# β 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:** β (γ+α+β collapsed on δ)

## Verdict

**R1 APPROVE.** All 11 ACs PASS as documented in `self-coherence.md` and `beta-review.md`. No findings.

## Substantive read

- Re-verified all 11 ACs via the same grep commands α used; results match α's self-coherence claims.
- Read the diff against `origin/main @ f87e6e24` for the five modified files: changes are exactly the scope α described — no smuggled content moves, no scope creep, no CCNF kernel edits, no schema/runtime touches.
- Verified the §"Sub-skills" descriptions in cnos.handoff/skills/handoff/SKILL.md still match the per-sub-skill SKILL.md files (no content drift introduced by the v0.1-complete framing edits).
- Verified the README.md §"Status" wave-narrative correctly cites all six sub-issue numbers (cnos#415, cnos#416, cnos#417, cnos#418, cnos#419, cnos#420) in the right shipping order.
- Verified the §11 Open questions resolution narrative accurately reflects how each Q was answered during the wave.
- Verified the §9 per-row Status declarations correctly summarize what each sub did.

## Findings

**None.** No incoherence; no scope creep; no surface drift; no broken links introduced.

## Hub memory

Pattern: γ+α+β collapsed on δ; docs-only wave-closure cycle; sequential same-session commits under per-role prefixes (`γ-420:`, `α-420:`, `β-420:`); sixth consecutive cycle (#415, #416, #417, #418, #419, #420) using this pattern across the cnos#404 handoff extraction wave; operationally stable; mechanical ACs (11 of 11) made review a re-grep + diff-read; no judgment cycles required.

## Merge readiness signal

β-420 commits this closeout + `beta-review.md` after α's commit. γ-420 then commits its closeout + courtesy `cdd-iteration.md` + INDEX.md row + β-closeout (collapsed). δ merges `cycle/420` to `main` with the required `Closes #420; Closes #404` message.
