[SoundMindsAI]

Summary

Finalization for chore_studies_post_arq_spy_fixture (PR #476, squash-merged ed85d84). Docs-only — no code.

• Moves the feature folder → implemented_features/2026_06_05_studies_post_arq_spy_fixture/ (flat, date-prefixed).
• pipeline_status.md: Implementation → Complete + **Release:** mvp2.
• implementation_plan.md: Status → Complete (PR test(studies): arq_pool_spy fixture for POST /api/v1/studies enqueue assertions #476).
• state.md: prepend the merge one-liner (drop the 6th → older-entries line); flip Current branch / In flight to the 3-chore afternoon queue (docs: reorganize into numbered IA, add pipeline skills and feature templates #1 shipped, docs: MVP1 architecture + 12 feature specs + GPT-5.5 review fixes #2 chore_demo_seeding_integration_tests_rewrite next).
• state_history.md: full reasoning entry.
• Regenerated dashboards + website/docs/roadmap.md.

No tracking issue for this slug. No phase*_idea.md (single-phase). Alembic head unchanged (0023).

Test plan

• dashboards + roadmap regenerated (deterministic)
• state.md under 60 KB gate (26,028 bytes)
• folder move verified; edits to pipeline_status.md/implementation_plan.md captured (542 insertions, edit-then-git-mv pitfall checked)
• CI (docs-only paths)

There is an unmatched closing parenthesis ) after NOT autouse in this line. It should be corrected to maintain proper grammar and readability.

Suggested change

**The fixture (Story 1.1, `integration/conftest.py`).** `SpyArqPool.enqueue_job` records each call as a flattened `(name, *args)` tuple (so the handler's `enqueue_job("start_study", study_id)` records `("start_study", study_id)`) and returns a truthy sentinel mirroring `ArqRedis.enqueue_job`'s "returns a Job on accept" contract. `install_arq_pool_spy(app)` is a contextmanager that captures the prior `app.state.arq_pool` via a `_UNSET` sentinel and restores it exactly on exit — `delattr` when the attr was originally unset (the Redis-down boot case), reassign otherwise. The `arq_pool_spy` pytest-asyncio fixture depends on `async_client` so it installs **after** the lifespan built (or skipped) the real pool — the install-after-lifespan ordering is the load-bearing detail (a success-path recorded call proves the spy, not the real pool, got the enqueue). NOT autouse, so tests that don't request it are unaffected. 5 unit tests (`test_arq_pool_spy.py`) lock the recording shape + truthy return + coroutine contract with no DB.

The `arq_pool_spy` pytest-asyncio fixture depends on `async_client` for install-after-lifespan ordering (NOT autouse) in `integration/conftest.py` + 5 unit tests; (1.2) wired the fixture into 13 studies-POST tests — 10 rejection paths assert `spy.calls == []`, 3 success paths assert `spy.calls == [("start_study", <id>)]` (proves the spy not the real pool received the enqueue → confirms install ordering) — plus 2 AC-3 restore tests each forcing their own precondition so both restore branches run deterministically every CI run regardless of whether Redis was up at boot, and restore the original boot state in `finally` so the real pool isn't stranded from lifespan shutdown's `aclose()`. Counts verified: 13 params, 10 `== []`, 3 `== [("start_study", …)]`.
