# α 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)"
**Mode:** §5.2 wave-mode; γ+α+β-collapsed-on-δ for skill-patch class.
**Rounds:** β R1 APPROVED; two α-internal rebase fix-rounds (R1.1, R1.2).

## Summary

Three coordinated skill-patch edits extend rule 3.11b to recognize the wave-manifest at `.cdd/waves/{wave-id}/manifest.md` as a valid γ-artifact-of-record under §5.2 wave-mode, with the sub-issue ↔ wave-manifest discoverability link auditable via (a) sub-issue body wave-id citation OR (b) master tracking issue → sub-issue link. Surfaces patched: `review/SKILL.md` §3.11b (clause (ii) + recovery path (c)); `alpha/SKILL.md` §2.6 row 15; `operator/SKILL.md` §5.2 wave-manifest-as-γ-artifact clause. Empirical anchor: cph cdr-refactor wave 2026-05-18.

## Friction log

- **Two mid-cycle rebases (R1.1, R1.2)** triggered by `origin/main` advance during α work. R1.1 absorbed a `.gitignore` chore commit; R1.2 absorbed parallel cycle #375's merge. Both rebases were clean. `alpha/SKILL.md` §2.6 row 1 (transient row) + §2.6 SHA-citations-across-rebase + §2.3 intra-doc rules covered the handling without protocol gap.
- **SHA re-stamping discipline at scale.** R1.1 invalidated 5+ SHA citation sites; R1.2 invalidated another batch. The §2.3 grep-every-occurrence rule + the §2.6 SHA-citations-across-rebase paragraph were sufficient. The R1.2 fix retained the R1.1 narrative verbatim (R1.1 SHAs are accurate descriptions of *the R1.1 event* even though those R1.1 post-rebase SHAs no longer exist after R1.2) — this read-as-history-not-as-pointer pattern is what kept the artifact under control across two rebase rounds.
- **Self-validating cycle.** Cycle #378 runs under exactly the §5.2 wave-mode configuration the patch codifies. Wave manifest listed #378 in `## Issues` table (path (b) per the new clause); this cycle is the first instance post-cph of explicitly satisfying its own rule.
- **No-conflict cross-cycle coordination** worked as wave manifest §wave-level invariants 4 anticipates — cycle #375 patched `gamma/SKILL.md` §2.5 Step 3b; cycle #378 patched `review/`, `alpha/`, `operator/`. No file-level overlap; mechanical merge order.

## Observations

- **Pattern: rebase churn is structural under §5.2 wave-mode with three parallel cycles dispatched concurrently.** Two rebases in one cycle is within expected behavior, not friction. Surfaces affected: `alpha/SKILL.md` §2.6 row 1 + §2.6 SHA-citations-across-rebase + §2.3 intra-doc rules — all held. No new gap surfaced.
- **Pattern: belt-and-suspenders γ-artifact under wave-mode.** This cycle authored both `.cdd/unreleased/378/gamma-scaffold.md` (path (i)) AND ensured wave-manifest discoverability link (path (b) via wave manifest's `## Issues` table). Both clauses (i) and (ii) of rule 3.11b held; either alone would have satisfied. The per-cycle scaffold is cheap (66 lines) and reduces ambiguity for any β not familiar with §5.2; wave-mode discoverability remains the canonical path for wave-internal subs.
- **Pattern: cross-skill coherence as α discipline.** The three edits used identical phrasing for the wave-mode discoverability path. Drift across files is the exact failure mode this issue itself patches against (in cph, β re-derived independently per sub). Post-patch β-collapsed-on-δ verified the chain operator §5.2 → alpha §2.6 → review §3.11b holds. Same class as `alpha/SKILL.md` §2.3 skill-class-peer enumeration.
- **Pattern: §5.2 wave-mode + γ+α+β-on-δ super-collapse is workable for skill-patch class.** Wave manifest precedent permitted it; the β-collapsed-on-δ review applied text-level grep checks as binding gate, which preserved the structural property β-on-collapse can satisfy (text-level coherence) while accepting the property it cannot (judgment-level independence). Skill-patch class is the right scope for this super-collapse; design-and-build class (e.g. wave #377) should not super-collapse.

## Engineering-level reading

None — pure skill-patch cycle. No code, no schema, no runtime, no CI. All edits are docs-only disconnect class per wave manifest §wave-level invariants 1.

## Voice note

This close-out reports factual observations and patterns only per `alpha/SKILL.md` §2.8. Triage of any pattern into follow-on issues belongs to γ.
