# β Close-out — Cycle #354

## Review Context

**Issue:** #354 — δ must poll release CI after tag push — no silent release failures  
**Mode:** docs-only  
**Review rounds:** 1  
**Verdict:** APPROVED (R1)  

**Gap addressed:** δ pushes a tag, release workflow fires, but nobody monitors it. Release failures were silent until human notice. Evidence: v3.66.0 release smoke failed (binary version-pin mismatch), Telegram notification fired but no role acted.

**Solution implemented:** Added CI polling requirement to δ release process, completing the triad of CI gates across β (cycle CI before APPROVED per rule 3.10), γ (post-merge CI before close-out per §2.7), and δ (release CI after tag push per new §3.4 step 4).

## Narrowing Pattern

**R1 Initial Review:**
- Contract integrity: ✓ All checks passed, truthful status claims, verified canonical paths
- AC coverage: ✓ All 5 ACs met in diff
- Implementation quality: ✓ Clean docs amendment with proper cross-references
- Architecture: ✓ Preserves role boundaries, completes symmetric CI monitoring pattern
- CI status: ✓ All workflows green on review SHA 83c8303d

**No narrowing required** — clean initial implementation met all requirements.

## Merge Evidence

**Merge commit:** c18e0a67  
**Merge command:** `git merge --no-ff cycle/354` into main  
**Auto-close:** `Closes #354` included in merge commit message  
**Push confirmation:** `77a1c024..c18e0a67 main -> main`  

**Pre-merge gate verification:**
1. ✅ Identity truth: `beta@cdd.cnos` 
2. ✅ Canonical-skill freshness: origin/main unchanged (77a1c024)
3. ✅ Non-destructive merge-test: clean merge in throwaway worktree, cycle 354 validator passes

**Files modified:**
- `operator/SKILL.md` — algorithm step 6 + §3.4 step 4 (CI polling mechanism)
- `release/SKILL.md` — §2.7 cross-reference to δ CI polling authority
- `.cdd/unreleased/354/self-coherence.md` — α's complete branch artifact 
- `.cdd/unreleased/354/beta-review.md` — this review record

## β-side Findings

**Process observations:**
- Clean docs-only cycle with symmetric architecture completion (β/γ/δ CI monitoring triad)
- Pre-merge gate executed completely per `beta/SKILL.md` — identity verified, skills fresh, merge tested
- Release gate validator correctly detected cycle 354 as passing validation (small-change/docs-only treatment)
- Self-coherence artifact was complete and accurate to implementation

**Quality patterns:**
- α provided precise line-number evidence for all AC claims
- Cross-references were accurate between `operator/SKILL.md` and `release/SKILL.md`
- Gap was real and well-evidenced (v3.66.0 release failure)
- Implementation matched the architectural pattern of existing CI gates

**No β-side friction identified** — cycle executed cleanly within established process bounds.

## Next Actions

Per CDD lifecycle:
- α close-out: Required via δ re-dispatch after this merge (CDD.md §1.4 α step 10)
- γ PRA: Required after α close-out complete 
- Release boundary: This is docs-only mode — merge commit IS the disconnect per `release/SKILL.md` §2.5b
- Self-application: Cycle will self-apply new δ CI polling process when next release occurs

**β responsibilities complete** — handoff to γ for cycle closure.
