"""Phase 7.3 R1..R4: Lance storage periodic-maintenance test suite.
Forensic context (2026-04-27): production records.lance had grown to
10,841 versions / 3.66 GB for only 7,130 rows over 9 days. Offline
`table.optimize(cleanup_older_than=timedelta(days=1))` reclaimed 84% of
disk and dropped `build_runtime_graph` cold latency 13.3s -> 0.13s
(102x). wires that fix into the daemon as a periodic job.
Test scope (one file per phase concern, mirrors idiom):
1. Helper drops version count without losing rows.
2. Helper never raises on per-table failure (other tables still
processed; failed table's report carries `error` field).
3. Startup wire-in (the optimize call inside `daemon.main()`) emits
exactly one `lance_storage_optimized` event with `phase="startup"`.
4. Periodic skip on MCP-active emits `lance_storage_optimize_skipped`
with `reason="mcp_active"` and zero `lance_storage_optimized`.
5. Env override `IAI_MCP_LANCE_OPTIMIZE_INTERVAL_SEC=0.05` causes the
periodic body to run repeatedly; >= 2 events fire within 0.5 s.
6. Optional: periodic runs once the socket flips idle (gate is two-way).
CRITICAL idiom: project does NOT depend on `pytest-asyncio`. Every test
that drives `async def` code uses SYNC `def test_X(...)` wrapping
`asyncio.run(coroutine_body(...))`. See `tests/test_daemon_tick_flags.py:144`
for canonical idiom. Do NOT add `@pytest.mark.asyncio` decorators here.

Why retention=0: in the live daemon we use `timedelta(days=1)` so
same-session optimize runs are no-ops (versions are seconds old).
For the synthetic test we want to assert collapse on freshly-created
versions, so we pass an aggressive retention.

fresh MemoryStore and asserts the event appears with the right
payload shape.
Done in isolation (not by spawning the full daemon main loop) for two
reasons:
1) daemon.main() takes signal-handler ownership of SIGTERM/SIGINT/
SIGHUP and binds a unix socket -- a unit test would have to
tear all of that down.
2) The tested invariant is the EXACT call sequence at the wire-in,
which is what this test exercises.

# The D7.3-11 `_should_yield_to_mcp(socket)` gate inside the
# periodic Lance optimize body was removed in Task 1.4. The lifecycle

# longer reachable. The cooldown gate (interval-based) and the
# `lance_storage_optimized(phase="periodic")` happy-path emission are
# still exercised indirectly via `test_startup_wire_emits_one_lance_
# storage_optimized_event` above.

# locked by `test_module_constants_exist_with_documented_defaults`
