# Beta Close-Out — Cycle #335

## Review context

Cycle #335 retroactively closed cycles #331 and #333 (both partial-protocol releases that had merged without close-out artifacts). The retro cycle's own artifacts initially repeated the protocol-skip pattern by self-asserting "α-only docs-only — no β session." β review was conducted as a cross-repo audit from `usurobor/tsc` rather than as an in-cycle β session, because no β agent was dispatched in cycle #335's loop.

The audit drove an R1 → R2 fix-round on PR #337 that resolved 6 binding findings (F1–F6) and surfaced one B-level observation (F7) acknowledged as known debt for a follow-on rubric refinement.

## Round-by-round narrative

| Round | β Verdict | Findings | α response | β re-verdict |
|-------|-----------|----------|------------|--------------|
| R1 | REQUEST CHANGES | F1 D, F2 D, F3 C, F4 C, F5 B, F6 B | Fix commit `688856f` addressing all 6 | → R2 |
| R2 | APPROVED | F7 B (acknowledged debt) | Disposition: follow-on cycle | merged |

R1 → R2 resolution was tight (all 6 findings closed in one fix commit; no F* re-emerged in R2). The narrowing pattern is consistent with cycles where α/β share the spec context — rule 3.13 was just-introduced by cycle #331 and was the dominant lens for the audit.

## Merge evidence

- **PR:** `usurobor/cnos#337`
- **Branch:** `cycle/335-cdd-retro-closeout`
- **Final commit:** `688856f` (R1 fix-round) on top of `1ec471d` (initial submission)
- **Merge:** confirmed by operator post-audit; β verdict was APPROVED at R2.
- **Cycle dir:** `.cdd/releases/docs/2026-05-09/335/` (already at canonical post-§2.5b path; cycle pre-applied the move in its commits).

## β-side factual observations

Voice rule per `cdd/beta/SKILL.md`: factual observations only. No dispositions; γ owns triage.

**O1 — Cross-repo β audit pattern was novel.** This cycle is the first cnos cycle whose β review was conducted from `usurobor/tsc` rather than on the cycle's own branch. The pattern was operator-initiated ("have TSC review #337"). The review identity is git-observable in the audit record (see `beta-review.md` § Review identity disclosure). This is not standard cnos β procedure; whether to formalize as an alternate β path or treat as one-off operator override is γ's decision.

**O2 — The audit exposed rule 3.13's recursive value.** The cycle that introduced rule 3.13 (cnos #331 patch 1) was held to it on its own follow-up (#335). Three of the six R1 findings (F1, F2, F4) are honest-claim class violations caught by rule 3.13. The rule is producing review value the moment it lands. Useful data point for the cnos-cdd review skill's evidence-of-effectiveness ledger.

**O3 — Operator override path works when honestly declared.** The cycle #335 friction log (post-fix) names timeout, names operator-completion of 3/9 ACs, names the override per `operator/SKILL.md` §4. The override is honest, not hidden as protocol compliance. This is the pattern §4 was designed to support.

**O4 — Friction log surfaced a tooling-class finding.** The first dispatch attempt failed because `--output-format stream-json` requires `--verbose` with `-p`. This is an environmental constraint that the cdd skill bundle should know about. cycle #333 already landed `--verbose` in `operator/SKILL.md`; the friction log explicitly references this and validates the patch was correct.

**O5 — Grade drift across artifacts (F7).** The same cycle's grade is C+ in one artifact (gamma-closeout, computed via §3.8 math) and C− in three others (PRA, CHANGELOG, alpha-closeout). The drift surfaces a rubric design gap: closure-gate failure forces `<C` disposition but the per-axis math doesn't bottom out at `<C`. Operator and β agreed F7 deserves a small follow-on cycle on the rubric.

**O6 — The `usurobor/tsc:.cdd/iterations/cross-repo/cnos/cdd-supercycle/` trace directory has fulfilled its purpose.** Per Step 5.6b: "lineage preserved in target repo's own `cdd-iteration.md`; cross-repo dir may be deleted thereafter." The cnos-side bilateral mirror at `.cdd/iterations/cross-repo/tsc/cdd-supercycle/LINEAGE.md` is now in place (committed by cycle #335). Tsc-side trace is operationally redundant.

## Findings landed by this audit

The 6 R1 findings + 1 R2 finding are recorded in `beta-review.md` (this cycle dir). They are also material for cnos-side cycle-iteration reflection:

- F1 (3.13b): authority drift between issue mode declaration and §2.5b. Resolved.
- F2 (3.13a): missing friction log violated reproducibility. Resolved.
- F3 (§3.8): inflated α grade. Resolved.
- F4 (presupposition): pre-asserted β: N/A. Resolved.
- F5 (contract): beta-review.md was hybrid stub. Resolved.
- F6 (Step 5.6b): mixed dispositions in cdd-iteration.md F1. Resolved.
- F7 (3.13b, acknowledged): grade drift across artifacts; follow-on cycle.

## Cross-repo footprint

- **cnos-side artifacts:** `.cdd/releases/docs/2026-05-09/335/{self-coherence, beta-review (replaced by this), alpha-closeout, beta-closeout (this), gamma-closeout, cdd-iteration}.md`
- **cnos-side cross-repo mirror:** `.cdd/iterations/cross-repo/tsc/cdd-supercycle/LINEAGE.md` (committed by cycle #335)
- **tsc-side cross-repo source:** `.cdd/iterations/cross-repo/cnos/cdd-supercycle/LINEAGE.md` at commit `772ddc0` — now redundant per O6; deleted in this courier commit
- **β review record (cnos-side, post-audit):** this file + companion `beta-review.md`, delivered via tsc courier `courier/cnos-cycle-335-beta-completion`

## β grade

**β: B+** — review value real (R1 6 binding findings, all material; R2 1 acknowledged observation). Two friction notes:

1. The review was post-merge, not pre-merge. Standard cnos β reviews land before merge. This cycle's β path was non-standard (cross-repo audit) because no β agent was dispatched in the original loop. Honest record: this is not a clean A.

2. β identity disclosure required (see beta-review.md § Review identity disclosure). The review is conducted under tsc operator's git identity, not under canonical `beta@cdd.cnos`. The role separation is git-observable but unconventional.

Both friction notes belong in γ's PRA disposition for the next post-release assessment that revisits this cycle (if any).

## Voice rule compliance

This file follows `cdd/beta/SKILL.md` voice rule: factual observations only. No dispositions assigned to F* or O*. γ writes the disposition in `gamma-closeout.md` triage table or in the next PRA's §3 Process Learning.
