CID/retired history. Each listener prepays131072bytes for admission/dispatch/I/O storage and one timer. Connection storage prepays separate data and critical393216byte envelopes (smaller public limits reduce them), one connection seat and one timer.

Child budgets preserve server aggregate capacities and independent critical pools. + +Preparation burns packet numbers and owns immutable bytes/debit. Only actual atomic UDP completion commits sent offsets/recovery/pacing. Proven-unsent returns the debit; ambiguous completion conservatively consumes it once. CID dispatch stores nonowning sinks, avoiding an owner/registration cycle. Alias routes, cached protected close output and keys survive the real three-PTO endpoint and pending completion. Stream frames and their scopes survive until affinity retirement; request drain units are distinct from protocol linger. + +`request_stop()` claims terminal state and wakes owners immediately. `stop()` keeps backend, workers, routes/hooks/policy and credentials alive until protocol expiry and completion. Managed mode drives existing backend work. External mode first disables application dispatch, waits for any dispatch claim to finish and exclusively drives bounded native poll/timer turns using real monotonic time. The public driver stays inactive thereafter. Immediate backend destruction and a detached global reaper were rejected: the former frees callback services early, the latter adds an unrelated runtime with user-reference hazards. + +TLS binding is transport-aware. Public certificate stores accept H3; UDP requires an enabled default H3 selection. TCP and QUIC filter their own protocols while sharing immutable material. Initial installation and live replacement use the same compatibility function. QUIC uses TLS1.3, QUICv1 and disabled0RTT. PSK stays HTTP/1-only; ACME is never selected for QUIC. Actual listener port is propagated to credential/provider context. Comprehensive rotation, saturation and staged drain remain TASK-197; benchmarks TASK-198/199 and separately retained timer teardown TASK-200. + +The causal journal and implementation evidence retain RED/GREEN commands, setup failures and all local proof obligations. Nonlocal BSD/macOS/Windows belong to CI and the v3 PR under the repository policy. + +## Named discriminators and provider retirement + +The behavioral journal is retained under `.debug/task196/journal.md`; raw commands and receipts are under `build/task196/`.

Detached worker `live==0` precedes thread-local destruction; the deterministic C++ destructor witness fails `drain(!early)` on the original lane. A future-only alternative passes that witness but fails a warmed POSIX TLS-key destructor witness: promise readiness can precede OpenSSL-style native thread-local cleanup. An unconditional native join would violate a deadline-bound drain when that destructor is held. Root selected the planner addendum's provider-only lane observer after those counterexamples. One observer is precreated before any provider worker; it owns and joins at most64 handles, releases them and publishes native-provider-retired in plain synchronized state. It captures no lane/provider/application values. Startup failure seals registration and cancels already-started workers without joining the constructing caller. Application lookup workers remain detached and independent. stop/destruction never join; drain waits only until the original monotonic deadline and can be retried after a held native destructor releases. The maximum runtime envelope adds one observer to the existing64 provider plus64 lookup workers, with one fixed handle vector. Unexpected join failure fails retirement; detach is the nonterminating fallback, with bounded handle preservation if the OS also refuses detach. A successful drain proves provider workers' actual native exit, not the observer's short plain C++ publication tail. Current-prefix normal/ASan/TSan preservation and384 fresh immediate-exit processes pass without sleeps after success or new suppressions. This finding is separate from TASK-200's retained timer/manual-executor condition-variable teardown race. + + +The native H2 preservation gate also exposed a send-completion ordering defect: +the peer can ACK the staged-drain PING before the native writer resumes and +records its successful send. The connection retains at most one exact matching +ACK for the active offered PING. It publishes barrier acknowledgment only after +successful complete output advancement, clears pending ACK on partial advancement +or terminal failure, and retains the existing premature-partial-ACK rejection. +The deterministic full/remainder offer ordering RED and failed-offer discriminator +pin this repair without adding a transport runtime. + +TASK-197 owns comprehensive migration accounting. In +`quic_network_connection::credit_datagram`, received bytes currently credit the +original `facts_.budget`; after application path validation, the application path +can instead use `identity_->application_budget()`. The original/shared path uses +the same budget, and the newly validated path is not amplification restricted. +This observation concerns migrated-path receive accounting and credit/budget +recovery; TASK-196 does not claim comprehensive migration coverage or an +unvalidated-path amplification proof from the basic public matrix. TASK-197 must +verify the original/shared versus newly validated path distinction under its +existing migrated-path policy/metadata and recovery action items. + + +Authenticated terminal close precedes path activation and application effects. +After successful packet authentication to this connection, an unvalidated +candidate path can carry CONNECTION_CLOSE without becoming the application path. +Co-packed STREAM cannot execute, send/amplification restrictions remain, terminal +notifications occur once and real expiry owns final retirement. Forged ciphertext +cannot close the connection. Production and the affected capture fixture share +this ordering; independent protected-client RED/GREEN tests and current native, +public and capture sanitizer proofs cover it. + +Capture observation retains every live challenge/response predicate. An unanswered +challenge retires only when an independently authenticated matching zero-error +client close precedes its arrival, with the same close packet identified at both +boundaries and no later server STREAM. No missing/unmatched/undecoded close or +challenge-before-close can receive this treatment. The original failure remains +retained and fails the unchanged TASK191 server closure oracle. + +The task-local pinned ns3.46.1 simulator derivative changes only the elapsed-time +clock and period in WallClockSynchronizer to steady_clock. Origin and now retain +one nanosecond domain; relative waits, original limits, loss/rebind scenarios and +all scenario binaries remain unchanged. Exact upstream archive, minimal patch, +compiler/build and original/derived image/binary identities are recorded in the +clock receipt. A real original-image pacing RED and120-event patched-image proof +run under observed host realtime backsteps. This compatibility affects only the +explicitly selected simulator; host, application, client and protocol clocks are +unchanged. Full proof verifies its provenance and the unchanged nine-stage gate +inventory, including exact compiled-input scope when reusing completed checks. diff --git a/specs/architecture/v3/TASK-196-implementation-evidence.md b/specs/architecture/v3/TASK-196-implementation-evidence.md new file mode 100644 index 000000000..f7314fe40 --- /dev/null +++ b/specs/architecture/v3/TASK-196-implementation-evidence.md @@ -0,0 +1,140 @@ +# TASK-196 implementation evidence + +Implemented in the helper-resolved `task/TASK-196` worktree from clean v3 +`e83857afe708e6c9fdb713df2868bf91f962062d`. The implementation commit is the commit +containing this document. Task status remains In Progress; caller Groundwork +validation, archive, completion bookkeeping, merge and cleanup remain pending. +[The design](TASK-196-design.md) records the actual ownership choices and limits. + +Explicit provider-neutral UDP listener entries now compose production QUICv1, +TLS1.3 and basic H3 with the existing public server, credentials, routes, hooks, +policy, metadata and hierarchical budgets. TCP remains the aggregate default; +TCP and UDP identities can share a fixed port. Validation precedes all binding, +and all endpoints activate transactionally. Public certificate policy accepts H3 +and filters TCP/QUIC bindings independently; external PSK remains H1-only. + +Production composition contains no fixture serving/capture/manual-executor/profile +or test-support dependency. Each request runs on an independent stream affinity, +with an owned bounded command and synchronized body/output rings. Protocol wire +owners retain storage, reliable information, aliases and close keys through +actual atomic send settlement, pending completions and real three-PTO expiry. +External stop exclusively drives native completion/time progression after +application dispatch has become inactive; request_stop stays immediate. + +The journal `.debug/task196/journal.md` and raw `build/task196/` evidence retain +behavioral REDs, all failed attempts and their exact replays. Machine identities, +final gate receipts and local/external artifact directories are recorded in +[TASK-196-receipt.json](TASK-196-receipt.json) and `build/task196/handoff.json`. + +Final local proof comprises all nine existing full transport/capture/corpus/fuzz stages; +normal, ASan+UBSan and TSan installed H3 matrices (each four TLS-on and four +TLS-off cells); the preserved H2 matrix in all three modes; six TLS policy +matrices; and eight strict package cells per sanitizer mode. Each independent +H3 client proves seven traffic cases plus 19 configuration/lifetime predicates +in every TLS-on cell. Bounded immediate-exit H2 repetition passes 128 fresh +processes per mode, 384 total, without success sleeps. Broad native coverage +passes 81 TLS-on and 21 TLS-off suites in each mode; the final stream-tail +repairs refresh eight affected TLS-on suites and six TLS-off suites in all six lanes and deterministic +8-test/39-check normal/ASan/TSan closure. Exact hashes and reuse scope are in the receipt. + +Required causal closures include explicit mapping/rollback, actual installed +public routing, independent held-running/upload siblings, copied-field lifetime, +listener/connection/stream storage, actual emission settlement, CID cycle and +expiry retention, exclusive external retirement, and exactly-once asynchronous +admission for retransmitted Initial. Both independent pinned clients authenticate +through installed public-only shared/static managed/external consumers; the +public fixture is not the private transport endpoint. + +A required H2 preservation gate exposed provider native retirement before real +TLS destructor exit. C++ TLS and warmed POSIX TLS destructor REDs refute both a +logical live count and future-only readiness. An unconditional caller join is +also invalid under a held destructor and finite deadline. Root explicitly selected +one precreated provider-only lane observer. It exclusively joins at most64 provider +handles and publishes plain completion after releasing them; it captures no lane, +provider, TLS, application or callback references. Provider drain preserves the +original steady deadline, request_stop/destruction never join, and arbitrary PSK +lookups remain detached and independent. Fixed startup fault, last-owner, +held-unrelated-lookup and invalid-handle witnesses cover ownership boundaries. +Successful drain proves all provider workers' native exit; it does not claim the +observer's own short plain C++ tail has natively exited. Immediate process-exit +ASan/TSan witnesses test that remaining limitation without success sleeps or +suppression. + +The final H3 TSan destruction witness also exposed an affinity closure keeping +a retired semantic stream alive after the engine state lease was released. +The destructor redundantly accessed the expired owner to complete already +completed hooks. A deterministic ASan RED reproduces this exact use-after-free. +The destructor now skips owner-dependent completion after native retirement; +private/incomplete cleanup retains its previous completion path. Normal/ASan/TSan +prove exactly one completion, safe engine-before-affinity destruction and inert +late resume, and all final installed H3 matrices pass. + +The full H2 family additionally exposed two distinct issues. An unchanged +TASK-195 TSan disconnect replay reproduces a consumer taking only a listener +snapshot between connection completion/rearm, then terminating during exception +unwind with a joinable host thread. Snapshot capture now requires a real live +connection registration; exception cleanup reveals the actual assertion while +retired-generation dispatch and zero-accounting checks remain. Separately, +matching drain PING ACK can arrive before asynchronous successful write completion +is recorded. Deterministic full/remainder offer REDs fail twice; GREEN retains one +exact active-offer ACK until full successful send, while partial and failed sends +cannot acknowledge the barrier. Both GOAWAY stages and the original deadline +remain required. + +Required retained QUIC capture checks exposed a real authenticated terminal-close +bug on a newly observed candidate path: the original client-boundary close +preceded a last challenge, and the server continued emitting STREAM after that +same authenticated close. Production and the affected fixture now consume a valid +close before path activation or application frames. Protected independent-client +RED/GREEN tests retain forged-packet rejection, unchanged path/accounting, +exactly-once terminal notification and silent expiry; normal/ASan/TSan native and +real interop/capture replays cover the repair. A challenge is excluded from the +response obligation only when exact authenticated matching zero-error close +preceded its arrival at the client boundary. Both boundaries must match the close +packet; the server no-STREAM-after-close oracle remains mandatory. Missing, +unmatched, forged, undecoded or erroneous closes and unanswered live challenges +fail closed. The original failure remains rejected by the unchanged TASK191 oracle. + +The pinned quic-go semantic drain client also exposed the previously documented +TASK191 unread-buffer/remote-close race after its genuine accepted-FIN ACK. Its +client-only tracer now holds submission of that already constructed covering ACK +until the application consumes its original accepted response. It changes no ACK +contents or server timing, and the original five-second context bounds the wait. +Both GOAWAY stages, late-request refusal, accepted response contents and remote +close remain required; independent captures prove actual wire ACK before server +retirement. Race unit tests and actual normal/ASan/TSan matrices pass. + +The retained simulator is provisioned explicitly as a patched-clock derivative +of the original pinned image, with all scenario/entrypoint files unchanged. Host +CLOCK_REALTIME was observed stepping backwards about7.34 seconds every5.3 +monotonic seconds; the exact pinned ns3.46.1 synchronizer used system_clock for +origin and elapsed pacing. Root authorized one task-local compatibility patch: +only that synchronizer's clock/period becomes steady_clock. Exact upstream +archive, source revision, original binary, patch, compiler, build, derived image +and binary hashes are retained. An unmodified-image pacing RED and a120-sample +100ms patched-image proof distinguish the clocks under actual host backsteps. +Exported symbols remain identical. No global clock spoofing, host mutation, +client-clock changes, altered scenarios, original test-limit extension or capture +predicate waiver is used. Final nine-stage evidence labels this tool provenance +and verifies exact covered inputs when reusing completed native/fuzz proofs. + +Normal/ASan/UBSan/TSan libraries and installed consumers use Clang18/C++20 and +selected OpenSSL3.5.9. Sanitizers run outside ptrace with leaks, stack diagnostics, +nonrecovering UBSan and halt-on-error; no new suppressions. The existing named +request_lifecycle allocation-count TSan exclusion remains, with full normal/ASan +proof. External adapter allocation probes retain their executable-specific +shared-libsan setup. Strict installed-package audit probes use static sanitizer +runtime so no undeclared shared runtime is accepted. + +Static gates compare the clean v3 baseline honestly: seven preexisting CPD groups, +three untouched size offenders, and unchanged/reduced complexity offenders; no +new or increased offending function. Overloaded complexity matching includes the +full signature. Actual retained Doxygen1.9.8 runs with Graphviz disabled because +absent and unchanged warning filters. The new API heading warning is repaired. +Pinned PMD7.24.0/JRE21 provisioning identities are retained in the machine receipt. + +TASK-197 owns full H3 parity, RFC9220, rotation, staged drain and the precisely +recorded migrated-path receive-accounting observation. TASK-198/199 own benchmarks; +TASK-200 owns the separately retained timer/manual_executor condition-variable +teardown race. Nonlocal BSD/macOS/Windows checks remain unexecuted and CI/v3-PR +owned under AGENTS.md.

Application handlers run +on independent stream affinities. A bounded owned command transfers an RFC9220 +opening response and driver/session to the serialized H3 wire owner; it never performs +QUIC/QPACK mutation in an application worker. Opening fields and resource reservations +survive the handoff. The receive half remains available for WebSocket DATA. Reset, +disconnect, timeout and drain cancel suspended receive/writable operations before the +handler frame and leases retire. Close deadlines start on the actual close transition. +Receive RESET and send STOP_SENDING remain independent even after semantic cancellation: +a late STOP still prepares exactly one RESET_STREAM with the actually emitted final size. + +Ordinary HTTP response handling would abandon the upgrade receive half. Direct worker +mutation would put user handlers in the protocol serialization domain. The existing H2 +owned-command model avoids both problems without introducing another runtime. + +One application stream seat covers framing and semantic ownership. QUIC flow retirement +requires terminal receive state and reliable FIN/reset acknowledgement; handler return +alone cannot replenish transport capacity. Retiring transport records drops heavy receive +and send storage, accepts authenticated late credit/retransmission without recreating +work, and preserves a bounded 64-entry lifetime identity record. H3 admits at most 16 +live requests. This fixed lifetime capacity is deliberate and does not promise unlimited +requests on one connection. Critical control/recovery capacity remains separately reserved. + +Whole authenticated datagrams credit the identity's current application budget exactly +once, including a distinct validated migrated path. Initial precredit is preserved. Policy +is checked at admission, candidate discovery and activation; an accepted exchange retains +its copied peer identity while subsequent work sees the validated current path. A rejected +claimed admission remains in the existing bounded expiring table to prevent repeated hooks +for retransmitted Initial. No unvalidated path becomes an application path. + +Aggregate drain keeps weak UDP listener owners alongside weak TCP owners, so deadline +cancellation reaches all listeners without creating a scope cycle. Admission completing +across the drain transition cannot publish a new connection. Failed H3 GOAWAY initiation +retains the original deadline. Application drain counts remain distinct from three-PTO +protocol retention, alias keys and pending atomic datagram completion. Handler initiation +returns promptly; waiting on a ticket counted by that handler returns `would_deadlock`. + +Native H3 advertises the actual bounded QPACK table and blocked-stream capacities +(4096 bytes and eight sections). Installed independent clients withhold real encoder +instructions, decode cancellation/refusal and prove healthy siblings before release. +The bounded loss/reordering witness is a one-peer test datagram relay retaining at most +one 2048-byte packet; it neither decodes nor injects server protocol state. + +Common public `100-continue` admission exposed an H2 omission. Successful admission +publishes a bounded informational command. Informational HEADERS do not mark final +HEADERS sent or permit DATA before the final head. The independent aioquic 1.3.0 +witness has a test-only adapter resetting its header parsing state after a decoded 1xx +section, because the pinned implementation otherwise classifies the final HEADERS as +trailers. The installed package has no independent-client dependency. + +Credential selection uses the existing immutable public store generations and QUIC +provider adapter. Initial mTLS, SNI, independent stores, held Finished across rotation, +existing/new connections, resumption and genuine rejected early-data attempts remain +public wire observations. ACME selection is TCP-only. PSK/H3, invalid ALPN and +post-handshake client authentication fail before publication/listening. + +The installed consumer and native example compile from installed public headers and +libraries only, for shared/static linkage and managed/external loops. Public semantic, +RFC9220, aggregate drain and credential receipts supplement the retained nine-stage +transport/conformance proof. BSD, Windows, macOS and other nonlocal checks remain +owned by CI and the v3 PR. Validation/finalization and Git publication are runner-owned. diff --git a/specs/architecture/v3/TASK-197-implementation-evidence.md b/specs/architecture/v3/TASK-197-implementation-evidence.md new file mode 100644 index 000000000..bb422310d --- /dev/null +++ b/specs/architecture/v3/TASK-197-implementation-evidence.md @@ -0,0 +1,95 @@ +# TASK-197 implementation evidence + +Implementation remains on `task/TASK-197`, based on `v3`, in its registered isolated +worktree. No staging, commit, merge or worktree lifecycle action is performed by the +executor. Task status remains In Progress pending the runner's validation/finalization. + +The behavioral journal is `.debug/task197/journal.md`. Retained raw RED/GREEN receipts +are under `.debug/task197/`; resumed probes are `/tmp/task197-*.log`. Final package and +conformance receipts are under `build/task197/`. `TASK-197-receipt.json` records actual +completed gates and artifact hashes; failed earlier attempts remain distinguishable. + +Behavioral regressions cover native upgrade handoff and immediate DATA, cancellation +of pending receive/writable, copied opening fields/charge, reliable stream retirement, +late retransmission/credit, one stream seat, migrated-budget accounting, admission across +drain, failed GOAWAY deadline and admission-hook deduplication. A final wire cancellation exposed receive RESET +arriving before STOP_SENDING: semantic cancellation had incorrectly suppressed the +independent send RESET. A deterministic two-order regression fails the missing action +and passes after transport RESET preparation precedes the semantic idempotence guard. +The public pending-writable witness now forces acknowledged receive RESET and handler +retirement before sending STOP, then requires the decoded remote RESET. Resumed H2 regressions +first failed missing informational HEADERS and DATA emitted before final HEADERS; +`http2_native_owner` passes with bounded continuation publication and informational +head scheduling. The public one-shot source corpus first failed with 404, then proved +file/pipe exact bytes, second-use 409 and exactly one handle close on H1/H2/H3. + +Public witnesses retain raw ordered fields/trailers, normalized routing, authentication, +fragmented forms and byte limits, multipart cleanup, concurrent immutable cursors, +borrowed buffers/reopenable and one-shot files/pipes, committed exception reset and +100-continue before upload. H3 partial borrowed/file cancellation actually exhausts +4096 bytes of stream credit, retains the lease while blocked and proves release/close +and coroutine retirement after decoded peer cancellation. Partial multipart creates an +actual temporary file and proves cleanup after cancellation. Held credential rotation +withholds a real client Finished flight after selecting the old certificate. + +The installed matrix includes both pinned clients (aioquic1.3.0/quic-go0.55.0), the +public native example RFC9220 corpus, same-port TCP/UDP, four-listener aggregate tickets, +blocked QPACK, loss/reordering counts, three download/upload reset/refill cycles and six +one-second CPU/RSS observations. Normal allocator RSS limits apply only to normal lanes; +sanitizer lanes still require measured idle CPU thresholds and exact ownership witnesses. +No timeout or process-exit-only result substitutes for a decoded remote terminal. + +Setup transfer bounds distinguish normal throughput from sanitizer instrumentation: +warm download uses normal3s/instrumented8s, and impaired recovery uses normal6s/ +instrumented12s. Receipts require measured positive elapsed times within those bounds. +Exact TSan probes showed continuous bytes and FIN at 4–5s warm and 6.19s impaired; +earlier short-deadline failures remain retained. The six fixed one-second stalled CPU +windows, normal allocator RSS limit, impairment counts, ordered bytes/FIN and decoded +terminal predicates retain their original thresholds. + +The unchanged standalone `http3_websocket_handshake` allocation-counter test cannot +link with TSan's strong new/delete interceptors. It passes fully under normal/ASan; +native negotiation, immediate DATA, upgrade/reset and destruction remain covered by +`http3_native_stream` within the thirteen affected TSan owner suites. No new sanitizer +suppression or linker override is introduced. The GOAWAY deadline unit test now mocks +only its own clock/decoder, preserving subprocess's real clock; actual decoder/network +gates remain unchanged. + +Compile/setup mistakes, wrong fixture options, client timeouts, stale aggregate libraries +and source mutation during an earlier matrix are retained as failed attempts, not accepted +production RED or final evidence. Source libraries are rebuilt before test relink/install. +The historical missing upstream runner/simulator receipt was restored by shared tooling; +the task uses that genuine pinned infrastructure without replacing the required proof. + +Nonlocal platform receipts are deferred to CI / v3 PR under repository policy.

No old +sample is represented as a fresh measurement by the repaired producer. The +repaired producer separately passed a fresh TLS-on reduced smoke with all 16 +cells and 16 requests per cell (256 total). Its first preflight attempt selected +system Python without the pinned clients and failed; that attempt is retained. +The retry selected the existing pinned client environment. + +The source summary records the verification receipt, repair RED/GREEN logs and +new smoke. Distribution is refreshed into a separate `-repair` archive with +extracted runner help and focused contracts; the original archive is preserved. +The existing evidence checker verifies recorded identities plus the explicit +bounded-equivalence proof, while the public validation API continues to reject +any mismatched expected identity. Resource/installed protocol results retain +their original valid receipts because measured inputs and production policy are +unchanged.

`ff83e59653a8657f040975ccf4fe2c58462dbedf`. Implementation is ready for caller-owned +Groundwork validation/finalization. No staging, commit, merge, worktree operation +or TASK-185 runner edit was performed. The [machine receipt](TASK-199-implementation-receipt.json) +and [current report](../../../test/installed/task199-capabilities.md) retain the +specific proof boundary; [the adapter interface](../../../docs/v3-packaged-release-adapters.md) +provides TASK-185's two callable families and independent validators. + +The initial execution below is retained as historical implementation evidence. +The validation-repair receipt added to the machine receipt records renewed +public execution from the repaired archive; reduced benchmark execution remains +separately identified with its original archive and unchanged covered inputs. + +## Initial distribution and installed execution + +The initial frozen integration archive is `/tmp/task199-dist-build4/libhttpserver-3.0.0.tar.gz`, SHA-256 +`75cfe738dd0857f4be9c347d9db36c170007c67dc4dbcfb47c8ca9f25b5f50a1`; its extraction has no `.git`. The implementation executable +adapter/consumer sources matched their distributed members before validation repairs. Documentation and +this receipt were reconciled after execution, so the archive does not contain +its own generated evidence. The final distribution check separately verifies +all newly registered files. + +Autotools bootstrap/configure and fresh optimized C++20 builds use Clang 18 and +normal allocators: `CXXFLAGS='-O2 -DNDEBUG'`, `--disable-examples`, explicit +`--enable-v3-tls=no|yes`, and the selected OpenSSL provider.

The initial host bind rejection is preserved; +no port substitution or injected metadata supplies proof. Every final family +returns zero and a new-process `--validate OUTPUT/receipt.json` with the same +input/run-ID/workload arguments returns zero. All artifacts, archive inputs, +consumer directories and staged packages remain available for revalidation. + +## Initial RED/GREEN and integrity gates + +RED preceded adapter implementation, caller run-ID propagation, supported +configuration parsing, installed H1/WS support, copied/private provenance +rejection, and identity/protocol/JSON strengthening. The machine receipt lists +retained `/tmp/task199-red*.log` and matching GREEN logs. Later bounded probes +causally exposed configuration/profile log collisions, a lazy H2 binding missing +from H3 aggregate/semantic execution, HTTP status versus scenario status parsing, +and missing selected-client catalog/source references. Each has a focused +regression and a fresh successful final archive execution. Earlier failed +attempts and their source/install snapshots remain preserved. The temporary +`task199-parser-discriminator-only.json` was a synthetic parsing discriminator; +it is explicitly excluded from accepted integration evidence. + +All 138 focused tests pass: installed package (35), installed consumer (28), +package workflow (4), public H2 (6), public H3 (13), benchmark (18), adapters (34). +The dependency-free adapter contracts also pass via Automake's dedicated log +target. Changed C++ files pass cpplint; Python compilation and whitespace checks +pass. No production backend-size cleanup was introduced. + +Both fresh builds pass: + +```sh +make -C BUILD check-v3-native-linkage check-headers check-hygiene check-v3-installed-package-fixtures +``` + +Independent strict installed-package audits return no violations, including +unused archive members. Their header sets/effective declaration hashes agree +for all 41 installed headers. Rejection copies are independently rehashed, +so scenario/statistic/process rejection is semantic rather than a stale catalog +hash. The original accepted outputs remain unchanged. Six tampering outcomes +are retained in `/tmp/task199-tampering-final/results.json` and this machine receipt. + +## Handoff and ownership + +TASK-185 can update from `v3`, import the archive's adapter module, call +`run_public_capabilities(inputs, output, run_id)` and +`run_native_benchmarks(inputs, output, run_id, workload)`, then use the supplied +independent validators with recomputed expected identities. Its exact runner +interface is absent here; TASK-185 owns that final wiring. A reduced benchmark +cannot replace a full performance gate. Historical TASK-179 descriptions, +receipts and unavailable-at-the-time classifications remain unchanged. + +TASK-182 is already Complete in both card and index; no status transition was +invented. TASK-199's implementation action items are checked, while its status +remains In Progress for caller validation/finalization. TASK-185 stays open. +BSD/macOS/Windows checks are honestly unexecuted locally and belong to CI/v3 PR. +Existing local sanitizer/resource/release requirements remain unchanged. + +## Validation repair iteration 1 + +Seven validator-authorized findings were repaired without staging, commits, +merges or TASK-185 changes. RED produced 23 expected semantic rejection failures +in `/tmp/task199-repair-red.log`; the retained no-second-receive executable still +passed the original live gate (`/tmp/task199-repair-ws-red.log`). The repaired +gate rejects both that original mutation and a freshly compiled mutation with +valid eight-field counters and a close callback but no `/cancel` receive. The +original foreign-first static link also rejects. Exact logs, assertions and +semantic repair receipts are retained in the machine receipt's +`validation_repair` section. + +The repair archive is `/tmp/task199-dist-repair/libhttpserver-3.0.0.tar.gz`, +SHA-256 `4f5327a740d9d1e4ae21548a8d82c5b45ff498daa50498829309b1c655345626`, +extracted without Git at `/tmp/task199-extract-repair/libhttpserver-3.0.0`. All +changed executable adapter/test/consumer sources match distributed members. +Documentation and generated receipts were reconciled afterward. Production +library sources and installed package hashes remain unchanged; the existing +optimized TLS-off/on builds and installations supply the selected libraries. + +Both full public matrices were executed anew: `/tmp/task199-repair-public-no` +(run ID `19900000000000000000000000000041`) and +`/tmp/task199-repair-public-yes` (run ID +`19900000000000000000000000000042`). TLS-on uses an isolated network namespace +with loopback enabled and authentic TCP443. Each outer adapter exits zero and +its independent new-process `--validate` exits zero. All eight H1/WebSocket +cells record pending receive entry, actual `connection_closed` completion on +peer EOF, and retirement before stop. `cancelled_receive` counts this actual +transport termination; it does not claim an `outcome_code::cancelled` result. +A preliminary independent-validation harness incorrectly used system Python +instead of the selected venv, failed its module check, and was corrected; the +failed attempt remains explicitly separate from the accepted validations. + +Forty adapter, 28 installed-consumer, 18 benchmark, six H2 and 13 H3 focused +tests pass (105 affected contracts). Adapter Automake, C++ cpplint, Python +compilation and whitespace checks pass. Thirty-five independent child-semantic +mutations plus six blank-readiness process mutations reject after catalogs and +child artifacts are rehashed, preserving the original accepted outputs. They +cover both TLS modes' required family provenance, H1 versions/multiplicity, +WebSocket receive retirement, and contradictory TLS credentials, callbacks, +SNI, session rotation and ACME observations. + +The original reduced benchmark receipts are preserved under their original +archive identity and independently revalidated with the repaired checker. All +298 recorded benchmark source inputs are unchanged in each lane. No new +benchmark measurements, full performance gate or nonlocal execution is claimed. +TASK-185 retains final wiring and release acceptance; CI/v3 PR owns nonlocal +platform checks. diff --git

The preceding focused selection passed seven other programs. The unchanged base comparison passed four cases and 2002 checks; that isolated pass did not resolve the intermittent finding. A fresh normal baseline here also passed four cases / 2002 checks / zero skips, exit 0. + +## Demonstrated boundary and ownership + +The regression interposes the actual queue-mutex unlock and `std::condition_variable::notify_one` call using Linux/libstdc++ linker wrapping. It discovers the queue mutex by observing `pending()` unlock, then gates only foreign producers unlocking that mutex. The shipped executor and coroutine/timer code execute unchanged during RED. No hook, constructor, global test state or macro enters a production header. + +The controlled timeline is: + +1. The actual timer callback wins the resume-node claim and posts the actual coroutine resumption. +2. The queue item is inserted; the producer completes the real queue unlock and pauses immediately after it. +3. The owner drains that item. The coroutine returns the checked timeout outcome exactly once, its completion callback runs on the borrowed executor, and `run_pending()` returns after frame destruction. +4. The owner attempts retirement and invokes losing signal/cancel triggers. No further queue item appears. +5. The producer is released. Unchanged production executes a real executor notification **after** the retirement attempt. GREEN executes none after that attempt. +6. A callback on the same serial timer thread acknowledges producer/callback exit before executor and probe storage are actually destroyed. + +The signal-winning and cancel-winning variants first gate the real timer service, arm a zero deadline, publish from an explicit producer thread, then observe the same retirement boundary. Cleanup releases and joins that producer and releases the timer gate. A serial timer fence acknowledges processing of the losing cancelled deadline. Both variants observe exactly one publication, one checked result, correct executor affinity and no work/continuation after frame retirement. + +This proves the **post tail** hypothesis: queue publication allowed completion to become observable before the final executor-member access. The late losing-producer hypothesis is excluded for these completed one-shot waits by the real cancelled deadline, repeated losing triggers and the publication/work counts. The old six-millisecond grace period did not acknowledge either producer completion or executor access and could not establish safe destruction. + +RED keeps the executor alive until all producers exit, even when checks fail; it observes the unsafe ownership boundary without intentionally inducing undefined destruction. All assertions follow producer cleanup. Atomic gates establish ordering; five-second limits only diagnose deadlock. A timeout still releases the producer. Signal threads are joined, and timer fences retain captured state until the callback has exited. + +## Behavioral RED and GREEN + +The same focused regression command was run before and after the production repair: + +```sh +/usr/bin/clang++-18 -std=c++20 -pthread -O1 -g -fno-omit-frame-pointer \ + -DLHS_TEST_POST_TAIL_WRAP -DLHS_TEST_POST_TAIL_ONLY -Isrc -Itest \ + test/unit/task_race_test.cpp \ + -Wl,--wrap=pthread_mutex_unlock \ + -Wl,--wrap=_ZNSt18condition_variable10notify_oneEv \ + -o build/task200-implementation/{red,green}-regression +build/task200-implementation/{red,green}-regression +``` + +The brace alternatives identify the two separate invocations, not a single compiler command; executed paths are also recorded in the journal. + +| Version | Cases | Checks | Failures | Skips | Exit | +| --- | --- | --- | --- | --- | --- | +| RED, unchanged executor | 2 | 35 | 3 | 0 | 3 | +| GREEN, repaired executor | 2 | 35 | 0 | 0 | 0 | + +All three RED failures are `late_notifications == 0`, observed **1** instead: timeout, signal and cancellation each demonstrate the same tail. After refactoring the timer fences to retain their promise by shared ownership through callback return, the final regression was also compiled against the unchanged executor extracted from the base commit (`red-include/httpserver/concurrency/executor.hpp`): `red-replay` again exited 3 with two cases / 35 checks / three identical failures. Final GREEN again exited 0 with 35 successes. All six configured lanes were rerun after that fixture refinement. Initial instrumentation wrapping `pthread_cond_signal` did not intercept the shared libstdc++ notification and was rejected as a discriminator. The corrected full RED additionally encountered the existing scheduler-dependent stress assertion demanding both outcome classes. Focused RED separated the three causal failures from that unrelated count. + +## Repair and contract implications + +`manual_executor::post` now notifies **inside its existing queue lock**, before unlock makes the work available to a consumer. Its final executor access precedes publication. This is a one-line relocation plus an ownership comment. Retaining the unused condition-variable member preserves the public class layout; removing it would unnecessarily change layout. There is no public signature, constructor, shutdown contract or ownership change. + +Timer cancellation still makes pending entries inert; it does not wait for already-running callbacks. Callback waiting is unnecessary for the demonstrated notification tail and would introduce self-cancellation/inline-resumption lock-order concerns. Frame witnesses, executor lifetime leases, borrowed executor references, executor-affine resumption, exactly-once claims and typed outcomes remain unchanged. Borrowing does not promise automatic ownership of arbitrary application executors or safe destruction with unrelated posters still active. + +The old timeout stress family retires without its six-millisecond teardown sleep. It explicitly seeds one already-signalled wait and one genuine deadline-only wait, preserving both outcome checks and **198** real deadline-versus-signal races. Scheduler luck no longer determines whether both outcome classes receive coverage. The two deterministic regressions also run in the ordinary `task_race` target under **TSan**, outside the allocator-hook exclusion. + +`consumer_v3_timed_resume` is registered/distributed through Automake. It uses only public concurrency headers, exercises real timed completion and signal/cancellation winners, checks typed result, affinity and exactly-once completion, repeats losing triggers and retires without a grace sleep. Existing executor and umbrella consumers retain their header-hygiene coverage. + +The linker probe is available on Linux/libstdc++; `configure` enables only the test target's flags when that library is detected. Other platforms/standard libraries report the two probe cases as named skips; equivalent nonlocal instrumentation is CI/v3-PR owned. All required local lanes execute both regressions with **zero race-case skips**. No production dependency or race suppression was introduced. + +## Required local verification + +Toolchain: Ubuntu clang **18.1.3**, C++20.

The runner must retry +validation; this record does not claim review approval or task completion. TASK-200 +remains In Progress on `task/TASK-200`. Changes are unstaged and uncommitted for the +runner-owned commit flow. No Groundwork skill, publication, merge, or next lifecycle +step was invoked. + +## Cause and repair + +`manual_executor_post_probe.hpp` previously published a raw pointer to stack +storage. Every intercepted mutex unlock read that pointer before deciding whether +its mutex matched. An unrelated timer-service reader could retain it beyond the +owner's deactivation and scope exit. A serial timer callback promise acknowledges +earlier callback processing, but does not retire every unrelated wrapper reader. + +Discovery now uses C++20 `atomic>`. Each wrapper holds a +strong reference before its first dereference. The thread-local producer also +holds a strong reference across the post tail and notification wrapper; the +existing joined-thread and serial-timer cleanup paths clear it. The capture +pointer remains confined to its owner's synchronous mutex-discovery call and is +cleared before publishing the initialized probe. Probe mutex identity and owner +are immutable after publication, and the remaining shared fields are atomic. + +The local libstdc++ implementation in +`/usr/include/c++/13/bits/shared_ptr_atomic.h` uses an atomic reference-count lock +bit for shared-pointer load/store. Its unlock uses atomic operations, and its +spin relaxation uses processor pause or scheduler yield +(`bits/atomic_wait.h`). These operations do not recursively call the wrapped +pthread mutex unlock. Both TSan lanes execute this protocol without diagnostics. +The helper is enabled only for the existing Linux/libstdc++ interposition target. +No production code, API, executor ownership contract, or suppression changed. + +## Deterministic regression and preserved production discriminator + +`probe_lookup_retains_retired_publication` arms a reader-local gate immediately +after wrapper discovery and before its first publication dereference. The reader +unlocks an unrelated mutex; while it is paused, the owner clears discovery and +drops its last strong reference. A weak reference proves the reader still owns +the publication. The fixture then releases and joins the reader and proves the +publication has been destroyed. Assertions follow thread cleanup, and the gate +storage remains alive through the join. Bounded waits diagnose stalled progress; +no sleep, retry, grace interval, or sanitizer suppression supplies ordering. + +| Check | Exit | Cases / checks / failures / skips | +| --- | --- | --- | +| Reported bounded audit reproducer with raw stack discovery | 1 | ASan stack-use-after-return at its first dereference | +| New regression with raw discovery, ASan/UBSan | 1 | 3 / 39 / 1 / 0; retained-ownership assertion fails | +| Repaired fixture, ASan/nonrecovering UBSan | 0 | 3 / 39 / 0 / 0 | +| Repaired fixture against unchanged base executor | 3 | 3 / 39 / 3 / 0; exactly the original timeout, signal, and cancellation late-notification failures | + +The new RED assertion uses a weak reference to observe retirement deterministically. +The weak reference keeps the allocation's control block available, so that RED +is a behavioral lifetime failure, not a claim of a second ASan memory diagnostic. +The separately reproduced original stack case confirms the unsafe dereference. +An initial sandboxed RED execution also reported the ptrace LeakSanitizer +limitation; the retained RED receipt is the subsequent outside-ptrace execution +with leak checks enabled.

The tracked original implementation receipt remains historical; +its per-test paths in the reused trees now contain the recovery runs. + +| Lane | Programs | Harness cases / checks / skips | task_race cases / checks / skips | Installed consumers | +| --- | --- | --- | --- | --- | +| normal-off | 11/11 | 60 / 5823 / 0 | 7 / 2041 / 0 | 3/3 | +| normal-on | 11/11 | 60 / 5823 / 0 | 7 / 2041 / 0 | 3/3 | +| asan-ubsan-off | 11/11 | 60 / 5823 / 0 | 7 / 2041 / 0 | 3/3 | +| asan-ubsan-on | 11/11 | 60 / 5823 / 0 | 7 / 2041 / 0 | 3/3 | +| tsan-off | 11/11 | 60 / 5811 / 1 | 7 / 2041 / 0 | 3/3 | +| tsan-on | 11/11 | 60 / 5811 / 1 | 7 / 2041 / 0 | 3/3 | + +All steps exit 0.

Executive summary + +v3 is a C++20 embedded server whose HTTP/1.0, HTTP/1.1, HTTP/2, HTTP/3, QUIC, and WebSocket engines are owned by libhttpserver. Protocol engines convert wire events into one request-scoped `exchange`; routes, hooks, authentication, request bodies, responses, and errors operate on that semantic exchange. The production library has no libmicrohttpd dependency. A TLS-disabled build has no third-party runtime dependency beyond platform and C++ runtimes. A TLS-enabled build uses one OpenSSL 3.5 LTS provider for TLS, X.509, randomness, and QUIC packet cryptography; libhttpserver owns QUIC transport and HTTP/3. + +The canonical handler is `task(exchange&)`, with a clearly named bounded synchronous value-returning route adapter for small endpoints. An exchange reaches a terminal response or WebSocket upgrade once. Awaitable reads and writes expose backpressure; cancellation and application resume signals wake suspended work. A reusable response definition is immutable and replayable, while each send owns a fresh cursor and request-specific fields. HTTP/3, all required WebSocket modes, certificate replacement, and ACME TLS-ALPN-01 gate v3.0, not a later release. + +## 2. Drivers and constraints + +| Driver | Architectural response | +|---|---| +| One route across enabled HTTP versions | RFC 9110 semantic request/response model above distinct wire engines | +| No MHD; no runtime dependency except optional TLS provider | Owned parser, codecs, scheduler, QUIC, WebSocket, auth, forms; OpenSSL isolated privately | +| Bounded memory under slow/malicious peers | Hierarchical limits, admission, per-stream credit, bounded queues, timeouts, fair scheduling | +| External loop and four OS families | Private operation-oriented I/O boundary; internal epoll/kqueue/IOCP and fallback poll; public readiness adapter | +| Safe public lifecycle and ownership | Header-time decision, typed results, stop request separate from drain wait, explicit body-resource leases | +| v2 behavior parity with full API break | Behavior inventory and migration matrix; no v2 ABI or source shim | + +The existing Autoconf/Automake packaging remains the initial v3 build path; build/test tooling may add dependencies but installed headers and production binaries obey the runtime rules. C++20 and a new SOVERSION remain. No cloud service, persistent store, auto ACME client, WebSocket extension, h2c, or unspecified future HTTP version is part of the server. + +## 3.

State-changing operations from handlers return to the connection owner. Shared route tables, IP policy, hooks, and TLS snapshots publish immutable generations so readers need no global hot-path lock. This is a target responsibility split, not a direct transplant of v2's MHD callback services. + +Peer policy implements this split with an atomic `shared_ptr` owning both pattern vectors, enabled state, mode and derived armed state. A writer mutex serializes read-modify-publish operations against the latest generation, preventing lost independent updates. Parsing happens before serialization. Each reader retains one owned generation through both scans; no reader-held shared mutex spans the scan. Atomic shared-pointer operations are not promised to be lock-free. The scalar `armed()` acquire load remains the unused-policy gate. Writers release-publish the generation before release-storing that gate; after passing the gate, classification acquire-loads a generation and checks its own armed state, including disabled acceptance. Overlapping calls may use an older complete generation; operations synchronized after a completed mutation observe the published update. + +Candidate construction leaves the previous generation intact on failure. Pattern mutators retain their existing throwing allocation behavior and typed invalid-pattern outcomes. The existing `noexcept` mode/enabled setters now allocate to copy a generation: allocation failure terminates, rather than silently dropping an update. These setters already offered no recoverable failure channel for synchronization failures. Generation lifetime is bounded by the current publication and in-flight readers; the policy introduces no reclamation queue or custom hazard-pointer scheme. TASK-188's bounded progress, independent-writer and installed listener evidence pins this publication contract. + +### 3.1 Public semantic interface (illustrative, not final signatures) + +```cpp +using handler = unique_function(exchange&)>; +result server::route(method, path_pattern, handler); +result server::route_sync(method, path_pattern, + value_handler, body_limit); +const request_head& exchange::head() const; // raw_target, route_path, method, + // protocol, ordered fields, TLS/peer metadata +result exchange::admit_body(body_policy); +task> body_reader::read(byte_sink); // bounded; trailers after EOF +task> body_reader::collect(size_t maximum); +task> exchange::respond(response); // one-shot terminal action +result response_definition::owned_bytes(status, fields, bytes); +result response_definition::reopen_file(status, fields, file_spec); +result response_definition::factory(status, fields, body_factory); +task> exchange::respond(const response_definition&, + response_overlay); // terminal, reusable +result exchange::start_response(status, fields); +task> response_writer::write(bytes); +task> response_writer::finish(fields trailers); +task exchange::upgrade(ws_upgrade_options); +// result owns optional websocket::session and the refusal status/fields. +resume_signal exchange::make_resume_signal(); // application-event suspension +stop_token exchange::cancellation() const; +websocket::send_result websocket::session::try_send(websocket::message_kind, + std::span); // accepted / backpressured / closed +task websocket::session::writable(); +task websocket::session::receive(); +void server::request_stop() noexcept; // nonblocking and handler-safe +result server::begin_drain(deadline); +task drain_ticket::wait(); // rejects a wait from counted handler +``` + +`task` is library-defined C++20 ABI: single consumer, move-only, executor-affine, lazy-start only when scheduled/awaited, with owned coroutine frame. Cancellation completes pending operations once with a typed result; handler exceptions are caught at the route boundary, logged, and converted to a 500 only before headers commit. Once a response is committed, failure resets/aborts the stream or closes the connection as required by the protocol. No exception crosses a socket callback. Handler return without terminal action synthesizes a defined internal-error response. `route_sync` adapts into the same exchange, automatically admits and buffers a body only up to its declared cap, and is documented as unsuitable for unbounded uploads or duplex work. + +Headers and trailers preserve wire order and repeated names. Lookup is case-insensitive by field name; `append`, `replace`, `first`, and `all` have stable semantics. The raw target preserves received bytes; a separately validated and normalized route path is used for matching. `method` and `protocol` are libhttpserver types, including an extension-method value without backend IDs. Semantic content excludes HTTP/1 chunk markers and HTTP/2 or HTTP/3 frame bytes. A route sees complete headers before body delivery, then can reject, admit, await an application signal, or accept a valid upgrade. `Expect: 100-continue` is emitted only after admission. Pre-admission bytes are bounded; rejecting a body either drains a strictly bounded amount or closes/resets as the version permits. + +Only one body read and one response write may be outstanding per exchange. Reads release HTTP/2 and QUIC receive credit only as bytes are consumed. Writes await bounded queue capacity, not peer acknowledgement. A response body source returns data, end, or error through typed results; no sentinel values or backend flags. Cancellation is fanned out to body operations, application suspension, response production, and WebSocket work. An application resume signal is idempotent, thread-safe, and becomes cancelled if its exchange ends; deadlines apply while suspended. + +The owned `http::cookie` value and explicit `parse_cookie_header` / +`render_set_cookie` operations live in the semantic layer (TASK-192). Lenient +parsing preserves raw bytes in owned pairs. Rendering is the single validation +boundary for parsed/directly mutated data and reports typed `invalid_argument` +without changing output. Applications compose repeated Cookie/Set-Cookie values +through ordered fields; no request/response hierarchy or cookie cache is added. +Expires is bounded civil GMT formatting, independent of locale/timezone/platform. +See [cookie design and doubts](TASK-192-design-evidence.md) and +[migration contract](../../../docs/v2-to-v3-migration.md#request-data-forms-and-cookies). + +### 3.2 Response and resource ownership + +An ordinary `response` is one-shot. `response_definition` is immutable and shareable only if its body is replayable: owned bytes, a reopenable file descriptor/path policy, or a factory creating a new source per send. Each send owns serialization state, body cursor, cancellation, and optional overlay fields/trailers. A `response_overlay` owns its ordered headers and trailers; they append after definition fields for that send only, and conflicting singleton/framing fields fail validation before headers commit. Concurrent sends create independent body sources and never mutate the definition or another send. A pipe is a unique one-shot source. File and pipe handles either transfer as `owned_file`/`owned_pipe` or are explicitly borrowed with a lifetime lease; borrowed memory requires a lease spanning send completion. Reuse attempts on non-replayable sources fail before writing. Request-specific overlays never mutate the shared definition. Response framing is selected by the protocol engine. + +### 3.3 Protocol engines and WebSocket + +| Engine | Connection-owned state and rules | +|---|---| +| HTTP/1.0 and HTTP/1.1 | Incremental octet parser, one authoritative message-boundary decision, keepalive/pipelining order, chunking/trailers, `100-continue`, and version-specific close behavior. Reject ambiguous `Transfer-Encoding`/`Content-Length`, invalid lengths, obsolete folding, and malformed field syntax; close where RFC 9112 requires. | +| HTTP/2 | TLS ALPN `h2`, frame and SETTINGS machine, connection-owned HPACK tables and ordered header blocks, per-stream and connection windows, stream cancellation, fair output scheduler, GOAWAY. No h2c. | +| QUIC v1 | UDP connection-ID demux, version negotiation, anti-amplification, path validation and rebinding, packet protection, CRYPTO reassembly, three packet-number-space loss/PTO state, congestion control and pacing, stream reassembly, flow control, and close/drain state. Packet records reference retransmittable information; packet bytes are never replayed as retransmission. 0-RTT is disabled for v3.0; session resumption may remain enabled. | +| HTTP/3 | ALPN `h3`, QUIC streams, one control stream and QPACK encoder/decoder streams per endpoint, connection-owned QPACK and blocked-stream accounting, limits and scheduler priority for critical streams, stream reset and GOAWAY. QUIC v1 is the required wire transport; QUIC v2 is not a v3.0 gate. | + +TASK-165 adds private active-path UDP sizing to recovery. A bounded three-space +transaction applies Initial padding once and commits packet, flow, ACK and +pacing state after one atomic UDP completion. Validated peer/local ceilings +bound standalone PMTU discovery; active-path probe ACKs confirm emitted sizes. +Distinct unsuccessful larger-datagram recovery opportunities trigger a 1200-byte +fallback, preserving retained information, congestion history and pacing debt. +Datagram delivery survives constituent collection, and path epochs isolate prior +feedback. See `docs/task-165-quic-datagram-sizing.md` for policy and evidence. + +TASK-164 implements the private QUIC identity coordinator with four active IDs, +32 cumulative IDs per direction, eight pending retirements and three canonical +path records. It registers aliases before reliable advertisement, validates +sent challenge tokens and minimum-MTU reachability before application output, +and reevaluates live peer policy at discovery and activation. Recovery retains +streams/information across path epochs while resetting RTT/congestion. H3 peer +metadata snapshots at complete initial HEADERS; existing exchanges retain their +copied peer. The bounded TLS network owner exercises this private production +seam; TASK-196/197 now expose it through public H3 listeners. See +[the rebinding evidence](../../../docs/task-164-quic-rebinding.md). + +TASK-166 adds private owner-serialized idle/terminal arbitration with bounded owned +close reasons. Terminal claim cancels H3 requests and provider work once, freezes +identity/path activity, and retains local aliases until the three-PTO endpoint. +Possibly submitted UDP work retains its storage and debit until completion. Closing +uses bounded cached protected close output; draining emits nothing. Peer reset +eligibility requires actual CID use on a remote endpoint, with generation-safe +bounded dispatch fallback for unrelated destination CIDs. Final expiry clears keys +and explicitly detaches aliases without requiring owner destruction. The caller +retains owner lifetime through protocol expiry and pending completions. See +[the lifecycle contract](../../../docs/task-166-quic-lifecycle.md). + +The WebSocket codec consumes an ordered full-duplex byte stream. HTTP/1.1 uses Upgrade; HTTP/2 and HTTP/3 use negotiated Extended CONNECT on one stream. It validates masking, fragmentation, UTF-8, control frames, ping/pong, message limits, and close handshake. A typed session reports accepted/backpressured/closed on `try_send`; pending sends can await `writable()`. The close notification fires once with the best available reason. Extensions are not negotiated in v3.0. A WebSocket on HTTP/2 or HTTP/3 does not take over other streams. + +### 3.4 I/O, concurrency, and external loop + +Private `io_operation` objects describe accept, receive, send, timer, wake, and cancellation completions with storage alive through completion. Native backends use epoll on Linux, kqueue on BSD/macOS, IOCP on Windows, and poll/WSAPoll as fallback and test oracle. Backend delivery order never defines protocol order; the connection owner serializes effects. Readiness backends drain to would-block and rearm correctly; IOCP backends track overlapped-operation ownership. + +External-loop mode exposes opaque socket keys with generations, readable/writable interest changes, a wakeup handle, the next deadline, and nonblocking `dispatch(events, now)`. The application registers interests in its own compatible readiness loop, calls `dispatch` on readiness or timer expiry, then applies the next interest snapshot. Stale generations are ignored. No application handler runs under an internal I/O lock. Dispatch is non-reentrant for a given server; route workers may still execute concurrently. The Windows external-loop path uses readiness registration (for example WSAPoll), while the managed internal loop may use IOCP. + +Limits are hierarchical: server, listener, connection, and stream budgets for connections, streams, header bytes/fields, body buffers, response queues, QPACK/HPACK tables, blocked headers, QUIC reassembly, WebSocket messages, timers, and workers. Admission refuses work before capacity is committed; control-plane processing retains reserved capacity while data flow is backpressured. All public option combinations are validated before listeners accept. Independent protocol capacity profiles resolve once into an immutable startup plan; explicit feasibility and compiled availability are checked before any bind. See DR-V3-006 and `docs/v3-protocol-limits.md`. Timeouts cover handshake, header, body idle, application suspension, write idle, WebSocket close, and drain. + +### 3.5 Lifecycle + +`request_stop()` is idempotent and returns immediately, including from a handler. `begin_drain(deadline)` stops new listener admission and returns a ticket; waiting on that ticket from work counted by the drain reports `would_deadlock`. The state sequence is running → quiescing → draining → stopped. HTTP/1 finishes ordered in-flight work and signals close. HTTP/2 and HTTP/3 issue staged GOAWAY and drain accepted streams. WebSockets send Close, wait until peer close or deadline, then cancel remaining sessions once. QUIC retains closing/draining CID state for the protocol period. Deadline expiry cancels remaining work and reports incomplete work; destruction never silently waits for a handler on itself. + +## 4. TLS, authentication, and security + +The TLS adapter uses OpenSSL 3.5 LTS. Build configuration checks the QUIC TLS callback API; the exact minimum patch release is set against security advisories during implementation and release validation. OpenSSL performs TCP TLS and QUIC's TLS 1.3 handshake/secret exchange. Libhttpserver owns QUIC packet/header protection assembly, transport parameters, and all HTTP engines, using OpenSSL's EVP/HKDF/AEAD primitives. TLS-off builds exclude OpenSSL and reject TLS, HTTP/2, and HTTP/3 configuration with a libhttpserver error before listening; HTTP/1 and WebSocket-over-HTTP/1 remain available. + +Certificate/SNI/client-auth/PSK policy is configured per listener or host before handshake. The TLS registry publishes a validated immutable snapshot atomically; new TCP/QUIC handshakes take the new snapshot, established connections retain their prior context. Default-host behavior, trust roots, mTLS mode, and external PSK identity are explicit. Client certificates are requested at the initial handshake; QUIC post-handshake authentication is unavailable. External PSK is a separate authentication profile from certificate/mTLS where TLS 1.3 cannot combine them. The [external-PSK lookup contract](../../../docs/external-psk-lookup-contract.md) defines the installed internal provider-neutral `psk_lookup(identity, psk_handshake_context) -> psk_lookup_result` callback, captured with runtime ownership in an immutable credential generation. Synchronous provider handshake calls execute on a dedicated bounded handshake lane; application lookup executes on a separately bounded lane, with cancellation and an absolute deadline bounding the trampoline wait. Exclusive session handoff keeps SSL and BIO access away from the I/O owner while a step is outstanding. Owner-side terminal arbitration discards late results, and secure owned keys are wiped at rejection or retirement. Independent handshakes may invoke the callback concurrently. The registry accepts validated PSK-only TLS 1.2/1.3 profiles on HTTP/1 (`http/1.1` ALPN or HTTP/1 fallback), rejecting certificate/trust material, client authentication and other ALPN combinations. TLS 1.2 uses PSK-AES128-GCM-SHA256; TLS 1.3 uses TLS_AES_128_GCM_SHA256/SHA-256 external sessions. PSK profiles disable caching, tickets and renegotiation; selected SNI callbacks and policy are explicitly reapplied. Runtime stop/drain reports incomplete retirement for held application callbacks without an owner-thread join. Per-attempt duplicate results remain bounded secure storage and never form a global key cache. No 0-RTT application data is accepted in v3.0. + +The application supplies a short-lived ACME TLS-ALPN-01 challenge certificate and key (or the data needed to construct them), keyed by exact SNI. The registry validates the name, single SAN, critical ACME identifier extension, key/cert match, and expiry before publication. It selects this credential only for a TCP port 443 ClientHello with exact `acme-tls/1` ALPN and matching SNI; normal HTTP and QUIC ALPN cannot select it. Removal publishes another snapshot; existing handshakes finish safely. Certificate issuance, ACME account management, and challenge orchestration remain with the application. + +Basic and Digest authentication, form/multipart parsing, route and hook policy, IP controls, file delivery, and SHOUTcast have owned v3 equivalents. Digest nonce generation and replay checks use OS randomness and versioned algorithm policy. A TLS-off build implements only the small required in-tree hash primitives for WebSocket handshake and documented Digest algorithms, with published test vectors and differential tests; OpenSSL supplies TLS/QUIC cryptography in TLS-on builds. No user-supplied header or path is reused in a second message-boundary parser. Per-route auth and hooks run at defined phases without gaining access to wire-layer state. + +## 5. Build, observability, and validation + +Installed headers expose no MHD, OpenSSL, OS socket, or backend enum types. TLS-on/off builds expose the same declarations and a feature report; unavailable operations return typed libhttpserver errors. The v3 SOVERSION and migration guide make the complete API break explicit. No MHD headers, binaries, linker flags, or runtime probes remain. Build and package checks run on Linux, BSD, macOS, and Windows (including the project's supported Windows toolchain); a TLS-off package links only platform/C++ runtimes, and a TLS-on package links only OpenSSL's `libssl`/`libcrypto` project as its third-party runtime provider. + +TASK-199 packages the existing public and benchmark runners into exactly two +archive/install-bound adapters. Their versioned receipts pin distributed source, +installed headers/metadata/libraries, provider/tools/clients, complete scenario +inventories and immutable execution artifacts. Independent validation rechecks +actual compile/dependency/link provenance, runtime library selection and decoded +protocol/measurement outcomes. Reduced benchmark integration cannot satisfy a +full workload gate. An optional identity-owned Darwin compiler context pins the +exact independently Clang-selected SDKSettings.json before compilation, rechecks +actual command context and retained bytes afterward, and admits only that +metadata input without weakening package/source/static-contribution gates. +See [the interface](../../../docs/v3-packaged-release-adapters.md) +and [current evidence](TASK-199-implementation-evidence.md). Nonlocal checks +remain CI/v3-PR owned; TASK-185 owns final runner wiring and release acceptance. + +The library emits structured diagnostic callbacks for accept/reject, protocol and TLS errors, stream cancellation, drain, and resource-limit events, without a logging runtime. Optional counters expose active connections/streams, queued bytes, flow-control stalls, handshake failures, and cancellation. Callbacks are bounded/nonblocking or dispatched outside I/O locks; sensitive fields, credentials, and body content are excluded by default. + +Release gates: + +1. Independent-client HTTP/1.0/1.1, HTTP/2, HTTP/3, and WebSocket-over-1/2/3 round trips, multiplexing, loss/reordering, cancellation, flow control, trailers, and drain. +2. RFC conformance, parser differential and request-smuggling corpora, HPACK/QPACK and QUIC state-machine fuzzing, malformed input, and ASan/UBSan/TSan; bounded-memory tests with slow readers and writers. +3. TLS ALPN, SNI, mTLS, PSK profile, resumption with 0-RTT disabled, hot certificate replacement across existing and new TCP/QUIC connections, and exact ACME challenge selection/removal. +4. Public-header and dependency audits for TLS-on/off builds; Linux/BSD/macOS/Windows integration and packaging; external-loop tests for stale events, timers, wakeups, and reentrance. +5. A v2-v3 behavior inventory and executable parity corpus for routing, hooks, Basic/Digest auth, form/multipart uploads, file/pipe/borrowed responses, IP controls, TLS features, WebSocket, and SHOUTcast. Every intentional behavior change receives a migration note. The v2 source API has no compatibility promise. + +## 6. Decision records + +### DR-V3-001: Own the wire engines and use one semantic exchange + +**Status:** Accepted. **Date:** 2026-09-28. + +**Context:** PRD-V3N-REQ-001..011, PRD-V3N-REQ-017..027, PRD-V3N-REQ-037 require no MHD and one route behavior across three versions. + +**Options considered:** (1) One protocol-neutral exchange above owned, separate wire engines: deep interface and local protocol changes, but significant implementation. (2) Three public request APIs: simpler engines, divergent handlers. (3) Keep a replaceable HTTP backend: smaller initial implementation, violates no-dependency and backend-free API goals. + +**Decision:** Option 1. Connection-owned HPACK/QPACK/QUIC state stays below semantic streams. + +**Rationale:** One semantic route contract meets cross-version behavior without exposing wire state; separate engines keep compression and transport rules local. + +**Consequences:** Protocol interop and security testing are release critical. Supersedes v2 MHD backend decisions and DR-014's MHD callback composition for v3. + +### DR-V3-002: OpenSSL 3.5 LTS is the sole optional TLS/crypto provider + +**Status:** Accepted. **Date:** 2026-09-28. + +**Context:** PRD-V3N-REQ-002..003, PRD-V3N-REQ-007, PRD-V3N-REQ-034..036 require dependency-minimal QUIC TLS, certificate policy, and ACME. + +**Options considered:** (1) OpenSSL 3.5 LTS: official third-party QUIC TLS callback API and one crypto project, with young API to test. (2) GnuTLS 3.8: low-level handshake hooks but more QUIC glue and mandatory Nettle/GMP dependencies. (3) Write TLS/crypto in-tree: unacceptably large security scope. + +**Decision:** Option 1. Exact patch floor follows current security advisories at implementation/release. + +**Rationale:** OpenSSL provides the required QUIC TLS callback interface and cryptographic primitives through one external provider. + +**Consequences:** A TLS-on build uses OpenSSL privately; v2 GnuTLS configuration migrates to provider-neutral options. TLS-off remains dependency-free. + +### DR-V3-003: Coroutine exchange plus bounded synchronous route adapter + +**Status:** Accepted. **Date:** 2026-09-28. + +**Context:** PRD-V3N-REQ-009, PRD-V3N-REQ-021..027, PRD-V3N-REQ-031 and the small-endpoint JTBD require both streaming control and concise routes. + +**Options considered:** (1) Coroutine exchange only: smallest surface, more ceremony for simple routes. (2) Canonical coroutine exchange plus named sync adapter: same engine, simpler common case, two documented route modes. (3) Lifecycle callbacks: no coroutine ABI but larger per-application state machines. (4) Value-returning handlers only: easy common case but suspension, duplex and backpressure require special cases. + +**Decision:** Option 2. The sync adapter has an explicit body cap and shares exchange lifecycle. + +**Rationale:** The exchange makes backpressure and cancellation explicit, while the adapter preserves a short path for bounded endpoints. + +**Consequences:** Public `task` scheduling, cancellation, lifetime, and exception rules become ABI contracts. Replaces v2's response-return/deferred handler model for v3. + +### DR-V3-004: Operation-oriented private I/O, readiness-shaped external integration + +**Status:** Accepted. **Date:** 2026-09-28. + +**Context:** PRD-V3N-REQ-014..016 and four OS families need external loop support while IOCP and Unix backends differ. + +**Options considered:** (1) Private operation boundary plus public readiness/timer adapter: portable, moderate surface; Windows external mode uses readiness. (2) Public completion-driver interface: native IOCP integration, substantially larger host contract. (3) Poll/WSAPoll for all modes: simple, less scalability headroom. + +**Decision:** Option 1. + +**Rationale:** One small external readiness contract works across the supported platforms without constraining the private native I/O backends. + +**Consequences:** Generation-tagged interests and dispatch semantics need cross-platform tests; internal managed mode can use IOCP without exposing it. + +### DR-V3-005: Immutable reusable response definitions, fresh per-send state + +**Status:** Accepted. **Date:** 2026-09-28. + +**Context:** PRD-V3N-REQ-026..030 require replayable concurrent reuse and explicit file/pipe/borrowed lifetimes. + +**Options considered:** (1) Immutable definition plus per-send cursor/source factory and overlays: safe reuse, more types. (2) Share a mutable response/cursor: small surface, races and ambiguous ownership. (3) Copy response per send: simple semantics, potentially expensive and cannot duplicate one-shot sources. + +**Decision:** Option 1. + +**Rationale:** Per-send cursors and owned overlays prevent concurrent sends from sharing mutable body or field state. + +**Consequences:** Non-replayable sources remain one-shot; borrowed resources need explicit lease. + +### DR-V3-006: Strict, connection-owned protocol state and hierarchical budgets + +**Status:** Accepted. **Date:** 2026-09-28. + +**Context:** PRD-V3N-REQ-004..008, PRD-V3N-REQ-021, PRD-V3N-REQ-027 and the bounded-memory acceptance gate. + +**Options considered:** (1) Per-connection serialized state with per-stream work, credit accounting, and limits: clear ownership but scheduler complexity. (2) Per-stream independent parsers/compressors: easy concurrency, invalid HPACK/QPACK and QUIC ownership. (3) One global protocol lock: simple correctness, cross-connection contention. + +**Decision:** Option 1. QUIC v1 with 0-RTT disabled is the v3.0 baseline. + +**Rationale:** Protocol compression and flow-control state belong to their connection, and 0-RTT adds replay policy without serving a v3 requirement. + +**Consequences:** State-machine, fairness, memory, and timer tests gate release. + +**Capacity clarification (2026-10-15):** PRD-V3N-REQ-014/016/037/039..043 use +independent typed H2/H3/QUIC profiles and one immutable resolved plan. The common +planner owns defaults, checked arithmetic, resource/wire bounds and owner +translation. Semantic `validate()` uses that planner without build availability; +pure `resolve_limits()` and native construction add the compiled-availability +gate before any bind. Credential publication stays in startup readiness. Cached +`effective_limits()` is independent of mutable credentials and runtime occupancy. +Native owners consume exact plan values in both loop modes. + +Compression directions share the existing aggregate budget: QPACK reserves its +decoder and peer-bounded encoder maxima, and HPACK includes the initial4096 +allowance until SETTINGS ACK. H3 planning uses production record/decoded/semantic +storage formulas, prepaid data/critical subdivisions and persistent native/flow/ +framing ledgers. It includes three local critical roles and three supported peer critical roles +(peer QPACK streams may be absent), scratch/receipt/output arrays, retained HEADERS, decoded metadata, semantic copies and transport/recovery/ +TLS workspace without charging prepaid storage twice. Explicit subdivisions may +grow within the root budget. One feasible request envelope is not a simultaneous +reservation promise for every advertised request. Terminal records retain a total +ledger bound while MAX_STREAMS replenishes on normal retirement. Header maxima +remain local and unadvertised; native datagram policy remains1200. Details and +public bounds are in `docs/v3-protocol-limits.md`. + +### DR-V3-007: Immutable TLS credential snapshots and exact ACME selection + +**Status:** Accepted. **Date:** 2026-09-28. + +**Context:** PRD-V3N-REQ-034..036 require live rotation and temporary ACME credentials. + +**Options considered:** (1) Validate and atomically publish immutable registry snapshots: established sessions safe, snapshot lifetime cost. (2) Mutate shared TLS contexts in place: smaller registry, unsafe concurrent behavior. (3) Restart listeners on change: simple, violates uninterrupted connections. + +**Decision:** Option 1; ACME only on matching TCP SNI plus `acme-tls/1`. + +**Rationale:** Snapshot publication preserves active handshakes and connections while exact SNI/ALPN selection isolates challenge credentials. + +**Consequences:** Validation and handshake concurrency tests gate release. + +### DR-V3-008: Split handler-safe stop initiation from drain completion + +**Status:** Accepted. **Date:** 2026-09-28. + +**Context:** PRD-V3N-REQ-031..033 directly reverse v2 DR-008's stop-in-handler deadlock contract. + +**Options considered:** (1) Nonblocking request plus separate deadline-bound ticket: safe in handlers, explicit coordination. (2) Blocking stop everywhere: self-deadlock. (3) Immediate close: loses active work and graceful protocol behavior. + +**Decision:** Option 1. + +**Rationale:** A handler can request shutdown without waiting for its own completion, while an external coordinator can observe the deadline outcome. + +**Consequences:** v3 supersedes DR-008's `stop()` exception; staged GOAWAY and WebSocket close need test coverage. + +## 7.

Native engines update fixed atomic +counters and enqueue scalar-only events into 128 fixed slots using `try_lock`. +Contention/full queues increment dropped-event accounting; cumulative event +counts saturate and survive delivery loss. No logging runtime or background +thread is added. Hierarchical budget accounting updates aggregate seat and +charged response-storage gauges after committed admission and release. +Refusals are recorded after rollback, once per charge chain. + +Applications explicitly dispatch on their own thread. Dispatch releases the +queue mutex before callbacks, rejects concurrent/reentrant dispatch, contains +callback exceptions, and bounds a call by its entry queue size. Producers never +run callbacks under an I/O or drain lock. Shared ownership keeps producers and +in-progress dispatch alive; destruction does not dispatch. Retained channels +can observe shutdown records after server destruction. Records have no freeform +text, request payloads, network identities or TLS credentials/metadata. +Protocol engines report lifecycle terminals once and flow-control stalls on +blocked transitions. Shared drain scopes arbitrate completion versus expiry +under their existing lock; event delivery remains explicit and independent. +See `docs/task-181-diagnostics.md` for counter semantics and application usage. + + +### Public native certificate TLS (TASK-193; DR-V3-004/006/007/008) + +`server::tls_credentials` is a shared opaque value handle over the existing +immutable credential registry. Listeners retain explicit stores, accepted +sessions acquire one complete generation, and replacement builds off-path then +publishes atomically. No provider, private snapshot or runtime handle enters the +installed API. Public certificate-only H1 credentials are available in TLS-on; +TLS-off keeps the same declarations and typed unavailability. TASK-194 through +TASK-197 subsequently provide public mTLS/PSK/ACME and H2/H3 integration; +TASK-199 records their current packaged execution boundary. + +Native listeners bind transactionally before activating accepts. One existing +connection engine reserves admission before TLS allocation, counts its handshake +in the drain scope and uses its existing serialized I/O owner for the explicit +handshake followed by H1 tasks. Certificate provider steps use the existing +bounded private runtime. TLS socket views retain immutable selection and genuine +peer metadata through session/child completion retirement; hooks and routes run +outside listener/I/O locks. Both loop modes advance the same network and deadline +operations. See [the design comparison](TASK-193-design.md) and implementation +evidence for disproving tests and installed-package identities. + +### TASK-195 public TCP HTTP/2 integration + +Native certificate and initial mTLS listeners now select enabled `h2` through +ALPN and compose the existing HTTP/2 protocol engine under the accepted TCP +connection lifecycle. A serialized wire owner and independent stream affinities +separate protocol state from application coroutine state. PSK stays HTTP/1-only; +TASK-196/197 provide public H3; TASK-199 composes the current installed evidence. Ownership, bounded semantic handoff, +resource hierarchy and native timer/drain details are in +[TASK-195-design.md](TASK-195-design.md); local verification is recorded in +[TASK-195-implementation-evidence.md](TASK-195-implementation-evidence.md). + +### TASK-196 native UDP / basic HTTP/3 + +Explicit transport entries preserve TCP defaults and configuration-index actual ports. The native pimpl transactionally composes `quic_udp_listener`, per-connection `quic_network_connection` and independent native H3 stream affinities with owned bounded handoff. TLS compatibility now includes enabled H3 and transport applicability while PSK stays HTTP/1-only. Coordinated stop preserves backend/workers/services through real QUIC close expiry; an exclusive private external retirement drive replaces host dispatch only after quiescence. See [TASK-196-design.md](TASK-196-design.md) for alternatives, resource bounds and deferred TASK-197 scope. + +### TASK-199 packaged release execution adapters + +Public consumers are copied out of the archive extraction and compile only +against identified installed C++20 headers/libraries. The public family composes +H1/RFC6455, credentials/profiles, H2 and H3; private suites cannot supply its +proof. The benchmark family retains raw samples and the existing epoch/statistics +contracts. Source archives require no Git checkout. Artifact catalogs include +child receipts, commands, processes, depfiles, link maps, executables, fixtures +and selected client/tool inputs. Both adapters use exclusive outputs and +caller-bound run IDs, preserving failed attempts. No general stage registry or +TASK-185 runner import is introduced. Its exact integration remains TASK-185 owned. + +### Source ownership and compiled operations + +Public non-template implementation is compiled in `src/.cpp`, paired +with installed `src/httpserver/.hpp`. Private implementation is compiled +in `src/detail/.cpp`, paired with noninstalled +`src/httpserver/detail/.hpp`. Cohesive engine splits explicitly share +their actual owning header; matching basenames do not require dummy headers or +recombined protocol engines. Provider-conditioned implementation stays within +the private provider target. + +Templates and constexpr operations remain visible for instantiation and constant +evaluation. Trivial accessors, value operations and small byte/arithmetic +primitives may remain inline with the recorded reason in +[the complete ownership inventory](../../../docs/v3-source-layout.md). Complete +public representation and template support remain in installed headers, including +necessary detail declarations. An installed header never includes a noninstalled +private header. Normal library linkage supplies compiled operations; standalone +header compilation does not imply link-free runtime behavior. Extraction preserves +API, representation, suspension points, resource accounting and protocol behavior. + +### Selected-archive CI release acceptance + +CI keeps the existing TASK-185 18-gate validator authoritative. One selected +archive and source/tooling snapshot feed native/installed platform producers, +then the Linux full inventory. Linux evidence remains on its original +filesystem; only fixed FreeBSD/Darwin/Windows receipts cross the platform seam. +A bounded namespaced logical-path catalog preserves original receipt bytes and +retains every referenced package input. Import reruns origin validators and +normalizes foreign paths only for lookup/comparison, never binary execution. + +The final job consumes content-bound authorization, same-run immutable artifact +IDs/digests and the exact archive. It rechecks manifest/source/tag bindings and +executes no downloaded candidate code. Only that job receives publication +permission. PR/validation-only execution cannot publish. This design accepts a +serial release critical path to avoid moving the complete Linux evidence tree +or broadening existing protocol validators.

It selects the fixed `ICY` token for this final +HTTP/1 response only; all framing, HEAD/no-content rules and keepalive +stay ordinary. Status numeric equality/categories ignore the marker, +and `100 Continue` stays `HTTP/1.1`. Construct an ordinary `from_code` +value for the next response. No audio metadata is added. + +`response_definition::reopen_file(status, fields, path, definition)` +replaces `http_response::file(path)` and opens a fresh file per send. +The application can preserve v2's sanitized missing-file page by +checking `send_definition`'s report before committing a response: + +```cpp +const auto report = co_await send_definition(exchange, definition, {}); +if (!report.status.ok() && exchange.state() != exchange_state::responded) { + // Return a sync value with status 500, Content-Type text/plain, + // and body "Internal Server Error" through the normal value adapter. + // Do not expose report.status.message() in the response body. +} +``` + +A post-commit failure remains a typed stream failure; it cannot replace +the response. The general send API does not synthesize a file-specific +500 body. The executable adapter is `test/integ/native_http1_parity_test.cpp`. + +`owned_pipe` takes a transferred `FILE*` (for a descriptor, wrap using +`fdopen`) and closes it exactly once; it is one-shot. Deferred callbacks +map to `factory`: return one fresh `body_producer` per send, whose pulls +return `body_chunk{outcome, span, end}`. The spans must remain alive +until the next pull. For scatter/gather, a factory pulls the original +borrowed spans in sequence under their owner lifetime; declare the +known Content-Length. There is no direct native iovec factory. For one +contiguous borrowed buffer, use `borrowed(..., body_lease(owner), ...)`; +the lease pins the immutable storage across concurrent sends. + +Request raw query bytes remain in `exchange.head().raw_target`; split +at `?` for the v2 `get_querystring` equivalent. Query decoding is an +application opt-in with explicit limits (`forms::decode_urlencoded`). +Form and path arguments have separate adapters/surfaces rather than the +v2 merged arg map. Cookie helpers remain standalone: parse the Cookie +field with `cookie::parse_cookie_header`, render each response cookie +with `cookie::to_set_cookie_header`, and append one Set-Cookie field +per rendered value. Request trailers are `exchange.body().trailers()` +once the reader reaches end-of-body. + +The inventory records the existing routing/hook/IP migration exceptions. +TLS and WebSocket are deferred to their owning tasks; TASK-120 does not +claim native coverage for those protocols. + +## Native HTTP/1.1 WebSocket upgrade (TASK-122) + +Register a normal coroutine route. `co_await exchange.upgrade(options)` +returns an owned `websocket_upgrade_result`; on success its move-only +`session` owns the application's protocol state and +`selected_subprotocol` names the server-preferred offered token. Success +means the trusted 101 head entered bounded output. It does not promise +TCP delivery. The transport writes the entire ordered HTTP outbox before +any frame. No extension is negotiated, including permessage-deflate. +This native path does not depend on the legacy `HAVE_WEBSOCKET` flag. + +```cpp +task native_echo(exchange& x) { + ws_upgrade_options options; + options.subprotocols = {"chat"}; + options.allowed_origins = {"https://example.com"}; + options.allow_absent_origin = false; + auto upgraded = co_await x.upgrade(std::move(options)); + if (!upgraded.status.ok()) { + upgraded.rejection_fields.append("Content-Length", "0"); + x.respond(upgraded.rejection_status, upgraded.rejection_fields); + co_return; + } + auto session = std::move(*upgraded.session); + resume_signal closed; + session.on_close([closed](websocket::close_info) mutable { + closed.signal(); + }); + for (;;) { + auto received = co_await session.receive(); + if (!received.value) break; + for (;;) { + auto sent = session.try_send(received.value->kind, + received.value->data); + if (sent.disposition == websocket::send_disposition::accepted) + break; + if (sent.disposition != websocket::send_disposition::backpressured) + co_return; + if (!(co_await session.writable()).ok()) co_return; + } + } + co_await closed.wait_for(std::chrono::seconds(5)); +} +``` + +Refusal is nonterminal and leaves the exchange available for an ordinary +response: malformed handshake 400; denied origin 403; otherwise-valid +unsupported version 426 with `Sec-WebSocket-Version: 13`. Invalid API +state and invalid configured limits remain typed failures. Upgrade is +legal only before body admission or any other terminal decision. +Callers must await the lazy task while the exchange is alive; options +are copied or moved into that task before its first execution. + +Default origin policy permits an absent Origin and any syntactically +valid serialized origin. A nonempty allowlist matches the complete +serialized value exactly. Accepted values are `null`, or lower-case +`http://` / `https://` plus an ASCII letter/digit/hyphen/dot hostname or +bracketed IPv6 literal and an optional decimal port 1–65535. Paths, +credentials, lists and repeated Origin fields are refused. Case and +default ports are not normalized: `https://example.com:443` differs +from `https://example.com`. Origin policy is not authentication. +Subprotocols are case-sensitive tokens selected in server preference +order; no match normally omits the response field. Set +`require_subprotocol` to refuse no-match. Policies and offer lists each +have a 256-entry bound in addition to head byte/field budgets. Session +limits project down to connection budgets and may be tightened per route. + +Destroying the session cancels it. An application initiating a clean +Close must register an `on_close` signal first, call `session.close()`, +and retain the session while awaiting that signal with its own deadline. +Returning immediately after `close()` can cancel unsent output. The +transport's private progress observer is independent of this callback. +Abrupt server stop safely cancels pending receive/writable work. +`begin_drain(budget, ticket)` stops admission and starts WebSocket Close +with code 1001 and reason `server drain`. Keep the session through its +`on_close` notification, including when `receive()` reports peer Close. +Drain initiation is nonblocking inside a handler; waiting there returns +`would_deadlock`. An external ticket wait reports completion after all +engine and handler units leave. A ticket may outlive its server. + +The first successful application, peer or drain Close fixes an immutable +steady-clock anchor. The effective deadline is the earlier of that anchor +plus `timeouts.ws_close` and the server's absolute drain deadline. Writes, +traffic, notifications and 101 promotion do not extend it.

Migration exceptions: `connection_opened`/`connection_closed` are MHD-notify artifacts and remain unported — the documented v3 per-connection observation seats are accept_decision (admission), request_completed (settle), and `exchange::peer()`; `body_chunk` is not ported — v3's pull-based body model puts pre-body control at `request_received` and per-chunk visibility in the handler's read loop (firing user code in the engine reader loop would violate the threading contract). | +| `http_resource::add_hook` attaches per-route hooks; server-wide hooks fire before per-route hooks, registration order within a scope | src/httpserver/webserver_hooks.hpp (http_resource::add_hook); docs/architecture/hooks.md | — | inventory-only | TASK-118: per-resource attachment is NOT ported — per-route composition is a wrapping `route_handler` (the adapter idiom: the wrapper runs its pre/post logic around the inner handler, which also covers per-route phase selectivity and ordering); server-wide hooks live on the `server::hooks()` bus alone. | +| The alias setters `internal_error_handler`, `auth_handler` and `log_access` install bus-backed handlers | README.md §Error propagation; src/httpserver/webserver_hooks.hpp alias callouts | — | inventory-only | TASK-118: no v3 aliases — the `handler_exception` chain covers the 500 path (v2 answered a throwing `internal_error_handler` with the hardcoded empty-body 500 via `run_internal_error_handler_safely`; v3 preserves that containment -- a throwing hook on the chain is treated as `pass()` and the bare empty-body 500 answers -- and a double-fault is likewise the hardcoded empty-body 500), auth guards own their failure mode (no engine-wide seat), and access logging maps to the `response_sent`/`request_completed` phases; a throwing hook is caught, treated as `pass()`, and a pre-commit phase's contained throw (request_received/route_resolved/before_handler) is surfaced through the `handler_exception` chain at the dispatcher (a commit-path phase's throw cannot replace the committed head; the chain fires at most once per request). | + +## Basic authentication + +| Documented v2 behavior | Documentation source | Transcript case | Baseline status | Migration note | +|---|---|---|---|---| +| Missing credentials answer 401 with `WWW-Authenticate: Basic realm=""`, empty body | README.md §Authentication; src/httpserver/create_webserver.hpp; src/httpserver/http_response.hpp `unauthorized(scheme, realm)` | auth_basic.tseq:no_credentials | pinned | | +| Valid Basic credentials admit the request (200) | README.md §Authentication; src/httpserver/create_webserver.hpp | auth_basic.tseq:valid_credentials | pinned | | +| Invalid credentials re-challenge 401 with the same header shape | README.md §Authentication; src/httpserver/create_webserver.hpp | auth_basic.tseq:invalid_credentials | pinned | | + +## Digest authentication + +| Documented v2 behavior | Documentation source | Transcript case | Baseline status | Migration note | +|---|---|---|---|---| +| Unauthenticated request answers 401 with an RFC 7616 §3.3 challenge: `realm`, `qop="auth"`, `algorithm=MD5`, server-generated `nonce`/`opaque` (volatile, `<*>`-masked), `charset=UTF-8` | docs/architecture/errors.md (Digest challenge format); TASK-062 digest_challenge contract | auth_digest.tseq:challenge_structure | pinned | | +| Full RFC 7616 round-trip against the server nonce admits the request (200) | README.md §Authentication; src/httpserver/http_request.hpp; docs/architecture/errors.md | auth_digest.tseq:roundtrip_digest (curl-mediated) | pinned | | + +## Forms and multipart uploads + +| Documented v2 behavior | Documentation source | Transcript case | Baseline status | Migration note | +|---|---|---|---|---| +| `application/x-www-form-urlencoded` POST fields are parsed and visible to the resource | README.md §Request / Headers, arguments, cookies; src/httpserver/http_request.hpp; docs/architecture/features.md | forms.tseq:urlencoded_echo | pinned | TASK-116: the v3 surface is the per-route `forms::make_urlencoded_route` adapter (the `httpserver::forms` area, decode within cap identical to v2: first-`=` split, `+` as 0x20, strict `%HH`, arrival-order repeats, first-value lookup).

Migration deltas: (1) caller-provided part sinks replace the library-side in-memory file copy (v2 concatenated every upload into the flat arg map via `set_arg_flat` -- an unbounded-copy antipattern not ported; `temp_file_part_sink` ports the disk-upload behavior: random or sanitized basenames under a directory, pre-truncation of leftovers, partial-file removal); (2) the four `multipart_limits` budgets (raw bytes, parts, per-part bytes, header block; defaults 65536/64/65536/8192 mirroring v2's arg budgets) answer 413 BEFORE any unbounded storage where v2's effective default was unbounded (`content_size_limit = SIZE_MAX`); (3) strictness deltas answer 400 where MHD silently produced no parts: missing first/final boundary, a delimiter truncated at EOF, a header line without a colon or CRLF, a part without a usable Content-Disposition (no `name`), a boundary outside RFC 2046 bchars or longer than 256 chars; (4) the documented hooks are the sink callbacks themselves -- `on_part_abort` fires exactly once per begun-but-unended part on every non-ok terminal (disconnect, cancellation, rejection, sink failure) and `should_keep` is consulted exactly once per completed file at sink destruction (false/null/throwing removes, v2 `file_cleanup_callback` rules); the server-wide `request_completed`-on-abort wiring landed in TASK-118 (the v3 lifecycle bus fires the phase exactly once per exchange settle, disconnect included). | +| MHD's post processor tolerates LWSP transport padding of any length after a multipart delimiter while scanning for the terminating CRLF | RFC 2046 §5.1.1 (delimiter transport padding); TASK-117 streaming invariant (`forms/multipart.hpp`: the raw body is never buffered whole) | forms.tseq:multipart_field | pinned | TASK-117 validation: v3 bounds the tolerated delimiter padding to the boundary length plus 8 bytes; a longer run (terminated or not) is the typed `invalid_argument` 400 strictness delta recorded in the TASK-117 decoder matrix (at-bound padding decodes, one byte past is the sticky rejection, and an unterminated run over many 512-byte feeds is rejected during a feed).

No forced application exit, DLL pinning or public shutdown interface is introduced. + +## Focused proof and context limits + +A C-only consumer of the retained actual CI DLL reaches its default timer factory and prints `DEFAULT_TIMER_READY`, then fails to exit within 9 seconds; its retained handle is retired, with total 9.449 seconds. No C++ standard-library object crosses that ABI boundary. This is a new minimal regression, not another original native62 launch. + +The new registered C++ regression runs a matching small three-owner DLL (`resume_signal.cpp`, `task.cpp`, `executor.cpp`) with explicit retirement and default-exit children. The final test against original timer source is RED: exit 1, child wait timeout 258 and destruction-during-shutdown marker, total 9.372 seconds. Against fixed source it is GREEN: exit 0, total 0.491 seconds, no shutdown destruction marker. Each child has a 9-second wait and at most 1 second for owned retirement. An inherited event observes pending-capture destruction during actual process termination, so the assertion also protects runtimes whose condition variable does not itself hang. Static-executable normal CRT destruction is permitted by this test and passes separately. Ordinary explicit retirement joins the worker and releases a capture with an hour-long pending deadline. + +Linux focused tests pass: `task_timer_shutdown`; `task_resume_signal` 11 tests/134 checks; `task_resume_signal_lifetime` 3 tests/1816 checks. These use current source compiled with GNU13/C++20/pthreads and only the three owning concurrency translation units. Changed-file cpplint and `git diff --check` pass. `autoreconf -fi` registers the new program and inherited library linkage; existing AC_OUTPUT and .PHONY warnings are recorded without unrelated repair. No full baseline or broad suite was run. + +Native Windows context is Windows 11 build26200, cross LLVM-MinGW23.1.4/MinGW15 with its UCRT startup/headers, MSYS2 GCC15.2 standard-library headers/import libraries in an owned cache, and the retained actual CI MSVCRT libstdc++/libgcc/winpthread DLLs. Actual CI uses Windows Server2022 and LLVM23.1.0 with MSYS2 mingw64 throughout. This focused mixed-CRT proof is qualified; it does not replace full actual CI. No provider, SDK or compiler was built or globally installed. A first downloaded UCRT GCC package was unused after original imports identified MSVCRT. + +Preserved setup failures: sandboxed WSL native launch was unavailable before normal escalation; initial future-based fixture had unresolved libstdc++ TLS symbols, then a corrected TLS build exposed missing runtime once-call exports (native entry-point status C0000139). That setup failure is not RED. Replacing only test readiness synchronization with an already-supported Win32 event corrected the fixture boundary; the corrected native failure above is the behavioral RED. No production workaround was based on the setup error. Raw commands, logs, receipts, hashes and bounded ownership cleanup are retained in stage evidence. + +Darwin PSK failures, Windows host WSAPoll consumer failure and incidental Linux/macOS/BSD assessments retain their previous UNKNOWN/closed-budget states.

It supplies useful error evidence in the next already-required CI run; it does not diagnose or repair the prior consumer exit 6, whose cause remains UNKNOWN and captures remain closed. There are no per-poll traces, socket queries, clocks, locks or error suppression changes. + +A bounded Windows test substitutes only the external WSAPoll boundary to return WSAEINVAL through the actual Winsock last-error API. Before the change it returns 2 because the exception omits numeric 10022 (0.310s); after it exits 0 (0.303s), also checking that WSAEINTR still produces no exception. This controlled message regression is not a reproduction of the original consumer failure. Actual Windows compilation, GNU syntax checking of `examples/external_event_loop.cpp`, changed-header cpplint and diff checks pass. Commands, sources and receipts are under stage evidence `host-poll-message/`. + +Additional ordinary cleanup proof: a static-linked Windows default service releases its pending callback during normal executable CRT teardown before a later registered atexit observer checks the capture; exit 0 in 0.391s (`ordinary-default-native-test.json`).

This is retained raw-log/metadata evidence; the artifact was not downloaded for stage3.

Initial synchronization and guest execution are distinct earlier operations. The input is declared in the [pinned action metadata](https://raw.githubusercontent.com/vmactions/freebsd-vm/c9f815bc7aa0d34c9fdd0619b034a32d6ca7b57e/action.yml). Disabling only this redundant post-run copyback leaves the explicit required SCP transport responsible for retrieving evidence.

Its real compiler check was + `clang -std=gnu23 -lws2_32 -lmswsock -lbcrypt -lpthread -no-undefined conftest.c`; + clang reported `unknown argument '-no-undefined'`. Zero staging cases ran. + The terminal failed-job log is `/tmp/v3-ci-win-diag-run40017021624-log-failed.txt`. +- Verified cause: the installed-package driver supplies `LDFLAGS` in the outer + make environment, including when empty. GNU make replaces that inherited value + with its configured assignment and exports it to the Python fixture. The fresh + nested configure consequently receives the libtool-only option as compiler + LDFLAGS. This is established by actual configure/make/clang RED/GREEN, rather + than a compiler simulation or a guessed flag workaround. +- `configure.ac` now keeps only `-lpthread` in the MinGW, MSYS and Cygwin + additional-library assignments. Windows socket/bcrypt flags and pthread + linkage remain. The existing aggregate `libhttpserver_la_LDFLAGS` still owns + `-no-undefined`; a real configured libtool-link dry run confirms it remains. +- The task-local `implementation/configured-flags-probe.py` executes real outer + configure with the Cygwin host arm on Linux, using `CC='clang -std=gnu23'`, + `CXX=clang++` and `LDFLAGS=''`, then invokes production + `make check-v3-stage-install`. RED exports `-lpthread -no-undefined` and fails + at the identical real clang diagnostic before any test runs. GREEN exports + only `-lpthread`; the unchanged actual eight-case fixture passes in 20.460s. + This tests flag inheritance locally; it is not a native Cygwin/Windows runtime + result. Inputs/source hashes, outer configure logs, exported flag snapshots, + fixture output and the libtool-link dry run are retained beside the probe. +- The temporary workflow is restored byte-for-byte to base `6fc67232`. + Bootstrap passes with the existing warnings. All 4 package workflow tests, + actionlint 1.7.7 (optional shellcheck unavailable), all 18 shell-body syntax + checks, Python syntax and diff whitespace pass.

The v2.0 cutover is single-shot (no Alpha→Beta→GA phasing per PRD §1), so milestones are technical layers that each leave the public API in a compilable state and exercise an outcome a downstream consumer would care about. There is no parallel maintenance branch — v1.x is end-of-life on the day v2.0 ships (DR-011, OQ-007). @@ -143,6 +248,111 @@ Nominally: **13 sequential tasks**, each S–XL.

The only record of the deferral is the scope comment in src/httpserver/auth/digest_auth.hpp:30-36, whose rationale ('the two non-session algorithms the v2 surface exposed') is itself inaccurate about the v2 baseline, which exposed three. PRD-V3N-REQ-038 (specs/product_specs.md:390) requires that a documented v2.0 capability exercised through its v3.0 equivalent 'preserve its externally observable behavior unless a v3.0 migration note explicitly records the change', and architecture release gate 5 (specs/architecture/v3/architecture.md:141) requires 'Every intentional behavior change receives a migration note'. The designated home is the Migration note column of the Digest table in specs/architecture/v3/v2-parity-inventory.md, whose valid documentation sources explicitly include 'the v2 public-header contract in src/httpserver/'; both existing Digest rows (lines 79-80) have empty migration-note cells and there is no row covering algorithm selection, userhash, or domain, so the TASK-128 parity gate has nothing to remind it of these drops.

The v3 architecture documents exactly this contract for the analogous psk_lookup callback ('applications must make their lookup safe for that concurrency', section 4).

[ ] **code-quality-reviewer** | `test/unit/digest_auth_policy_test.cpp:71` | test-coverage + The public options.max_nc knob (digest_auth.hpp line 126) has no policy-level coverage: ledger exhaustion is unit-tested in digest_nonce_ledger_test.cpp (nc_admission_matrix, lines 257-264) and the exhausted->stale_nonce mapping exists in gate_nonce (src/detail/auth_digest.cpp lines 171-173), but no test constructs a policy with max_nc set and asserts the end-to-end 401 + stale=TRUE + fresh nonce behavior on the nc-after-cap request. Every other public option (ttl, ledger_capacity, opaque, challenge_body, algorithm) has a policy-level test. + *Recommendation:* Add a policy test with options.max_nc = 1: first round authenticates; a second request with a strictly larger nc on the same nonce answers stale_nonce with ', stale=TRUE' and a fresh nonce (mirrors the ttl=0 test's shape). + +10. [ ] **code-simplifier** | `src/detail/auth_digest.cpp:159` | code-structure + The nonce timestamp is decoded twice: classify_nonce already decodes all 56 bytes and computes 'stamped' internally (digest_nonce.hpp lines 164-176) but discards it, then gate_nonce re-decodes params.nonce.substr(0, 16) and re-loads BE64 to compute the expiry. The second decode also re-encodes the layout knowledge as magic numbers (16 here, k_nonce_hex_length - 64 in classify_nonce) with no named head-length constant tying them together. + *Recommendation:* Have classify_nonce expose the decoded timestamp (out parameter or a small result struct carrying class + stamped) so gate_nonce consumes it directly, and name the head/tag split (k_head_hex_length = 48, k_tag_hex_length = 64) in one place. Behavior-preserving; also removes an allocation per check. + +11. [ ] **code-simplifier** | `src/detail/auth_digest.cpp:266` | consistency + Two idioms express the same 'retry the entropy draw exactly once' semantic inside one change: mint_nonce and mint_key use an explicit 'for (attempt < 2)' loop (digest_nonce.hpp lines 146 and 196), while make_state's opaque draw uses the short-circuit conjunction 'if (!fill(draw).ok() && !fill(draw).ok())'. The double-call form is correct (short-circuit) but reads like an accidentally duplicated call and is the kind of line a future reviewer will 'fix' wrongly. + *Recommendation:* Use one idiom for all three draws -- either the explicit two-iteration loop (matching digest_nonce.hpp, where the retry-once contract is unit-pinned) or a tiny 'fill_with_retry(span)' helper in entropy_sys.hpp that all three call. + +12. [ ] **code-simplifier** | `src/detail/auth_digest.cpp:457` | code-structure + verify()'s nonce-gating initializer mixes two control flows in one expression: a ternary that either constructs an engaged std::optional for the unconfigured policy or calls gate_nonce. The surrounding pipeline uses flat early returns (malformed at 446, gated at 463, material at 467), so this one branch forces the reader to unpack optional-construction semantics to see that the unconfigured policy simply refuses. + *Recommendation:* Hoist the unconfigured case into a guard clause before the gating: 'if (state_ == nullptr) { settle(verdict, digest_auth_result::credentials_rejected); return verdict; }' and let gate_nonce's result flow through the existing optional path unchanged. + +13. [ ] **code-simplifier** | `src/detail/auth_digest.cpp:97` | duplication + append_escaped() (find_first_of("\\\"") fast path, then backslash-prefix escaping) is a line-for-line duplicate of the quoted-string escaping inlined in auth_basic.cpp build_challenge (lines 144-151). This task created detail/auth_text.hpp precisely as the shared basic/digest text boundary and moved the case helpers there; the escaper is the obvious second resident and leaving it duplicated re-adds the very duplication the extraction was made to remove. + *Recommendation:* Move the escaper into detail/auth_text.hpp (e.g. auth_text::append_escaped(std::string&, std::string_view)) and use it from both build_challenge implementations. Purely mechanical, byte-identical output. + +14. [ ] **code-simplifier** | `test/unit/digest_auth_policy_test.cpp:308` | consistency + expired_nonce_is_stale computes the response with one make_cnonce() draw (line 309) but ships a different draw inside build_authorization_header (line 311), directly contradicting the file's own answered_authorization comment at lines 104-106 ('two draws would sign one value and send another'). The pinned verdict does not depend on the response (nonce expiry is classified before response verification), so the test passes, but the code presents itself as a valid client round while sending an internally inconsistent Authorization -- misleading to maintainers and one refactor away from silently testing nothing about the answer path. + *Recommendation:* Hoist one 'const std::string cnonce = dclient::make_cnonce();' and pass it to both compute_response_cleartext and build_authorization_header, exactly as answered_authorization and the e2e answered_digest helper (native_http1_e2e_test.cpp) already do. + +15. [ ] **performance-reviewer** | `src/detail/auth_digest.cpp:158` | memory-allocation + gate_nonce re-decodes the nonce timestamp via decode_hex(params.nonce.substr(0, 16)) immediately after classify_nonce already decoded the full 112-hex nonce into a 56-byte vector (src/httpserver/detail/digest_nonce.hpp:164) — a second heap vector and a redundant decode of the same bytes on every authenticated request. + *Recommendation:* Have classify_nonce return the stamped seconds (out-param or small result struct), or decode the 16 hex chars into a fixed std::array at the gate_nonce call site, so the nonce is decoded once per check (plan: 'check() allocation-light where practical'). + +16. [ ] **performance-reviewer** | `src/detail/auth_digest.cpp:432` | memory-allocation + check() copies state_->challenge_body into the verdict before classification, so every authenticated request also copies the configured challenge body (the factory caps its content but not its size) even though the body is consumed only by non-authenticated verdicts. + *Recommendation:* Copy the body lazily in settle() only when the verdict is non-authenticated; the authenticated early-return (auth_digest.cpp:477-480) then performs no body copy. + +17. [ ] **performance-reviewer** | `src/httpserver/detail/digest_nonce.hpp:123` | missing-caching + nonce_tag_hex rebuilds encode_hex(key) (a 64-char allocation plus 64 byte encodings) and the ~186-byte mac string on every classify_nonce call, but the MAC key is fixed per policy — a derived value of a constant input is recomputed per request on the auth hot path. + *Recommendation:* Precompute the key hex (or the constant 'libhttpserver-v3-nonce-v1|…|' suffix) once in digest_auth_policy::state and pass it to mint/classify; the SHA-256 tag itself stays per-check by design. + +18. [ ] **performance-reviewer** | `src/httpserver/detail/digest_params.hpp:287` | memory-allocation + The parse loop constructs fresh std::string name/param_value per auth-param (up to 24 iterations). Typical Digest values (nonce 112 hex, uri, cnonce, response 32/64 hex) exceed SSO, so a normal ~9-param Authorization header pays ~9 avoidable heap alloc/free pairs per request; parse_quoted also grows the value push_back-by-push_back with no reserve. + *Recommendation:* Hoist name/param_value above the loop and clear() them each iteration so capacity is reused (assign/append keep the buffer), and reserve a small floor (e.g. 64 bytes) before the quoted-value loop. + +19. [ ] **security-reviewer** | `src/detail/auth_digest.cpp:206` | error-handling + The declared invariant 'check() never throws, no exceptions escape' (CWE-248) is implemented only by convention. resolve_ha1() invokes the application-supplied digest_ha1_source callback (line 206, reached from verify() at line 473) with no exception barrier: a throwing application callback propagates out of check() and out of the make_digest_guard coroutine into the server's request machinery. Bounded allocations inside check() (parser caps keep strings at 8 KiB, plus challenge minting) are the only library-side throw sources and are remote bad_alloc paths. The fixed-credential form (no callback) has no realistic throw source. + *Recommendation:* Wrap the callback invocation (or the whole verify() pipeline) in a try/catch that maps any exception to credentials_rejected (or nonce_unavailable for minting failures), and/or document the nothrow requirement on digest_ha1_source in the public header so the 'no exceptions escape' contract is enforced rather than assumed. + +20. [ ] **security-reviewer** | `src/httpserver/detail/digest_nonce.hpp:82` | spec-conformance + The frozen validation baseline declares 'nonce = 96 lowercase hex (t‖r‖tag)' but the implementation mints and classifies 112 lowercase hex characters (56 bytes: t=8 bytes/16 hex, r=16 bytes/32 hex, tag=32 bytes/64 hex; k_nonce_hex_length = 112). The implementation plan's own section 3 heading ('96 hex = 48 bytes') contradicts its byte layout (8+16+32 = 56 bytes); the code follows the byte layout. Security impact is neutral-to-positive (16 bytes of entropy and a 32-byte tag are at least as strong as any 96-hex reading, and nothing pins the nonce length on the wire: no v2 corpus pin or client interoperability depends on 96 hex). The deviation is purely against the frozen baseline text and must be reconciled so later closure reviews do not misread it as drift. + *Recommendation:* Amend the frozen baseline/plan text (and, if desired, the TASK-115 migration notes) to state the actual 112-hex nonce layout, or shrink r to 8 bytes if the 96-hex form is contractual. No code change required for security. + +21. [ ] **security-reviewer** | `test/unit/digest_auth_policy_test.cpp:229` | test-coverage + The frozen invariant 'slot advances before password verification (a failed guess burns its nc)' is correctly implemented (gate_nonce admits into the ledger before resolve_ha1/response_accepts run in digest_auth_policy::verify) but no test asserts its observable consequence: after a failed password attempt at (nonce, nc), a CORRECT retry presenting the same (nonce, nc) must classify as replayed_nonce. The wrong_material_is_rejected test (line 229) checks only the immediate credentials_rejected result; the ledger test exercises nc monotonicity but not the verify-ordering effect, and the plan's test design item 1 explicitly names this case ('last_nc advances even when verification later fails'). + *Recommendation:* Add a policy-level sequencing test: obtain one challenge, present a wrong-password answer at nc=00000001 (expect credentials_rejected), then present the correct-password answer at the same nc=00000001 (expect replayed_nonce, no stale), and finally at nc=00000002 (expect authenticated). + +22. [ ] **spec-alignment-checker** | `scripts/check-duplication.sh:null` | specification-gap + The repo-wide duplication gate (scripts/check-duplication.sh, wired into .github/workflows/verify-build.yml:889) is red at CPD_MIN_TOKENS=100 on duplications entirely inside files untouched by this branch: src/httpserver/body_reader.hpp:157 vs src/httpserver/response_writer.hpp:162 (144 tokens) and src/httpserver/concurrency/task.hpp:532 vs :615 (133 tokens), all last modified by TASK-111/104/098 before base 45ecb8aa. TASK-115's task-scoped gates are green (build, focused suites, e2e, corpus, A1/A2 linkage audit, hygiene sentinels), but the baseline's blanket 'gates green' claim holds only task-scoped; this failure is not attributable to the TASK-115 diff. + *Recommendation:* Route to the milestone task owning body_reader/response_writer/task.hpp duplication; no TASK-115 action. Noted here so closure review does not mistake it for a regression of this task. + +23. [ ] **spec-alignment-checker** | `specs/architecture/v3/v2-parity-inventory.md:null` | specification-gap + PRD-V3N-REQ-038's migration-note mechanism was not exercised for TASK-115's intentional Digest deltas. v2's documented surface offered digest_algorithm::SHA512_256 in check_digest_auth (src/httpserver/http_utils.hpp:148) with that parameter defaulting to SHA256 (src/httpserver/http_request.hpp:310), and the v2 digest_challenge (TASK-062) carried domain/userhash/prefer_utf8 knobs. v3 intentionally offers only MD5/SHA-256 non-sess, defaults MD5, and omits the knobs; this deferral is documented only in the src/httpserver/auth/digest_auth.hpp header comment (lines 30-36) and the plan (which says 'migration note' for these rows), while the parity inventory's Digest section has no migration-note entries (the convention TASK-105/107 established for intentional changes). + *Recommendation:* Add migration-note entries to the Digest section of specs/architecture/v3/v2-parity-inventory.md (or seed the future v2-to-v3 migration guide) recording: SHA-512-256 verification dropped, check-API default changed from SHA-256 to MD5 (challenge default preserved as MD5 per the pinned transcript), and the domain/userhash/prefer_utf8 challenge knobs absent from the v3 surface. + +24. [ ] **spec-alignment-checker** | `src/httpserver/auth/digest_auth.hpp:218` | specification-gap + The guard path drops the authenticated identity: v2 handlers behind Digest auth could observe the resolved user via http_request::get_digested_user() (src/httpserver/http_request.hpp:186); in v3, make_digest_guard (src/detail/auth_digest.cpp:493-517) discards digest_auth_verdict::username, so a wrapped handler cannot learn who authenticated. The same shape was accepted for basic auth in TASK-114 and no parity-inventory row pins it, so this is a consistent v3 design delta rather than a regression introduced here, but it is an externally observable v2 capability with no v3 equivalent in the guard flow. + *Recommendation:* Record the delta for the v2-to-v3 migration guide, or introduce an exchange/request-scoped identity seam (surfacing verdict.username for guard-wrapped handlers) in the milestone task that owns the request-identity surface; no TASK-115 change is strictly required. + +25. [ ] **spec-alignment-checker** | `src/httpserver/detail/digest_params.hpp:170` | specification-gap + Quoted-string parsing is stricter than RFC 7230 section 3.2.6: qdtext permits raw HTAB inside quoted-strings, but parse_quoted rejects every CTL including 0x09 via is_ctl (src/httpserver/detail/digest_params.hpp:110-113), so a client quoting a tab inside a Digest param value is classified malformed_credentials (401 re-challenge). The header documents the 'no control octet anywhere' rule but not that it deviates from the RFC grammar; the deviation is a deliberate hardening and real-world Digest params do not carry tabs, so impact is negligible. + *Recommendation:* Either accept raw HTAB inside quoted-string values to match RFC 7230 qdtext, or state explicitly in the digest_params.hpp header comment that rejecting in-quote HTAB is an intentional deviation from the RFC grammar (bounded-parsing posture). + +26. [ ] **spec-alignment-checker** | `test/unit/digest_auth_policy_test.cpp:null` | acceptance-criteria + The legacy qop-absent (RFC 2617) acceptance path has no policy-level test evidence. The frozen baseline scope includes 'qop=auth and legacy qop-absent'; compute_response_legacy is pinned against RFC 7616/RFC 2617 vectors and cross-checked against the independent test-side MD5 (test/unit/digest_response_vector_test.cpp:127-146), but no test sends a qop-less Authorization through digest_auth_policy::check(), so material_accepts' qop.empty() branch (src/detail/auth_digest.cpp:188), nc_value's implicit nc=1 (src/detail/auth_digest.cpp:133-137), and replay of a legacy request are all uncovered by any green test. + *Recommendation:* Add a policy test that answers an offered challenge with the legacy no-qop formula (qop/nc/cnonce absent) and asserts authenticated, then re-presents the same Authorization and asserts replayed_nonce with no stale hint. + +27. [ ] **spec-alignment-checker** | `test/unit/digest_auth_policy_test.cpp:null` | action-item + Plan section 6.1 names the behavior 'last_nc advances even when verification later fails' (a failed guess burns its nc; the ledger admits before password verification in gate_nonce), but no test observes it at the policy level: wrong_material_is_rejected checks each failing material exactly once, and e2e test 33 sends a single wrong-password attempt. The burn-nc anti-replay property is therefore untested end to end. + *Recommendation:* Extend wrong_material_is_rejected (and optionally e2e) to re-check the identical wrong-password Authorization and assert the result is replayed_nonce (401, no stale) rather than another credentials_rejected verification. + +28. [ ] **test-quality-reviewer** | `test/integ/native_http1_e2e_test.cpp:422` | missing-test + The empty-challenge-body branch of make_digest_guard (src/detail/auth_digest.cpp lines 504-506: verdict.challenge_body.empty() -> plain x.respond() with the Content-Length: 0 framing) is never executed by any digest test: every /digest* e2e route (lines 422-427) and every policy test configures challenge_body, and the fabricated nonce_unavailable verdict test only inspects challenge_fields() without the guard. The default-empty-body 401 framing is consequently unpinned for Digest. + *Recommendation:* Add one e2e (or guard-level) scenario with default options (empty challenge_body) asserting a 401, Content-Length: 0, empty body, and the WWW-Authenticate challenge. + +29. [ ] **test-quality-reviewer** | `test/unit/digest_auth_policy_test.cpp:183` | missing-test + The challenge's realm escaping is untested: append_escaped (src/detail/auth_digest.cpp lines 97-106) backslash-escapes quote and backslash in the realm, and the factory deliberately accepts such realms (only CR/LF/NUL refused, verified in factory_validates_inputs), but no test creates a realm containing '\"' or '\\' and asserts the emitted challenge carries the escaped form (and that the independent client's parse_www_authenticate round-trips it). + *Recommendation:* Extend the challenge-shape coverage with one policy whose realm contains a quote and a backslash; assert the challenge value contains the backslash-escaped spellings and that parse_www_authenticate recovers the original realm. + +30. [ ] **test-quality-reviewer** | `test/unit/digest_auth_policy_test.cpp:302` | slow-test + Two tests age out a ttl=0 nonce by sleeping 1100 ms against the wall clock (digest_auth_policy_test.cpp:302 and test/integ/native_http1_e2e_test.cpp:1479; the e2e test measured 1115 ms in a verified run). The outcome is deterministic (100 ms margin over the 1-second boundary) and the policy has no clock seam, so it is an acceptable tradeoff, but it adds ~2.2 s to the suite and depends on second-granularity time + *Recommendation:* If a policy-level clock seam is ever introduced (classify_nonce already takes now_unix, demonstrating the pattern), replace both sleeps with injected time; otherwise leave as-is but keep the margin documented. + +31. [ ] **test-quality-reviewer** | `test/unit/digest_auth_policy_test.cpp:309` | logic-in-test + expired_nonce_is_stale draws two different cnonces: compute_response_cleartext signs with one make_cnonce() (line 309) while build_authorization_header ships another (line 311), contradicting the single-draw convention this very file documents in answered_authorization (lines 104-105, 'two draws would sign one value and send another'). The shipped Authorization could never authenticate; the test passes only because expiry classification precedes response verification, silently coupling the test to the pipeline order rather than to the stale behavior it names. + *Recommendation:* Draw the cnonce once into a local variable and pass it to both the response computation and the header build, matching answered_authorization. + +32. [ ] **test-quality-reviewer** | `test/unit/digest_auth_policy_test.cpp:446` | missing-test + The concurrency smoke uses eight threads with eight distinct challenges, so the ledger mutex's actual guarantee from plan section 3 -- 'racing identical nc -> exactly one authenticated/one replayed' -- is never exercised; concurrent_rounds_authenticate would pass even if admission were not serialized (each thread hits a different slot). + *Recommendation:* Add a variant where all threads answer the SAME challenge at nc=00000001: assert exactly one authenticated and seven replayed_nonce. diff --git a/specs/unworked_review_issues/task-116_validation_5e1da7c910049e9ef99a36f61baa2afc.md b/specs/unworked_review_issues/task-116_validation_5e1da7c910049e9ef99a36f61baa2afc.md new file mode 100644 index 000000000..216130ebc --- /dev/null +++ b/specs/unworked_review_issues/task-116_validation_5e1da7c910049e9ef99a36f61baa2afc.md @@ -0,0 +1,81 @@ +# Unworked Review Issues + +**Run:** 2026-10-02 05:57:53 +**Task:** TASK-116 +**Total:** 18 (0 critical, 2 major, 16 minor) + +## Major + +1. [ ] **code-simplifier** | `src/httpserver/detail/forms_urlencoded.hpp:140` | code-structure + The escape accumulator resets escape_digits_ but not escape_value_ when '%' enters escape state (lines 139-142), yet feed_escape accumulates as escape_value_ = escape_value_ * 16 + hex_value(c) (line 163). Correctness of a second escape in the same body (e.g. "p=%2F&q=%2f") rests entirely on escape_value_ being exactly unsigned char: the stale byte is shifted by 16 twice (x256) and vanishes modulo 256, so the truncated result is accidentally right. Verified empirically: unsigned char yields 0x2f, but a widened accumulator (unsigned) yields 0x2f2f. A reader must do modular arithmetic to prove the tests pass; widening the member type or changing the digit count silently corrupts every escape after the first. + *Recommendation:* Make the reset explicit and behavior-identical: in feed_byte's '%' case add escape_value_ = 0; beside escape_digits_ = 0;. One line, removes the implicit mod-256 invariant the state machine currently depends on. + +2. [ ] **test-quality-reviewer** | `test/unit/forms_urlencoded_route_test.cpp:332` | missing-test + The frozen baseline states urlencoded_limits{max_total_bytes, max_fields} overrun -> 413 handler-never-invoked, but the adapter's field-count overrun path is never exercised end to end. make_urlencoded_route has two distinct 413 branches: the collect-level branch (src/detail/forms_urlencoded.cpp:171-181, byte overrun, responds with EMPTY fields) and the decode-level branch (src/detail/forms_urlencoded.cpp:193-201, responds via form_read::reject_status()/reject_fields() with Content-Length: 0). Route test (3) and e2e (36) cover only the byte-cap/collect branch; the malformed-400 test covers the decode-failure branch only with invalid_argument. A body with max_fields+1 decoded pairs through the route (e.g. limits{65536, 2} with 'a=1&b=2&c=3') has no test anywhere outside the decoder/vocabulary units, so the observable 413 + CL:0 combination that branch produces is unpinned. + *Recommendation:* Add one route-level case (and optionally one e2e case) with a field-capped urlencoded_limits: assert 413, handler invocation count 0, and responded Content-Length '0' -- proving the decode-limit branch of the adapter, including its framing difference from the collect-level 413. + +## Minor + +3. [ ] **architecture-alignment-checker** | `specs/architecture/v3/v2-parity-inventory.md:86` | interface-contract + The TASK-116 migration note edits the forms row to say 'decode within cap identical to v2: first-`=` split, `+` as 0x20, strict `%HH`, arrival-order repeats, first-value lookup', but 'strict %HH' is listed inside the identical-to-v2 enumeration while delta (1) of the same cell correctly records that v2 passed malformed escapes through literally -- strictness is exactly the delta, not the parity. The public header words it correctly ('%HH is the byte', src/httpserver/forms/urlencoded.hpp:30). The inventory is the frozen parity contract baseline (PRD-V3N-REQ-038, architecture section 5 gate 5), so the self-contradictory enumeration should be precise. All other claims in the edited cell check out: defaults 65536/64 equal v2's DEFAULT_MAX_ARGS_BYTES/DEFAULT_MAX_ARGS_COUNT (src/httpserver/detail/http_request_impl.hpp:379-380), and the three cited v2 knobs exist (src/httpserver/create_webserver.hpp:143,179-180). + *Recommendation:* Reword the enumeration to 'well-formed `%HH` decodes identically (malformed `%HH` is delta 1 below)' so the parity column states only what is actually identical and the delta column carries the strictness change. + +4. [ ] **architecture-alignment-checker** | `src/detail/forms_urlencoded.cpp:158` | pattern-violation + make_urlencoded_route() throws std::invalid_argument at registration time for a zero cap or an empty handler, while every sibling v3 factory/registration validation returns a typed http::outcome instead: urlencoded_limits::create() in the same TU (forms_urlencoded.cpp:83-93), basic_auth_policy::create() and the digest create() (src/httpserver/auth/basic_auth.hpp:122-129), route_registry::route() (src/httpserver/server/routes.hpp:272-312), and native_server::route_sync() (src/httpserver/server/server.hpp:137), whose make_sync_route counterpart delegates its zero-cap rejection to that typed registration check (route_sync.hpp:103-104). The v3 architecture names typed results as the public-lifecycle driver (specs/architecture/v3/architecture.md section 2 driver table) and typed libhttpserver errors for public operations (section 5). The throw is documented in the public header (src/httpserver/forms/urlencoded.hpp:196-198) and confined to pre-listen registration time, so it does not break the request-path no-exception rule. + *Recommendation:* Either validate through a typed create-style seam consistent with urlencoded_limits::create() and the auth factories (e.g. an out-param factory or delegating the cap check to the typed native_server::route_sync registration as make_sync_route does), or add one sentence to the forms header documenting the throw as the deliberate exception to the typed-results convention so later v3 components do not copy it as precedent. + +5. [ ] **code-quality-reviewer** | `src/detail/forms_urlencoded.cpp:59` | readability + Two constant-naming styles coexist in the same anonymous namespace: k_content_type_field / k_urlencoded_media_type (snake with k_ prefix) and kReadChunkBytes (camel k prefix). The wider codebase mixes both styles across files, but within a single 150-line TU the inconsistency is visible. + *Recommendation:* Rename kReadChunkBytes to k_read_chunk_bytes (or the two string constants to camel k style) so one file uses one convention. + +6. [ ] **code-quality-reviewer** | `src/httpserver/detail/forms_urlencoded.hpp:139` | code-elegance + The '%' case resets escape_digits_ but not escape_value_, so the second and later escapes accumulate over the previous escape's byte value and are only correct because unsigned-char assignment truncates modulo 256 ((old*16+d1)*16+d2 == old*256 + d1*16+d2, and old*256 vanishes mod 256). This is functionally correct today and covered by tests (escapes_survive_feed_splits, %41 after %2F), but it is a subtle latent trap: the invariant is nowhere stated in the code, and any future change to the accumulator type or digit count silently breaks it. + *Recommendation:* Set escape_value_ = 0 alongside escape_digits_ = 0 in the '%' case of feed_byte (or note the mod-256 reasoning in a one-line comment), so correctness no longer depends on integer wraparound. + +7. [ ] **code-quality-reviewer** | `test/unit/forms_urlencoded_corpus_test.cpp:131` | test-maintainability + The corpus replay introduces ~90 lines of one-off HTTP request-line/header parsing (split_lines + parse_case) that assumes exactly one space after the colon (line.substr(colon + 2) would drop the first character of 'Header:value') and no obs-fold lines. It is correct for the pinned forms.tseq, but TASK-117 (multipart_field replay) will need the same wire-to-request_head scaffolding and is poised to copy it, growing unshared parser logic in the test tree. + *Recommendation:* When TASK-117 lands, promote parse_case/split_lines into a shared parity helper (test/parity/) with tolerant colon-space handling instead of duplicating them into the multipart corpus test; optionally fix the single-space assumption now. + +8. [ ] **code-quality-reviewer** | `test/unit/forms_urlencoded_route_test.cpp:651` | test-coverage + read_urlencoded's failure modes are only partially pinned: the happy segmented path, the malformed verdict, and the decoder-side byte cap are covered, but the documented invalid_state verdict for an exchange whose body was already admitted (urlencoded.hpp:184-186), a transport failure mid-stream (disconnect while parked in read_some), and the empty-body streaming read (stage_end with no segments) have no direct assertions. The adapter's disconnect path is covered (test 9), so the gap is specific to the streaming form. + *Recommendation:* Add one or two stream_read_diff-style probes: double-admission returning the invalid_state code, and a staged source disconnected mid-body returning a non-committable status with no fields. + +9.

The route test's own comment (test/unit/forms_urlencoded_route_test.cpp:601-602) calls it 'the same rule urlencoded_limits::create ... encode[s]'. + *Recommendation:* Validate via the factory and throw on its rejection (e.g. if (!urlencoded_limits::create(limits.max_total_bytes, limits.max_fields, limits).ok() || !handler) throw std::invalid_argument(...)), keeping create() the single source of the rule.

[ ] **housekeeper** | `specs/architecture/v3/v2-parity-inventory.md:86` | spec-not-updated + The plan's out-of-scope decision that query-string/GET-argument parsing belongs to the request-head area (raw_target/route_path vocabulary) and that the TASK-116 form surface handles request bodies only is not recorded in any committed artifact: the TASK-116 migration note added to the forms row does not mention it, the public header's scope comment says 'request bodies' without saying where query-string args will live, no M9 task covers it, and the explicit assignment exists only in the untracked .groundwork-plans/TASK-116-plan.md. The other deferrals are durably recorded (multipart in specs/tasks/M9-http1-parity-websocket/TASK-117.md plus the corpus-test and test/Makefile.am comments; the unescaper/knobs delta in the inventory note itself; the 415 posture as the documented v2-parity empty-fields behavior in src/httpserver/forms/urlencoded.hpp lines 49-54, pinned by form_route_wrong_type_empty_fields). + *Recommendation:* Add one clause to the TASK-116 migration note in the forms row of specs/architecture/v3/v2-parity-inventory.md (or to the scope comment in src/httpserver/forms/urlencoded.hpp) stating that query-string/GET-argument parsing is request-head area scope and deliberately not part of the form adapter, so the deferral survives outside the session-local plan file. + +12. [ ] **performance-reviewer** | `src/httpserver/server/route_sync.hpp:129` | memory-allocation + The commit-tail extraction makes make_sync_route co_await detail::commit_sync_value (defined at line 78) once per request, adding one task coroutine invocation to the pre-existing sync route; each task frame is heap-allocated and its task_frame_base constructs a std::make_shared() (src/httpserver/concurrency/task.hpp:124-126), so unless the compiler elides the coroutine allocation the sync route gains a small constant allocation pair per request. The extracted body is byte-identical to the previous inline tail (verified against the base diff), value is moved in, and asymptotic behavior is unchanged. + *Recommendation:* Accept as-is: the route already co_awaits several tasks per request (collect, writer().write, writer().finish) so this is one more small constant among several, and the plan (section 7, duplication-lane risk) explicitly mandated factoring the shared commit tail into a detail:: helper. If the sync route ever shows up in allocation profiles, confirm coroutine heap-allocation elision at -O2 (or annotate the call for await elision) before considering re-inlining. + +13. [ ] **security-reviewer** | `src/httpserver/forms/urlencoded.hpp:84` | documentation + The installed public header's rationale for refusing zero caps is inaccurate: "a cap of zero would disable the bound, so create() refuses both." A zero cap does not disable any bound. Verified behavior is fail-closed in the opposite direction: the decoder trips limit_exceeded on the first consumed byte (bytes_seen_ >= 0 check at src/httpserver/detail/forms_urlencoded.hpp:92) and on the first committed field (fields_.size() >= 0 check at :182), and make_urlencoded_route throws std::invalid_argument at registration (src/detail/forms_urlencoded.cpp:158-163). No unbounded path exists; only the stated justification is wrong. The residual risk is documentation-driven misuse: a future maintainer believing zero was intended as 'unlimited' could relax validation in that direction. CWE-1078 (inaccurate security-relevant comment). + *Recommendation:* Reword the comment to state the actual semantics, e.g. "a cap of zero is meaningless (it admits nothing), so create() and make_urlencoded_route refuse it so misconfiguration fails fast." No code change required. + +14. [ ] **spec-alignment-checker** | `src/detail/forms_urlencoded.cpp:66` | ears-requirement + PRD-V3N-REQ-038 requires observable behavior changes to be explicitly recorded in a migration note. v2's form activation gate (src/detail/request_pipeline.cpp:147-150) is an unanchored case-insensitive prefix strncasecmp, so a Content-Type such as 'application/x-www-form-urlencoded2' still activated urlencoded form processing in v2. The v3 gate is_urlencoded_content_type (src/detail/forms_urlencoded.cpp:66-79) requires the media type to end at the value or be followed by ';', ' ' or '\t', so such a suffix-extended type now bypasses decoding and reaches the handler with empty fields. The tightening is deliberate and pinned by test (test/unit/forms_urlencoded_route_test.cpp:449-467, form_route_wrong_type_empty_fields) and documented in the public header comment (src/httpserver/forms/urlencoded.hpp:50-54), but the TASK-116 migration note in specs/architecture/v3/v2-parity-inventory.md does not record this gate-boundary change. + *Recommendation:* Extend the TASK-116 entry in specs/architecture/v3/v2-parity-inventory.md to record that the v3 content-type gate requires the urlencoded media type to end at the value or be followed by a parameter/whitespace boundary, where v2's prefix match also accepted suffix-extended types (e.g. 'application/x-www-form-urlencoded2'). + +15. [ ] **test-quality-reviewer** | `test/unit/forms_urlencoded_route_test.cpp:239` | implementation-coupling + The streaming helpers assert on numeric enum renderings: stream_malformed_diff expects the string "code:1" (line 239) and stream_overcap_diff expects "code:3" (line 249), hardcoding the numeric values of http::outcome_code::invalid_argument and limit_exceeded from src/httpserver/http/outcome.hpp:37-48. A future enum insertion between entries would break these tests with no behavior change. The explanatory comments mitigate but do not remove the coupling. + *Recommendation:* Have the helpers compare read.status.code() directly against the http::outcome_code enumerators and return a bool/diff, or render the code through a stable name, so the expected value travels as the enumerator rather than its ordinal. + +16. [ ] **test-quality-reviewer** | `test/unit/forms_urlencoded_route_test.cpp:479` | naming-convention + form_route_type_boundaries loops over three Content-Type values with bare LT_CHECKs inside the loop body (lines 479-497); a failure reports only the check text, not which content type was under test, unlike the decoder helpers which embed the split index (k=) in every diff message. + *Recommendation:* Render the current type into the assertion path (e.g. a per-type diff string like the file's helper convention, or an LT_CHECK on a formatted 'type= rendered=' comparison) so a regression names the failing boundary case. + +17.

This is documented public-surface behavior, though not named in the frozen baseline. + *Recommendation:* Add a stream_read_diff-style case that calls x.admit_body(...) before spawning read_urlencoded and asserts the invalid_state verdict with no decoder activity. + +18. [ ] **test-quality-reviewer** | `test/unit/urlencoded_decoder_test.cpp:295` | logic-in-test + Two sweep loops live directly in test bodies instead of the file's established diff-string helper convention: the truncated-escape split loop (lines 295-301, whose LT_CHECK failures do not carry the split index k) and the single-byte feed loop in byte_cap_boundary (lines 366-372). The helpers in the same file (every_split_decodes_to, segmented_decodes_to) show the intended pattern with index-tagged diagnostics. + *Recommendation:* Move both sweeps into helpers returning index-tagged diff strings (e.g. 'split k=2: ...') and LT_CHECK the empty diff, matching every_split_decodes_to; or at minimum embed std::to_string(k) into the loop's failure messages. diff --git a/specs/unworked_review_issues/task-117_validation_b3f9e278818b184677cc03b186ba481f.md b/specs/unworked_review_issues/task-117_validation_b3f9e278818b184677cc03b186ba481f.md new file mode 100644 index 000000000..e42e4cb7a --- /dev/null +++ b/specs/unworked_review_issues/task-117_validation_b3f9e278818b184677cc03b186ba481f.md @@ -0,0 +1,131 @@ +# Unworked Review Issues + +**Run:** 2026-10-02 10:52:38 +**Task:** TASK-117 +**Total:** 30 (0 critical, 4 major, 26 minor) + +## Major + +1. [ ] **code-quality-reviewer** | `src/httpserver/detail/forms_multipart.hpp:302` | error-handling + multipart_decoder's constructor is declared noexcept but performs two heap allocations: needle_(" +--" + boundary) (line 307) and pending_.assign(" +", 2) (line 314). A failing allocation inside a noexcept constructor calls std::terminate(), turning a per-connection failure into a process-wide crash. This is inconsistent with the surface's own discipline (typed outcomes, never exceptions/termination on the request path) and with the TASK-116 urlencoded_decoder, whose noexcept constructor (forms_urlencoded.hpp:81-83) allocates nothing. Both construction sites (decode_multipart at forms_multipart.cpp:255 and read_multipart at forms_multipart.cpp:285) run on the request path. + *Recommendation:* Drop the noexcept from the multipart_decoder constructor (an escaping bad_alloc is captured by the task/runner error path), or precompute the needle without a temporary concatenation and reserve pending_ capacity so noexcept is honest. Verified all other allocation-performing members (feed, pump paths) are non-noexcept, so the constructor is the only dishonest annotation. + +2. [ ] **code-simplifier** | `src/detail/forms_multipart_files.cpp:59` | code-structure + sanitize_upload_filename(std::string_view) is defined with external linkage directly in namespace httpserver (the library's root namespace) with no declaring header and no user outside this TU -- it is only called at forms_multipart_files.cpp:180. It is therefore an accidentally exported symbol of the shared library (symbol pollution and an ODR trap for any downstream definition of httpserver::sanitize_upload_filename). It is also inconsistent with the file's own sibling helper hex_byte (line 74), which correctly lives in the anonymous namespace, and with the TASK-116 convention in forms_urlencoded.cpp/forms_multipart.cpp whose free helpers are all anonymous-namespace. It is additionally a near-verbatim re-implementation of the existing, tested http_utils::sanitize_upload_filename (src/http_utils.cpp:279, pinned by test/unit/http_utils_test.cpp:953-1041); re-implementing it inside v3core is defensible under DR-V3-001 (v3core owns its primitives, no v2 TU dependency), but then it must be TU-local. + *Recommendation:* Move sanitize_upload_filename into the existing anonymous namespace at the top of src/detail/forms_multipart_files.cpp (merging it with hex_byte's block). Behavior-preserving, one-block edit; no header, test, or Makefile change is needed since nothing references it externally. + +3. [ ] **code-simplifier** | `src/detail/forms_multipart_files.cpp:59` | code-structure + Prior finding code-simplifier-iter1-2: httpserver::sanitize_upload_filename is exported (non-detail namespace) although only the multipart files sink uses it. Confirmed still present and unworked. Coordinator has ruled it OUTSIDE the repair envelope; recorded here only so the unworked-findings ledger persists it. Not blocking. + *Recommendation:* Defer to a later task with the envelope to internalize the symbol (detail namespace + header move); no action in this validation. + +4. [ ] **performance-reviewer** | `src/httpserver/detail/forms_multipart.hpp:505` | algorithmic-complexity + pump_headers() calls pending_.erase(0, nl + 1) once per header line inside its loop, and each front-erase memmoves the entire remaining pending_ buffer. Under the streaming path (read_multipart feeds <=512 bytes, so pending_ stays <= feed + holdback) this is bounded and harmless, but under a single large feed -- exactly what the public installed one-shot forms::decode_multipart does via decoder.feed(body) -- pending_ holds the whole body while each of up to ~max_part_header_bytes/3 stored lines (a minimal stored line is one char + CRLF; the colon check happens later in record_header, so even junk lines count) shifts the full remaining tail. Worst case is O(lines x remaining) = ~cap^2/6 byte-moves: with the default 64 KiB max_total_bytes an adversarial body (short-line header blocks padded before a bulk tail) forces on the order of hundreds of MiB of memmove (~10,000x amplification of the input), and the amplification factor grows linearly with a caller-raised max_total_bytes (the e2e disk route already uses 16 MiB; an app one-shotting at that cap reaches tens of GiB of memmove per request). This is bounded by caps and NOT reachable through make_multipart_route/read_multipart (the server hot path), which is why it is major rather than critical. + *Recommendation:* Consume header lines with a cursor instead of erasing per line, mirroring pump_body's from-offset technique: advance a consumed offset past each line (copying the line into lines_ as today), and perform one pending_.erase(0, consumed) when pump_headers exits (need_more, failure, or blank-line transition to begin_part). That makes the per-feed cost O(pending_) once per feed for every feed size, removing the quadratic for one-shot callers with no behavior change (the every_split matrix in test/unit/multipart_decoder_test.cpp is the regression net). + +## Minor + +5. [ ] **architecture-alignment-checker** | `src/detail/forms_multipart.cpp:103` | interface-contract + A sink failure returned from on_part_end() fires no on_part_abort for that part, diverging from the documented blanket contract. sink_event_adapter::on_part_end() (src/detail/forms_multipart.cpp:103-107) clears in_flight_ and increments completed_ before invoking sink_.on_part_end(); when the sink returns a failure from on_part_end(), the decoder adopts it as the sticky terminal but forward_abort() is then a no-op for that part. The public header (src/httpserver/forms/multipart.hpp:40-44) and the parity inventory both state on_part_abort fires for the begun-but-unended part on "any sink-returned failure". The in-tree temp sink self-cleans on this path (temp_file_part_sink::on_part_end discards the partial on close failure, src/detail/forms_multipart_files.cpp:224-233), and the test suite's failing_sink only fails from on_part_data (test/unit/forms_multipart_test.cpp:112-135), so the edge is untested and a custom sink written against the documented wording could skip its own cleanup expecting the abort notification. + *Recommendation:* Either move the in_flight_/completed_ bookkeeping after the sink call in sink_event_adapter::on_part_end() so a failing end also delivers on_part_abort, or narrow the documented contract in forms/multipart.hpp and v2-parity-inventory.md ("a failure returned from on_part_end means the sink has already settled the part; no abort follows") and pin the edge with a test case. + +6. [ ] **architecture-alignment-checker** | `src/httpserver/forms/multipart.hpp:248` | interface-contract + The default upload-name mode flipped relative to v2 without a migration-note clause, and the header comment misstates the v2 default. v2 defaults are file_upload_dir="/tmp" with generate_random_filename_on_upload=false (src/httpserver/create_webserver.hpp:182-183), i.e. sanitized client filenames by default; temp_file_options::random_names defaults to true (src/httpserver/forms/multipart.hpp:229). The TASK-117 migration note in specs/architecture/v3/v2-parity-inventory.md:87 documents both name modes but never records that the default changed, and the public header comment at line 248 reads "The v2 defaults: /tmp with random names and nothing kept", which is factually wrong about v2. PRD-V3N-REQ-038 and v3 architecture release gate 5 ("Every intentional behavior change receives a migration note") make the default flip a recordable observable change (the on-disk name pattern differs unless the application opts back into sanitized names). + *Recommendation:* Add one clause to the TASK-117 migration note in specs/architecture/v3/v2-parity-inventory.md recording the default flip (v2 default: sanitized client basename; v3 default: random name, restored via temp_file_options::random_names=false), and correct the comment at src/httpserver/forms/multipart.hpp:248 to "directory /tmp with nothing kept; v2 defaulted to client filenames, v3 defaults to random names (the security-first choice)". + +7. [ ] **code-quality-reviewer** | `src/detail/forms_multipart.cpp:67` | code-elegance + is_multipart_content_type (lines 67-80) is a near-verbatim copy of is_urlencoded_content_type (src/detail/forms_urlencoded.cpp:67-80); only the media-type constant differs. It sits under the PMD CPD 100-token threshold so the duplication gate still reports exactly its 2 accepted baseline blocks, but this is the second hand-copied instance of the same 14-line gate shape, and a third form surface would copy it again. + *Recommendation:* Hoist one shared bool matches_media_type(optional value, string_view type) helper into a small detail header (e.g. alongside detail/forms_verdict.hpp or auth_text.hpp) and let both TUs pass their media-type constant. The plan's own risk note (share matching between the form TUs) anticipated exactly this. + +8. [ ] **code-quality-reviewer** | `test/integ/native_http1_e2e_test.cpp:2102` | test-robustness + The disk scenarios assign the plain (non-atomic) global std::string e2e_disk_dir AFTER server_fixture construction has already started the server's accept/worker threads (line 2098 constructs the fixture, line 2102 writes; same ordering at line 2148), while the /upload_disk and /upload_slow handlers read it (lines 332, 362) on server threads. The ordering currently holds only through kernel syscall sequencing (write, then connect/send, then accept/spawn), which is not a formal C++ happens-before edge; a sanitizer build could report a data race on the string object. + *Recommendation:* Create the scratch directory and assign e2e_disk_dir BEFORE constructing server_fixture in tests 44 and 45 (thread creation then provides the happens-before edge for everything earlier), or capture the directory at route-registration time instead of through the global. + +9. [ ] **code-quality-reviewer** | `test/unit/forms_multipart_files_test.cpp:180` | test-maintainability + body_truncated (lines 180-195) duplicates body_of (lines 160-176) in full except for the withheld closing boundary line; 15 identical framing lines exist twice and will drift if the body shape ever changes. + *Recommendation:* Fold both into one builder taking a bool close_body (or have body_of append the tail and body_truncated call the same loop and skip the final tail append), keeping the single place that frames a part. + +10. [ ] **code-simplifier** | `src/detail/forms_multipart.cpp:105` | code-structure + Two counters track the same fact and can disagree: sink_event_adapter increments completed_ in on_part_end() before consulting the sink's return (line 103-107), while multipart_decoder::end_part_at increments parts_completed_ only when on_part_end succeeds. On a sink end-failure the adapter count is one higher than the decoder's, and read_multipart reports the adapter number in its failure verdicts (lines 297, 303, 309). The decoder already exposes parts_completed(), and it is in scope in both drivers, so the adapter's counter is redundant state whose semantics silently differ from the documented 'parts_completed counts them'. + *Recommendation:* Delete sink_event_adapter::completed_ and completed(), and source the count from decoder.parts_completed() at the four verdict-construction sites in decode_multipart (line 266) and read_multipart (lines 297, 303, 309, 311). On success the values are identical, so the change is behavior-preserving on the ok path and only tightens the informational count on failure paths. + +11. [ ] **code-simplifier** | `src/detail/forms_multipart.cpp:128` | patterns + The field-part collection contract ('non-file parts append name/value entries in arrival order; file parts are drained and never buffered') is implemented three times: field_collecting_sink in forms_multipart.cpp:128-165, the field_name_/field_value_/entries_ members and their on_part_data/on_part_end handling inside multipart_temp_state in forms_multipart_files.cpp:142-144 and 217-241, and the corpus test's field_sink in forms_multipart_corpus_test.cpp:82-116. Each copy is small and below CPD's threshold, but the contract now lives in three places that must move together. + *Recommendation:* Extract the minimal collect state (name, value, entries and the drain-or-append transition) into one internal helper type in a private detail header used by both TUs (the temp-file state can own one as a member); leave the test copy alone (DAMP). Optional consolidation -- flagging because TASK-117's own plan risk note asked for parameterization over copying between the form TUs. + +12. [ ] **code-simplifier** | `src/detail/forms_multipart.cpp:67` | patterns + is_multipart_content_type (forms_multipart.cpp:67-80) is a line-for-line copy of is_urlencoded_content_type (forms_urlencoded.cpp:67-80) with only the media-type constant changed; the shared constants k_content_type_field and kReadChunkBytes are likewise duplicated in both TUs' anonymous namespaces. The run sits just under PMD CPD's 100-token threshold, so the duplication gate cannot see it -- exactly the drift the forms_verdict.hpp extraction was created to prevent for the verdict shaping. + *Recommendation:* Parameterize once: a shared detail helper (e.g. matches_media_type(const std::optional&, std::string_view type) alongside or inside detail/forms_verdict.hpp, or a small detail/media_type.hpp) with each TU passing its media-type constant. Keeps the two v2 activation gates from diverging when one is touched. + +13. [ ] **code-simplifier** | `test/integ/native_http1_e2e_test.cpp:182` | patterns + e2e_scratch_dir (mkdtemp template, destructor that removes entries then the directory, readdir-based entries()) at lines 182-216 duplicates the unit suite's scratch_dir in forms_multipart_files_test.cpp:72-119; wait_dir_state/read_all likewise echo read_file-style helpers. Test-side duplication across the unit and integ trees -- tolerated under DAMP, but the two scratch-dir copies differ only in has()/size_of() versus empty(). + *Recommendation:* If a shared test utility home is acceptable (test trees already share test/parity), hoist one scratch-dir helper there; otherwise leave as-is and note the pair so a third copy does not appear. + +14. [ ] **code-simplifier** | `test/unit/forms_multipart_corpus_test.cpp:148` | patterns + The response-side corpus replay scaffold -- framer start_head/push_body/finish_body, response_frame_parser feed/finish, keepalive-verdict computation, and the expectation cursor walk with connection/closer special cases (lines 148-205) -- is a structural copy of forms_urlencoded_corpus_test.cpp's replay_case. The request-side half of this duplication was just promoted into test/parity/case_wire.hpp for exactly this reason (validation issue #7); the response half remains duplicated, so every future form corpus suite will copy it again. + *Recommendation:* Promote the response-side replay the same way: a parity helper taking (decoded body text, output fields, the parsed corpus_request) and returning the corpus diff, leaving each suite to supply only its decode step and echo posture. + +15. [ ] **code-simplifier** | `test/unit/forms_multipart_files_test.cpp:180` | patterns + body_truncated (lines 180-195) repeats body_of's framing loop (lines 160-176) byte-for-byte, differing only in withholding the final '--P9B--\r\n'; any framing edit must now be made twice in the same file. + *Recommendation:* One builder with a 'close' flag (append the final boundary only when true), or implement body_truncated as the shared builder minus the trailing delimiter; both keep the truncated shape readable at its call site. + +16. [ ] **code-simplifier** | `test/unit/forms_multipart_route_test.cpp:727` | code-structure + The positive-control arm of multipart_factory_validates (lines 726-734) catches std::invalid_argument and assigns threw = false -- the value it already holds -- so the subsequent LT_CHECK(!threw) can never fail: a spurious throw from the valid-argument call is silently swallowed and the arm asserts nothing. The contrast with the negative arms above (which set threw = true on the expected throw) makes the dead assignment easy to misread as the tested behavior. + *Recommendation:* Set threw = true inside this catch (or drop the try/catch and let an unexpected exception fail the suite), so the arm genuinely pins 'valid caps and a non-empty handler must not throw'. + +17. [ ] **housekeeper** | `specs/architecture/v3/v2-parity-inventory.md:86` | spec-not-updated + The deferral 'query-string/GET args belong to the request-head area (raw_target/route_path vocabulary), not the form adapters' named in the frozen baseline and in the TASK-117 plan's 'Deferrals (recorded, not silent)' list is still not recorded in any committed artifact. Verified: no M9 task file mentions query-string parsing (grep over specs/tasks/M9-http1-parity-websocket/ returns nothing), the TASK-116 urlencoded migration note and the new TASK-117 multipart note (line 87) do not mention it, src/httpserver/forms/urlencoded.hpp and src/httpserver/forms/multipart.hpp scope comments do not say where query-string args will live, and the only prior record of the decision is the untracked .groundwork-plans/TASK-116-plan.md plus the still-open TASK-116 unworked-review issue #11 (specs/unworked_review_issues/task-116_validation_5e1da7c910049e9ef99a36f61baa2afc.md, housekeeper finding) which documented this exact gap and recommended the same one-clause fix. TASK-117 was the plan-designated moment to land it and did not. + *Recommendation:* Add one clause to the forms rows of specs/architecture/v3/v2-parity-inventory.md (or the scope comment in src/httpserver/forms/urlencoded.hpp / multipart.hpp) stating that query-string/GET-argument parsing is request-head area scope and deliberately not part of the form adapters, closing unworked issue #11 from the TASK-116 validation. If swept more broadly, run /groundwork-source-product-specs-from-code. + +18. [ ] **housekeeper** | `specs/architecture/v3/v2-parity-inventory.md:87` | spec-not-updated + Two deferrals enumerated in the frozen baseline and the TASK-117 plan's 'Deferrals (recorded, not silent)' list have no durable record anywhere in the diff or the repo: (a) 'Transfer-Encoding: chunked multipart bodies beyond what the engine's body source already normalizes' -- the only 'chunked' mentions in the new files are decoder feed segmentation ('chunked feed at' in test/unit/multipart_decoder_test.cpp:228) and the pre-existing TASK-116 urlencoded e2e, with no note in the multipart migration cell or src/httpserver/forms/multipart.hpp; (b) 'no raw-body-dump equivalents' -- v2's debug_dump_request_body has no not-ported note in either forms cell (the adjacent TASK-116 cell covers put_processed_data_to_content/unescaper knobs, and the multipart cell's delta (1) covers set_arg_flat, but the raw-body-dump posture for multipart bodies is stated nowhere). The plan file itself (.groundwork-plans/TASK-117-plan.md, line 48) is untracked, so the decisions currently survive only outside the repository. + *Recommendation:* Extend the TASK-117 migration note (or the multipart.hpp scope comment) with one deferral sentence: chunked-Transfer-Encoding multipart bodies are consumed only through the engine body source's normalization, and v2's raw-body-dump/put_processed_data_to_content postures have no v3 forms equivalent (file bytes are obtained via a caller part_sink). Run /groundwork-source-product-specs-from-code if consolidating spec deltas. + +19. [ ] **performance-reviewer** | `src/detail/forms_multipart.cpp:177` | memory-allocation + run_multipart_route's non-multipart content-type branch (the v2-gate drain) uses co_await x.body().collect(caps.max_total_bytes), and body_reader::collect buffers the entire admitted body into a growing heap vector (body_reader.hpp:346-371) whose bytes are then discarded untouched -- unlike the urlencoded adapter it mirrors (forms_urlencoded.cpp:167-184), which actually decodes the collected bytes. A POST with a non-multipart Content-Type against a route configured with a large max_total_bytes therefore pays an O(cap) heap allocation and copy purely to throw the data away, exactly the posture the streaming branch was built to avoid. + *Recommendation:* Drain with a bounded read_some loop into a reused ~512-byte stack scratch (counting bytes against max_total_bytes to preserve the exact-at-cap and over-cap 413 semantics collect() provides) so the discard path is O(1) memory regardless of the caller's cap. Low urgency: it is bounded by the caller-chosen cap and consistent with the TASK-116 precedent, so it can ride a later cleanup. + +20. [ ] **security-reviewer** | `src/detail/forms_multipart.cpp:104` | contract-violation + Abort-once contract gap on sink-failed on_part_end: sink_event_adapter::on_part_end clears in_flight_ and increments completed_ BEFORE calling sink_.on_part_end(); when the sink's on_part_end returns failure the decoder goes sticky-failed, yet forward_abort finds in_flight_==false and never delivers on_part_abort for that begun part. The public contract (forms/multipart.hpp:40-44: on_part_abort fires 'on every non-ok terminal ... and any sink-returned failure') and the frozen baseline ('on_part_abort fires exactly once per begun part on every non-ok terminal ... sink failure') read as covering this terminal. The shipped temp_file_part_sink cleans up in its own failure branch (forms_multipart_files.cpp:226-233 calls discard_partial before returning the error), so no orphan results there, but a third-party sink relying on the documented signal after a failed end gets nothing, and multipart_read.parts_completed counts the failed part. + *Recommendation:* Fire on_part_abort when sink_.on_part_end() returns non-ok (discard_partial/on_part_abort are already idempotent for the temp sink), or explicitly document that a sink-returned on_part_end failure is the sink's own cleanup responsibility and is excluded from the abort guarantee. + +21. [ ] **security-reviewer** | `src/detail/forms_multipart_files.cpp:107` | input-validation + An empty temp_file_options.directory is not validated: random_path (line 107) and the sanitized path (line 186) build directory_ + '/' + name, so an empty directory yields root-anchored paths ('/lht-upload-...' or '/'), attempting writes at the filesystem root when the process is privileged. This is caller misconfiguration rather than attacker input (the client cannot set the directory), but the constructor accepts it silently. + *Recommendation:* Reject an empty directory at temp_file_part_sink construction with a typed invalid_argument (or default it to the '/tmp' default the parameterless constructor uses). + +22. [ ] **security-reviewer** | `src/detail/forms_multipart_files.cpp:189` | file-handling + TOCTOU/link-following window in file creation (CWE-59/CWE-377): on_part_begin pre-unlinks the destination (std::remove) and then opens with std::ofstream trunc, which follows symlinks. In sanitized-name mode the on-disk name is client-predictable, so in a shared or hostile directory a local racer can place a symlink between remove() and open() and have the library truncate/overwrite an arbitrary file the process can write; the client can also name-target existing files in the destination directory for unlink/overwrite. This is exact v2 parity (upload_pipeline's pre-unlink), and the default random-names mode (128 bits from the fail-closed entropy seam) makes the race impractical, so the residual risk requires sanitized mode plus a hostile shared directory. + *Recommendation:* Create with O_CREAT|O_EXCL semantics (a small platform shim mirroring entropy_sys.hpp; v2's generate_random_filename already used mkstemp-style uniqueness) and reject or re-draw on collision instead of pre-unlinking; skip the pre-remove entirely in random-names mode where trunc already suffices. + +23. [ ] **security-reviewer** | `src/httpserver/forms/multipart.hpp:241` | documentation-mismatch + The public contract overstates traversal rejection: the header states a 'traversal-shaped name is a typed invalid_argument rejection', but sanitize_upload_filename (src/detail/forms_multipart_files.cpp:59-70) only rejects empty/'.'/'..'/NUL-containing names; prefix traversal such as '../report.txt' or '/etc/passwd' is NEUTRALIZED to its basename and accepted (files test 'sanitized_names' pins decode-OK for '../report.txt'). The containment property itself holds — a basename can never contain '/', '\' or NUL, so the constructed directory + '/' + basename cannot escape the destination directory — and this is exact v2 parity (src/http_utils.cpp:279), but the documented behavior and the frozen-baseline wording ('traversal must be rejected') do not match the implemented neutralize-then-accept semantics. + *Recommendation:* Either align the documentation ('a traversal prefix is neutralized to the basename; only an unusable basename is a typed rejection') or tighten the sanitizer to 400 on any name containing a path separator. Also note control characters other than NUL survive sanitization (v2 parity; names like 'a\nb' become filenames) — consider rejecting C0 controls for hardening. + +24. [ ] **spec-alignment-checker** | `src/httpserver/forms/multipart.hpp:248` | specification-gap + The default-constructed temp_file_part_sink flips v2's on-disk name default without an explicit migration-note entry, and the header comment misstates the v2 default. v2 defaults generate_random_filename_on_upload = false (src/httpserver/create_webserver.hpp:183), so v2 disk uploads landed under sanitized client basenames; v3 defaults temp_file_options::random_names = true (multipart.hpp:229). The comment at line 248 ('The v2 defaults: /tmp with random names and nothing kept') is factually wrong about 'random names' ('/tmp' and 'nothing kept' are correct: create_webserver.hpp:182, :190 + http_request.cpp:165-185). The parity-inventory migration cell (specs/architecture/v3/v2-parity-inventory.md:87) says 'random or sanitized basenames under a directory' but never records that the default changed from client-sanitized to random. The created file name is externally observable, and PRD-V3N-REQ-038 requires such changes to be explicitly recorded in a migration note. + *Recommendation:* Correct the comment at src/httpserver/forms/multipart.hpp:248 to state the actual divergence (v2 defaulted to sanitized client names; v3 defaults to random names via the entropy seam), and append one clause to delta (1) of the multipart migration cell in specs/architecture/v3/v2-parity-inventory.md recording the default flip. + +25. [ ] **spec-alignment-checker** | `test/Makefile.am:1417` | specification-gap + Stale comment in the forms_urlencoded_corpus block: 'multipart_field stays with the v2 transcript_runner lane until TASK-117'. TASK-117 has now landed the v3 replay (forms_multipart_corpus, added directly below at line 1423), so the 'until TASK-117' note is obsolete and misleads a reader about where the case is pinned. + *Recommendation:* Reword the comment to state that urlencoded_echo replays here and multipart_field replays in forms_multipart_corpus (the v2 transcript_runner lane still covers both as the v2 baseline). + +26. [ ] **test-quality-reviewer** | `test/integ/native_http1_e2e_test.cpp:2052` | missing-test + The bounded-upload scenario (http11_multipart_over_cap_413) declares 256 KiB (`declared = 256 << 10`), i.e. 4x the route's 64 KiB byte cap, while the frozen plan section 4(b) and the validation baseline specify "a multi-MiB multipart body against a small-capped route". The mechanism (reject long before the client finishes, drain the remainder, reuse the connection) is exercised, and the multi-MiB upload itself lands in scenario (45), but the 413 path is not proven at multi-MiB scale as enumerated. + *Recommendation:* Raise the declared body to multi-MiB (the send loop and 5 s deadline already accommodate it), or record the 4x-cap substitution as a deliberate deviation in the test comment. + +27. [ ] **test-quality-reviewer** | `test/unit/forms_multipart_files_test.cpp:312` | missing-test + The sanitizer's empty-basename branch is untested: sanitize_upload_filename (src/detail/forms_multipart_files.cpp:59-70) rejects a filename whose basename strips to empty (e.g. "x/" -- the trailing-slash shape), a distinct rejection branch from the tested "..", "up/..", and embedded-NUL cases. An empty client filename cannot reach it (empty filename means field part by construction), so the trailing slash is the only reachable shape. + *Recommendation:* Add a `part_spec{"a", "x/", nullptr, "data"}` case to sanitized_names asserting the typed invalid_argument rejection and an empty directory. + +28. [ ] **test-quality-reviewer** | `test/unit/forms_multipart_files_test.cpp:445` | logic-in-test + In keep_callback_once's true-keeps block, `dir.entries()[0]` is indexed immediately after a non-fatal `LT_CHECK(dir.entries().size() == 1)` with no guard: if the file was wrongly removed, littletest continues past the failed check and the index hits an empty vector (undefined behavior / garbage path) instead of producing a clean diagnostic. Every neighboring case in this file guards indexing with an `if (...size() == N)`. + *Recommendation:* Wrap the read_file comparison in `if (dir.entries().size() == 1) { ... }` to match the file's own convention. + +29. [ ] **test-quality-reviewer** | `test/unit/forms_multipart_test.cpp:112` | missing-test + Sink-failure propagation is exercised only through on_part_data: failing_sink (:112-135) fails every data callback, so the paths where a caller sink fails in on_part_begin or on_part_end (adopted as the decoder's sticky terminal via fail_with, then forwarded as the single on_part_abort by sink_event_adapter) are untested. The abort-once contract for those two terminals is unpinned even though the public header documents every callback's non-ok return as the decode's terminal. + *Recommendation:* Parameterize failing_sink over which callback fails (begin/data/end) and assert for each: the decode fails with the sink's outcome, on_part_abort fired exactly once (for begin/data) with that outcome carried, and zero aborts before any part began. + +30. [ ] **test-quality-reviewer** | `test/unit/multipart_decoder_test.cpp:464` | missing-test + Two implemented decoder behaviors have no tests: (a) obs-fold header continuations -- finalize_headers (src/httpserver/detail/forms_multipart.hpp:611-625) joins a line beginning with SP/HT onto the previous header's value and rejects a block that STARTS with a fold as typed invalid_argument; (b) first-wins for a duplicate per-part Content-Type (record_header, :653-660). disposition_shapes covers quoted filenames, case-insensitive parameter names, and duplicate Content-Disposition first-wins, but none of these adjacent parsing branches. + *Recommendation:* Add one part whose Content-Disposition value continues on an obs-fold line (decodes to the joined value) and one part whose header block begins with a fold (typed invalid_argument), plus a duplicate part Content-Type asserting the first value is carried. diff --git a/specs/unworked_review_issues/task-118_validation_16a92846d0b8acd99fcfbd4bd168e9df.md b/specs/unworked_review_issues/task-118_validation_16a92846d0b8acd99fcfbd4bd168e9df.md new file mode 100644 index 000000000..ec09b257e --- /dev/null +++ b/specs/unworked_review_issues/task-118_validation_16a92846d0b8acd99fcfbd4bd168e9df.md @@ -0,0 +1,181 @@ +# Unworked Review Issues + +**Run:** 2026-10-02 18:14:58 +**Task:** TASK-118 +**Total:** 43 (0 critical, 4 major, 39 minor) + +## Major + +1.

Count unchanged by the repair -- no 5th copy was added; the repair reshaped one of the four (rescue_exception now delegates to the helper) and left the other three inline. + *Recommendation:* Unchanged from iter-1: consolidate the remaining three inline consults through a small phase-templated consult helper (consult_exception_chain is now the natural seam); each site reduces to 2-4 lines and the 'invalid status is treated as pass' rule becomes single-sourced.

[ ] **code-simplifier** | `src/detail/request_lifecycle.cpp:188` | code-structure + Four near-identical hook-consult blocks: rescue_exception (lines 134-147), dispatch_method_miss (188-201), dispatch_hit (212-224) and short_circuit_request_received (232-244) each hand-roll the same sequence -- any_hooks gate, fire, is_pass check, take_response, status.valid() check, commit. The rule 'an invalid status is treated as pass' is enforced in four places but documented at only one (line 231), so a future change to that rule (or to the short-circuit semantics) must be replicated in four spots, and a divergence there would silently change one phase's contract. + *Recommendation:* Consolidate into one small template helper, e.g. template std::optional consult(const server::hook_bus& bus, Ctx& ctx) { if (!bus.any_hooks(P)) return std::nullopt; auto action = bus.fire

(ctx); if (action.is_pass()) return std::nullopt; auto page = std::move(action).take_response(); if (!page.status.valid()) return std::nullopt; return page; } -- each site then reduces to 2-4 lines (consult -> commit with its provenance) and the invalid-status rule is single-sourced.

[ ] **code-simplifier** | `test/unit/hooks_corpus_test.cpp:64` | code-structure + check_case (lines 64-128) and find_case (56-61) are wholesale copies of routing_corpus_test.cpp's check_case (67-130) / find_case (58-63); only the transcript filename, the ~10-line profile setup, and routing's head_only tracking differ. Most hazardous is the exactly-duplicated expectation-cursor walk (index/first/advances over found->expects, lines 110-126) -- nontrivial logic that must now be fixed in two files in sync. The shared driver test/parity/v3_dispatch_replay.hpp shares dispatch_once and the profile builders but stops short of the case-level loop, so plan D6's 'one replay driver' promise is only half met. (The src/-only PMD CPD gate exempts test/ by design, so this will never trip the gate.) + *Recommendation:* Hoist the case-level driver into v3_dispatch_replay.hpp as e.g. std::string replay_case(const char* transcript_path, const char* case_name, const replay_profile&, bool* head_only) taking a small profile struct {route_registry, hook_bus, error_page_factories}; each corpus test keeps only its profile construction and the per-case wrappers. DAMP still holds: the fixtures stay per-suite, only the dispatch/frame/parse/assert pipeline is shared. + +4. [ ] **code-simplifier** | `test/unit/hooks_corpus_test.cpp:64` | code-structure + [PRIOR iter-1 #2, carried forward, persists unworked -- non-blocking per coordinator] check_case/find_case remain wholesale copies of routing_corpus_test.cpp's driver; the exactly-duplicated expectation-cursor walk must still be fixed in two files in sync. Verified untouched by 9acbe21 (empty diff for hooks_corpus_test.cpp, routing_corpus_test.cpp, v3_dispatch_replay.hpp). + *Recommendation:* Unchanged from iter-1: hoist the case-level driver into test/parity/v3_dispatch_replay.hpp behind a small profile struct; each corpus test keeps only its profile construction and per-case wrappers. + +## Minor + +5. [ ] **architecture-alignment-checker** | `specs/architecture/v3/v2-parity-inventory.md:72` | pattern-violation + The Hooks migration note for the alias setters claims 'a throwing hook is caught, treated as pass(), and surfaced through the handler_exception chain', but the implementation swallows the exception inside hook_bus_impl::fire (src/detail/server_hooks.cpp:97-109, continue-as-pass) and surfaces it nowhere — hooks.hpp:68-72 and server_hooks.cpp:102-105 both defer the diagnostic surface as a milestone item, and request_lifecycle_test.cpp:512-548 confirms containment only. The inventory sentence overstates the shipped behavior (nothing routes a throwing HOOK into the handler_exception chain; that chain fires for handler throws). + *Recommendation:* Reword the migration note to match the implemented contract: a throwing hook is caught inside fire() and treated as pass(); no diagnostic surface exists yet (deferred milestone item). + +6. [ ] **architecture-alignment-checker** | `src/httpserver/server/hooks.hpp:170` | interface-contract + route_descriptor::pattern is documented as viewing 'the registry's stored pattern text' (valid while the registry is not mutated, i.e. until listen()-closed registration changes), but the dispatcher fills it from resolve_result::pattern_text (src/detail/request_lifecycle.cpp:65-71; field declared at src/httpserver/server/routes.hpp:434), which is a per-dispatch std::string copy owned by the dispatch_request coroutine frame. The view is valid only for the duration of the fire; a hook that stashes the pattern view (e.g. an access-log hook aggregating across requests) reads freed memory even though the documented contract says it stays valid. Note route_captures::name is unaffected (it views the registry entry's stored pattern text, satisfying the same wording in routes.hpp). + *Recommendation:* Either point describe() at the registry entry's stable stored pattern (e.g. have resolve_result carry a string_view into the registry entry, safe because registration is closed once listen() runs) or correct the hooks.hpp comment to state the view's lifetime is the request/dispatch only. + +7. [ ] **architecture-alignment-checker** | `src/httpserver/server/hooks.hpp:187` | interface-contract + PRIOR iter-1 finding 2 (minor) -- PERSISTS unworked; this is the carried-forward ledger item, not a new discovery (origin field used only in its 'pre-existing baseline defect unrelated to the repair' sense; causal_ref null per protocol). route_descriptor::pattern is still documented at hooks.hpp:187 as viewing 'the registry's stored pattern', but the dispatcher fills it from resolve_result::pattern_text (src/detail/request_lifecycle.cpp:75), a per-resolve std::string copy (declared src/httpserver/server/routes.hpp:461) owned by the dispatch_request frame; a hook stashing the view past the fire reads freed memory. Untouched by commit 9acbe21 (the routes.hpp changes concern admission-time segment storage, the tier early-exit, and the methods_observable parameter -- all properly documented in-place and behavior-neutral for non-hook-visible outcomes: the 405 Allow merge still carries the full tier either way). Does not meet the blocking threshold. + *Recommendation:* Either point describe() at the registry entry's stable stored pattern text (registration is closed once listen() runs) or correct the hooks.hpp comment to state the view's lifetime is the request/dispatch only. + +8. [ ] **code-quality-reviewer** | `src/httpserver/detail/exchange_runner.hpp:116` | dead-code + After the rewiring, no production code calls run_route - the connection engine dispatches through dispatch_request (src/detail/connection_engine_request.cpp:145) - so run_route survives only as a rig for existing test suites and the zero-hook byte-identity comparison (request_lifecycle_test.cpp:580-603). Its header comment still presents it as the general runner with no note that the engine no longer uses it, which invites future divergence between the two paths it was factored to keep identical (invoke_route_handler is the shared core). + *Recommendation:* Add one comment line on run_route marking it as the test-facing zero-hook baseline runner (or move it to a test-shared location if the project prefers), so its role and its required byte-identity with dispatch_request's zero-hook path stay discoverable. + +9. [ ] **code-quality-reviewer** | `src/httpserver/server/hooks.hpp:290` | api-contract + hook_handle's defaulted move constructor/assignment (lines 290-291) copy the scalar key_ without zeroing the source, so a moved-from handle still reports armed()==true, contradicting the documented contracts 'a moved-from handle is disarmed' (line 283) and 'False after remove(), detach(), or a move-out' (line 302). The failure mode is safe (the moved-from weak_ptr owner is empty, so the destructor's remove() is a no-op and no double-removal can occur), but armed() lies. There is no test for handle moves (server_hooks_test.cpp covers remove/detach/destructor only). + *Recommendation:* Define the move operations to reset the source's key_ to 0 (a two-line custom move ctor/assignment), or amend the two doc sentences; add a handle-move test asserting the moved-from handle is disarmed. + +10. [ ] **code-quality-reviewer** | `src/httpserver/server/routes.hpp:492` | test-coverage + The frozen baseline states the duplicate rule as 'same pattern with overlapping method -> invalid_state' without a family qualifier, but the implementation scopes it per family (known.prefix_ == prefix at line 492, documented in-code as the 'same-family duplicate check'), so the same pattern registered both as a full route and as a prefix route with fully overlapping methods is admitted. The interpretation is defensible (the two registrations serve different path shapes and compose sensibly), but no test pins it: server_routes_families_test.cpp never registers the same pattern in both families, so a later 'fix' toward the strict reading would silently change behavior with no failing test. + *Recommendation:* Add a server_routes_families_test case registering the same pattern as route() and route_prefix() with overlapping methods, asserting the intended outcome (coexistence, with the full tier owning the exact path), so the chosen reading of the baseline text is pinned. + +11. [ ] **code-quality-reviewer** | `test/unit/request_lifecycle_test.cpp:117` | code-smell + The trail helper's value_of (line 117) and count (line 129) members are never used by any test body - dead rig code left over from an earlier draft of the trail assertions. + *Recommendation:* Delete the two unused members, or use value_of where tests currently re-derive phase payloads by prefix matching. + +12. [ ] **code-quality-reviewer** | `test/unit/routing_corpus_test.cpp:58` | duplication + find_case and the entire expectation-cursor walk (parse transcript, dispatch requests, frame, feed response_frame_parser, normalize, advance the cursor across status/status_line expectations, check_expectation loop) are manually duplicated between routing_corpus_test.cpp:58-130 and hooks_corpus_test.cpp:56-128 - roughly 45 cloned lines per suite where only the registry/bus/pages setup differs. PMD CPD at 100 tokens does not flag it only because the interleaved setup differences break the token windows; it is still a manual clone. The plan's duplication-risk section explicitly called for the corpus suites to share one replay driver, and the dispatch half is shared (test/parity/v3_dispatch_replay.hpp) but the assertion half is not. + *Recommendation:* Hoist check_case's body into the shared driver (e.g. a replay::run_case(registry, bus, pages, transcript, case_name) taking the profile as inputs) so each corpus suite shrinks to case-name declarations plus its profile setup. + +13. [ ] **code-simplifier** | `src/detail/connection_engine_request.cpp:23` | comments + Stale comments still name run_route as the production dispatch path after this task switched the engine to dispatch_request: connection_engine_request.cpp:23 ('one sequential exchange through run_route'), src/httpserver/detail/connection_engine.hpp:36 ('route through run_route') and :425 ('decisions fire strictly later, inside run_route'), src/detail/connection_engine.cpp:593 ('its parked handler unwinds through run_route'), and test/integ/native_http1_e2e_test.cpp:161/:197 ('run_route synthesizes the 500' -- now the lifecycle dispatcher's run_handler/commit_bare). run_route itself is still the test-rig runner (route_sync, forms, exchange_routing suites), so only the comments mislead, not dead code. + *Recommendation:* Update the five comment sites to say 'the dispatch pipeline (dispatch_request)' / 'the lifecycle dispatcher'; they each describe the very seam this task changed, so an inaccurate name there sends the next maintainer to the wrong file. + +14. [ ] **code-simplifier** | `src/detail/connection_engine_request.cpp:23` | comments + [PRIOR iter-1 #5, carried forward] Stale run_route comments still misname the production dispatch path; re-verified present at connection_engine_request.cpp:23, connection_engine.cpp:597, connection_engine.hpp:36 and connection_engine.hpp:437. The repair edited two of these files (other hunks) without touching the stale names. + *Recommendation:* Unchanged from iter-1: update the four comment sites to name the dispatch pipeline (dispatch_request). + +15. [ ] **code-simplifier** | `src/httpserver/server/routes.hpp:224` | patterns + route_pattern::parse (lines 224-238) re-implements the slash walk that detail::split_path_segments (lines 128-143) already provides -- the same pos/find('/',pos)/width loop plus the same segment splitting, maintained twice in one file. + *Recommendation:* Let parse() call split_path_segments(text) and loop parse_route_segment over the returned segments (parsed.segments_ = segments.size()); the empty-segment and leading-slash semantics are identical (split_path_segments('' or '/') returns empty, matching the text != '/' guard).

[ ] **code-simplifier** | `src/httpserver/server/routes.hpp:61` | documentation + The plan (section 3 table: 'src/httpserver/detail/route_segments.hpp, private, ~170') and the frozen validation baseline both state the segment helpers moved to a private detail/route_segments.hpp. No such file exists: parse_route_segment, split_path_segments, match_segment_run, match_path_segments, match_prefix_segments, valid_parameter_name and is_name_byte (lines 61-194) remain inline in the public installed header, which the task added match_prefix_segments to. The deviation is sound and documented -- commit 6804279 explains that an installed public header cannot include a noinst detail header (the consumer-sentinel contract) and SLOC fits the gate without the move -- but that rationale lives only in the commit message; the plan record still asserts the move happened. + *Recommendation:* Record the accepted deviation where the next reader will look: a one-line note in the plan (or the task's migration notes) that the helper move to detail/route_segments.hpp was deliberately not done because routes.hpp is installed and detail headers are noinst.

The decision currently survives only in the untracked .groundwork-plans/TASK-118-plan.md (verified: `git ls-files .groundwork-plans/` is empty) — the exact pattern previously flagged as TASK-117 unworked-review issues #17/#18 (housekeeper, spec-not-updated). + *Recommendation:* Add one deferral clause — either to the hooks phases row (line 70) or the WebSocket table — stating that no v3 hook seat exists at the WebSocket upgrade point (upgrade admission belongs to the future v3 WebSocket engine tasks, TASK-121+), so the decision outlives the untracked plan file.

Relatedly, the frozen baseline's 'TASK-120 Allow/pages/prefix' is only half-met: the not_found row (line 68) carries 'TASK-120 consumes the mapping' while its method_not_allowed sibling (line 69) — the Allow half of the alias pair — omits the pointer. + *Recommendation:* Add one clause naming TASK-128 as the consumer of the deferred sanitizer-gated parity corpus runs (natural home: the routing row at line 50 or the pipelined row at line 55, next to the existing routing_corpus/native_http1_e2e citations), and mirror the 'TASK-120 consumes the mapping' pointer in the method_not_allowed row (line 69).

As with finding 2, the deferral lives only in the untracked plan file. + *Recommendation:* Append one clause to the alias-setters row (line 72), e.g. 'caught hook exceptions have no dedicated logging surface in v3 (the structured-diagnostics posture of the v3 architecture covers it); surfacing is the handler_exception chain alone'.

[ ] **performance-reviewer** | `src/httpserver/server/routes.hpp:546` | memory-allocation + resolve_tier declares a fresh std::vector per entry probe (line 546), and match_segment_run heap-allocates a std::string per parameter capture during probes that later fail on a deeper segment (routes.hpp:159-160). On parameterized-heavy registries (many /{tenant}/... shapes sharing prefixes) every probe allocates vector growth plus capture strings that are discarded. + *Recommendation:* Hoist one reusable scratch captures vector outside the entry loop (captures.clear() per entry, move out only on accept -- best_captures already demonstrates the pattern) so vector growth is amortized across probes; the per-capture strings remain bounded by parameter count on the accepted entry. + +28. [ ] **performance-reviewer** | `src/httpserver/server/routes.hpp:561` | memory-allocation + Every hit copies the matched pattern text into resolve_result::pattern_text (std::string copy, line 561). The registry's immutability while serving is already a documented invariant (routes.hpp:51-55, registration closed at listen) that capture names rely on via string_view, so the copy is avoidable; it is bounded (one allocation per hit), hence minor against the 'hit path allocations bounded' assumption. + *Recommendation:* Change resolve_result::pattern_text to std::string_view viewing best->pattern_.text() -- describe() (request_lifecycle.cpp:65-71) already converts it to the route_descriptor's string_view pattern, and no dispatch-path consumer needs ownership. + +29. [ ] **security-reviewer** | `src/httpserver/detail/lifecycle_sink.hpp:91` | observability-contract + lifecycle_sink::on_respond sets `responded_ = true` and calls fire_sent() unconditionally after forwarding to inner_.on_respond, but the engine sink can REFUSE the head: http1_exchange_sink::on_respond (src/detail/connection_engine_request.cpp:352-363) closes the connection without queueing when slot_->start() fails (framer refusal). The documented phase contract (server/hooks.hpp, plan D4/D5) is that response_sent fires "after the engine accepted the committed head ('queued')". On refusal, a response_sent hook -- the plan's stated mapping point for access logging -- records a response that never reached the wire, and the interceptor's responded() lies to any later query. No data leak or policy bypass; the committed head is genuinely not sent (request_close fires). + *Recommendation:* Make the acceptance verdict observable on the sink interface (e.g., http1_exchange_sink exposes an `accepted()` flag set only when slot_->start() succeeds), and gate `responded_ = true; status_ = ...; fire_sent();` in lifecycle_sink::on_respond on that verdict so response_sent only fires for heads the engine actually queued. + +30.

The adjacent surface already models the right rule: route_registry::route rejects an empty handler with typed invalid_argument ("route_registry: handler is empty"). + *Recommendation:* Reject an empty factory at the setter (typed invalid_argument, mirroring route_registry) and/or add a factories check to server_options::validate(), so the misconfiguration is caught at the pre-listen gate instead of crashing the worker on the first error page. + +31. [ ] **spec-alignment-checker** | `specs/architecture/v3/v2-parity-inventory.md:66` | specification-gap + The before_handler migration note says 'a hook may supply the 405 and the engine still appends Allow', framing the Allow append as v2-continuous. In v2 a short-circuiting before_handler was materialized verbatim (src/detail/request_dispatcher.cpp:290-293 returns directly to the materializer) and never received an engine-appended Allow — the append at src/detail/request_dispatcher.cpp:187-191 ran only on the default (no-hook) 405 path. v3's dispatch_method_miss (src/detail/request_lifecycle.cpp, append_allow call) does append Allow to a hook-supplied 405, a wire-observable delta in an unpinned scenario. The note does state the v3 behavior, so the REQ-038 record-the-change mechanism holds, but 'still appends' misdescribes v2 and the delta is not explicitly flagged. + *Recommendation:* Either reword the migration note to mark the Allow-on-hook-supplied-405 as an explicit v3 delta (e.g. 'the engine appends Allow to a hook-supplied 405 — v2 materialized the hook response verbatim on this path'), or align the dispatcher with v2 by not appending Allow when the before_handler hook supplies the 405.

In the corner where one hook of a phase supplies a valid response and another hook of the same phase throws, the implementation (short_circuit_request_received / dispatch_hit / dispatch_method_miss return before consult_exception_chain once the phase answered) performs no surfacing, so the inventory cell — the frozen parity contract baseline per this repo's convention — mildly over-claims. + *Recommendation:* Add the qualifier to the row's D4 clause, e.g. '...is surfaced through the handler_exception chain at the dispatcher when the phase itself did not answer the request', matching src/httpserver/server/hooks.hpp wording. + +33.

[ ] **code-quality-reviewer** | `src/httpserver/net/address.hpp:121` | robustness + address_pattern is a public aggregate whose prefix_bits is documented as 0..128, but matches() (net_address.cpp:227-242, declared noexcept) neither clamps nor asserts the range: a hand-constructed address_pattern{base, 200} makes the whole-byte loop (whole = prefix_bits/8 = 25) read past the 16-byte array — undefined behavior on a public-header value type with no compile-time guard. + *Recommendation:* Defend the documented range in matches() — either clamp whole to 16 / leftover accordingly, or assert(prefix_bits <= 128) as the hook_action take_response precedent does for its precondition; a comment stating the precondition alone leaves the noexcept surface UB-capable. + +2. [ ] **code-quality-reviewer** | `src/httpserver/net/address.hpp:133` | api-documentation + The public parse_pattern contract lists three rejection causes (other spelling, middle wildcard, prefix beyond the family's bit count) but not the fourth the implementation enforces: a v4-mapped IPv6 CIDR ("::ffff:10.0.0.0/104") is rejected because the literal normalizes to family ipv4 while a CIDR suffix demands ipv6 (net_address.cpp parse_v6:192). The asymmetry (mapped EXACT literal accepted, mapped CIDR rejected) is documented only in .cpp comments and in options.hpp's V12 gate comment — not on the public vocabulary header a consumer reads. + *Recommendation:* Add one sentence to the parse_pattern comment in net/address.hpp naming the mapped-CIDR rejection, so the public contract matches the two internal comments that already agree on it. + +3.

The accepted-verdict observation through the real listener (hook sees accepted=true with the peer snapshot at adopt_accepted) and plan D5's 'disabled policy still fires accept_decision accepted=true' promise are covered only at bus level (server_hooks fire_admission) and unit level (peer_policy disabled_admits_every_peer), never end-to-end through the accept loop. + *Recommendation:* Extend the e2e suite with one accepted-verdict accept_decision pin (register the hook, connect to an allow-listed server, assert fired=1/accepted=true/peer text) — optionally in the same test with set_enabled(false) to pin the D5 disabled-still-observes rule. + +4. [ ] **code-simplifier** | `src/detail/net_address.cpp:146` | dead-code + In parse_v4_wildcard the middle-wildcard rejection (line 146, 'Reject any further wildcard inside the surviving segments') runs after parse_address(literal + ".0"): inet_pton only accepts digits and dots, so any '*' in literal already failed the parse on line 142-143 and the guard can never fire. A reader puzzles over why the delta guard is placed after the check it guards. + *Recommendation:* Move the literal.find('*') test before the parse_address call (fail fast, and the guard becomes live documentation of the middle-wildcard delta), or delete it as unreachable. Behavior is identical either way. + +5. [ ] **code-simplifier** | `src/detail/net_address.cpp:165` | dead-code + parse_v4's family re-check (lines 164-165, base->family != address_family::ipv4) is unreachable: parse_v4 is only reached from parse_pattern with a colon-free text, and parse_address's colon-free branch returns ipv4 or nullopt. Unlike the analogous check in parse_v6 (line 192), which is load-bearing for mapped CIDR, this one can never fire. + *Recommendation:* Drop the family half of the condition and keep the has_value() test, or, if it is kept as a symmetry guard against future grammar drift in the parse_pattern dispatch, say so in a one-line comment so the next reader does not hunt for a reachable path. + +6. [ ] **code-simplifier** | `src/detail/peer_policy.cpp:112` | duplication + drop() (lines 112-120) repeats add()'s parse-failure block (lines 94-102) verbatim, including the identical multi-line message string 'peer_policy: pattern ... is not an address, trailing-wildcard, or CIDR spelling'. The next message edit must be made twice. + *Recommendation:* Extract a file-local helper, e.g. std::optional parse_pattern_or_fail(std::string_view text, http::outcome& out) (or a helper returning the failure outcome for an unparseable text), and call it from both add() and drop(). + +7.

Verified via git show HEAD to pre-date the repair: the mis-attached comment already sat on fill_peer before the fix; the repair inserted fill_peer's own correct comment below it, which clarifies the immediate ambiguity but leaves accept_one without an adjacent doc block. Pre-existing defect in the original reviewed baseline, unrelated to the repair's semantic change. + *Recommendation:* One-move cleanup in a later pass: relocate the accept_one doc comment (lines 369-375) to sit directly above the accept_one definition at line 407, leaving fill_peer with its own comment.

The header-resident placement is documented and necessary (server_options must compile without the library; listen() converts residual divergence into a typed failure), so this is a cleared fence -- but the two implementations must be edited in lockstep, and only the options.hpp side cross-references its twin. net_address.cpp never mentions that options.hpp re-encodes its grammar. + *Recommendation:* At minimum add the back-reference comment in src/detail/net_address.cpp (near parse_pattern) naming options.hpp's V12 validators as the twin that must stay in sync.

[ ] **housekeeper** | `src/httpserver/server/options.hpp:143` | documentation-stale + The committed contract comment on `peer_policy_options` says runtime mutation 'goes through native_server::peer_policy() (thread-safe, DR-V3-008)', but DR-V3-008 is 'Split handler-safe stop initiation from drain completion' (specs/architecture/v3/architecture.md §6, line 243) — a stop/drain decision that says nothing about peer-policy mutation. The thread-safety contract being carried is v2's DR-008 'Thread-safety contract' (specs/architecture/11-decisions/DR-008.md; the TASK-119 plan §1 cites 'runtime-mutable, thread-safe from handlers (DR-008)' for v2 deny_ip/allow_ip). The citation conflates v2 DR-008 with v3 DR-V3-008, the record whose context explicitly says it 'directly reverse[s] v2 DR-008's stop-in-handler deadlock contract' (architecture.md:247). + *Recommendation:* Correct the decision-record citation in the options.hpp comment to the record that actually carries the thread-safety contract (v2 DR-008, or the peer_policy.hpp class contract itself if that is the intended v3 anchor). One-token fix in the same commit that resolves finding 1. + +11. [ ] **performance-reviewer** | `src/detail/peer_policy.cpp:174` | algorithmic-complexity + An armed classify() is a linear scan over both pattern vectors (matches_locked) per accept and again per request at the dispatch head, so per-request cost is O(total pattern count). The prefix-collapse invariant merges covering entries but disjoint entries (e.g. a blocklist of thousands of distinct /32s) accumulate without bound. For typical ACL sizes (tens to low hundreds) the contiguous 20-byte POD scan beats v2's pointer-chasing std::set::count, but at blocklist scale (10k+ disjoint patterns) it adds tens of microseconds per request per list. + *Recommendation:* Acceptable as shipped for v2-parity workloads. Document a soft expectation on pattern count in peer_policy.hpp, or if large-list support becomes a requirement, keep each list sorted by prefix_bits and binary-search the candidate prefix (or move to a compact radix trie). No change needed for this milestone. + +12. [ ] **performance-reviewer** | `src/detail/peer_policy.cpp:80` | memory-allocation + insert_aware() rebuilds the entire destination vector (fresh kept vector with reserve, then swap) on every non-covered insert, so seeding an n-pattern policy from server options at listen() is O(n^2) pattern copies plus one heap allocation per insert under the writer lock. A blocklist-scale seed (10k entries) costs ~50M pattern copies at listen time. Config-time only; no steady-state cost. + *Recommendation:* Fine for the milestone. If large seeded policies become a use case, add a bulk-seed path (sort + single prefix-collapse merge pass) to native_server::impl::listen instead of calling deny()/allow() per entry. + +13. [ ] **performance-reviewer** | `test/Makefile.am:1020` | missing-caching + The plan D5 zero-cost-when-unarmed contract and the plan risk section's 'no measurable accept cost expected' acceptance for the io_result widening are not pinned by any benchmark: the existing bench_targets cover hook overhead, route lookup and the warm path, but nothing measures accept-path or classify() cost in either armed or unarmed state. + *Recommendation:* Add a bench (bench_warm_path.cpp style) that pins (a) unarmed dispatch parity with a null-policy run and (b) armed classify with a small list, so a future regression of the armed gate cannot land silently. Release-gated via make bench, not per-commit CI, per the existing bench policy. + +14. [ ] **security-reviewer** | `src/detail/net_address.cpp:93` | input-validation + zcopy() copies the raw bytes including any embedded NUL and lets inet_pton stop at the first NUL, so a std::string_view containing '\0' parses to a different pattern than its visible spelling: allow("0.0.0.0\0/0") splits at the '/', parses the literal as 0.0.0.0 via NUL truncation, and yields prefix_bits 96 (0.0.0.0/0, matches every IPv4 peer) -- a match-all widening under reject_all. The options path is safe (V12's valid_ipv4/valid_ipv6 reject NUL), and the runtime deny/allow surface is application-trusted per the frozen baseline, so this is hardening rather than an exploitable path (CWE-1284/CWE-20). + *Recommendation:* Reject text containing '\0' in zcopy() (or in parse_address/parse_pattern before any parsing) so the parsed value can never differ from the caller-visible spelling. + +15. [ ] **security-reviewer** | `src/httpserver/server/options.hpp:503` | security-misconfiguration + valid_peer_pattern()'s mapped-CIDR exclusion compares literal.substr(0,7) == "::ffff:" case-sensitively, while the store parses hex case-insensitively via inet_pton and rejects any mapped base with a CIDR suffix (parse_v6 requires family ipv6 when a suffix exists). So "::FFFF:1.2.3.4/96" passes validate() (V12) but fails listen() seeding with a typed invalid_argument -- fail-closed, no bypass, but a grammar split between the gate and the store that contradicts the header's 'SAME grammar' contract and turns a configuration the API accepted into a listen-time failure. + *Recommendation:* Make the prefix comparison case-insensitive (e.g. ascii_iequals over the 7 chars, or normalize to lowercase first), or drive V12 through the store's own parse judgment for the mapped-CIDR case. + +16. [ ] **spec-alignment-checker** | `src/httpserver/server/options.hpp:242` | ears-requirement + V12 grammar split against the live store's parser (PRD-V3N-REQ-016). detail::valid_ipv6 accepts a compressed literal whose explicit groups total 8 (rule is head+tail <= 8), e.g. "1:2:3:4:5:6:7:8::" or "::1:2:3:4:5:6:7:8", but the store's parse path (detail/net_address.cpp -> OS inet_pton) rejects those spellings (compression must stand for at least one group, explicit <= 7). Direction: validate() returns ok for such a deny/allow entry while listen() then fails typed during seeding (src/detail/server.cpp returns the seeding failure). The failure is still pre-accept and typed, so REQ-016's letter holds and the options.hpp comment ("listen() turns any residual divergence ... into a typed failure") documents the fallback, but the two grammars disagree on an edge spelling instead of being the SAME grammar the comment promises. The reverse split also exists on this platform: macOS inet_pton accepts zone-indexed v6 ("fe80::1%eth0") and leading-zero v4 ("192.0.02.1") that valid_peer_pattern rejects, so runtime native_server::peer_policy().deny() accepts spellings the options gate refuses (conservative direction; no listen-time failure). + *Recommendation:* Tighten valid_ipv6: when a "::" is present require head + tail <= 7 (0-group degenerate "::" still passes); optionally add a V12 test pinning the 8-explicit-group-with-compression spellings as invalid, and decide one stance on zone-index/leading-zero spellings across both surfaces. + +17. [ ] **spec-alignment-checker** | `src/httpserver/server/peer_policy.hpp:24` | specification-gap + Wrong decision-record citation for the threading contract. The header comment (and the matching comments in src/httpserver/server/server.hpp, src/httpserver/server/options.hpp, and src/detail/server.cpp) justifies "runtime-mutable from any thread including inside handlers (DR-V3-008)" by DR-V3-008, but the architecture register (specs/architecture/v3/architecture.md) defines DR-V3-008 as "Split handler-safe stop initiation from drain completion" -- a stop/drain decision that says nothing about handler-thread mutation of policy state. The v2 decision that carried that contract was DR-008 (thread-safety from handlers), which v3 supersedes only for stop(). The task's related decision DR-V3-001 (semantic vocabulary, no engine/backend types) is correctly cited elsewhere (net/address.hpp, hooks.hpp). + *Recommendation:* Correct the comments to cite the actual authority for handler-thread-safe mutation (v2 DR-008 carried forward for non-stop APIs, or a named v3 threading decision), or record the contract under a dedicated v3 decision; do not leave DR-V3-008 attached to a claim it does not make. + +18. [ ] **spec-alignment-checker** | `test/integ/native_http1_e2e_test.cpp:2611` | acceptance-criteria + The engine-path coverage for accept_decision only pins the refusal side. Plan D5 states "disabled -> trivially accept but accept_decision still fires accepted=true", and D6 fires the phase on every accepted transport, but the only engine-driven test (native_http1_e2e accept_decision_observes_refusal, test 31) registers the hook against a denied peer; the accepted=true firing through the real listener (including the unarmed/default-policy server and the peer snapshot the context carries for admitted connections) is exercised only by manual bus firing in server_hooks_test (fire_admission(bus, true, none)). No assertion anywhere proves an admitted transport fires the phase exactly once from adopt_accepted. + *Recommendation:* Extend one existing admitted-path e2e (e.g. allow_listed_loopback_serves or any default-policy hooks test) to register an accept_decision hook and assert fired==1, accepted==true, reason==none, peer=="127.0.0.1". + +19.

It is exercised only indirectly -- the dispatch gate classifies x.peer() (request_lifecycle.cpp:396), and the allowed/refused twin pair proves the snapshot is carried -- but the user-facing read path (a handler observing the client address) would fail silently (e.g. returning a default-constructed peer) without a failing test. + *Recommendation:* One assertion in the existing allowed_peer_runs_pipeline test: have the /hello handler (or a request_received hook via the exchange it cannot see -- so the handler) copy x.peer().to_string() out and LT_CHECK it equals '127.0.0.1:41000', pinning port and address visibility to user code. + +20.

Do NOT free the underlying buffer data before the -// MHD_Response is destroyed. -// -// ALLOCATION NOTE: -// std::vector unconditionally heap-allocates its backing store, so every -// iovec_response_body construction performs one heap allocation.

Main class of the apis. - * - * ### Threading contract - * - * The webserver dispatches each request on one of libmicrohttpd's worker - * threads. The thread-safety contract: - * - * 1. Public registration / un-registration methods (@ref register_path, - * @ref register_prefix, the @ref on_get - * family, @ref route, @ref unregister_path, @ref unregister_prefix, - * @ref unregister_resource, @ref register_ws_resource, - * @ref unregister_ws_resource, @ref deny_ip, @ref remove_denied_ip, - * @ref allow_ip, @ref remove_allowed_ip) are - * thread-safe and re-entrant from inside a request handler. - * The route lookup LRU cache (`detail::route_lru_cache`) is consulted - * outside `route_table_mutex_`, so an in-flight request that hit the - * cache may still be served by a resource whose @ref unregister_path / - * @ref unregister_resource call already completed concurrently. No - * use-after-free results -- the cache holds a `shared_ptr` that keeps - * the resource alive -- but the response for that one request may be - * logically stale (served by the just-unregistered handler). - * 2. The exceptions are @ref stop, @ref stop_and_wait, and the - * destructor: each joins libmicrohttpd's worker threads and - * therefore deadlocks (or aborts with "Failed to join a thread." - * on some libmicrohttpd versions) when called from within a - * handler thread. Call them from the thread that owns the - * webserver instance. - * 3. `http_request` is single-threaded per request: it is owned by - * the worker thread servicing that request and MUST NOT be - * retained beyond the handler's return. - * 4. `http_response` is a value type with exclusive ownership; no - * cross-thread sharing. - * 5. User-supplied callbacks invoked from MHD worker threads -- - * @ref create_webserver::log_access, @ref create_webserver::log_error, - * @ref create_webserver::not_found_handler, - * @ref create_webserver::method_not_allowed_handler, - * @ref create_webserver::internal_error_handler, - * @ref create_webserver::file_cleanup_callback, the PSK / SNI / ALPN - * callbacks, any registered @ref http_resource render method, and - * any registered lifecycle hook (@ref add_hook / @ref http_resource::add_hook ) - * -- may run concurrently on multiple threads. Implementations MUST be thread-safe. - * - * ### Handler error-propagation contract - * - * Every registered request handler is invoked from the dispatch path under - * a two-branch try/catch. The contract: - * - * 1. The handler call is wrapped in - * `try { ... } catch (const std::exception& e) { ... } catch (...) { ... }`. - * 2. On `std::exception`: the message is logged via the configured - * `log_error` callback, then `internal_error_handler` is invoked with - * `e.what()`. The response it returns is sent on the wire. When no - * handler is configured, the default 500 carries the fixed body - * `"Internal Server Error"` (CWE-209 fix); - * the originating message is still surfaced via the - * `log_error` callback. The verbose v1 body (message in the body) - * is opt-in via @ref create_webserver::expose_exception_messages. - * 3. On non-`std::exception` (e.g. `throw 42`): same path with the - * message replaced by the literal string `"unknown exception"`. - * 4. If `internal_error_handler` itself throws while servicing 2 or 3, - * the failure is logged generically and a hardcoded 500 with an - * EMPTY body is sent. No exception ever escapes into libmicrohttpd. - * 5. `feature_unavailable` (a `std::runtime_error` subclass) is NOT - * mapped to a special status: it lands as a generic 500 like any - * other `std::exception`. - * 6. The `log_error` callback may be invoked concurrently from multiple - * MHD worker threads; user implementations MUST be thread-safe. - * 7. Hook layering: - * @ref hook_phase::handler_exception hooks fire BEFORE this alias; - * throwing hooks are caught and the chain continues; (4) fires - * without re-invoking the alias on full chain failure. - * - * Resources are encouraged to throw rather than synthesise 500s. -**/ -class webserver { - public: - // Explicit to forbid implicit conversion from - // create_webserver.

wire error codes. The payload column lists routed +stream IDs; `/` identifies stream 1 and `/sibling` identifies stream 3. +The stage `eof` requires EOF during a field block. `unadvertised` withholds +server SETTINGS exposure to exercise RFC 8441 capability gating. + +Executor schedules are semantic boundaries, independent of input fragmentation: + +- `feed` defers executor work until the entire transcript has been parsed. +- `pump` runs pending work and retires output after each completed frame. +- `dispatch` runs pending work after each completed frame, suspends the stream 1 + handler on an application signal, and defers output retirement until input is + parsed. The later stream error cancels this suspended handler. This schedule + applies to `content-length-data`, `malformed-trailer`, `closed-data`, + `stream-window-overflow` and `half-closed-head`. + +Binary HPACK literals are authored independently of the library encoder. The +harness checks resets, GOAWAY, response order, sticky failure, consumption, +routes and complete budget release. Coalesced, bytewise, every split and partial +output retirement must give identical wire output within a fixed schedule. +The five later-error fixtures retain their original route 1 observation and +exact stream error verdicts. Paired deferred-start regressions require zero +stream 1 calls: a reset invalidates queued lazy work before execution. Started +application waits must be destroyed once without running after a late signal; +started body reads may complete once with typed `connection_closed`. A separate +token observer must complete once with typed `cancelled`. All reservations must +return after teardown. These rules follow PRD-V3N-REQ-023/025, DR-V3-003/006 and +the queued-handler cancellation contract in `docs/task-142-http2-evidence.md`. + +Dispatching an immediately completed response is a different schedule: an +END_STREAM opening becomes fully closed before later input. The harness checks +`closed-data` and `half-closed-head` separately in that schedule for connection +STREAM_CLOSED, rather than treating its result as interchangeable with the +original half-closed stream verdict. Changing only input chunk boundaries never +selects a different schedule. + +The paired tests append an independently authored dynamic-table insertion in a +discarded HEADERS block on reset stream 1, then stream 3 references index 62. +They assert the sibling's actual `x-route: after` field, exact route order, +reset-before-response ordering, full suffix consumption, no duplicate reset or +GOAWAY, admission/cancellation counts and all fragmentation variants. Per-case +and aggregate corpus/schedule execution counts are printed in the test log. + +RFC 9113 sections 5.3.2, 6.2, 6.3 and Appendix B deprecate priority dependency +semantics. Self-dependency therefore has no error verdict. PRIORITY length, +nonzero stream placement and continuation isolation remain enforced. + +Required minimum/final HPACK table updates after acknowledged SETTINGS changes +are covered by `hpack_corpus` using independent octets; peer SETTINGS affects the +response encoder, so feeding those settings to this engine cannot emulate local +receive-table changes. The existing 28 connection-level fixtures remain separate. + +The TLS fixture exercises the real private request engine. The public listener +still dispatches HTTP/1.

client magic. The shared corpus loader reads +five TSV columns: name, RFC sections, feed/EOF stage, verdict, expected output +hexadecimal octets. Verdict is `scope wire-code consumed-offset output-mode`; +scope is `ok`, `stream`, or `connection`. `drain` consumes output after each +completed input event; `hold` preserves output to exercise the two-slot queue. +The initial server SETTINGS is consumed before client input. EOF is applied +when all bytes have been consumed. Every fixture runs coalesced, bytewise and +at every split. Stream errors consume the entire offending frame and allow +later framing; connection errors consume no subsequent suffix. Expected output +includes the initial SETTINGS, ACKs and at most one terminal GOAWAY. A stream +owner would use the typed stream error to send RST_STREAM. + +These prove private framing and control behavior. Request dispatch, stream +state, HPACK block collection, multiplexing and flow control are later tasks. diff --git a/test/conformance/http2/ack-payload.wire b/test/conformance/http2/ack-payload.wire

Fuzzing uses a writable build-local copy of this corpus. diff --git a/test/data/quic/callbacks/all-levels-suites.seed b/test/data/quic/callbacks/all-levels-suites.seed new file mode 100644 index 000000000..f1dd492fb Binary files /dev/null and b/test/data/quic/callbacks/all-levels-suites.seed differ diff --git a/test/data/quic/callbacks/backpressure.seed b/test/data/quic/callbacks/backpressure.seed new file mode 100644 index 000000000..99a6dbe60 Binary files /dev/null and b/test/data/quic/callbacks/backpressure.seed differ diff --git a/test/data/quic/callbacks/budget-dispatch-secret.seed b/test/data/quic/callbacks/budget-dispatch-secret.seed new file mode 100644 index 000000000..fdefd48a8 Binary files /dev/null and b/test/data/quic/callbacks/budget-dispatch-secret.seed differ diff --git a/test/data/quic/callbacks/chacha-transitions.seed b/test/data/quic/callbacks/chacha-transitions.seed new file mode 100644 index 000000000..faff0c407 Binary files /dev/null and b/test/data/quic/callbacks/chacha-transitions.seed differ diff --git a/test/data/quic/callbacks/close-held-lease.seed b/test/data/quic/callbacks/close-held-lease.seed new file mode 100644 index 000000000..62b18a5b6 Binary files /dev/null and b/test/data/quic/callbacks/close-held-lease.seed differ diff --git a/test/data/quic/callbacks/failure-pending-close.seed b/test/data/quic/callbacks/failure-pending-close.seed new file mode 100644 index 000000000..06d4fc546 Binary files /dev/null and b/test/data/quic/callbacks/failure-pending-close.seed differ diff --git a/test/data/quic/callbacks/invalid-release.seed b/test/data/quic/callbacks/invalid-release.seed new file mode 100644 index 000000000..d78755f75 Binary files /dev/null and b/test/data/quic/callbacks/invalid-release.seed differ diff --git a/test/data/quic/callbacks/lease-transition.seed b/test/data/quic/callbacks/lease-transition.seed new file mode 100644 index 000000000..687ef5db3 Binary files /dev/null and b/test/data/quic/callbacks/lease-transition.seed differ diff --git a/test/data/quic/callbacks/params-repetition.seed b/test/data/quic/callbacks/params-repetition.seed new file mode 100644 index 000000000..ef602cb27 Binary files /dev/null and b/test/data/quic/callbacks/params-repetition.seed differ diff --git a/test/data/quic/parser/README.md b/test/data/quic/parser/README.md new file mode 100644 index 000000000..ade6611fe --- /dev/null +++ b/test/data/quic/parser/README.md @@ -0,0 +1,20 @@ +# QUIC parser seeds + +Each `.seed` is a raw byte input, including an empty input.

TASK-138 adds complete sections and connection-owned +tables. `hpack_corpus` checks all RFC 7541 Appendix C.2-C.6 blocks against fixed +ordered fields and table snapshots, with independent request/response sequence +contexts and the response examples' negotiated 256-byte capacity. It also runs +8,192 seeded primitive/section mutations (`0x7541137`) and per-octet section tag +mutations and truncations. + +`hpack_fuzz_input` accepts at most 512 bytes. The first eight bytes control +prefix width, integer value/octet limits, payload/decoded limits, output limit, +and integer high bits. Outputs are capped at 64 bytes; invalid controls are +intentional. The remaining bytes are borrowed wire input. The entry checks +bounds, absence of committed failed output, determinism, input preservation, +and encode/decode round trips, including trailing string input. + +The additional section exercise borrows at most 64 wire bytes, processes two +consecutive blocks with one connection owner, and seeds a prior dynamic entry. +Each directional table is capped at 128 bytes and shares a 256-byte hierarchical +budget. Compressed output is capped at 64 bytes, expanded occurrences at 128 +bytes, and field count at four. The second block uses input-derived smaller +limits. Assertions check sticky terminal failure, unpublished failed outputs, +expanded accounting, table bounds, and retained reservation bounds. An +independent decoder (at most 128 additional retained table bytes) replays each +successful encoder output in order and checks fields and never-indexed policy. + +With a Clang installation containing libFuzzer, build from the source root: + +```sh +clang++ -std=c++20 -O1 -g -fsanitize=fuzzer,address,undefined \ + -fno-omit-frame-pointer -DHTTPSERVER_COMPILATION -DHPACK_LIBFUZZER \ + -Isrc -Itest test/fuzz/hpack_fuzz.cpp -o build/hpack_fuzzer +mkdir -p build/hpack-fuzz-corpus +build/hpack_fuzzer build/hpack-fuzz-corpus -max_total_time=30 \ + -timeout=2 -max_len=512 -rss_limit_mb=512 -seed=7541137 +build/hpack_fuzzer build/hpack-fuzz-corpus -runs=0 -max_len=512 +``` + +Apple Clang may lack `libclang_rt.fuzzer_osx.a`; Homebrew LLVM's `clang++` +provides the local libFuzzer runtime. ASan/UBSan are executed in this smoke +run. An empty corpus is supported. To seed published examples, prepend eight +control bytes (for example `05 ff ff 0b 40 40 40 00`) to the hex-decoded +fixture blocks. Add integer zero chains, overflowing continuations, huge +lengths with missing data, truncated literals, EOS/padding errors, high-bit +bytes, and expanded-budget edges. The deterministic check includes these +families; production decoders receive them directly in the unit tests. + +`hpack_primitives` also observes real `operator new` calls: large malformed, +expanded-over-limit, encoded-over-limit, truncated, and encoder-over-limit +inputs request zero output allocations. Valid 4 KiB decoded output requests +one string allocation after admission (standard string capacity may round up). +`hpack_connection` observes aggregate raw/Huffman section refusal and table +reservation refusal before input-sized octet copies, without assuming successful +allocation counts or a standard-library capacity growth policy. + +Keep any minimized finding as a deterministic regression before resuming fuzzing. +BSD, Windows, and other nonlocal platform evidence belongs to CI and the v3 PR. diff --git a/test/fuzz/hpack_fuzz.cpp b/test/fuzz/hpack_fuzz.cpp new file mode 100644 index 000000000..d76abcc1c --- /dev/null +++ b/test/fuzz/hpack_fuzz.cpp @@ -0,0 +1,167 @@ +/* + This file is part of libhttpserver + Copyright (C) 2011-2026 Sebastiano Merlino + + This library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + This library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

+// - parsing: case-insensitive scheme, SP/HTAB separators, strict +// token68/base64, first-colon split, colon-less token keeping an +// empty password, empty user; +// - matching: fixed credentials through the constant-time +// comparison, equal-length wrong-user and wrong-password +// classifying identically with byte-identical challenges; +// - the validator form: decoded pair delivered, empty rejected; +// - factory validation: CR/LF/NUL realms refused with out +// untouched, backslash/quote escaping, empty realm legal; +// - credential redaction: no challenge or diagnostic string the +// API produces ever contains the fixed credentials or the +// client's token; +// - the guard adapter: unauthenticated requests answer 401 without +// invoking the wrapped handler; authenticated ones flow through. + +#include +#include +#include +#include +#include + +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include + +#include "./littletest.hpp" + +using httpserver::auth::basic_auth_policy;

Driven through +// detail::run_route with the scripted fakes (the route_sync +// convention); the members live in the library, so the suite links +// libhttpserver.la (default LDADD).

+// - the decoder-level caps: a body one byte past max_total_bytes +// and one part past max_parts both answer 413 with the explicit +// Content-Length: 0 framing and the handler never runs (the +// distinct branch from the gate path's drain-level 413, driven in +// the type-gate test: one 413 with BARE fields -- no explicit +// Content-Length -- zero handler invocations, zero writer +// traffic); +// - a malformed multipart body answers 400 with the length-framed +// empty body; +// - the v2 content-type gate: a non-multipart type (value end, +// ';'/whitespace boundary, suffix-extended, case differences) +// still drains under the cap and reaches the handler with EMPTY +// fields; a matching type WITHOUT a boundary parameter answers +// 400 (the strictness delta); +// - a bodyless POST reaches the handler with empty fields; +// - a segmented body source decodes identically to a one-shot feed; +// - a disconnect mid-body fires on_part_abort exactly once (the +// streaming read), commits nothing, and removes the temp-file +// sink's partial file; +// - read_multipart after a manual admit_body answers invalid_state;
