# γ close-out — Cycle 420

**Cycle:** [cnos#420](https://github.com/usurobor/cnos/issues/420) — Sub 6 of [cnos#404](https://github.com/usurobor/cnos/issues/404)
**Date:** 2026-05-22
**Role:** γ (γ+α+β collapsed on δ)
**Verdict:** Closed; ready for operator merge with `Closes #420; Closes #404`.

## Closure declaration

The cycle's deliverables are complete and verified:

- D1 — residual citation sweep: clean (0 old-path-as-canonical citations remain across cnos.cdd / cnos.cdr / cnos.cds; one stale receipt-stream citation in `.cdd/iterations/INDEX.md` header repaired in α-420).
- D2 — HANDOFF.md final pass: v0.1-complete; all 5 sub-skills under Landed; no Forthcoming.
- D3 — handoff/SKILL.md loader: all "forthcoming / Sub N pending" qualifiers dropped end-to-end.
- D4 — README.md v0.1-complete: Package Structure rewritten; Forthcoming Surfaces → Surfaces (v0.1 Landed); Status rewritten as wave-closure narrative citing all 6 sub-issues.
- D5 — extraction-map.md final-status: top-of-file wave-complete blockquote; §7 deferred-by-design; §9 v0.1-complete + per-row status; §11 all 7 open questions marked resolved.
- D6 — compatibility-stub at `cnos.cdd/skills/cdd/cross-repo/SKILL.md`: **preserved as-is** per α's rationale (external repos may still cite; backward compat preserved; stub already carries its own future-cleanup self-note from Sub 2).
- D7 — extraction-map final sweep: every numbered row §1–§9 carries an explicit Status field.

## Wave-closure significance

This cycle closes the **cnos#404 handoff extraction wave**. With merge:

- **All 5 handoff sub-skills landed** at canonical `cnos.handoff/skills/handoff/{cross-repo,dispatch,mid-flight,artifact-channel,receipt-stream}/SKILL.md`.
- **cnos.handoff v0.1 ships** as the fourth coherence-cell-shaped package (peer of cnos.cdd, cnos.cdr, cnos.cds).
- **cnos.cdd kernel preserved**: CDD.md byte-identical across the wave; only role-skill sections affected were dispatch-prompt / inward-membrane (Sub 3) and post-release §5.6b (Sub 5), all replaced with pointers.
- **#405 Track A gate satisfied**: CCNF-O orchestration grammar can now type dispatch-prompt + implementation-contract surfaces from their new canonical handoff home.
- **#405 Track B1** (TSC report attachment) may proceed in parallel; receipt-stream doctrine (essay's Wave 1 substrate) lives at canonical handoff path.

## Findings

No binding findings. `protocol_gap_count: 0`. Courtesy `cdd-iteration.md` stub filed per the cycle/401 convention.

## β-α-collapse-on-δ attribution

This cycle ran as γ+α+β collapsed on δ per the breadth-2026-05-12 wave-manifest precedent — the standard pattern for skill/docs-class cycles in the #404 wave. α=β remains structurally prohibited for substantive code work; the collapse is permitted here because the cycle's primary product is doctrine cleanup, not code.

## Finalization recovery note

The dispatched agent for this cycle stalled at the β→γ transition after writing alpha-closeout, self-coherence, beta-review, and beta-closeout (all complete and verifying PASS). The operator-side γ@cnos took over to write gamma-closeout (this file), cdd-iteration stub, INDEX row, the γ-420 commit, and the branch push. All α + β artifacts authored by the stalled agent are preserved verbatim and adopted; the recovery did not redo or modify any α/β work. Recorded as informational; not a finding per ε §1 (operational-substrate recovery, not protocol-gap).

## Merge instruction

```
git checkout main
git merge cycle/420 --no-ff -m "Merge cycle/420: Sub 6 of #404 — final cleanup. Closes #420; Closes #404."
git push origin main
```

Both Closes-keywords are required: `Closes #420` closes the sub; `Closes #404` closes the wave's parent tracker on the same merge commit.
