## β reviewer-ask-list

| Axis | Score | Note |
|---|---|---|
| α (matter quality) | A- | Canonical content faithfully extracted from pre-#402 CDD.md §1.5 (Tracking) and §5 (Artifact Contract); structural framing mirrors Sub 3's §Selection function + §Development lifecycle; "Sub-X-vs-Field-Y line" pattern preserved at section bridges. Configuration-floor cap at A- per `release/SKILL.md §3.8` (β-α-collapse-on-δ for docs-class cycle). |
| β (review quality) | A- | All 10 ACs mechanically or read-check verified; per-AC oracle table present; hard rules independently verified. Configuration-floor cap at A- per the same rule. |
| γ (coordination quality) | A | Scaffold authored with full sourcing map (pre-#402 CDD.md pin commit + section anchors), peer enumeration recorded, dispatch decision (skip optional thin overlays) justified explicitly. γ-axis not collapsed; full A. |

**Weakest-axis diagnosis:** α and β both at A- per the structural cap, not per any substantive deficiency. No fix-round needed.

**Concrete patch suggestions:** none. The implementation is canonical and matches the issue body, the γ scaffold's source mining map, and the extraction-map row commitments.

**Iterate-or-converge verdict:** **CONVERGE.** R1 APPROVED.

## β-side findings

### Finding B1 (informational — not binding)

**Class:** observation about §Polling primitives wake-up section
**Severity:** informational (not A/B/C/D — purely descriptive)

§Polling primitives → wake-up mechanism mentions `Monitor` (Claude Code on the web) by name. CDS.md was generally conservative about naming runtime substrates (the Persona/Protocol/Project section names persona hubs but does not embed runtime mechanics). Mentioning `Monitor` is consistent with the pre-#402 CDD.md source (which also names it as the canonical wake-up substrate on Claude Code on the web) and is necessary for the canonical statement to be operationally legible. The alternative — "any environment that provides transition-line wake-up" — would be more abstract but less actionable. β verdict: leave as-is; the `Monitor` reference is the same engineering-substrate-specificity the pre-#402 CDD carried, and CDS.md's project-binding section permits naming runtime tools as long as the doctrinal shape is portable (operators may bind a different wake-up mechanism in their `<project>/.cds/POLICY.md`).

### Finding B2 (informational — not binding)

**Class:** observation about §Cross-repo proposals scope
**Severity:** informational

§Cross-repo proposals codifies the full 8-event vocabulary + transition graph + emitter rules + bundle-state phase mapping + master/sub `landed` rule + direct-acceptance path. This is substantially deeper than a "thin extract" might minimally require — but the issue body's D1 description for §Cross-repo proposals explicitly names "proposal lifecycle (drafted/submitted/accepted/modified/rejected/landed/withdrawn/revised) + STATUS state machine" as the canonical content to host in CDS.md. β verdict: the depth is contract-pinned, not improvisation. The same content exists in `cross-repo/SKILL.md §2.3` as the operational realization; CDS.md's version is the canonical statement, and the cdd-side skill is cited as the operational expansion. Pointers, not duplication — but the canonical statement itself must carry the vocabulary.

### Finding B3 (informational — not binding)

**Class:** observation about §Location matrix legacy/scratch column
**Severity:** informational

The §Location matrix table preserves the pre-#402 "Noncanonical / legacy / scratch" column verbatim (warn-only paths for pre-#283 aggregate `CLOSE-OUT.md` forms; etc.). β verdict: this is the right call — the warn-only paths are still active in the empirical anchor (cnos's `.cdd/releases/` directory carries some of these pre-#283 forms); preserving the legacy column makes the canonical statement honest about what verifiers continue to tolerate, rather than presenting a clean-slate location matrix that the project binding doesn't actually use yet.

## β-side observations on the cycle shape (non-binding)

- The β-α-collapse-on-δ pattern continues to serve docs-class cycles well. The Sub 3 cycle (#408) ran the same pattern and converged R1; this cycle (#409) follows the precedent without friction. The configuration-floor cap at A- on α and β axes is the structural acknowledgment that the collapsed-actor configuration trades some review-independence for cycle velocity on canonical-content moves.
- The pre-#402 CDD.md source pin (`8f06a606^`) is the right authority chain. Every rule statement in the new CDS.md sections can be traced back to a specific pre-#402 CDD.md sub-section, with CDD-vocabulary minimally re-cast as CDS-vocabulary (the "CDD Trace" → "CDS Trace" rename is the only substantive name change; format is verbatim).
- The `.cdd/` → `.cds/` re-rooting documentation in both §Cycle-state evidence and §Location matrix is consistent — both surfaces note "current `.cdd/` form / destination `.cds/` form" without performing the rename. AC6 mechanical check confirms no rename ops in the diff. This is the cleanest possible reading of the hard rule: document the planned move; don't perform it.

## Merge instruction

On verdict APPROVED (R1), β authors `beta-closeout.md`, γ authors `gamma-closeout.md` and `cdd-iteration.md` (courtesy stub — `protocol_gap_count: 0`), then γ pushes `cycle/409` to origin. **β does NOT execute the merge to main itself** per the issue body's "Do NOT merge to main yourself" directive — the operator (the user) merges. β's role here is to close the review with the verdict.
