# γ close-out — cycle #377

**Issue:** #377 — design(cdd): codify cross-repo coordination protocol
**Branch:** `cycle/377`
**γ identity:** gamma-collapsed-on-δ@cnos.cdd.cnos (role-collapse acknowledged in gamma-scaffold.md)

## Cycle summary

Codified cross-repo CDD coordination protocol in `src/packages/cnos.cdd/skills/cdd/cross-repo/SKILL.md`. The new skill names four directional cases (inbound proposal 1:1/master+sub; outbound iteration trace; bilateral iteration; operator-pending bundle with three sub-shapes), one canonical path (`.cdd/iterations/cross-repo/{counterpart-repo}/{slug}/`), the 8-event STATUS state machine (aligned with CDD.md canonical source), bundle file set per case, LINEAGE.md schema per case, feedback-patch format, asymmetric bundle archival rule, and hat-collapse attribution form.

Three existing skills now reference the new surface (gamma §2.1+§2.7, post-release §5.6b, CDD.md §"Cross-repo proposal lifecycle"); `.cdd/iterations/cross-repo/README.md` aligned bundle-state phases with the canonical state machine. `cdd/issue/SKILL.md` `## Source Proposal` block unchanged (per AC6).

Protocol validated retroactively against 8 empirical anchors with zero contradictions.

## Close-out triage table

| Finding | Source | Type | Disposition | Artifact / commit |
|---------|--------|------|-------------|-------------------|
| F1 (α): Issue body's 5-event vocabulary under-read CDD.md | α-closeout | honest-claim | **patch-landed** (R2 fix landed in this cycle) | commit `5a42a04`; CDD.md + cross-repo skill + design-notes aligned to 8 events |
| F2 (α): Legacy paths in CDD.md not surfaced by issue's impact graph | α-closeout | wiring | **patch-landed** (R2 fix landed in this cycle) | commit `5a42a04`; CDD.md updated to canonical path; legacy paths removed |
| F3 (α): Wave-mode role-collapse worked as designed for this cycle's shape | α-closeout | observation | **drop** (validation, not a finding) | n/a |
| F4 (α): 8-anchor validation surfaced 5 protocol observations 2-anchor would miss | α-closeout | observation | **drop** (validation of wave-manifest invariant) | n/a |
| F1 (β): CDD.md was canonical authority all along — γ impact-graph gap | β-closeout | wiring / honest-claim | **next-MCA candidate** — γ-side rule "for any cycle touching CDD lifecycle, impact graph MUST list CDD.md as candidate surface". Surface to wave-2026-05-19 ε iteration. | filed to wave ε iteration (see `cdd-iteration.md` below) |
| F2 (β): β-α-collapse caught grep-mechanical findings reliably; would not catch judgment-class | β-closeout | observation | **drop** (validation of role-collapse boundaries) | n/a |
| F3 (β): Cross-cycle merge integration was clean | β-closeout | observation | **drop** (validation of parallel wave dispatch) | n/a |
| F4 (β): AC3 retroactive-validation discipline produced highest-information output | β-closeout | observation | **drop** (validation of empirical-anchors invariant) | n/a |
| N-1 (β R1): Master-close `landed` event format lacks release-version field | β-review R1 | judgment | **no-patch** — non-blocking; format extension is future cycle's scope | known debt in self-coherence.md |
| N-2 (β R1): `## Source Proposal` block placeholder convention not surfaced | β-review R1 | judgment | **no-patch** — out of cycle scope (AC6 forbids `issue/SKILL.md` change); future iteration may extend | known debt in self-coherence.md |
| N-3 (β R1): `drafted` term collision between STATUS event and LINEAGE phase | β-review R1 | judgment | **patch-landed** — distinguished in §2.4 + §2.5/§3.9 of R2 skill text | commit `5a42a04` |

Silence is not triage — every finding has a disposition.

## §9.1 trigger assessment

| Trigger | Fire condition | Fired? | γ disposition |
|---|---|---|---|
| Review churn | review rounds > 2 | **No** (rounds = 2) | At target. |
| Mechanical overload | mechanical ratio > 20% AND findings ≥ 10 | **No** | Mechanical ratio = 100% (both binding findings grep-mechanical); total findings count = 5 (2 binding + 3 non-binding), below 10-finding threshold. Note ratio without action per `gamma/SKILL.md §2.8`. |
| Avoidable tooling / environment failure | environment blocked the cycle | **No** | No tooling friction. |
| Loaded-skill miss | a loaded skill should have prevented a finding | **Borderline — Yes for F1/B1.** | `cdd/issue/SKILL.md` arguably should have required issue authors to grep canonical source when authoring an impact graph; the under-read of CDD.md's 8-event vocabulary is exactly the failure that better γ-side gap-naming discipline would have caught. **Disposition: next-MCA candidate** (F1-β above); filed to wave ε iteration for γ-side rule. |

**Cycle iteration entry required:** YES — loaded-skill miss trigger fired (γ-side gap-naming discipline). Recorded in `cdd-iteration.md`.

## Cycle iteration

**Trigger:** loaded-skill miss (γ-side gap-naming discipline allowed an under-read of CDD.md as the canonical source for the new skill's vocabulary).

**Root cause:** γ scaffold §"§Peer enumeration at scaffold time" required grep + ls for the cycle's directly-named surfaces, but did not require grep against CDD.md for the protocol concern the cycle was addressing. The omission flowed into the issue's impact graph and α's R1 codification; β R1 caught it from canonical-source check.

**Disposition:** **next-MCA committed.** A γ-side rule extension — "When the cycle touches CDD-lifecycle doctrine (cross-repo, role lifecycle, gates, artifact contract), the §2.2a peer enumeration MUST include `rg <concern> src/packages/cnos.cdd/skills/cdd/CDD.md` and surface any matches in §Gap" — should be authored in a future cycle filed against gamma/SKILL.md §2.2a.

**Evidence:** β-review.md R1 finding B-1 + α-closeout F1 + this cycle's R1→RC→R2 fix-round.

## CDD self-coherence (this cycle)

- **α (artifact integrity):** 4/4. All required artifacts present and synced. self-coherence.md carries gap/mode/ACs/CDD Trace; design-notes.md carries the design phase; cross-repo/SKILL.md is the build product; closeouts authored.
- **β (surface agreement):** 3/4. R1 surfaced a real surface-agreement failure (vocabulary contradicted CDD.md); R2 resolved it. Score reflects that R1 caught it and R2 fixed it — 4/4 would imply no surface-agreement failure ever existed; 3/4 reflects the real fix-round.
- **γ (cycle economics):** 4/4. 2 review rounds (at target ≤2), zero superseded cycles, clean merge, all findings dispositioned.

**Weakest axis:** β. **Action:** filed as next-MCA per Cycle Iteration above — γ-side rule extension to gamma §2.2a will prevent the same class of under-read.

## Deferred outputs

- **γ-side rule extension to gamma §2.2a** — next-MCA filed for follow-on cycle. Owner: future γ. First AC: gamma §2.2a peer-enumeration MUST include `rg <concern> src/packages/cnos.cdd/skills/cdd/CDD.md` when cycle touches CDD-lifecycle doctrine. Freeze state: none (the protocol-hygiene wave continues to surface CDD-touching cycles; this rule applies to them prospectively, not retroactively).

- **`cn cross-repo` CLI surface** — deferred per issue non-goal; future cycle once protocol stability is validated across ≥1 more cross-repo cycle. Owner: TBD. First AC: TBD. Freeze state: none — defer until empirical evidence the protocol is stable.

## Hub memory

The hub-memory step is δ-side (no daily reflection / adhoc thread updates authored in this cycle session — the wave-2026-05-19 ε iteration consolidates hub updates per wave manifest §"ε iteration target"). γ defers to wave-level ε for hub memory.

## Cross-repo trace

This cycle did not produce cross-repo patches landing in another repo. No `.cdd/iterations/cross-repo/{counterpart}/{slug}/` bundle required.

## Next-MCA commitment

**Next MCA:** wave-internal — the 2026-05-19 protocol-hygiene wave closes when all three cycles (#375, #377, #378) merge. #375 + #378 already on main; #377 (this cycle) merges next. After #377 merges:
- ε iteration consolidates wave findings into `.cdd/iterations/wave-2026-05-19-protocol-hygiene.md` per wave manifest §"ε iteration target".
- The follow-on γ-side rule extension to gamma §2.2a (cycle iteration finding above) is filed as a separate cycle issue if not folded into the wave ε iteration.

**Owner:** δ (for wave close-out) + future γ (for rule extension).

**Branch:** post-merge.

**First AC:** wave-closeout artifact exists at `.cdd/iterations/wave-2026-05-19-protocol-hygiene.md`.

**MCI frozen?** No.

**Rationale:** wave-mode protocol hygiene is a non-MCI cycle class; no MCI-MCA balance impact.

## Closure declaration

Cycle #377 closes when:
- ✅ β R2 APPROVE recorded
- ✅ All ACs PASS under R2 oracle re-runs
- ✅ Closeouts authored (this file + alpha-closeout.md + beta-closeout.md)
- (pending) merge to main with `Closes #377` convention
- (pending) branch deleted (origin/cycle/377)

**Cycle #377 closed. Next: wave-2026-05-19 ε iteration (or next operator-dispatched cycle).**
