I read this as a final read-only quality audit of immutable candidate `653cc2f0...c7a723` - I’ll inspect the existing evidence and code closure, run only necessary targeted offline diagnostics, then append the uniquely named redacted receipt with a strict PASS/FAIL.


The immutable identity and Gates 18-20 are internally consistent so far. I’m now checking the remaining quality-specific closure: exact predecessor delta, controller repair, Ruff/ty/formatter classification, deterministic-test evidence, and whether every historical FAIL is explicitly closed rather than merely superseded.


The remaining diagnostics distinguish baseline debt from the candidate delta: Ruff is clean; `ty` is clean on the only changed source and repaired controller closure, while 25 diagnostics occur only in unchanged `test_status.py`; formatter failures reproduce on both predecessor and successor, and the sole successor diff is already formatter-stable. I’m recording the final receipt with those debts disclosed, not suppressed or charged to the PID fix.


I read this as the completed final quality audit - reporting the immutable-candidate verdict and receipt.

**PASS** — code-quality lane for candidate `653cc2f0...c7a723`.

- No blocking findings.
- Low: inherited formatter baseline; predecessor and successor are both red.
- Low: 25 inherited `ty` diagnostics in unchanged `test_status.py`.
- Candidate-caused scope: Ruff clean; `ty` clean.
- Gates 18/19/20: PASS; Gate20 not rerun.
- Gate20 baseline: 8,138 passed, 59 skipped, 0 failed.
- Exact delta: one source entry, `gateway/status.py`.
- Source/wheel mismatches: 0.
- Candidate/source drift: none.
- No product, test, profile, runtime, archive, service, network, Telegram, provider, or Git actions.
- No temporary files created.
