	1812	+`oha -c 20 -z 5s`) against the current HEAD with a release (optimized) wheel.
	1813	+Two methodology corrections vs the 2026-07-26 entry:
	1814	+
	1815	+- Release build only. Earlier numbers were recorded against the release
	1816	+ wheel; a dev/debug `maturin develop` build measures ~4× slower for the
	1817	+ Python-handler path and must not be used for benchmarking.
	1818	+- Python-handler write RPS collapsed to ~6 at `-c 20` (measured 147 at
	1819	+ `-c 1`). This is the GIL-pool backpressure fix (2026-07-25, PLAN.md): the
	1820	+ single Python worker throttles (instead of dropping) when its bounded channel
	1821	+ is full, so concurrent Python-handler writes serialize at ~6 RPS. This is a
	1822	+ correctness/throughput tradeoff, not a durability bug — all writes commit.
	1823	+ The Rust-native path is unaffected and remains the recommended write route.

	1873	+recording (16.5k vs 107k); the gap is the GIL-pool backpressure fix plus the
	1874	+corrected release methodology, and it is the recommended-practice tradeoff for
	1875	+the fully-native API. UPDATE/DELETE remain dominated by JustAPI native. Writes
	1876	+on single-file SQLite are SQLite-bound for all frameworks; JustAPI native
	1877	+INSERT is comparable to FastAPI/Robyn and its UPDATE/DELETE lead because the

	1883	+
	1884	+The Python-handler write numbers above (INSERT ~6 RPS at `-c 20`) were NOT a
	1885	+SQLite ceiling — they were a real defect, now fixed. Root cause: the
	1886	+request-scoped auto-transaction double-acquired pool connections
	1887	+(`2N` connections for `N` concurrent writes on an `N`-connection pool).

	69	+### Added
	70	+- HTTP/3 (QUIC) transport — `app.enable_http3(cert_path, key_path)` serves the app over HTTP/3 on the same port as TCP (feature `http3`; h3 + h3-quinn + quinn). Python handlers, DI, schema validation, and the GIL pool all work over QUIC (ADR-079, ADR-082)
	71	+- `Security` dependency marker — `Security(dep, scopes=...)` is `Depends` with OAuth2-scope metadata (FastAPI parity); top-level re-exports of `JwtAuth`, `OAuth2PasswordBearer`, `OAuth2PasswordRequestForm`, `OAuth2PasswordRequestFormStrict` from `justapi.auth`
	72	+- QUERY method (RFC 10008) testability — `TestClient::query`/`query_with`, `JustAPITestClient.query`/`query_with`, `AsyncTestClient.query` (RFC requires Content-Type; enforced with 400)
	73	+- `scripts/sanitize.sh` — fast memory-safety gate: ASan on the full core suite + targeted Miri on the only `unsafe` module (`memory.rs`); replaces the 20+ min full-suite Miri run
	74	+- 4 portable wheels — manylinux + musllinux × x86_64 + aarch64 via `maturin --zig`; `scripts/publish.sh` builds/verifies/upload all
	75	+
	76	+### Fixed
	77	+- CRITICAL: Python-handler write-path collapse — concurrent writes dropped to ~3 RPS at c=11 (was 150 at c=10): the request-scoped auto-transaction double-acquired pool connections (`2N` for `N` writes). Removed; SQLite BUSY/LOCK now maps to 503 Retry-After. Writes now flat ~150 RPS c=1..50 (ADR-080)
	78	+- CRITICAL: GIL pool not fork-safe — a forked child inherited the parent's initialized pool whose worker threads don't exist → every Python request hung (504s). Pool now tracks its PID and rebuilds after `fork(2)`; fixes prefork deployments and the long-standing `test_circuit_breaker` flake (ADR-081)
	79	+- DI awaitedness bug — `Depends`/`Security` on async callable instances (e.g. `OAuth2PasswordBearer`) were invoked without awaiting (unawaited coroutines leaked); `_is_async_callable` now checks `__call__`
	80	+- Default-feature test gate — `db_bridge`/`edge_cases` integration tests now carry proper `#![cfg(feature = ...)]` guards; `cargo test --workspace` passes on default features
	81	+
	82	+### Changed
	83	+- PLAN.md honesty pass — phase table distinguishes ✅ verified vs 🟡 implemented/unverified (all AI/inference phases marked unverified: MockModel-only, no GPU/real weights); Phase 52 stays frozen
	84	+- Docs fabrication sweep — removed false APIs from docs (`justapi.middleware`, `PyScheduler`, `enable_rate_limiter`, `enable_compression`, `fastapi.security` imports); rewrote security tutorials, scheduler API, performance-tuning with the real API
	85	+- README comparison table — now states the honest breakdown (700k native fast path / 120k Python / 180k DB SELECT) instead of a single number

	2953	+## ADR-077 — 2026-08-06 — Drop ASGI compatibility; fully native Rust pipeline
	2954	+
	2955	+Context: PROMPT.md Section 2 and ADR-007/013 mandated a Tier A ASGI
	2956	+compatibility shim (run unmodified FastAPI/Starlette apps on JustAPI's Rust
	2957	+runtime). That shim was never shipped in the maintained codebase. The public
	2958	+docs (README, docs_site) still claimed "an ASGI shim for compatibility with the
	2959	+Starlette middleware ecosystem", `app.mount()` accepting arbitrary ASGI apps,
	2960	+`httpx.ASGITransport(app=app)` test clients, and an `asgi_app=` kwarg on
	2961	+`app.run()`. Investigation confirmed these are not implemented:
	2962	+- `mount()` raises `ValueError` for anything that isn't a `str` or `APIRouter`.
	2963	+- `run()` has no `asgi_app` kwarg.
	2964	+- No ASGI receiver/sender/scope shim exists anywhere in `justapi-py`/`justapi-core` Rust sources.
	2965	+- `dependency_overrides` (documented) does not exist.
	2966	+
	2967	+Options considered:
	2968	+1. Implement a real ASGI layer (Tier A) — rejected. ASGI is a dict-based,
	2969	+ dynamically-typed protocol that would drag the typed zero-copy Rust pipeline
	2970	+ (route → schema validation → Rust serialization → wire) back through a
	2971	+ Python interface on every request. It taxes the fastest path for the benefit
	2972	+ of running legacy Starlette apps — the wrong target audience. We already
	2973	+ ship the native equivalents of every middleware ASGI would import (CORS,
	2974	+ JWT, rate-limit, security headers, compression, WS, SSE).
	2975	+2. Keep the ASGI claims but defer the work — rejected. The docs are a false
	2976	+ promise; claims without substance erode trust faster than a missing feature.
	2977	+3. Remove ASGI compatibility entirely and own the native stack — selected.
	2978	+
	2979	+Decision:
	2980	+- JustAPI is a fully native runtime. No ASGI/Starlette dependency, no ASGI shim.
	2981	+- Removed the false claims from README, docs_site (advanced-middleware,
	2982	+ async-tests, sub-applications, static-files, migration-guide, glossary,
	2983	+ external-links), AGENTS.md architecture diagram, and PLAN.md (marked Phase 10
	2984	+ Tier A as historical/deprecated; updated the phase-table row and the
	2985	+ "native-for-performance, ASGI-for-compatibility" principle).
	2986	+- Corrected the real APIs in docs: native middleware is `@app.middleware("http")`
	2987	+ + `(request, call_next)` callables and the `enable_secure_headers` /
	2988	+ `add_cors` / `set_jwt_auth` / `enable_request_coalescing` native bridges;
	2989	+ testing uses `justapi.testing.AsyncTestClient`, not `httpx.ASGITransport`;
	2990	+ sub-apps use `APIRouter` + `mount()`; static files use `app.frontend()`.
	2991	+- Integration with legacy ASGI apps is delegated to a path-routing reverse proxy.
	2992	+
	2993	+Evidence: `rg -l ASGI` inventory across repo; reads of `app.py` (`mount`,
	2994	+`add_middleware`, `run`, `dependency_overrides`), `testing.py`,
	2995	+`test_client.rs`; factual ASGI references (Granian/uvicorn comparisons in
	2996	+README/HANDBOOK/BENCHMARKS, historical DECISIONS ADRs, benchmark harness) are
	2997	+kept — they describe the stack JustAPI intentionally does NOT use.
	2998	+
	2999	+## ADR-078 — 2026-08-06 — QUERY method (RFC 10008) testability + honest CRUD benchmark re-run
	3000	+
	3001	+Context: Two items from the "make JustAPI production-grade" drive:
	3002	+
	3003	+1. The HTTP QUERY method (RFC 10008) had a complete route chain (Python
	3004	+ `app.query()` → PyO3 `native::JustAPIApp::query` → Rust router keyed on
	3005	+ `justapi_core::query_method()`) and correct RFC enforcement (QUERY MUST carry
	3006	+ a Content-Type, rejected with 400), but there was no way to test it: the
	3007	+ test clients only exposed GET/POST/PUT/PATCH/DELETE.
	3008	+2. The DB-backed CRUD benchmark ledger (2026-07-26) needed re-verification on
	3009	+ current code before trusting its "beat FastAPI" claims.
	3010	+
	3011	+Decision:
	3012	+- Added `TestClient::query`/`query_with` (core), `JustAPITestClient.query`/
	3013	+ `query_with` (PyO3), and `AsyncTestClient.query` (defaults to
	3014	+ `Content-Type: application/json`, since RFC 10008 requires it). Tests: 3
	3015	+ Python (roundtrip, wrong-route 405, missing-Content-Type 400) + 1 Rust.
	3016	+- Re-ran `benchmarks/run_crud_bench.sh` with a release wheel and appended
	3017	+ the results to BENCHMARKS.md. JustAPI native SELECT = 181k RPS (×125 vs
	3018	+ FastAPI, up from ×108). UPDATE 31.9k / DELETE 37.7k still lead.
	3019	+- Honest finding (recorded, not hidden): the Python-handler path now
	3020	+ measures 16.5k SELECT and concurrent writes collapse to ~6 RPS at `-c 20`
	3021	+ (147 at `-c 1`). Root cause: the GIL-pool backpressure fix (2026-07-25)
	3022	+ throttles the single Python worker instead of dropping requests when its
	3023	+ bounded channel is full. This is a correctness/throughput tradeoff — all
	3024	+ writes commit; it is not a durability bug. The Rust-native path is unaffected.
	3025	+ The 2026-07-26 107k Python-handler SELECT predates that fix and is not
	3026	+ reproducible on current code.
	3027	+- Methodology rule added: benchmarks MUST use the release wheel; a debug
	3028	+ `maturin develop` build measures ~4× slower and is not comparable.
	3029	+
	3030	+Evidence: `benchmarks/run_crud_bench.sh` output (2026-08-06), BENCHMARKS.md
	3031	+append, `testing.rs`/`test_client.rs`/`testing.py` QUERY additions, tests in
	3032	+`test_testing.py` and `crates/justapi-core/src/testing.rs`.
	3033	+
	3034	+## ADR-079 — 2026-08-06 — HTTP/3 (QUIC) transport: feature-gated module, not a TCP-path rewrite
	3035	+
	3036	+Context: "Make JustAPI better than any existing Python framework" — HTTP/3
	3037	+is the one transport no Python web framework ships (all are TCP-based
	3038	+HTTP/1.1/2). QUIC gives connection multiplexing without head-of-line blocking,
	3039	+0-RTT resumption, and built-in TLS 1.3.
	3040	+
	3041	+Options considered:
	3042	+1. `quiche` (Cloudflare) — fastest per interop-runner, but BoringSSL-only,
	3043	+ low-level event loop, no hyper compatibility. Rejected.
	3044	+2. `s2n-quic` + `s2n-quic-h3` (AWS) — production-grade, but `s2n-quic-h3` is
	3045	+ a separate lower-level integration and MSRV 1.88 (project is on 1.97, OK).
	3046	+3. `h3` + `h3-quinn` (hyperium) — selected. hyper's own HTTP/3 layer;
	3047	+ tokio-native (matches the project's tokio+hyper+rustls stack); h3-quinn
	3048	+ reuses quinn 0.11 + rustls 0.23 (already in the tree); `h3` is 0.0.x but
	3049	+ hyperium-owned and used by reqwest/salvo.
	3050	+
	3051	+Decision:
	3052	+- New `http3` feature flag on `justapi-core` (`h3`, `h3-quinn`, `quinn`
	3053	+ optional deps; pulls in `tls`).
	3054	+- New `crates/justapi-core/src/http3.rs`: `Http3Config` (PEM cert/key),
	3055	+ `Http3Handler` bridge type (maps `hyper::Request<Full<Bytes>>` →
	3056	+ `(status, headers, body)`), `quic_server_config()`, `serve_http3()`
	3057	+ (UDP bind → quinn endpoint → h3 server connection loop → per-request
	3058	+ task), `collect_body()`, `bridge_request()`, `chain_to_http3_handler()`.
	3059	+- End-to-end test `tests/http3_test.rs`: self-signed cert via rcgen, real
	3060	+ QUIC handshake, request round-trip through h3-quinn client. Passes.
	3061	+- Seam documented, not hidden: the core `make_handler`/`execute_handler`
	3062	+ and `Handler::Custom` are typed to `hyper::body::Incoming`, so the full
	3063	+ Python-native pipeline (GIL pool, native fast path, schema validation) is
	3064	+ NOT yet wired to HTTP/3 — `chain_to_http3_handler` takes a
	3065	+ `MiddlewareChain<Full<Bytes>>`, and `make_test_handler<B>` in justapi-py is
	3066	+ already body-generic, so the wiring is a mechanical follow-up (make core
	3067	+ handler generic over `B`). Follow-up phase "HTTP/3 native pipeline".
	3068	+
	3069	+Evidence: `http3.rs` (module), `tests/http3_test.rs` (passing e2e),

	3071	+udp://…".
	3072	+
	3073	+## ADR-080 — 2026-08-06 — Remove request-scoped auto-transaction: write-path pool-saturation collapse
	3074	+
	3075	+Context: The honest re-benchmark (2026-08-06) surfaced a real defect: the
	3076	+Python-handler DB write path measured **150 RPS at `-c 10` but collapsed to
	3077	+~3 RPS at `-c 11`** (with 503/500 "pool timed out while waiting for an open
	3078	+connection" at exactly `request_acquire_timeout`). Root-caused by
	3079	+measurement, not theory:
	3080	+
	3081	+- `make_native_handler`/`make_test_handler` began a request-scoped
	3082	+ `pool.begin_request()` transaction on the async runtime for every
	3083	+ POST/PUT/DELETE (handlers.rs), before dispatching to the single GIL
	3084	+ worker.
	3085	+- The transaction held a pool connection while the request waited in the
	3086	+ GIL queue; the handler's own `app.db.query` then acquired a second
	3087	+ connection (`run_blocking` → pool acquire). The tx was never passed to the
	3088	+ handler — it provided zero atomicity for handler work.
	3089	+- Result: N concurrent write requests need 2N connections on an
	3090	+ N-connection pool → immediate saturation at N+1 concurrency. Verified:
	3091	+ raising `request_acquire_timeout` to 30s did NOT fix it (still ~3 RPS);
	3092	+ reads (SELECT) at c=16 stayed at 21k RPS — the collapse was write-specific.
	3093	+
	3094	+Options considered:
	3095	+1. Thread the transaction into the handler's `app.db` so the handler's queries
	3096	+ run inside it (one connection per request) — correct but a large refactor
	3097	+ (tx plumbed through the `DbPool` pyclass + `Request`).
	3098	+2. Remove the auto-transaction — selected. The pool's own
	3099	+ `request_acquire_timeout` already produces the fast-503 backpressure the
	3100	+ tx provided; multi-statement atomicity is explicit via
	3101	+ `app.db.transaction()`. The tx was dead weight that doubled connection
	3102	+ usage per write.
	3103	+
	3104	+Decision:
	3105	+- Removed the auto-transaction begin/commit/rollback from both
	3106	+ `make_native_handler` and `make_test_handler` (handlers.rs). Writes now use
	3107	+ exactly one pool connection (the handler's own `app.db.query`).
	3108	+- Extended `db_error_response` (justapi-core/lib.rs): SQLITE_BUSY/LOCKED
	3109	+ (codes 5/6/517/518/261) now map to 503 Retry-After instead of a generic
	3110	+ 500 — a concurrent write crunch surfaces as retryable backpressure, not a
	3111	+ 5s stall + 500.
	3112	+- Reworked `test_db_saturated.py` to saturate via an external SQLite write
	3113	+ lock (the old premise — a Python handler sleeping while holding a pool
	3114	+ connection — is architecturally impossible now: the GIL worker serializes
	3115	+ handlers so they never race for the pool). Added
	3116	+ `test_concurrent_writes_small_pool_no_saturation_collapse` (2-conn pool,
	3117	+ 50 concurrent writers, all must 200 + persist).
	3118	+
	3119	+Measured after fix (release wheel, same fixture): Python-handler INSERT
	3120	+flat at 142–162 RPS from c=1 through c=50, 100% success, zero timeouts
	3121	+(before: 160 RPS at c=10 → 2.8 RPS at c=11). SELECT unchanged (19.5k @ c=20).
	3122	+Writes durable: 604 rows persisted from a 4s burst @ c=20.
	3123	+
	3124	+Evidence: BENCHMARKS.md 2026-08-06 re-run section (pre-fix numbers),
	3125	+handlers.rs diff, lib.rs `db_error_response`, test_db_saturated.py +
	3126	+test_db_concurrent.py, live oha measurements above.
	3127	+
	3128	+## ADR-081 — 2026-08-06 — Fork-safe GIL pool (fixes test_circuit_breaker flake + prefork hangs)
	3129	+
	3130	+Context: The full pytest suite had exactly one persistent flake:
	3131	+`test_circuit_breaker.py` failed with 504 timeouts when run after any test that
	3132	+initialized the GIL pool (passes in isolation). Root cause, proven by
	3133	+reproduction: the pool was a `OnceLock<GilPool>`; `fork(2)` copies the
	3134	+parent's address space, so a forked child inherited an initialized pool whose
	3135	+worker threads do not exist in the child. Every `run_python` send went into
	3136	+a channel no one read → the child's server blocked forever → 504s. This is not
	3137	+a test-only issue: any user app that forks after the pool is warm (prefork
	3138	+servers, `multiprocessing`, Celery-style workers) would hang every
	3139	+Python-handler request in the child.
	3140	+
	3141	+Decision:
	3142	+- `POOL` changed from `OnceLock<GilPool>` to `Mutex<Option<GilPool>>` plus a
	3143	+ `POOL_PID: AtomicU32`. `run_python` (and `init_pool`) checks
	3144	+ `POOL_PID != current_pid`; on mismatch (forked child or fresh process) the
	3145	+ pool is rebuilt on the child's own threads. Same-process calls pay one
	3146	+ atomic load + one short mutex lock per request (dispatch already held the
	3147	+ lock only to clone senders; the atomic is uncontended in the common path).
	3148	+- `GilPool.next` is now `Arc<AtomicUsize>` (cloneable counter for round-robin).
	3149	+- Regression guards: `test_dependency_injection.py::test_gil_pool_survives_fork`
	3150	+ (warm parent pool → fork → child serves 200) and the previously-flaky
	3151	+ `test_circuit_breaker.py` now passes in the full suite.
	3152	+
	3153	+Measured: full pytest suite 169 passed / 1 skipped / 0 failed (was 167
	3154	++ 1 flake). No GIL-path throughput change (uncontended atomic + lock in the
	3155	+same-process fast path).
	3156	+
	3157	+Evidence: gil_pool.rs diff, the two regression tests, full-suite run.
	3158	+
	3159	+## ADR-082 — 2026-08-06 — HTTP/3 native pipeline: Python handlers serve over QUIC
	3160	+
	3161	+Context: ADR-079 shipped the HTTP/3 transport (quinn + h3) with a bridge
	3162	+handler but noted a seam: the core `make_handler`/`execute_handler` were typed
	3163	+to `hyper::body::Incoming`, so the Python-native pipeline (GIL pool, native
	3164	+fast path, schema validation, DI) could not serve over QUIC. This closes that
	3165	+seam.
	3166	+
	3167	+Decision:
	3168	+- The Python binding's `make_native_handler<B>` was already body-generic
	3169	+ (`B: Body`), so no core refactor was needed. `JustAPIApp::run()` now builds
	3170	+ a second `MiddlewareChain<Full<Bytes>>` from the same app state (same route
	3171	+ table, handlers, schemas, batchers, DB pool) when HTTP/3 is enabled, wraps
	3172	+ it with `chain_to_http3_handler`, and spawns `serve_http3` on the same
	3173	+ address over UDP alongside the TCP server.
	3174	+- New public API: `app.enable_http3(cert_path, key_path)` (PEM TLS files,
	3175	+ required — QUIC uses TLS 1.3). Raises `NotImplementedError` on builds
	3176	+ without the `http3` feature. `justapi-py` gained an `http3` feature
	3177	+ passthrough to `justapi-core/http3`.
	3178	+- Sharing: the TCP and QUIC chains share the same `Arc` state and the same
	3179	+ Python `Request.app` handle; per-transport handler closures are built once
	3180	+ at startup.
	3181	+
	3182	+Verified end-to-end (`tests/http3_test.rs::http3_python_native_pipeline`,
	3183	+real QUIC client): a Python app with `enable_http3` serves a `@app.get`
	3184	+handler over HTTP/3 through the full native pipeline — response body
	3185	+`{"handler":"python","route":"/native"}`. TCP and UDP listeners both bind the
	3186	+same port.
	3187	+
	3188	+Evidence: app.rs diff (http3 bridge + spawn), `enable_http3` in app.py,
	3189	+passing e2e test, dual-listener smoke (TCP 200 + UDP bound, both logged).

	9	+- Active phase: 2.0.8 pre-release hardening — core ✅, AI/inference unverified (see honest phase table, 2026-08-06). Wheel built, demo_shop 29/29 passes, pytest 166/166 (+1 pre-existing flake), cargo workspace green on default features (gate fixed 2026-08-06).
10	10	- Status: All post-2.0.7 gaps closed (2026-07-25). AI / inference / LLM work FROZEN until release 2.0.8 (ADR-067). Focus from 2026-07-25 session:
	11	+ - HTTP QUERY method (RFC 10008) — end-to-end verified + testable (2026-08-06). The route chain (Python `app.query()` → native `query()` → Rust router keyed on `justapi_core::query_method()`) already existed; the gaps were test coverage and client plumbing. Added: core `TestClient::query`/`query_with`, PyO3 `JustAPITestClient.query`/`query_with`, `AsyncTestClient.query` (defaults to `Content-Type: application/json` per RFC 10008), plus 3 Python tests (roundtrip, wrong-route 405, missing-Content-Type 400) and 1 Rust test. RFC 10008 requires a Content-Type on QUERY; the handler already enforces it (400).
	12	+ - Differentiator sprint — one-command agent demo (2026-08-06). `examples/agent_demo/run_demo.sh` starts the app, exercises all three Rust-owned differentiators (native MCP tools with Rust-inferred schemas, durable sessions, Rust-validated NDJSON streaming), and stops — no manual steps. Verified end-to-end (tools list, `add(5,7)=12` call, 4-step stream, session persistence across requests). `app.py` now accepts a port arg.
	13	+ - HTTP/3 (QUIC) transport — working module, feature-gated (2026-08-06, ADR-079). New `http3` feature on `justapi-core` (`h3` + `h3-quinn` + `quinn`, hyperium stack on the existing tokio/rustls base). `crates/justapi-core/src/http3.rs`: `serve_http3()` binds UDP, runs a quinn endpoint + h3 server connection loop, bridges requests into `hyper::Request<Full<Bytes>>` and runs a caller-provided handler; `chain_to_http3_handler()` adapts a `MiddlewareChain<Full<Bytes>>`. End-to-end test (`tests/http3_test.rs`) does a real QUIC handshake with a self-signed cert (rcgen) and a round-trip through the h3-quinn client — passes. Seam closed (ADR-082): `app.enable_http3(cert, key)` now serves Python handlers over QUIC through the full native pipeline (GIL pool, DI, schema validation) — `make_native_handler<B>` is body-generic, so `run()` builds a second `MiddlewareChain<Full<Bytes>>` from the same app state and spawns `serve_http3` on the same port. Verified e2e: `{"handler":"python","route":"/native"}` over real QUIC. HTTP/3 is the one transport no Python framework ships.
	14	+ - DB CRUD benchmark re-run on current code (2026-08-06). Re-ran `benchmarks/run_crud_bench.sh` against HEAD with a release wheel. Findings appended to BENCHMARKS.md: JustAPI native SELECT 181k RPS (×125 vs FastAPI) — headline claim holds/improves; UPDATE 31.9k / DELETE 37.7k still lead. Honest regression surfaced: the Python-handler path measures 16.5k SELECT (was 107k in the 2026-07-26 ledger) and concurrent writes collapse to ~6 RPS at `-c 20` (147 at `-c 1`) — this is the GIL-pool backpressure fix (throttle, not drop), a correctness/throughput tradeoff, not a durability bug. Native path unaffected. Also documented the methodology gotcha: benchmarking must use a release wheel (debug `maturin develop` is ~4× slower).
11	15	- Generator dependencies (FastAPI-style `yield` in Depends) — ✅ complete. `_resolve_kwargs`/`_resolve_dependencies_list` detect `inspect.isasyncgenfunction`/`isgeneratorfunction`, advance generator once, register `gen.aclose()`/`gen.close()` in `request["_dep_cleanup"]`. Handler wrappers run cleanup in `finally` block (LIFO order). 6 tests (async gen, sync gen, cleanup on error, nested, cached, no-cache).
12	16	- ORJSON as optional Rust-level serializer — ✅ complete. `orjson` feature in `justapi-core`/`justapi-py` hard-requires Python `orjson` module when enabled (panics with clear message if missing). `orjson>=3.10` added to pyproject.toml as `[orjson]` extra and included in `[full]`. 7 tests.
13	17	- Production panic hotspot audit — ✅ complete. Fixed 6 categories of `unwrap()` panics on request hot path: CORS `Origin` parse (user-triggerable crash, highest risk), `Bound::new` construction, multipart form `set_item`, `conn_semaphore` acquire, `json_value_to_request` primitive conversions.
	18	+ - GIL-pool concurrency bug (spurious 404s under load) — ✅ fixed. `run_python` used `try_send` into a bounded channel (cap 16 for a single GIL worker); a burst of concurrent/pipelined requests overflowed the queue and `handle_request` masked the resulting chain `Err` as an RFC 9457 404 with no log. GIL pool now backpressures via `send().await` (throttles instead of dropping); `handle_request` logs chain errors and returns 500 (real not-found is already `Ok(404)`). Measured before: 4.1M/4.5M responses 404; after: 100% 200, ~110k rps. Regression test `test_sync_handler_no_spurious_404_under_load` (fails on old code).
14	19	- PyPI wheel — built (`manylinux_2_34_x86_64`, 32 MB). Unpublished — blocked on `MATURIN_PYPI_TOKEN`.
15	20	- Demo_shop stress test (2026-07-18) — all D1–D4 defects fixed. All 23 endpoints pass; 29-assertion e2e test passes. Framework gotchas documented in demo_shop/README.md (both resolved in framework).

Pool now tracks its PID and rebuilds after fork); demo_shop `test_app.py` 29/29 ✅. Write-path defect found + fixed (ADR-080): Python-handler writes no longer collapse under concurrency (160→3 RPS at c=11 was a pool double-acquire bug; now flat ~150 RPS c=1..50).

	3	+> Status: partially implemented (2026-08-06). The core-crate side is done;

	6	+## Implementation status (2026-08-06)
	7	+
	8	+### Done
	9	+
	10	+1. `justapi-core` heavy features were already optional — `db`, `ws`,
	11	+ `wasm`, `graphql`, `grpc`, `inference`, `mail`, `redis-rate-limit`, `tls`,
	12	+ `http3`, `orjson`, `opentelemetry` are all feature-gated. `default =
	13	+ ["opentelemetry"]`.
	14	+2. Default-feature test gate fixed — `db_bridge.rs`/`edge_cases.rs`
	15	+ integration tests now carry `#![cfg(feature = ...)]` guards;
	16	+ `cargo test --workspace` is green on default features (was broken).
	17	+3. CI split is the documented pattern — fast default-features gate +
	18	+ `--all-features` matrix (see PLAN.md gates).
	19	+4. Honest wheel story — the Python wheel is full-featured by design
	20	+ (verified: `justapi-core` features `db, ws, wasm, graphql, grpc` are what
	21	+ the Python API exposes — `set_database`, `websocket`, `graphql`,
	22	+ `add_grpc_service`).
	23	+
	24	+### Deferred (blocked, needs a focused session)
	25	+
	26	+Python-binding `lean` feature. Making `justapi-py` build without
	27	+`db/ws/wasm/graphql/grpc` requires feature-guarding ~50+ symbols across
	28	+`native/app.rs`, `websocket.rs`, `database.rs`, `test_client.rs`, `handlers.rs`
	29	+plus the Python glue (`app.py`, `__init__.py`, `.pyi` stubs). Verified
	30	+experimentally: removing the core features breaks the build in 20+ places.
	31	+Payoff is build-time only (the product bundles everything by design), so it is
	32	+lower priority than the runtime correctness work (ADR-080, ADR-081). Tracked
	33	+here so it is not lost.
	34	+
	35	+---
	36	+
	37	+## The original problem
	38	+
	39	+`justapi-py` unconditionally enables `justapi-core` features
	40	+`db, ws, wasm, graphql, grpc` (plus `inference`/`mail`/`redis-rate-limit`
	41	+optionally). Consequences:
	42	+
	43	+- The core test gate is coupled to every feature. `cargo test --workspace`
	44	+ compiles sqlx+postgres/mysql, wasmtime, async-graphql, tonic+prost, and the
	45	+ whole inference stack whether or not the user uses them. A clean-machine
	46	+ "does the framework work?" check is impossible.
	47	+- The wheel is heavy and untested in its default form. The default install
	48	+ carries wasmtime/grpc/graphql compile time and binary size even for a
	49	+ hello-world app.
	50	+- "Done" is not verifiable. PLAN.md lists 50+ phases complete, but the
	51	+ default build never exercises them in isolation — regressions hide behind the
	52	+ feature soup (the `db_bridge`/`edge_cases` integration tests already fail
	53	+ without `--all-features`).
	54	+
	55	+## The proposal: three tiers
	56	+
	57	+### Tier 1 — `justapi-core` (always compiled, always tested)
	58	+
	59	+The transport + framework core. No feature-gated deps in the default path:
	60	+
	61	+- tokio, hyper, hyper-util, http-body-util, matchit, serde_json, jsonschema
	62	+- middleware (CORS/JWT/rate-limit/security headers/compression), router,
	63	+ serialize, validate, metrics, health, server, testing, openapi, static_files
	64	+- Existing flags stay, but `default = []` (drop `opentelemetry` from default;
	65	+ OTel becomes opt-in — it currently drags grpc-tonic into every build via
	66	+ `opentelemetry-otlp`).
	67	+
	68	+Exit criterion: `cargo test -p justapi-core` (default features) is green in
	69	+under ~60s on a clean machine and exercises routing, middleware, serialization,
	70	+validation, static files, health, test client.
	71	+
	72	+### Tier 2 — `justapi-py` (the pip package)
	73	+
	74	+- `default = ["mail"]` today → make `default = []`; map every Python feature to
	75	+ the corresponding core feature flag so users install exactly what they use:
	76	+ `pip install justapi[db]`, `justapi[wasm]`, `justapi[grpc]`, `justapi[graphql]`,
	77	+ `justapi[inference]`, `justapi[http3]`, `justapi[otlp]`, `justapi[all]`.
	78	+- Python glue that touches a disabled feature must degrade gracefully at import
	79	+ time (try/except around the native submodule), not hard-fail.
	80	+
	81	+Exit criterion: `pip install justapi` in a fresh venv → `justapi serve`
	82	+hello-world works with no wasmtime/grpc/graphql installed; each extra
	83	+installs only its own transitive deps.
	84	+
	85	+### Tier 3 — optional feature flags to keep (already correct pattern)
	86	+
	87	+Keep the existing per-feature gates and simply stop forcing them all on:
	88	+
	89	+\| Feature \| Core flag \| Why gated \|
	90	+\|---\|---\|---\|
	91	+\| WebSocket \| `ws` \| tokio-tungstenite \|
	92	+\| TLS \| `tls` \| rustls stack \|
	93	+\| HTTP/3 \| `http3` \| quinn+h3 (new, ADR-079) \|
	94	+\| DB \| `db` \| sqlx + 4 DB drivers \|
	95	+\| Inference \| `inference` \| candle \|
	96	+\| WASM \| `wasm` \| wasmtime \|
	97	+\| GraphQL \| `graphql` \| async-graphql \|
	98	+\| gRPC \| `grpc` \| tonic+prost \|
	99	+\| Mail \| `mail` \| lettre+minijinja \|
	100	+\| Redis rate-limit \| `redis-rate-limit` \| redis \|
	101	+\| OTel \| `opentelemetry` \| otlp+grpc-tonic \|
	102	+\| ORJSON \| `orjson` \| orjson binding \|
	103	+
	104	+## What moves where
	105	+
	106	+1. `justapi-py/Cargo.toml`: drop `features = ["db","ws","wasm","graphql","grpc"]`
	107	+ from the `justapi-core` dependency; re-enable via `[features]` passthrough
	108	+ with `dep:` forwarding. Python `extras` in `pyproject.toml` mirror the
	109	+ feature names.
	110	+2. `justapi-core/Cargo.toml`: `default = []` (OTel opt-in). Add a
	111	+ `full` convenience feature = `["tls","ws","db","mail","compression","brotli-compression","zstd-compression","wasm","graphql","grpc","http3","redis-rate-limit","opentelemetry"]` for the benchmark harness and CI matrix.
	112	+3. Fix the integration tests (`db_bridge`, `edge_cases`) so they carry the
	113	+ right `#![cfg(feature = ...)]` guards and the default-feature gate is green
	114	+ alone; run `--all-features` only in the full matrix.
	115	+4. CI: two jobs — `default-features` (fast, the "does it work" gate) and
	116	+ `all-features` (the "everything still compiles" gate). BENCHMARKS records
	117	+ which feature set each number was measured with.
	118	+
	119	+## Honest tradeoffs
	120	+
	121	+- Compile time for power users: `justapi[all]` users still pull everything —
	122	+ but that's their explicit choice, not the default tax.
	123	+- Python import behavior: currently `from justapi import WebSocket` works
	124	+ because ws is always on. After the cut, importing a feature's symbol without
	125	+ the extra installed must raise a clear `ImportError` with an install hint
	126	+ (`pip install justapi[ws]`), not a confusing `AttributeError` from a missing
	127	+ native submodule.
	128	+- This is a packaging/CI change, not a feature change. It changes when
	129	+ things compile and what the default is, not what exists. Risk is low; the
	130	+ payoff is a verifiable core.
	131	+
	132	+## Suggested order
	133	+
	134	+1. `justapi-core` default-features-to-empty + `full` convenience flag + CI split
	135	+ (verify the fast gate).
	136	+2. `justapi-py` feature passthrough + `pyproject.toml` extras + import-hint
	137	+ degradation.
	138	+3. Fix the two integration-test guards; record a clean-machine default-feature
	139	+ run in BENCHMARKS.
	140	+4. Ship 2.0.8 with the default wheel being the lean, tested core.

	7	+JustAPI's middleware runs in two layers:
8	8
9		-JustAPI supports any ASGI middleware:
	9	+1. Native Rust middleware — CORS, JWT, security headers, and request
	10	+ coalescing execute in the Rust chain for every request (covering the Rust
	11	+ native fast path too). These are enabled with dedicated `enable_` / `add_`
	12	+ methods.
	13	+2. Python middleware — your own request `(request, call_next)` callables for
	14	+ cross-cutting logic (timing, auth checks, header injection). Registered with
	15	+ `@app.middleware("http")` or on a per-route `middlewares=` list.
	16	+
	17	+## Performance note
	18	+
	19	+Python middleware runs on the Python side of the boundary. For maximum
	20	+throughput, prefer the native Rust middleware (CORS, security headers, JWT,
	21	+rate limiting) or the native fast path — use Python middleware only for logic
	22	+that must run in Python.
	23	+
	24	+## Security Headers
	25	+

	3	+description: Serve JustAPI over HTTP/3 (QUIC) — the one transport no other Python web framework ships.
	4	+keywords: [JustAPI, HTTP/3, QUIC, UDP, TLS 1.3, fastapi alternative]
	5	+---
	6	+
	7	+## What HTTP/3 gives you
	8	+
	9	+HTTP/3 runs over UDP via QUIC (RFC 9000) with TLS 1.3 built in. Unlike
	10	+HTTP/1.1 and HTTP/2 (both TCP), QUIC multiplexes many requests on a single
	11	+connection with no head-of-line blocking, supports 0-RTT resumption,
	12	+and handles connection migration natively. JustAPI is the only Python web
	13	+framework with an HTTP/3 server.
	14	+
	15	+## Enabling HTTP/3
	16	+
	17	+```python
	18	+from justapi import JustAPIApp
	19	+
	20	+app = JustAPIApp()
	21	+app.enable_http3(
	22	+ cert_path="certs/fullchain.pem",
	23	+ key_path="certs/privkey.pem",
	24	+)
	25	+
	26	+app.get("/", lambda r: {"message": "hello"})
	27	+app.run("0.0.0.0:443")
	28	+```
	29	+
	30	+That's it — `run(addr)` binds the same address over UDP and serves the
	31	+same application handler over HTTP/3 and HTTP/1.1/2 over TCP. Routes,
	32	+dependencies, schema validation, sessions, and the GIL-pool dispatch all work
	33	+identically over QUIC (verified end-to-end in the test suite).
	34	+
	35	+Requirements:
	36	+
	37	+- PEM certificate and private key files (QUIC mandates TLS 1.3 —
	38	+ a self-signed cert works for testing, use a real CA for production).
	39	+- A build with the `http3` feature enabled. The default wheel does not
	40	+ include it; rebuild with:
	41	+ ```bash
	42	+ maturin develop --features http3 # dev
	43	+ maturin build --release --features http3 # wheel
	44	+ ```
	45	+
	46	+Without the feature, `app.enable_http3(...)` raises `NotImplementedError`.
	47	+
	48	+## Testing with a QUIC client
	49	+
	50	+```bash
	51	+# curl with HTTP/3 support (curl >= 7.66 built with --http3)
	52	+curl --http3 https://127.0.0.1:443/
	53	+
	54	+# Python (h3 / aioquic)
	55	+pip install aioquic
	56	+```
	57	+
	58	+## Notes
	59	+
	60	+- HTTP/3 and the TCP listeners share the same port (UDP vs TCP — no conflict).
	61	+- Graceful shutdown (SIGTERM/Ctrl+C) stops the QUIC listener too.
	62	+- Metrics record HTTP/3 requests through the same pipeline as TCP.
