Failure evidence

Gitea Actions run 1026 (push to main at commit 0c71dea00c47) failed in tests/test_live_snapshot.py::test_live_snapshot_reuses_completed_snapshot_inside_freshness_window[asyncio]: expected user_calls == 1, observed 0. The same checkout passed locally, indicating a scheduler-sensitive race in the test or snapshot coordination. Build and release-candidate jobs were blocked.

Acceptance criteria

  • The test deterministically observes the first snapshot computation before asserting coalescing behavior.
  • The focused test passes repeatedly without timing-dependent polling.
  • Full python3 -m pytest tests/ -q passes.
  • A Closes #N PR contains test evidence and restores green CI/release flow.
