# γ close-out — cycle/378

**Cycle:** #378 — "cdd: rule 3.11b discoverability under §5.2 wave-mode (wave-manifest as γ-artifact-of-record; cdd-protocol-gap)"
**Wave:** `2026-05-19-protocol-hygiene` (per wave manifest at `.cdd/waves/2026-05-19-protocol-hygiene/manifest.md`)
**Mode:** §5.2 wave-mode; γ+α+β-collapsed-on-δ for skill-patch class per wave manifest precedent.
**Verdict:** β R1 APPROVED at `8e40d9af`.
**Rounds:** 1 β round (APPROVED first pass); 2 α-internal rebase fix-rounds (R1.1, R1.2) — not β-RC.

## Cycle summary

Three coordinated skill-patch edits to `review/SKILL.md`, `alpha/SKILL.md`, `operator/SKILL.md` close the rule 3.11b discoverability gap under §5.2 wave-mode. Empirical anchor cited across all three patched surfaces: cph cdr-refactor wave 2026-05-18 (master cph#11; subs cph#12-15) — four-of-four sub-uniform configuration with three distinct β substantive-reads of the same wave-manifest-as-γ-artifact configuration.

## Configuration declared (per `operator/SKILL.md` §5.2)

- **Dispatch:** §5.2 wave-mode (γ=δ collapse permitted per wave manifest).
- **Further super-collapse:** γ+α+β-collapsed-on-δ for this single skill-patch cycle. `α ≠ β within a session is structurally compromised` per `operator/SKILL.md` §5.2 — named in `self-coherence.md §Gap`, `beta-review.md` header, and this close-out.
- **Acceptance for skill-patch class:** wave manifest precedent permits it (manifest §wave-level invariants — wave dispatches three skill-patch-class cycles; bar for super-collapse safety is text-level coherence, which β-on-collapse can satisfy). Skill-patch class is the right scope; design-and-build class (#377) should not super-collapse.
- **Grading floor:** per `release/SKILL.md` §3.8 configuration-floor clause for δ=γ collapse, γ < A. This cycle's super-collapse extends the floor further; γ accepts the grade implication for the wave-iteration record.

## Deferred outputs to operator (δ-external)

- **Merge cycle/378 into main:** wave standing permissions grant this; mechanical `git merge --no-ff cycle/378` per β merge instruction. No tag/release (docs-only disconnect class per wave manifest).
- **Branch delete after merge:** wave standing permissions grant this; delete `cycle/378` locally and on origin.

## Cross-cycle coordination (per wave manifest §wave-level invariants 4)

- **#375 merged at `8e118320` mid-cycle.** #378 rebased onto post-#375 main at R1.2 (clean, no conflict — #375 patched `gamma/SKILL.md` §2.5 Step 3b only). Mechanical merge order: #375 first, #378 second.
- **#377 not yet landed at γ close-out.** #377 touches `cross-repo/SKILL.md`, `gamma/SKILL.md`, `post-release/SKILL.md` — no overlap with #378's surfaces. If #377 lands before #378's merge, #378 will need a third rebase; the same clean-rebase path should apply (no expected file overlap). γ-as-δ will check `git diff --stat origin/main..HEAD` immediately before merge.

## Wave-iteration findings (for `.cdd/iterations/wave-2026-05-19-protocol-hygiene.md` per `cdd/post-release/SKILL.md` §5.6b)

- **γ-axis:** self-validating cycle pattern. #378's patch codifies the rule under which #378 itself runs. Wave manifest's `## Issues` table populated with sub-issue links discharged path (b) of the new clause by construction. This is the canonical wave-manifest authoring shape for future §5.2 waves.
- **β-axis:** β-α-collapse with text-level grep gate worked for skill-patch class. The cross-skill coherence check was the binding gate; it caught zero drift because α applied identical phrasing across the three edits intentionally as α discipline. The pattern is reproducible — future β-collapse reviewers should treat cross-skill coherence as the binding gate when the cycle subject is itself cross-skill coherence.
- **α-axis:** two mid-cycle rebases (R1.1, R1.2) handled cleanly via existing `alpha/SKILL.md` §2.6 row 1 + §2.6 SHA-citations-across-rebase + §2.3 intra-doc rules. No new α gap surfaced; the existing rules scale to multi-rebase scenarios. Rebase-churn is structural under §5.2 wave-mode with parallel cycles; wave authors should expect it.
- **Pattern: belt-and-suspenders γ-artifact authoring under wave-mode.** Cycle authored both `.cdd/unreleased/378/gamma-scaffold.md` (path (i)) AND ensured wave-manifest discoverability link (path (b)). Both clauses (i) and (ii) of rule 3.11b held. For future wave-internal subs, the per-cycle scaffold is cheap and recommended (reduces ambiguity for any β not familiar with §5.2); wave-mode discoverability remains the canonical path that does not require per-sub scaffolds.

## ε iteration target

Findings consolidate to `.cdd/iterations/wave-2026-05-19-protocol-hygiene.md` per wave manifest §ε iteration target.

## Closure declaration

Cycle #378 closure ready. β verdict APPROVED; close-outs (α, β, γ) authored on cycle branch; merge pending δ-as-γ action per wave standing permissions. No follow-on cnos issues required from this cycle.
