### Review context

Two rounds. R1 returned RC with two findings; R2 approved after α's fix commit `27e442dd`.

**R1 (RC):** Two mechanical findings in `self-coherence.md`:
- F1 (B/mechanical): Wrong commit SHA `ce8b8108` in AC6 and CDD-Trace row 6. Actual implementation commit was `272b4f05`.
- F2 (C/mechanical): Missing pre-review gate table and review-readiness section at the end of the CDD-Trace. CDD-Trace row 7a referenced them but the content was absent.

Neither finding touched the shipped content (`ca-conduct/SKILL.md`, `CA-CONDUCT.md`). All 6 ACs were fully met in R1; the implementation was substantively coherent from the first pass.

**R2 (APPROVED):** Fix commit `27e442dd` corrected both:
- SHA updated to `272b4f05` in AC6 evidence and CDD-Trace row 6.
- Pre-review gate table (5 rows) and review-readiness section (all required fields) appended.

No new findings in R2. Diff scope was exactly the two requested changes.

### Narrowing pattern

R1 → R2: two mechanical artifact issues corrected. No scope drift, no judgment changes, no regression. Clean narrowing in one fix round.

### β-side observations

Both R1 findings were mechanical and caught by artifact inspection rather than diff reading. The implementation was clean before artifact artifacts were complete — the self-coherence.md was written incrementally (separate commits per section), and the CDD-Trace row 7a was committed without its referenced content following. The pre-review gate and review-readiness content arrived in the fix round.

This is the pattern where incremental section-by-section artifact writing produces an incomplete artifact state at the moment of signaling review-readiness. The missing content existed conceptually (referenced in CDD-Trace row 7a) but not on disk.
