# β Close-out — cycle/410 (Sub 5 of cnos#403 wave)

**Issue:** [cnos#410](https://github.com/usurobor/cnos/issues/410)
**Verdict at merge:** APPROVED (Round 1)
**Configuration-floor caps applied:** γ-axis ≤ A-, β-axis ≤ A- per `release/SKILL.md §3.8` configuration-floor clause (β-α-collapse-on-δ active)

## Review context

This was the **largest migration sub of the cnos#403 wave** (8 surface families). β-α-collapse-on-δ was structurally appropriate given the B-lite scope ruling: no novel executable surface, canonical content moves were structurally-mirror (extraction-map destinations pre-committed), mechanical correctness verifiable from the spec.

The cycle's α produced incremental per-section commits (6 α commits total: D1+D2 / D3 / D4 / D5+D6 / D7+D8 / D10) which made the F1–F10 + §9.1 + 5-non-goals anchor-preservation discipline reviewable in chunks. The γ-scaffold's F1–F10 mapping table (issue-body parenthetical → cdd source skills) pre-emptively addressed Sub 6's re-pointing dependency; this was a structural improvement over the prior subs of the wave and worth recording for ε.

## Findings

| # | Finding | Evidence | Severity | Type | Disposition |
|---|---------|----------|----------|------|---|
| — | none | — | — | — | — |

Zero findings. Each AC carried mechanical evidence; per-section incremental commits made the diff reviewable; the F1–F10 / §9.1 / 5-non-goals anchor sets were preserved verbatim as required.

## β-level observations (non-finding)

- **The F1–F10 anchor design landed cleanly.** The issue body's parenthetical hint ("missing α/β/γ close-outs, stale `.cdd/unreleased/{N}/` after release, missing RELEASE.md, δ tag ordering, α close-out re-dispatch mechanism, PRA presence") names 6 failure modes; the dispatch spec required 10. γ-scaffold's F1–F10 mapping table extended the 6 to 10 by adding: F7 (the meta-finding that F1's re-dispatch mechanism is absent), F9 (cdd-iteration.md when triggers fired), F10 (unresolved triage). This extension is structurally honest — the 6-item parenthetical is the **failure modes named in the source**, while the 10-item F-anchor set is the **closure-gate verification checklist** the gate runs. Sub 6's re-pointing work cites the 10-item set.
- **The §Non-goals split (D7) avoided a deletion.** The existing §Non-goals at line 2175 carried sub-level scope-discipline non-goals (CDS.md authoring discipline); the 5 software-cycle non-goals are doctrine that applies to every CDS cycle. The split preserves the existing content as `### Sub-level non-goals` and adds the new content as `### Software-cycle non-goals` — both discoverable under the umbrella `## Non-goals` heading. This pattern is reusable for any future "augment an existing section" requirement.
- **The §Large-file authoring rule is self-referential.** Its operational realization is its own usage pattern; this CDS.md document is the canonical exemplar (the section-manifest header at lines 1–2 carries the canonical `sections:` and `completed:` lists; each sub of cnos#403 incrementally appended sections via the resumption protocol). No separate skill file is needed for v0.1; if accumulated cycle history warrants a dedicated skill, that's a future cycle.

## Active skill re-evaluation

For every check β ran, the loaded skills (Tier 1a CDS authority; the cdd-side review/SKILL.md as v0.1 overlay) were adequate. No skill underspecification surfaced; no `cds-skill-gap` finding warranted.

## Post-merge β work

β authors no further artifacts (no PRA — γ writes that; no release tag — δ tags). The merge commit on main with `Closes #410` is the boundary effection per cycle; β exits.
