# β close-out — Cycle 419

**Cycle:** [cnos#419](https://github.com/usurobor/cnos/issues/419) — Sub 5 of [cnos#404](https://github.com/usurobor/cnos/issues/404)
**Date:** 2026-05-22

## Merge evidence

β verdict: APPROVE R1 (see `.cdd/unreleased/419/beta-review.md`).

Merge: `cycle/419` → `main` with `Closes #419`. The merge will land:

- `α-419: extract cdd-iteration receipt-stream + INDEX.md aggregator doctrine into cnos.handoff + author sub-skill + repair canonical cites` (commit `4552dfba`)
- `γ-419: scaffold cycle/419 — sub 5 of #404: extract cdd-iteration receipt-stream + INDEX.md aggregator doctrine into cnos.handoff` (commit `ab5460e8`)
- `β-419: closeouts (α/β/γ) + self-coherence + β-review + cdd-iteration courtesy stub + INDEX.md row | Cycle #419 closed` (this commit)

## Release evidence

This is a docs-only cycle; no release tag. The cnos#404 wave continues to accumulate sub-skill migrations under `cnos.handoff`; release-side artifacts (CHANGELOG, RELEASE.md, version-snapshot) are not part of this cycle (the parent tracker's wave will resolve to a docs-only release once Sub 6 closes).

## Findings

None.

## Wave progression — cnos#404

| Sub | Issue | Status | Surface | Lines |
|---|---|---|---|---|
| Sub 1 | [cnos#415](https://github.com/usurobor/cnos/issues/415) | landed | package skeleton + extraction map | — |
| Sub 2 | [cnos#416](https://github.com/usurobor/cnos/issues/416) | landed | cross-repo/SKILL.md wholesale move | 644 (now 643 post-frontmatter edits) |
| Sub 3 | [cnos#417](https://github.com/usurobor/cnos/issues/417) | landed | dispatch/SKILL.md synthesis (γ§2.5 + operator§3a + delta§2) | 417 |
| Sub 4 | [cnos#418](https://github.com/usurobor/cnos/issues/418) | landed | mid-flight/SKILL.md + artifact-channel/SKILL.md (two parallel surfaces) | 348 + 361 = 709 |
| Sub 5 | [cnos#419](https://github.com/usurobor/cnos/issues/419) | **this cycle** | receipt-stream/SKILL.md (post-release §5.6b extraction) | 340 |
| Sub 6 | (forthcoming) | pending | cross-reference cleanup + close cnos#404 tracker | — |

With Sub 5 closed, **all 5 handoff sub-skills are Landed.** Sub 6 handles the remaining citation sweep across cnos.cdd / cnos.cds / cnos.cdr / docs/gamma essays + closes the cnos#404 tracker.

## Hub memory

Pattern: γ+α+β collapsed on δ; docs-only package migration; sequential same-session commits under per-role prefixes (`γ-419:`, `α-419:`, `β-419:`); fourth cycle (#416, #417, #418, #419) in a row using this pattern; operationally stable. Pattern continues to apply for Sub 6 dispatch.
