# β Close-out — Cycle #349

**Issue:** #349 — Activation §11a: operator access flow for notification channels  
**Merge commit:** 7a93d821  
**Review rounds:** 1 (R1 → APPROVED)  
**Total findings:** 0  

## Review Context

**Branch state at review:**
- Base: af1abef5076eace2f101eb10c8bc53a7f29e6684 (origin/main)
- Head: 4cc68cae02bc601dcb571d258f880865840e957d (α review-readiness signal)
- CI status: Build workflow SUCCESS
- Files changed: 2 (activation/SKILL.md + self-coherence.md)

**Review process executed:**
- Phase 1 (Contract Integrity): 10/10 checks PASS — no contract issues
- Phase 2a (Issue Contract Walk): 4/4 ACs met with concrete evidence  
- Phase 2b (Diff/Context Inspection): 13 checks applied, all PASS
- Phase 2c (Architecture Check): 7/7 boundaries preserved, transport-agnostic design confirmed
- Pre-merge gate: Identity + skill freshness + non-destructive merge test all PASS

**Narrowing pattern:** No narrowing required. Single round R1 → APPROVED due to complete AC satisfaction and zero implementation issues.

## Merge Evidence

**Merge execution:**
- Pre-merge gate completed successfully (3/3 rows PASS)
- Merge strategy: `git merge --no-ff cycle/349` 
- Merge result: Clean automatic merge, no conflicts
- Files integrated: activation/SKILL.md + .cdd/unreleased/349/self-coherence.md
- Working tree: Clean post-merge state

**Integration verification:**
- Merge-tree validator attempted (./tools/validate-skill-frontmatter.sh failed on missing `cue` prerequisite — environment limitation, not implementation issue)
- Zero unmerged paths confirmed
- Branch fully integrated into main at commit 7a93d821

## β-side Findings

**No new findings.** 

**Process observations:**
- α's self-coherence artifact provided complete AC evidence with accurate line numbers — no evidence-hunting required
- Transport-agnostic design pattern effectively separated policy from implementation detail
- Pre-merge gate throwaway worktree functioned correctly with explicit --worktree identity config
- Review skill three-phase structure provided systematic coverage without redundancy

**Skill application patterns:**
- docs-only mode appropriately N/A'd engineering-focused checks (snapshot tests, execution timeline, confinement validation)
- Architecture check activated correctly on registry design + transport semantics triggers
- All loaded skills (write/SKILL.md constraints visible in §11a prose structure; design/SKILL.md principles applied in transport-agnostic boundary design)

**Review-to-merge handoff:** Seamless. No missing context or authority gaps between review completion and integration execution.
