# Independent final review

Review run: `20260907-232518-cacfc23f`. Skill: `ce-code-review mode:agent depth:full`. Status: **complete**. Original verdict: **Ready with fixes**.

The review covered all 27 changed files from baseline `7d64d2ba1329e06400446d1c755750b1ea5f033b` to application head `471337daa8b00f49028e11ff0d471411add1d0da`, using the authorized U1–U4 plan. All four implementation units were assessed as met.

Eight independent GPT-6 Astra agents at ultra effort completed: correctness, adversarial, security, testing, project standards, maintainability, reliability, and frontend lifecycle. A separate validator confirmed the sole actionable finding. No selected reviewer was lost, skipped or uncollected. Capacity limited this final roster to one child at a time. Reviewers inspected source without booting Rails, touching databases or making network calls; the parent executed the runtime verification separately.

Cross-model review was disabled for this run. These are independent contexts within the same model family, not corroboration by different models.

## Actionable finding and follow-up

**#1 · P2 · Deadline test depends on real scheduling.** The fallback test shortened its deadline to 10 milliseconds and slept to exhaust it. A scheduling pause before the first socket attempt could fail the test even when production behavior was correct. The validator confirmed the reasoning independently.

**Applied in `93e67d028`.** A synthetic monotonic time stays below the deadline until the first socket attempt, then advances beyond it inside that attempt. The test explicitly rejects a second address and asserts the same safe deadline error. No production deadline or transport behavior was relaxed. The same follow-up removes four introduced style offenses. A separate Astra ultra worker applied the fix; the parent reviewed the two-file diff. Focused verification: **88 examples, zero failures**, seed 20137. No actionable review finding remains unapplied.

## Advisory coverage opportunities

These were recorded as test-coverage opportunities, not confirmed production defects or unresolved actionable findings:

- Add a committed successful first-time database preparation lifecycle case. Current automated preparation cases exercise substituted pools with an existing database; real isolated preparation was also exercised during this run.
- Extend changed-versus-identical comparison assertions across the other four upload types.
- Add a Stimulus reconnection case with replace-all already checked.

## Evidence and limits

At the reviewed application head, the parent ran the full suite twice: **2,609 examples, zero failures**, seeds 10459 and 83719. Five more discovery cases account for the count difference from the earlier 2,604-example integration run. After applying the finding, the parent reran the full suite on final application commit `93e67d028`: **2,609 examples, zero failures**, seed 83719. The focused follow-up also passed 88 examples, zero failures.

The initial CLI ultra review attempts failed before inspecting code because of a nested sandbox error. They provided no verdict. Subsequent successful static reviews, the native final roster and its validator are the review evidence used here.
