OBJECTIVE: Harden the acme-widgets service for the beta cut.
SUCCESS CONDITION: The full suite passes and staging runs 24h without a p95 regression.

The session opened with a long discussion about naming, weekend plans, and
whether the logo should be teal. None of it changed any engineering decision.
Then the agent spent a while exploring the repository layout: it listed the
services directory, opened services/widgets/README.md, skimmed the store and
api packages, and read through the connection-pool module twice before doing
anything. It printed the full dependency tree, which scrolled for a couple of
hundred lines, and summarized that nothing unusual stood out. It then ran the
test suite once just to see the baseline; 214 tests passed, 3 were skipped,
and the wall time was around ninety seconds. All of this was useful in the
moment and none of it needs to be replayed verbatim to continue the work.

There was also a false start around instrumentation: the agent drafted a
middleware-based timing hook, realized halfway through that the framework
already exposes per-route timing, deleted the draft, and moved on without
committing anything. The chat about whether to use histogram buckets of 50ms
or 100ms went back and forth for a while and ended without a firm decision;
nobody wrote it down as a requirement, so it stays an open thread in the raw
log rather than a recorded constraint.

DECISION: Host the beta on the shared acme-platform cluster.
DECISION: Host the beta on a dedicated small cluster, because noisy neighbors
  on acme-platform caused the March latency incident.
SUPERSEDES: Host the beta on the shared acme-platform cluster.

DECISION [CONTESTED]: Adopt a weekly release cadence for the beta period.
DECISION [UNVERIFIED]: Product reportedly wants SSO before beta; unconfirmed hearsay.

CONSTRAINT: Never run schema migrations against the production database from a laptop.
CONSTRAINT [EXACT]: Keep p95 read latency under 250 ms at 400 rps.
CONSTRAINT [EXACT]: Deploy to staging only with `make deploy ENV=staging TAG=beta`.
INVARIANT: The public API stays backward compatible within the v1 prefix.

COMPLETED: Connection pool rewrite merged and load-tested.
COMPLETED: Flaky test quarantine emptied; suite is green twice in a row.

FAILED APPROACH: Caching whole responses in Redis; cache invalidation bugs
  produced stale order totals in checkout and the approach was abandoned.

ARTIFACT: services/widgets/src/store/pool.py
ARTIFACT: commit 4f2a9c1e7b3d5a20

Someone pasted a partial stack trace here and the discussion moved on before
anyone confirmed whether it was from staging or a laptop run. The trace showed
a timeout in the pool acquire path, but the pool rewrite landed after the
trace was captured, so it may simply be stale. There was a long tangent about
whether the ORM retries on serialization failures, with three people quoting
different versions of the documentation; the thread ended with someone
promising to check and never reporting back. The agent also produced two
exploratory diffs it later discarded, and pasted the output of a profiling
run whose flame graph mostly confirmed what the March incident review had
already established about connection contention under burst load.

Near the end of the session there was scheduling chatter: who is on call for
the beta window, whether the dashboard review can move to Thursday, and a
reminder that the platform team freezes deploys on Friday afternoons. Someone
suggested renaming the beta cluster and was talked out of it. A draft of the
beta announcement email was pasted, edited twice for tone, and handed off to
marketing; the email content has no bearing on the engineering work tracked
here.

OPEN QUESTION: Do we need a read replica for the reporting endpoints before beta?
OPEN ACTION: Wire the latency histogram into the staging dashboard.

STOP CONDITION: Stop the rollout if error rate exceeds 0.5% for 10 consecutive minutes.

NEXT ACTION: Run `pytest -q tests/store` and fix the first failure before touching the dashboard work.
