Deterministic concurrent writer handling tests/test_compaction_telemetry.py |
The test patches _temporary_sqlite_busy_timeout, verifies the 100 ms production timeout, and delegates to a 5000 ms runtime wait for deterministic concurrent writes. |
Estimated code review effort: 2 (Simple) | ~10 minutes
Merge Risk: ⚪ Minimal · up to 4143a
This change makes the compaction telemetry concurrency test reliably validate two serialized updates without changing the production 100 ms contention policy. The updated test coverage is ready to merge.

…LOG header scope Review findings (evaos P3 + cross-model r1): the summary said three product fixes where #407 is test-only; #412 also recorded the #155 refactor row (ledger entry only) so the notes no longer claim no new ledger row; the CHANGELOG header now scopes the curated-notes claim to tags from v0.21.0-rc1 onward, which is where the notes directory actually starts.

Closes #328.
The atomic two-engine test intentionally overlaps both telemetry writers, but production is also intentionally allowed to abandon best-effort telemetry after 100 ms. Runner scheduling could therefore exercise a valid skipped sample while the test still required both increments.
This keeps the production 100 ms policy unchanged and replaces it only inside this regression with a 5 second SQLite wait. Both writers still begin together, so the test continues to prove cross-connection serialization and a final total of two.
