# α close-out — cycle #377

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

## Cycle summary

Designed and built `src/packages/cnos.cdd/skills/cdd/cross-repo/SKILL.md` as the canonical surface for cross-repo CDD coordination. Updated `cdd/gamma/SKILL.md §2.1+§2.7`, `cdd/post-release/SKILL.md §5.6b`, and `.cdd/iterations/cross-repo/README.md` to reference the new skill. Updated `CDD.md §"Cross-repo proposal lifecycle"` to align canonical paths with the new skill (β R1 binding finding B-2).

Two cycle phases:
- **Design phase** (`design-notes.md`): converged directional cases (a–d + sub-shapes), STATUS state machine, bundle file set, LINEAGE schema, feedback-patch format, archival rule, hat-collapse attribution. Validated retroactively against all 8 empirical anchors with zero contradictions (after R2 correction).
- **Build phase**: wrote the 643-line skill file with embedded kata, updated three referencing skills, updated README.

## α-side findings (factual observations only — γ disposes)

### F1: Issue body's "5-event vocabulary" under-read CDD.md canonical source

The issue body §"Where they diverge" #2 and the issue's non-goal "Do NOT add a new STATUS event" both assumed a 5-event vocabulary. CDD.md §"Cross-repo proposal lifecycle" actually ships 8 events. The under-read flowed through γ scaffold and α R1; β R1 caught it as binding finding B-1.

This is **honest-claim-class** finding per `cdd/post-release/SKILL.md §5.5`: the issue body claimed a 5-event vocabulary; CDD.md's 8-event list was the artifact backing reality. Without a γ-side or α-side check against CDD.md, the claim went unchallenged until β.

### F2: Legacy paths in CDD.md not surfaced by issue's impact graph

The issue body's "What exists" enumeration listed fragments in `cdd/gamma/SKILL.md §2.1, §2.7`, `cdd/post-release/SKILL.md §5.6b`, `cdd/issue/SKILL.md`, and `.cdd/iterations/cross-repo/README.md`. It did **not** list `CDD.md §"Cross-repo proposal lifecycle"` (lines 213–245), which carried the primary protocol surface — vocabulary, source-side layouts, lifecycle rules. The omission flowed into the impact graph in self-coherence.md R1; β R1 caught it as binding finding B-2.

This is **wiring-class** finding: the issue's impact graph was incomplete. A γ pre-scaffold grep for "cross-repo" in CDD.md would have surfaced the section.

### F3: Wave-mode role-collapse worked as designed

γ=δ=α=β collapsed on δ for design-and-build mode. The collapse did not enable a hidden pass — β-collapsed-on-α produced a real R1 RC verdict with two binding findings on real CDD.md contradictions. R2 fixed both findings. The collapse-acknowledgment block in self-coherence.md + beta-review.md is the audit record.

This validates wave manifest §5.2 wave-mode precedent for cycles where independent α and β would be coordination overhead.

### F4: 8 empirical anchors is a strong retroactive validator

Validating the protocol against 8 anchors (vs. the 2 named in the issue) surfaced two real-world cases the 2-anchor validation would have missed:
- `cn-sigma/agent-activate-skill` — `drafted` event + `accepted → modified` post-filing refinement
- `cn-rho/bootstrap-2026-05-19` — case (d) operator-pending shape

These observations were folded into §2.10 known protocol edge cases. The wave manifest's empirical-anchors-must-be-cited invariant was the structural mechanism that surfaced them.

## Friction log

- **None — no friction observed.** Tooling was adequate. No environment-blocked work. No re-dispatch needed. No close-out re-dispatch required (close-outs authored in same session).

## Patterns observed

- **Under-read of canonical source via fragment-only impact graph.** When an issue's impact graph enumerates surfaces by example (the visible fragments) rather than by canonical authority (CDD.md), the canonical source is at risk of being treated as if it's also a fragment. The R2 fix-round was the symptom; a γ-side rule of "for any cycle touching CDD lifecycle, the impact graph must list CDD.md as a candidate surface" would prevent it.

- **β-collapsed-on-α can catch grep-mechanical findings reliably.** B-1 and B-2 are both literal-string contradictions against canonical source — exactly the class of finding that β-collapsed-on-α can catch without independence (because the source-of-truth check is mechanical). This is good news for design-and-build mode under §5.2.

## Cycle-level engineering level reading

L5 (skill-patch level). The cycle ships skill files only — no runtime change, no CI surface change. The size of the new skill (643 lines) is large for L5 but the surface complexity is doctrine, not code.

## Authored on `cycle/377` at HEAD commit (post-merge)

Will be filled in after β R2 merge — alpha-closeout is authored before merge per `CDD.md §1.6` sequential bounded dispatch.
