# β closeout — cycle/415

**Issue:** [cnos#415](https://github.com/usurobor/cnos/issues/415)
**Branch:** `cycle/415`
**HEAD:** `cb40e282`

## β verdict

R1 APPROVED. See [`beta-review.md`](beta-review.md) for the full per-AC verdict + judgment-axis findings.

## Rounds

- R1: APPROVE — all 9 ACs PASS; J1–J4 confirmed; no findings of severity ≥ C.

Total review rounds: 1 (≤ 2 threshold per cnos.cds §"Cycle iteration triggers"; no trigger fired).

## Mechanical-vs-judgment ratio

100% mechanical / 0% judgment-bearing. All 9 ACs are file-presence, line-count, `cn build --check` exit, or `git diff` line-count checks. Read-checks for AC3 + AC4 are structural (section presence; frontmatter field presence) — mechanical class. Above the 20% mechanical-ratio floor; no cycle-iteration trigger fired.

## Configuration-floor compliance

β-α-collapse-on-δ. Permitted for docs-class matter per `cnos.cds/skills/cds/CDS.md §"Field 6: Actor collapse rule"`. Declared in [`beta-review.md` §"Configuration-floor declaration"](beta-review.md). No violation.

## Findings

None. No `cdd-*-gap` findings; no `protocol-compliance` findings; no `implementation-contract` findings.

## Hand-off

γ proceeds to gamma-closeout + cdd-iteration courtesy stub + INDEX.md row + push.
