fix(deploy): L221 dedup_key on canary-rollback alert + lib pin v0.21→v0.24#287
Merged
Conversation
…v0.24
Adds ``--dedup-key "canary-fail-${FUNCTION_NAME}-v${VERSION}"`` to the
canary-rollback alert publish in ``infrastructure/deploy.sh``. The
2-day silent rollback chain that motivated L221 (alpha-engine-data
#274 retrospective — 10 consecutive rollbacks across 2 days,
operator missed them) would have produced 10 alerts pre-fix; with
the lib v0.24.0 dedup substrate, an image-wide rebuild that breaks
N consecutive canaries within the hour collapses to one alert per
(Lambda, version).
Originally filed as a P1 owed BEFORE the 4 L221 canary PRs merged;
those PRs merged 5/21 23:42-23:51Z so this is a post-merge retrofit
per the ROADMAP's downgrade rule.
Lib pin v0.21.0 → v0.24.0 in lockstep across requirements.txt +
Dockerfile (the [flow_doctor]-only Lambda install line — the EC2
[arcticdb,flow_doctor,rag] install resolves transitively from
requirements.txt). v0.24.0 ships the ``--dedup-key`` CLI flag this
retrofit relies on.
Full suite: 1425 passed, 1 skipped.
Composes with [[reference_alpha_engine_lib_alerts_v0_24_0_dedup]]
(consumer migration #6 of the v0.24.0 substrate, post-merge slice
completing the 4-repo L221 retrofit).

Summary
Why
The 2-day silent rollback chain that motivated L221 (10 consecutive rollbacks before operator notice) would have produced 10 alerts; now collapses to one alert per (Lambda, version) within the lib v0.24.0 60-min default window.
Originally filed as P1 owed BEFORE the 4 L221 canary PRs merged; those merged 5/21 23:42-23:51Z so this is a post-merge retrofit per the ROADMAP downgrade rule.
