# β close-out — cycle/399 (Phase 4c of cnos#366)

**Reviewer:** β-collapsed-on-δ (operator/SKILL.md §5.2 single-session δ-as-γ; γ+α+β collapsed on δ-as-agent).
**Verdict:** R1 APPROVED.

## What β reviewed

- New skill: `src/packages/cnos.cdd/skills/cdd/release-effector/SKILL.md` (~280 lines).
- Edits to: `operator/SKILL.md`, `release/SKILL.md`, `gamma/SKILL.md`, `activation/SKILL.md`, `CDD.md`, `COHERENCE-CELL.md`, `post-release/SKILL.md`.
- Cycle directory artifacts: `gamma-scaffold.md`, `design-notes.md`, `self-coherence.md`.
- Non-modification of `scripts/` (release.sh + dependents).

## Verdict per AC

| AC | Verdict | Notes |
|---|---|---|
| AC1 | PASS | release-effector/SKILL.md exists with frontmatter parsing cleanly |
| AC2 | PASS | 0 hits for `scripts/release.sh\|tag creation\|branch cleanup\|release CI` in operator/SKILL.md |
| AC3 | PASS | Tag policy lives in release-effector §2 with verbatim CDD §5.3a citation; surface inventory table covers all 7 surfaces |
| AC4 | PASS | Doctrinal frame stays in operator/SKILL.md §3.4; mechanical algorithm + recovery runbook + branch cleanup procedure relocate to release-effector; no content lost |
| AC5 | PASS | release/SKILL.md diff = 2 cross-ref lines; β-side substantive content untouched |
| AC6 | PASS | 8 skill files reference release-effector; every §3.4 cite now paired with a release-effector cite |
| AC7 | PASS | git diff -- scripts/ = 0 lines; release-effector §1 mechanical narration matches scripts/release.sh lines 1–119 |

## Implementation-contract conformance (cnos#393 Rule 7)

All 7 contract axes verified row-by-row in `beta-review.md`. PASS unconditionally.

## Disconnect-release semantics (explicit verification)

- Bare X.Y.Z + annotated only + one-tag-per-release + manual-tagging prohibition + CI-green gate + tag-as-signal + v-prefix legacy/warn-only + release-is-structural — all preserved in release-effector or operator/SKILL.md doctrinal frame.
- The v3.66.0/v3.67.0 empirical anchor (operator-override-for-pre-existing-infra-failures) is preserved in release-effector §4 step 5.
- Cross-references between operator §3.4 doctrinal frame and release-effector §1/§2/§3/§4/§5/§6 mechanics are bidirectional and consistent.

## β/δ release boundary

- release/SKILL.md retains β-side authoring (RELEASE.md, CHANGELOG, version decision, cycle-dir move, validators, deploy, validate, TSC scoring).
- release-effector adds δ-side mechanics (script invocation, post-push CI polling, CI-red recovery, branch deletes).
- release-effector §8 explicitly disclaims authoring + scoring + deployment + override authority. Boundary intact.

## Findings

**None binding.** No A / B / C / D findings.

## Merge

β authority to merge is delegated to δ-as-agent under operator/SKILL.md §5.2 (β's `git merge` step). Merge will execute as the closure step:

```
git checkout main
git pull --ff-only origin main
git merge --no-ff cycle/399 -m "Merge cycle/399: release-effector skill (Phase 4c of #366)"
```

No conflict anticipated (no other cycle/397/398 branches on origin; only release/SKILL.md, gamma/SKILL.md, operator/SKILL.md, CDD.md edits which were last touched at f891f08b and earlier — pre-cycle/395 merge).

## TSC grading (β assessment per release/SKILL.md §3.8)

Per the configuration-floor clause: γ-axis capped at A− because cycle/399 ran under §5.2 (γ/δ separation absent).

- **α** — A. All ACs met first pass; no β fix-rounds; implementation-contract conformance row-by-row PASS; faithful 12-step script narration.
- **β** — A. Honest review against all 7 ACs + the rule-7 axis + Phase 4a/4b non-interference; no missed findings.
- **γ** — A− (configuration-floor cap). γ+α+β collapsed on δ-as-agent under §5.2; coordinator scope reasonable for the design surface but the structural absence of γ/δ separation triggers the cap.

C_Σ ≈ (4.0 · 4.0 · 3.7)^(1/3) ≈ 3.89 → A (rounding to the closest letter grade). β notes that γ writes the PRA separately if/when this skill cycle is bundled into a versioned release.
