From flaky ticket to merged PR in fifty-four minutes

REV-198 → PR #347, squash-merged to main as eca10b0. 230 tool calls, 7 subagents, 9 skills — and two points where a human said yes.

The ask · Jira REV-198

Three tests failed once each, then passed on re-run at the identical tree.

CI is disabled, so local runs are the only evidence there is. Scope was fixed by the ticket: test files only, no production code.

Gate 1 · human decision · 02:02 → 02:34

The run stopped and asked a human before writing any code.

It put the whole diagnosis in front of the operator in plain language — one paragraph per test, naming the exact file and line, the fix, and what it deliberately would not do. It also flagged the limit of its own work: these fixes cannot stop an outside writer touching the shared database.

Operator answeredApprove — implement exactly this triage and plan

Build · test-first · 04:14 → 18:40

Every fix was proven by breaking it first.

Review · three agents, in parallel · 19:51

Three reviewers ran at once, and two of them converged on the same residual flake.

The flood test could pass with fetch_count at zero — a 401-before-JWKS path never reaches the endpoint. It gained the floor assertion its own docstring already claimed.

Finding 01 · deviation from acceptance criterion 1

The ticket’s own acceptance criterion could not pass.

The prescribed watermark — created_at >= clock_timestamp() — was implemented verbatim and failed. The run measured why rather than tuning it green: created_at carries the transaction’s transaction_timestamp(), landing 0.04–2.05s before the PATCH. It excludes the row it selects.

Finding 02 · found, proven, deliberately not fixed

A test-only ticket surfaced a real production bug.

Impact is low: rotation runs from a single scheduled job, and the reader takes ORDER BY created_at DESC LIMIT 1.

Finding 03 · the panel corrected itself · 42:14

A reviewer retracted its own claim before it reached main.

In round one it asserted a mechanism — that a FOR UPDATE lock serialized the two concurrent rotations — and a docstring was written to match. In round two, the same reviewer found that claim was wrong.

Verification · read off the final tree · 44:00

Twenty of twenty iterations green. 2,145 passed, zero failed.

Gate 2 · merge approval · 51:56 → 52:25

The merge request named the two things the operator should weigh before deciding.

Operator answeredMerge #347 into main (squash, delete the branch)

Shipped · 14:49:29 UTC

eca10b0 is on main. Four files, +106 / −33, no production code.

Branches deleted, local main fast-forwarded, working tree clean. REV-198 closed Done with all five stage sub-tasks. Five items were left open on purpose — each written into the pull request rather than carried in someone’s head.
