# β Close-out — Cycle #352

## Review Context

**Issue:** #352 — cdd/review+gamma: Add CI-green gate — β refuses merge on red CI, γ PRA verifies post-merge

**Mode:** docs-only, design-and-build  
**Scope:** 4-file coordination adding symmetric CI-green gates to CDD protocol

**Review rounds:** 2  
- R1: REQUEST CHANGES (1 finding: CI-green gate logical gap)
- R2: APPROVED (F1 resolved, CI verified green)

**Review pattern:** Initial implementation was structurally correct but operationally void due to workflow configuration gap. α resolved by enabling CI on cycle branches. Implementation quality high with clean cross-skill integration.

## Merge Evidence

**Branch:** cycle/352  
**Merge commit:** `ccfb3a77c77b7b3a6f85a8d32b51ae8a7c9f2c38`  
**Merge method:** `git merge --no-ff` with `Closes #352`  
**CI status at merge:** GREEN — Build workflow successful on cycle branch head  
**Pre-merge gate:** Passed (identity verified, canonical skills current, non-destructive merge-test successful)

**Files merged:**
- `.cdd/unreleased/352/` artifacts (self-coherence, beta-review, cdd-iteration)  
- `.github/workflows/build.yml` — cycle branch triggers added  
- 4 CDD skill files — CI-green gate rules implemented per ACs

**Branch state:** Clean merge, no conflicts, 8 files changed, 310 insertions, 5 deletions

## Implementation Assessment

**Rule coordination quality:** Excellent. All 4 skill surfaces (review, gamma, post-release, release) maintain consistent "required workflow" definition pattern and cross-reference coherently.

**AC coverage:** Complete. All 5 ACs have greppable evidence and proper implementation:
- AC1: Rule 3.10 binding CI-green gate in review/SKILL.md  
- AC2: Post-merge CI verification in gamma + post-release skills
- AC3: Grade cap clauses in release/SKILL.md §3.8
- AC4: §9.1 trigger amendment in post-release/SKILL.md  
- AC5: Self-applied successfully (cycle demonstrates its own discipline)

**Self-coherence:** High. The cycle that adds CI-green gates properly applied CI verification in its own review and merge process.

## Cycle Findings

**Pattern observed:** Initial rule implementation can be structurally sound but operationally void when repository configuration doesn't support the rule's assumptions. The CI-green gate rule assumed CI runs on cycle branches; the repository's workflow configuration didn't support this assumption.

**Resolution effectiveness:** α's fix (enabling CI on cycle branches) directly addressed the operational gap and made the rule operative. The fix was minimal and targeted — adding `'cycle/*'` to workflow triggers — without changing the rule architecture.

**Review discipline:** The binding CI verification prescribed by rule 3.10 was properly applied in R2. CI status was verified green before APPROVED verdict, demonstrating the gate is now operative.

**Engineering level:** The 4-file coordination demonstrated good CDD protocol engineering. Rule additions integrated cleanly with existing skill boundaries and maintained consistent terminology across surfaces.

## Process Observations

**Review effectiveness:** The 2-round review pattern (RC → fix → APPROVED) properly caught the operational disconnect between rule intent and repository configuration. B-severity classification was appropriate — significant incoherence but non-blocking to intent.

**Fix quality:** α's resolution was well-targeted and documented. The fix-round appendix in self-coherence.md properly captured the resolution with commit evidence.

**Gate operability:** Rule 3.10 is now fully operative. Future β reviews can mechanically verify CI status on review SHA and block merge on red/pending CI per the binding constraint.

**Cross-protocol inheritance:** The CI-green gate pattern establishes a precedent for other c-d-X protocols. The same discipline (pre-merge + post-merge CI verification) can be inherited by cdw and future protocols.

---

**Release readiness:** Merge completed successfully. The cycle artifacts are ready for γ triage and release processing per `release/SKILL.md`. This concludes β responsibility for cycle #352.
