01a08ae8 - Overlap A38 jobs across distinct lock domains

[davidleomay]

EN:
An A38 run no longer waits for Docker before starting Jest, or for Jest before starting Docker. Jobs in different lock domains may run at the same time, with a default cap of two in flight. Lint, type-check and Jest still share a CPU domain so they do not overlap. Named locks stay exclusive across processes. Acceptance is still one complete run on the final clean head.

DE:
Ein A38-Lauf wartet nicht mehr auf Docker, bevor Jest startet, und nicht auf Jest, bevor Docker startet. Jobs in verschiedenen Lock-Domänen dürfen gleichzeitig laufen, standardmässig höchstens zwei. Lint, Type-Check und Jest teilen sich weiterhin eine CPU-Domäne und überlappen sich nicht. Benannte Locks bleiben prozessübergreifend exklusiv. Abnahme bleibt ein vollständiger Lauf am finalen sauberen Head.

Details

Behaviour

• load_policy stores lock on each normalized job (compose / http-smoke default docker-heavy).
• Conflict keys: docker-heavy is its own domain; every other job is #cpu plus its named lock.
• A38_MAX_IN_FLIGHT (default 2, integer ≥ 1) caps concurrency.
• Report table stays in policy order. verify_report is unchanged.
• After a job failure, independent jobs still run. Dirty tree or HEAD change still stops further starts.

Tests

python -m pytest tests/test_a38.py tests/test_a38_jobs.py -q → 157 passed, 22 subtests passed.

Details

Grok and Codex quality/logic on head 2c31a51. Iterations: executor lock key, docs (policy-order table, in-run vs cross-process locks, lock grammar), drift abort of in-flight peers, OSError via the future, KeyboardInterrupt inside the executor with block. Test-robustness nits (host A38_MAX_IN_FLIGHT, wall-clock bound, failure-continue start order) were not counted. Mergeable MERGEABLE / CLEAN. GitHub pytest SUCCESS. No review threads.
