# β review — cycle/378

**Verdict:** APPROVED

**Round:** 1
**β-α-collapse acknowledged:** This review runs under §5.2 wave-mode with γ+α+β-collapsed-on-δ for skill-patch class per wave manifest precedent. `α ≠ β within a session is structurally compromised` per `operator/SKILL.md` §5.2; this is the strongest available β discipline under collapse and is named in the wave manifest's precedent permitting it for skill-patch class. The review applies AC1–AC4 mechanically and treats the cross-skill coherence check as the binding gate (cross-skill drift is exactly the α failure mode this issue itself patches against; β-on-collapse catches this with text-level grep, not judgment).
**Branch CI state:** N/A — wave manifest §wave-level invariants 1 (docs-only disconnect class); no CI workflows triggered by `src/packages/cnos.cdd/skills/cdd/*/SKILL.md` or `.cdd/unreleased/378/*.md`.
**Implementation SHA reviewed:** `64c96317` (per `self-coherence.md §Review-readiness`; current branch HEAD `942f04a7` includes one further α-internal R1.2 fix-round commit documenting the second rebase, no implementation change).
**Merge instruction:** `git merge --no-ff cycle/378` into `main` with `Closes #378`.

## §2.0.0 Contract Integrity

| Check | Result | Notes |
|---|---|---|
| Status truth preserved | yes | `self-coherence.md §Review-readiness` declares round 1, implementation SHA, base SHA, β-handoff state; no shipped/draft conflation. |
| Canonical sources/paths verified | yes | Wave manifest path `.cdd/waves/2026-05-19-protocol-hygiene/manifest.md` exists on `origin/main`; cph wave anchor references resolve to `usurobor/cph` artifacts named in the issue body's `## Source` section. |
| Scope/non-goals consistent | yes | Issue body §Non-goals (1)–(5) preserved per `self-coherence.md §Self-check`; no relocation of canonical §5.1 path; no removal of binding β-side gate; no new validator; `## Protocol exemption` not required in every wave-sub body; #375 not subsumed. |
| Constraint strata consistent | yes | Three SKILL files edited additively; no doctrine edit; CDD.md untouched. |
| Exceptions field-specific/reasoned | yes | New clause (ii) names exact discoverability paths (a)/(b); not a catch-all. |
| Path resolution base explicit | yes | All paths cited as repo-relative (e.g. `.cdd/waves/{wave-id}/manifest.md`, `.cdd/unreleased/{N}/gamma-scaffold.md`). |
| Proof shape adequate | yes | AC1–AC4 each mapped to line-level evidence in the patched skill text per `self-coherence.md §ACs`. |
| Cross-surface projections updated | yes | All three cross-referencing surfaces (review, alpha, operator) converge on identical wave-mode discoverability text; no surface left stale. |
| No witness theater / false closure | yes | The new clauses describe a recognition path β actually applies (β can mechanically check sub-issue body for wave-id citation OR master-tracking-issue sub-link); no decorative-only rule. |
| PR body matches branch files | n/a | No PR; merge-direct per wave standing permissions. |
| γ artifacts present (gamma-scaffold.md) | yes | `.cdd/unreleased/378/gamma-scaffold.md` present at `origin/cycle/378:f5ab0e35` per `git ls-tree -r origin/cycle/378 .cdd/unreleased/378/gamma-scaffold.md`. Rule 3.11b satisfied via clause (i) canonical §5.1 path. **Belt-and-suspenders observation:** the wave-manifest path also serves under the new clause (ii) — wave manifest at `.cdd/waves/2026-05-19-protocol-hygiene/manifest.md` exists on `origin/main` AND lists issue #378 in `## Issues` table at L18 (path (b) per clause (ii)). Both configurations hold; either alone satisfies. |

## Cross-skill coherence check (binding gate per cycle's own subject)

This cycle's subject — rule 3.11b discoverability under §5.2 wave-mode — IS cross-skill coherence across `review`, `alpha`, `operator`. β-collapsed-on-δ runs the binding text-level check:

**Wave-manifest path:** all three surfaces use `.cdd/waves/{wave-id}/manifest.md` verbatim (review L141, alpha L257, operator L319). PASS.

**§5.2 wave-mode terminology:** all three surfaces use `§5.2 wave-mode` (review L141, L142; alpha L257; operator L319) and cross-reference `operator/SKILL.md` §5.2. PASS.

**Discoverability paths (a)/(b):** all three surfaces describe the same two paths — (a) sub-issue body cites wave-id, (b) master tracking issue links to sub. Wording is consistent:
- review L141 (a): "the sub-issue body cites the wave by id"; (b): "the master tracking issue named by the wave manifest links to the sub-issue".
- alpha L257: "sub-issue body cites the wave-id, OR the master tracking issue named by the wave manifest links to the sub-issue".
- operator L319 (a): "the sub-issue body cites the wave by id"; (b): "the master tracking issue named by the wave manifest links to the sub-issue".
PASS.

**Cross-references between surfaces:** the chain is wave-author (operator §5.2) → α pre-check (alpha §2.6 row 15) → β gate (review §3.11b clause (ii)). Each surface names the partner:
- operator L319: cross-references `review/SKILL.md` §3.11b "Exemption discoverability".
- alpha L255, L257: cross-references `review/SKILL.md` §3.11b "Exemption discoverability" and §3.11b clause (ii).
- review L141: cross-references `operator/SKILL.md` §5.2 wave-mode and §10.2.
PASS.

**Empirical anchor:** all three surfaces cite cph cdr-refactor wave 2026-05-18; master cph#11; subs cph#12-15; the four-of-four uniform pattern; the three-distinct-β-substantive-read pattern. PASS.

**No drift detected.** The three edits are internally consistent — this is exactly the α discipline the issue body §Source observed as broken in cph (β had no canonical clause to point at; each cycle's β re-derived independently). Post-patch, β has clause (ii); α has row 15; operator has the wave-author clause. The chain holds at the text level.

## Honest-claim verification (rule 3.13)

- **(a) Reproducibility:** the cph wave anchors named in the patched text cite specific files at specific paths in `usurobor/cph`. The patched text quotes line ranges (e.g. `cph#12 beta-review.md §3.11b L133–158`). These references are sourced verbatim from the issue body's `## Source` and `## Per-sub β-side anchors` sections; the issue body is authoritative per ε's filing per `epsilon/SKILL.md` §1 protocol-MCI discipline. Not novel claims — reproductions of issue-body assertions. PASS.
- **(b) Source-of-truth alignment:** terms `γ-artifact-of-record`, `§5.2 wave-mode`, `§5.1 canonical dispatch`, `γ=δ collapse`, `wave manifest`, `wave-id`, `master tracking issue`, `sub-issue body` all trace to `operator/SKILL.md` §5.2/§10 canonical definitions or are introduced here with the cross-references. No drift between informal and normative usage. PASS.
- **(c) Wiring claims:** the cross-references between the three skills are grep-verifiable (each references the partner skill by filename + section). β-collapsed-on-δ ran the grep above. PASS.
- **(d) Gap claims:** the §Gap claim is that `review/SKILL.md` rule 3.11b was silent on §5.2 wave-mode and `alpha/SKILL.md` §2.6 had no row for γ-side artifact presence. Both verifiable by grep against `origin/main:8e118320` pre-patch — `git show origin/main:src/packages/cnos.cdd/skills/cdd/review/SKILL.md` had no clause (ii) text; `git show origin/main:src/packages/cnos.cdd/skills/cdd/alpha/SKILL.md` had 14 numbered rows in §2.6, no row 15. PASS.

## Regressions Required (D-level only)

None.

## Notes

- **Two mid-cycle rebases (R1.1, R1.2) are α-internal pre-handoff state updates per `alpha/SKILL.md` §2.6 row 1**, not β-RC fix-rounds. R1.1 absorbed a `.gitignore` chore commit on main; R1.2 absorbed parallel cycle #375's merge. Both rebases were clean (no file-level conflict); cycle #375 patched `gamma/SKILL.md` which this cycle does not touch (orthogonal axis per wave manifest §wave-level invariants 4). SHA re-stamping was applied per `alpha/SKILL.md` §2.6 SHA-citations-across-rebase + §2.3 intra-doc rules; the historical R1.1 narrative was preserved verbatim under R1.2 (describes R1.1 event accurately).
- **β-α-collapse acknowledgement** appears in header; the review treats text-level grep checks as the binding gate since α=β within session compromises judgment-level independence but not text-level checks. This is the configuration the wave manifest precedent permits for skill-patch class.
- **Self-validating cycle observation.** Cycle #378 runs under exactly the §5.2 wave-mode configuration the patch codifies. The wave manifest at `.cdd/waves/2026-05-19-protocol-hygiene/manifest.md` carries the γ-artifact-of-record duty; the sub-issue (cnos#378) is listed in the manifest's `## Issues` table (path (b) per the new clause (ii)). The patch is therefore the first instance post-cph of explicitly satisfying its own rule. The per-cycle `gamma-scaffold.md` is also authored (path (i)) as belt-and-suspenders per wave invariant #3, so both clauses (i) and (ii) hold.
- **Wave invariant cross-cycle coordination** (wave manifest §wave-level invariants 4): no file-level overlap with #375; #377 not yet merged at review time but does not touch the three surfaces here (per wave manifest's surfaces-touched table). Last-merge-wins resolution applies on #377 if it lands first; otherwise merge order is mechanical.

## Verdict

**APPROVED.** All four ACs PASS; zero findings at any severity; cross-skill coherence holds at the text level; honest-claim verification (a)–(d) PASS; no CI surface affected; wave manifest standing permissions satisfied. Merge cycle/378 into main with `Closes #378`.
