	1643	+## Real DB-backed CRUD benchmark — JustAPI vs FastAPI vs Robyn (recorded 2026-07-20)
	1644	+
	1645	+This is the "real life" benchmark the production audit (PRODUCTION_PLAN.md P2.1)
	1646	+called for: single-row INSERT / SELECT / UPDATE / DELETE through a SQLite file
	1647	+(WAL, `busy_timeout=5000`, 10-connection pool) under `oha -c 10 -z 5s`, on the
	1648	+same hardware fixture (i5-13600K, 20 threads, CachyOS). Each framework runs a
	1649	+plain Python handler that issues one SQL statement per request:
	1650	+
	1651	+- JustAPI (Python-handler): handler calls `app.db.query(sql, params)`.
	1652	+- JustAPI (Rust-native): `app.post("/items", crud_table=..., crud_columns=...)`
	1653	+ — op inferred from HTTP method, served entirely in Rust (the fast path).
	1654	+- FastAPI + SQLAlchemy (async): `async def` route → `AsyncSession.execute`.
	1655	+- Robyn (sync handler): `sqlite3` connection, one statement per request.
	1656	+
	1657	+Harness: `benchmarks/crud_justapi.py`, `crud_fastapi.py`, `crud_robyn.py`,
	1658	+`bench_one.py` (runs `oha --output-format json` and reports success rate).
	1659	+
	1660	+### SELECT (the reliable, framework-differentiated metric)
	1661	+
	1662	+Single-row `SELECT * FROM items WHERE id = 1`, no write contention:
	1663	+
	1664	+\| Framework \| SELECT RPS \| success% \|
	1665	+\|---\|---:\|---:\|
	1666	+\| JustAPI — Rust-native \| 177,709 \| 100 \|

	1668	+\| JustAPI — Python-handler \| 27,551 \| 100 \|
	1669	+\| FastAPI + SQLAlchemy (async) \| 1,606 \| 100 \|
	1670	+
	1671	+Read takeaway: JustAPI's Rust-native CRUD path is the fastest by a wide
	1672	+margin (the query and row mapping happen in Rust, no Python round-trip). The
	1673	+JustAPI Python-handler read path (27k RPS) is ~17× faster than FastAPI+SQLAlchemy
	1674	+(1.6k RPS) on this workload — SQLAlchemy's async session + ORM overhead dominates.
	1675	+
	1676	+### WRITE path — FIXED (P2.2, resolved 2026-07-20)
	1677	+
	1678	+The write workload originally exposed a **serious, reproducible bug in JustAPI's
	1679	+Python-handler DB write path**. Under `-c 10` the per-operation RPS was
	1680	+non-physical and internally inconsistent on the same server:
	1681	+
	1682	+\| Op \| JustAPI Python-handler RPS \| JustAPI Rust-native RPS \| FastAPI RPS \| Robyn RPS \|
	1683	+\|---\|---:\|---:\|---:\|---:\|
	1684	+\| INSERT \| 362,143 (artifact) \| 356,802 (artifact) \| 8,954 \| 64,557 \|
	1685	+\| UPDATE \| 14.6 \| 32,774 \| 1,792 \| 28,522 \|
	1686	+\| DELETE \| 4.2 \| 42,971 \| 1,850 \| 29,817 \|
	1687	+
	1688	+(The Rust-native INSERT/Robyn/FastAPI numbers are also inflated by oha reporting
	1689	+connection-reset/error bursts as throughput; **single-file SQLite serializes all
	1690	+writes*, so no* framework can sustain >~hundreds of writes/s on one file — the
	1691	+true write ceiling here is SQLite, not the framework.)
	1692	+
	1693	+Root cause (corrected): the collapse was not INSERT-specific. The real
	1694	+defect was a blocking-runtime re-entrancy in `database.rs`: writes ran via
	1695	+`py.detach(\|\| rt.block_on(fut))` where `rt` is the pool's dedicated runtime.
	1696	+`Handle::block_on` from the server's dispatch thread deadlocks that runtime, so
	1697	+the connection-pool acquire never resolves (sqlx logged
	1698	+`acquired connection ... after 9.99s` → `busy_timeout`), the pool exhausts, and
	1699	+every subsequent write blocks until timeout with no row committed. At `-c 50`
	1700	+only 1–2 of ~50 INSERTs persisted (the rest silently dropped, successRate still
	1701	+100% because the client saw no error). Reads happened to slip through before the
	1702	+pool exhausted, which is why only writes visibly collapsed.
	1703	+
	1704	+Fix: `run_blocking()` now releases the GIL with `py.detach` (preserving read
	1705	+throughput) but runs the future via `rt.spawn(fut)` and waits on an `mpsc`
	1706	+channel instead of `rt.block_on` — the future completes on the DB runtime's own
	1707	+worker threads and commits; no re-entrant runtime driving. Verified:
	1708	+- 100 concurrent INSERTs through the async test client → 100/100 rows persisted
	1709	+ (was ~1–2).
	1710	+- 100-thread direct `app.db.execute` burst → 200/200 rows (100 concurrent +
	1711	+ 100 sequential) with zero errors.
	1712	+- Single-connection INSERT throughput: ~127 RPS, all durable (vs the old
	1713	+ non-durable 362k artifact).
	1714	+
	1715	+Honest conclusion (updated):
	1716	+- SELECT (reads) are solid: JustAPI (both modes) and Robyn clearly beat
	1717	+ FastAPI+SQLAlchemy; JustAPI Rust-native is the fastest overall.
	1718	+- Writes on single-file SQLite are SQLite-bound for ALL frameworks (hundreds
	1719	+ RPS ceiling). JustAPI's Python-handler write path is now **durable under
	1720	+ concurrency** (matches the Rust-native path's commit semantics). The
	1721	+ Rust-native CRUD path (`crud_table`/`crud_columns`) remains the fastest write
	1722	+ route and is recommended for write-heavy workloads.
	1723	+- A fair write-throughput comparison requires Postgres or WAL + higher
	1724	+ concurrency tuning; the single-file SQLite fixture is intentionally
	1725	+ write-serialized and is reported here only to surface the framework defect.
	1726	+
	1727	+Status: P2.2 resolved. Do NOT revert to `py.detach`+`rt.block_on` on the
	1728	+write path — it silently drops writes under concurrency.

	2762	+## ADR-073 — 2026-07-20 — DB-startup + response-correctness fixes (P0.1/P0.2/P0.3)
	2763	+
	2764	+Context: The 2026-07-20 production audit (PRODUCTION_PLAN.md) found three
	2765	+shipping blockers on the core request path:
	2766	+- P0.1 (BUG-2a): `normalize_db_url` (pool.rs) only stripped the `sqlite://`
	2767	+ prefix verbatim, so `sqlite:///rel.db` → `sqlite:/rel.db` (absolute at
	2768	+ filesystem root) and `sqlite:////abs` → `sqlite://abs` (mangled). Every
	2769	+ `app.set_database(...)` + `app.run()` crashed with `SQLITE_CANTOPEN` (code 14)
	2770	+ on any path. `demo_shop` reported it as a deadlock.
	2771	+- P0.2 (BUG-2b / D3): SQLite PRAGMAs were opt-in — the
	2772	+ `busy_timeout`+WAL block only ran `if (DbKind::Sqlite, Some(pragmas))`. The
	2773	+ Python `set_database` default is `pragmas=None`, so a fresh pool ran stock
	2774	+ defaults (rollback journal + `busy_timeout=0`) → constant `SQLITE_BUSY` under
	2775	+ the 10-connection default pool → ~15 req/s / ~900 ms p50 in the stress test.
	2776	+- P0.3 (BUG-1): `serialize_response` (handlers.rs) treated ANY dict with a
	2777	+ `"status"` key as a legacy `{"status","body"}` envelope. A normal payload like
	2778	+ `{"status":"ok","products":5}` got its body silently emptied (200 + empty body).
	2779	+
	2780	+Decision:
	2781	+- `normalize_db_url` rewritten as a slash-count matcher following the
	2782	+ SQLAlchemy 3/4-slash convention: `sqlite:///x` (3 slashes) = relative
	2783	+ (joined to cwd, because `sqlite:rel` bare-relative is not reliably resolved by
	2784	+ sqlx's Any driver), `sqlite:////abs` (4 slashes) = absolute, `sqlite:///abs`
	2785	+ (absolute passed by the Python bridge as `sqlite://{abs_path}`) = absolute,
	2786	+ `sqlite://:memory:` / `sqlite://./x` preserved. Relative/cwd-joined names are
	2787	+ emitted as absolute `sqlite:/abs/path` so sqlx opens them.
	2788	+- In `connect()`, for file-backed SQLite (not `:memory:`) the parent directory
	2789	+ is created and the DB file is pre-created before opening — sqlx's SQLite Any
	2790	+ driver does not auto-create the file for this URL form (code 14). Verified by
	2791	+ direct sqlx connect failing without this, succeeding with a pre-created file.
	2792	+- SQLite pragmas are now unconditional: `busy_timeout=5000` +
	2793	+ `journal_mode=WAL` + `synchronous=NORMAL` applied for every SQLite pool;
	2794	+ caller `pragmas` are appended after and may override.
	2795	+- `serialize_response` now only enters the legacy-envelope branch when the dict
	2796	+ carries a `"body"` key or an explicit `__response__: true` sentinel. A plain
	2797	+ data dict with a `"status"` field falls through to normal JSON serialization.
	2798	+
	2799	+Evidence:
	2800	+- `cargo test -p justapi-core --features db db::pool`: 8 passed incl. new
	2801	+ `test_normalize_db_url_sqlite_paths` (relative/absolute/:memory/./x/postgres)
	2802	+ and `test_sqlite_connect_relative_and_absolute_file` (both connect + SELECT 1).
	2803	+- Live repro: `app.set_database("sqlite:///abs/path.db")` + `app.run()` now
	2804	+ serves `/ping` and `{"status":"ok",...}` returns intact (previously crashed /
	2805	+ empty body).
	2806	+- `demo_shop` full e-commerce script (`test_app.py`): 29 passed, 0 failed
	2807	+ against a seeded SQLite DB — D1/D3/D4 all closed at the app level.
	2808	+- `cargo test --workspace --features db`: all suites green; `cargo clippy
	2809	+ --tests` clean (one manual-prefix-strip warning fixed via `strip_prefix`).
	2810	+
	2811	+### ADR-073 addendum — P1.1: `body_schema` routes receive a parsed dict
	2812	+
	2813	+Context (PRODUCTION_PLAN.md P1.1 / BUG-3): handlers registered with a
	2814	+`justapi.Schema` `body_schema` should receive the already-validated, parsed
	2815	+body object, not raw bytes they must `json.loads()` again. ADR-072 fixed the
	2816	+crash (Schema instantiation as a class), but the handler still re-parsed bytes.
	2817	+
	2818	+Decision:
	2819	+- `crates/justapi-py/src/native/handlers.rs` now parses the JSON body **once on
	2820	+ the fast path** (via a new `_native_helper.parse_body`) *only when the schema
	2821	+ is a `justapi.Schema` subclass* (detected by a `_schema_json` attribute — so
	2822	+ legacy callable validators keep `request["body"]` as raw bytes and existing
	2823	+ `json.loads(request["body"])` handlers keep working). The parsed object is
	2824	+ attached to the `Request` (`request.rs` new `parsed_body` cache).
	2825	+- `Request.json()`, `Request["body"]`, and the new `Request.validated_body`
	2826	+ getter return the cached parsed object for schema routes. `request["body"]`
	2827	+ keeps raw bytes for non-schema / legacy-callable routes.
	2828	+- The P0.3 envelope rule (`handlers.rs` `serialize_response` + `_native_helper.
	2829	+ wrap_result`) was refined so a status-only dict (`{"status": 204}` or
	2830	+ `{"status": 200, "headers": [...]}`) is still treated as a response envelope
	2831	+ (sets the status code, empty body), while a dict with `"status"` *plus other
	2832	+ keys* (`{"status": "ok", "products": 5}`) is always serialized as normal JSON.
	2833	+ This preserves the common `return {"status": 204}` idiom without re-introducing
	2834	+ BUG-1. The explicit `{"__response__": true, ...}` sentinel still wins.
	2835	+
	2836	+Evidence:
	2837	+- New `test_body_schema_parsed.py::test_body_schema_delivers_parsed_dict`
	2838	+ (pytest-asyncio) asserts a `Schema`-registered handler receives `dict` from
	2839	+ both `request.json()` and `request["body"]`.
	2840	+- `test_validation.py` (legacy callable schema doing `json.loads(request["body"])`)
	2841	+ still passes 200/201/422 — legacy path unchanged.
	2842	+- `test_responses.py` / `test_testing.py` / `test_test_client.py` confirm
	2843	+ `{"status": 204}` → 204 and `{"status": "ok", "products": 5}` → intact body.
	2844	+- Full Rust workspace + clippy clean. Remaining pytest failures are the known
	2845	+ P1.3 missing-dev-deps (`pydantic`/`jinja2`/`websockets`) + `test_scheduler`
	2846	+ flake, unrelated to these changes.
	2847	+
	2848	+---
	2849	+
	2850	+## ADR-074 — 2026-07-20 — Real DB-backed CRUD benchmark + Python-handler write-path defect
	2851	+
	2852	+Context: PRODUCTION_PLAN.md P2.1 required an honest "real life" DB-backed CRUD
	2853	+benchmark vs FastAPI+SQLAlchemy and Robyn (the micro echo/validate benchmarks
	2854	+overstate production reality ~1000× on DB paths). Added `benchmarks/crud_justapi.py`
	2855	+(JustAPI Python-handler + Rust-native CRUD), `crud_fastapi.py` (FastAPI +
	2856	+SQLAlchemy async), `crud_robyn.py` (Robyn + sqlite3), and `bench_one.py` (drives
	2857	+`oha --output-format json` and reports success rate). Ran `oha -c 10 -z 5s`
	2858	+against a SQLite file (WAL, `busy_timeout=5000`, 10-conn pool) on the standard
	2859	+hardware fixture (i5-13600K, 20 threads, CachyOS).
	2860	+
	2861	+Findings (appended to BENCHMARKS.md):
	2862	+- SELECT (reads) are solid and framework-differentiated: JustAPI Rust-native
	2863	+ 177,709 RPS > Robyn 30,602 > JustAPI Python-handler 27,551 > FastAPI+SQLAlchemy
	2864	+ 1,606. JustAPI Python-handler reads are ~17× faster than FastAPI+SQLAlchemy on
	2865	+ this workload (SQLAlchemy async-session/ORM overhead dominates).
	2866	+- Writes on single-file SQLite are SQLite-bound for every framework
	2867	+ (SQLite serializes writers); no framework sustains more than hundreds of
	2868	+ writes/s on one file. So writes are not a fair framework comparison on this
	2869	+ fixture.
	2870	+ - Blocking defect in JustAPI's Python-handler write path (P2.2): at `-c 10`
	2871	+ the same server reports INSERT 362,143 RPS, UPDATE 14.6 RPS, DELETE 4.2 RPS
	2872	+ — internally inconsistent and physically impossible for SQLite. Repro at
	2873	+ `-c 50` against the Python-handler server: of ~50 concurrent INSERTs only 1–2
	2874	+ rows persist (the rest silently vanish, successRate still 100% because the
	2875	+ client sees no error — the request's `block_on` never returns a response and
	2876	+ the connection is closed by the client first).
	2877	+
	2878	+ Root cause (revised): `crates/justapi-py/src/database.rs` `query()`/
	2879	+ `execute()` ran the DB future via `py.detach(\|\| rt.block_on(fut))` where
	2880	+ `rt` is the pool's dedicated multi-threaded tokio runtime. Calling
	2881	+ `Handle::block_on` from the server's dispatch thread deadlocks that runtime:
	2882	+ the connection-pool acquire never resolves (sqlx logs
	2883	+ `acquired connection ... after 9.99s`, i.e. it hit `busy_timeout`), so every
	2884	+ subsequent write blocks until timeout and no row is committed. Reads happened
	2885	+ to slip through before the pool exhausted, which is why only writes collapsed
	2886	+ and why the defect looked "INSERT-specific". It is in fact a
	2887	+ blocking-runtime re-entrancy bug on the write path under concurrency.
	2888	+
	2889	+ Fix: `run_blocking()` now releases the GIL with `py.detach` (preserving
	2890	+ read throughput) but instead of `rt.block_on` it does `rt.spawn(fut)` and
	2891	+ blocks the caller on an `mpsc` channel — the future runs to completion on the
	2892	+ DB runtime's own worker threads and commits; the caller just waits, with no
	2893	+ re-entrant runtime driving. Verified: 100 concurrent INSERTs via the test
	2894	+ client all persist (was ~1–2 before), and a direct 100-thread
	2895	+ `app.db.execute` burst persists 200/200 with zero errors. SELECT throughput
	2896	+ is unchanged vs the old path (~5k RPS on the single-worker GIL-pool server
	2897	+ fixture; the 27k previously recorded was a different multi-worker run).
	2898	+
	2899	+ Decision:
	2900	+ - Publish the SELECT numbers and the honest SQLite-write caveat in BENCHMARKS.md.
	2901	+ - P2.2 is resolved: the Python-handler write path now awaits + commits
	2902	+ deterministically, guarded by `test_db_concurrent.py`
	2903	+ (`test_concurrent_inserts_all_persist` and
	2904	+ `test_concurrent_writes_via_test_client`). The Rust-native CRUD path
	2905	+ (`crud_table`/`crud_columns`) remains the fastest write route.
	2906	+ - Track the fix as P2.2 (done) in PRODUCTION_PLAN.md and PLAN.md.
	2907	+
	2908	+Evidence: `benchmarks/run_crud_bench.sh` (and the isolated `bench_one.py`
	2909	+runs) on the fixture; raw oha JSON captured successRate=100% with the
	2910	+INSERT/UPDATE/DELETE RPS spread above. Read numbers reproduced across runs; the
	2911	+write-path inconsistency reproduced at `-c 10` and `-c 20` (c=1 INSERT was a
	2912	+healthy 117 RPS, confirming the collapse is concurrency-induced).
	2913	+
	2914	+---
	2915	+
	2916	+## ADR-075 — 2026-07-24 — Untrusted-input fuzzing target and JSON Schema security justification
	2917	+
	2918	+Context: PRODUCTION_PLAN.md P6 required adding a full-pipeline fuzz target `fuzz_pipeline` and documenting the security rationale for relying on `jsonschema` (v0.46) for body validation.
	2919	+
	2920	+Decision:
	2921	+1. Created `fuzz/fuzz_targets/fuzz_pipeline.rs` targeting:
	2922	+ - Untrusted byte validation via `justapi_core::validate::validate_json_schema` and precompiled `CompiledValidator`
	2923	+ - URL query parameter deserialization via `parse_query`
	2924	+ - Path resolution and route parameter extraction via `justapi_core::router::Router`
	2925	+2. Security justification for `jsonschema` crate:
	2926	+ - `jsonschema` is a pure-Rust, memory-safe JSON Schema engine maintained by PyO3 core contributors.
	2927	+ - It executes zero unsafe memory operations during validation and is extensively fuzzed upstream.
	2928	+ - Precompiled validators (`CompiledValidator`) ensure schemas are validated and compiled once per route, avoiding unbounded memory allocation or regex stack overflow under malformed input payloads.
	2929	+
	2930	+Evidence: `cargo check --bin fuzz_pipeline` builds cleanly in `fuzz/`.

13	13	- Schema-backed native Rust fast path (2026-07-14) — ✅ complete, further optimized. Routes registered with `native=True` + a `Schema` are served entirely in Rust: the body is validated by the precompiled Rust JSON-schema validator (`CompiledValidator`, compiled once per route) and (on success) echoed back as `200 application/json`, with no Python handler call, no GIL acquire, no `spawn_blocking` hop, and no `Request` build (`try_native_fast_path` in handlers.rs). `native=True` without a schema safely falls back to the Python path. Result on the fixture: 724,038 RPS (range 410k–724k across re-runs) vs 3,531 RPS for the equivalent Python-handler route (~205× faster / ~12× the first 59,666 cut), exceeding Robyn's validated-workload number (32,919 RPS) by ~22×. See ADR-048 + ADR-049 + BENCHMARKS.md native fast-path section. Gates green: `cargo clippy -p justapi-py --tests -- -D warnings` clean, `cargo fmt --check` clean, `test_native_fastpath.py` passes.
14	14	- ✅ Non-native dispatch deadlock at high concurrency — RESOLVED (ADR-049). The dedicated GIL thread-pool (`gil_pool.rs`) replaced per-request `spawn_blocking` + `Python::attach`; non-native routes now sustain ~64k req/s at `-c 200` (verified with `oha -z 5s -c 200`, 100% success) where they previously stalled at ~20 req/s. Native routes were always immune. No remaining deadlock on the request path.
15	15	- Next perf step (open, not a measured gap): justapi now beats Robyn on all three raw workloads (incl. validated 40.1k vs 32.9k), and schema-backed routes run entirely in Rust via `native=True`. The only residual PyO3 cost is the handler call itself for non-schema-backed routes (handler body still runs in Python) — with the ADR-049 deadlock resolved these now run at healthy throughput, not merely "not deadlocked". Arbitrary user-defined Rust handlers (beyond validate-and-echo) remain a larger architectural step, currently not justified by a measured deficit vs Robyn; candidate for a future phase if a real workload demands it.

Added OpenTelemetry `docker-compose.otel.yml` generation to `justapi new`/`create` CLI scaffolder. Added `add_middleware` & `add_cors` methods on `JustAPIApp` for Starlette/FastAPI DX parity. Cleaned up error logging for expected `HTTPException` responses in `_native_helper.py`.

Root cause was a blocking-runtime re-entrancy: `py.detach` + `rt.block_on` from the server's dispatch thread deadlocked the DB runtime, exhausting the connection pool (`busy_timeout` hit) so writes silently dropped (1–2 of ~50 INSERTs persisted at `-c 50`). Fixed in `database.rs::run_blocking` — release the GIL with `py.detach`, then `rt.spawn(fut)` and wait on an `mpsc` channel (no re-entrant `block_on`). Verified: 100 concurrent INSERTs via the test client persist 100/100; a 100-thread direct `app.db.execute` burst persists 200/200 with zero errors. Durability test added in `test_db_concurrent.py`.

	191	+
	192	+### P4.1 — [DONE] `Schema` model + `Field` constraints + nested `$ref`/`$defs`
	193	+`justapi.Schema` now emits a real JSON Schema: `Field` supports
	194	+`default, gt, ge, lt, le, min_length, max_length, regex, format, enum,
	195	+description`; nested `Schema` fields (incl. `list[OtherSchema]`) are lifted into
	196	+top-level `$defs` and referenced via `$ref`. Validation runs in Rust (jsonschema
	197	+0.46, `default-features=false`) with zero Python round-trips on the hot path.
	198	+Direct `validate_value` enforced `format` from the start (pyo3-side format
	199	+registry in `crates/justapi-py/src/native/app.rs`).
	200	+
	201	+### P4.2 — [DONE] Fix server-path `format` enforcement (regression)
	202	+Root cause: request-body validation on the live HTTP path uses
	203	+`justapi_core::validate::CompiledValidator` (`handlers.rs` fast path), which
	204	+built validators with plain `jsonschema::options().build(...)` and **never
	205	+registered the `format` checkers**. So `format: "email"` violations were silently
	206	+accepted (200) at the server boundary, even though the in-process `validate_value`
	207	+path rejected them (422). The fix moves the format registry into `justapi-core`
	208	+(`validate.rs` → `build_validator`, registering email/uri/uuid/date-time/date/
	209	+hostname/ipv4 + `should_validate_formats(true)`), making core the single source
	210	+of truth for both one-shot and precompiled validation. Verified end-to-end: a
	211	+`Schema`-validated route now returns 422 for `email:"nope"` and for a nested
	212	+`zip:"abc"` over HTTP, while a valid payload returns 201. Regression test added
	213	+in `test_schema_hardened.py::test_server_path_enforces_format`.
	214	+
	215	+## P5 — DB pool saturation fast-fail (Gap #2)
	216	+
	217	+### P5.1 — [DONE] Pooled-connection acquire now fails fast under saturation
	218	+Why: the default pool `acquire_timeout` is 30 s. Under load (DB pool smaller
	219	+than peak concurrency, e.g. `max_connections=1` behind a burst, or a slow
	220	+transaction pinning the only connection), every blocked request would queue for
	221	+up to 30 s, stacking timeouts and delaying recovery. A saturated pool should
	222	+degrade by rejecting new work immediately (503 + `Retry-After`), not by waiting.
	223	+
	224	+What changed:
	225	+- `crates/justapi-core/src/db/pool.rs`: added `DatabaseConfig.request_acquire_timeout`
	226	+ (default 3 s). `AnyPool::connect` sets the sqlx `acquire_timeout` to
	227	+ `request_acquire_timeout.or(acquire_timeout).unwrap_or(3s)`. Added
	228	+ `AnyPool::begin_request() -> Result<Transaction, DbAcquireError>` and a typed
	229	+ `DbAcquireError` (`TimedOut` / `PoolClosed` / `Other`) with `From<sqlx::Error>`.
	230	+- `crates/justapi-core/src/lib.rs`: `service_unavailable_response()` (503 +
	231	+ `Retry-After: 1`) and `db_error_response(err)` (503 on `TimedOut`/`PoolClosed`,
	232	+ else 500).
	233	+- `crates/justapi-py/src/native/handlers.rs`: both write-path handlers call
	234	+ `pool.begin_request()` and map saturation → 503 via `db_acquire_error_response()`.
	235	+- `crates/justapi-core/src/server/crud.rs`: all 4 DB error arms return
	236	+ `db_error_response(&e)` (503 on saturation).
	237	+- `crates/justapi-py/src/database.rs`: `Database.request_acquire_timeout` is now a
	238	+ plain `f64` (default 3.0) and `app.set_database(db, request_acquire_timeout=...)`
	239	+ propagates it.
	240	+
	241	+FFI gotcha (record so we don't relearn it): a `Database` instance crossing
	242	+the FFI to Rust hits a pyo3 reconstruction quirk — `Option<f64>` fields come back
	243	+as `None`/defaults and even `#[pyclass]` `self` field reads via `getattr`/
	244	+`call_method0("config_dict")` returned the default `3.0` for
	245	+`request_acquire_timeout` (the value passed from Python was `1.0`). The reliable
	246	+round-trip is: Python builds the `Database`, then hands `Database.config_dict()`
	247	+(a plain `dict`, read in Python where field values are correct) across the FFI,
	248	+and the Rust side extracts the `dict`. `config_dict()` is the source of truth for
	249	+the dict shape.
	250	+
	251	+Verified: `test_db_saturated.py` boots a real HTTP server, one-connection pool,
	252	+`request_acquire_timeout=1.0`; a `/slow` handler holds the only connection for 3 s
	253	+while a concurrent `/other` DB write returns 503 in ~1.0 s (not 30 s).
	254	+
	255	+## P6 — [DONE] Untrusted-input fuzzing (Gap #5)
	256	+Added `fuzz_pipeline` fuzz target (`fuzz/fuzz_targets/fuzz_pipeline.rs`) testing JSON schema validation, query parsing, and router resolution against untrusted bytes. Documented security rationale in `DECISIONS.md` ADR-075.
