# β Closeout — Cycle #389 (β-collapsed on δ)

Actor: beta@cdd.cnos (δ-as-agent, collapsed-mode; same agent as α)

## §Mode

β-α-collapse acknowledged. The β role is performed by the same Claude Code session that ran α. Mechanical β-review is anchored in:

- `tests/cdd/test_cn_cdd_validate_receipt.sh` (independent AC oracle harness; 37/37 PASS)
- `cue vet` invocations against every fixture (verified per AC2–AC8)
- JSON Schema structural check on V's `--json` output

The cycle's own receipt (once authored post-merge for ε's stream) will declare `mode: collapsed` — the trust degradation is structural-honest, not hidden.

## §Verdict

APPROVE (round 1 of 3). One design-finding (F0 — `mode: collapsed` field) was surfaced and addressed in-cycle; no RC blockers remain.

## §Findings carried forward

- F0 addressed in-cycle (added `mode: collapsed` field handling)
- Debt items D1–D5 (per α-closeout) deferred to named future cycles

## §Closure

β-collapsed review complete. Cycle proceeds to γ closeout and merge.
