# β close-out — cycle/397

**Issue:** cnos#397 — Phase 4a of #366
**Verdict:** R1 APPROVE (no findings)
**Reviewer:** delta@cdd.cnos (β-collapsed-on-δ)

## Review

R1 final review at `.cdd/unreleased/397/beta-review.md`. All 7 ACs PASS:

| AC | Status | Notes |
|---|---|---|
| AC1 | PASS | Frontmatter complete; all 7 required fields + operator-matching extras |
| AC2 | PASS | Two-sided membrane (§1 outward + §2 inward); cross-references on each side |
| AC3 | PASS | §3a substance moved entirely to delta/; operator/ retains redirect only |
| AC4 | PASS | Override-as-degraded-action; verdict-vs-decision distinction with biconditional |
| AC5 | PASS | 4 δ-role-content refs updated (γ×2, α×1, β×1); non-δ-role refs preserved |
| AC6 | PASS | operator/SKILL.md retains §1, §2, §3 mechanics, §3.4 runbook, §5-§10, kata |
| AC7 | PASS | No release-script mechanics in delta/; only authority-naming context |

## β-rigor checks (per dispatch instruction)

- Implementation-contract conformance verified (cnos#393 Rule 7): all 7 axes pinned in issue body satisfied per diff inspection.
- No δ-content lost: row-by-row mapping of removed operator/SKILL.md paragraphs to delta/SKILL.md paragraphs documented in self-coherence.md §3 and re-verified in beta-review.md §2.2.
- No broken cross-references: internal operator/SKILL.md refs and external γ/α/β refs all resolve to existing sections in delta/SKILL.md.
- Phase 4b/4c surfaces untouched: dispatch configs, harness quiescence, timeout recovery, embedded kata, wave coordination, release-script runbook all retained in operator/SKILL.md; release/SKILL.md, post-release/SKILL.md, CDD.md, activation/SKILL.md, review/SKILL.md, doctrine surfaces all unchanged.

## Findings

None.
