# Beta Close-Out — Cycle #345

## Review Context

**Issue:** #345 — Document the generic α/β/γ/δ/ε role-scope ladder as a cnos-level pattern
**Mode:** docs-only
**Branch:** `cycle/345`
**base SHA (origin/main at review):** 347a5e65366ac021479fc92469742681d32d0d2e
**cycle/345 head at review:** 36bba153588e4d985cec315b526ab0993ab16a3c
**β verdict SHA (beta-review.md commit):** 7fcf71ba
**Merge commit SHA:** 9513362a89b1e11821ea90bdb61091557efcd3ac
**Branch CI state:** docs-only cycle; no CI gate applies

β received the dispatch with `status: review-ready` in
`.cdd/unreleased/345/self-coherence.md` on `origin/cycle/345`. The
review-readiness section named base SHA 347a5e65 (matching current
origin/main at review time) and impl SHA b268a385. All 14 pre-review gate
rows in self-coherence.md were checked and passed before β began the review.

## Narrowing Pattern

**Rounds:** 1 (single-round approval)

R1 was a clean first-round approval with no findings. All six ACs satisfied
mechanically and by judgment inspection. The self-coherence.md was thorough:
oracle outputs were recorded, every AC had evidence, known debt (AC5 γ
obligation) was explicitly named. The pre-review gate table was complete.

No narrowing required — α delivered a coherent, complete, well-documented
docs-only cycle.

## Merge Evidence

- **Merge commit:** `9513362a89b1e11821ea90bdb61091557efcd3ac` on `main`
- **Branch:** `cycle/345` merged into `main` via `--no-ff`
- **Closes #345** in merge commit message
- **Disconnect:** merge commit is the disconnect signal per `release/SKILL.md §2.5b` (docs-only cycle; no tag/version bump)
- **β identity:** `beta@cdd.cnos` on review commit `7fcf71ba` and merge commit `9513362a`
- **pre-merge gate:**
  - Row 1 (identity): `git config user.email` = `beta@cdd.cnos` ✓
  - Row 2 (canonical-skill freshness): origin/main re-fetched synchronously before merge; confirmed at 347a5e65 ✓
  - Row 3 (merge test): collapsed — purely textual/docs cycle; no new runtime or schema contract surface shipped ✓

## β-Side Findings

No review findings. All ACs met in R1.

**Observations (factual, no dispositions):**

1. **AC oracle completeness.** The self-coherence.md recorded oracle outputs
   (wc -l, rg hits, word counts) alongside the evidence claims. This made
   mechanical verification fast and reproducible. The oracle-output-in-artifact
   pattern was effective for a docs-only cycle.

2. **Issue AC6 "four mappings" wording.** AC6 positive in the issue body reads
   "§5 sketches the four mappings (α-prose, β-clarity, γ-cycle, δ-pipeline,
   ε-iteration)" — the parenthetical lists five items despite the word "four."
   ROLES.md §5 correctly includes all five role mappings (α/β/γ/δ/ε). The
   implementation is correct; the "four" in the issue is a textual slip. This
   caused zero friction but is observable.

3. **"scope-escalation" as new term.** ROLES.md introduces "scope-escalation"
   as a term in §8. The term is new to the cdd skill corpus (not in prior
   SKILL.md files before this cycle). It is defined in §8 and used only in
   artifacts that are themselves new in this cycle (epsilon/SKILL.md, CDD.md
   pointer). The term is internally consistent and the concept traces to the
   role structure implicit in CDD.md §1.5. No drift detected, but the term's
   novelty is worth noting for the PRA.

4. **Single-round docs-only convergence.** α's pre-review gate checklist (14
   rows) was complete and accurate. The cycle is consistent with the pattern
   of well-gated docs-only cycles converging in a single round.
