# β close-out — Cycle 418

**Cycle:** [cnos#418](https://github.com/usurobor/cnos/issues/418) — Sub 4 of [cnos#404](https://github.com/usurobor/cnos/issues/404)
**Date:** 2026-05-22.

## Summary

β APPROVE-d R1 on the diff after verifying all 11 ACs PASS per α's self-coherence matrix (see `beta-review.md`). No RC rounds; no fix iterations. The cycle's intent (extract mid-flight rescue + artifact-channel rules into cnos.handoff; preserve mechanism + filenames verbatim) was met cleanly by α.

## Verdict trace

| Round | Verdict | Findings | Rationale |
|---|---|---|---|
| R1 | APPROVE | F1–F5 (all severity none, verification findings) | All 11 ACs PASS; Rule 7 conformance verified; no behavioral redesign; no out-of-scope changes |

## Release evidence

- Branch `cycle/418` builds cleanly (Markdown only; no compilation needed).
- 0 CI runs to date (the cycle is in flight; β notes that operator will merge with `Closes #418` after this cycle's close-out commits land).
- Diff scope: 12 files changed; 793 insertions / 50 deletions; 2 new files (`mid-flight/SKILL.md`, `artifact-channel/SKILL.md`).
- cnos.cdr/ diff: 0 lines.
- schemas/handoff/ + schemas/ccnf-o/: absent (verified).
- src/go/ + commands/cdd-verify/ + scripts/release.sh diff: 0 lines.
- CDD.md kernel diff: 0 lines.

## Protocol-gap count

`protocol_gap_count: 0` — no findings against the protocol this cycle. The Sub 2 / Sub 3 / Sub 4 collapse pattern (γ+α+β collapsed on δ; docs-only package migration; sequential same-session commits under per-role prefixes) operated cleanly for the third cycle in a row. The pattern is operationally stable.
