# Code Review R012 — Step 4: Build + lint + race + live re-validation

Result: APPROVE

## Findings

No blocking findings.

The Step 4 diff only updates `STATUS.md` to mark the local quality gates and live MCP re-validation/cleanup as complete. The status entry is consistent with the approved Step 4 plan and does not introduce code or fixture changes.

## Verification

- Ran `git diff 3e35418..HEAD --name-only` and reviewed the full diff.
- Read the task prompt and updated `STATUS.md`.
- Independently re-ran the local quality gates:
  - `make build`
  - `make test`
  - `make test-race`
  - `make lint`
- All local gates passed.

Note: I did not repeat the live API write/delete smoke test during review to avoid creating additional real-account data; this approval relies on the Step 4 status assertion for that live validation, with the local gates independently verified above.
