# β close-out — cycle/401 (Phase 6 of cnos#366)

**Reviewer:** β-collapsed-on-δ (per δ contract).
**Verdict:** R1 APPROVED.
**Rounds:** 1 (no fix-rounds).
**Binding findings:** 0.
**Non-blocking observations:** 5 (recorded in `beta-review.md`).

## Review scope

α delivered six file edits + two cycle artifacts (γ scaffold, design-notes, self-coherence, β-review) implementing the Phase 6 ε upscope per the δ-pinned implementation contract. β-collapsed-on-δ review covered:

- AC1–AC7 mechanical oracle checks.
- β-rigor on AC1 (generic surface declares ε generically without CDD-normative privilege), AC5 (cdr/epsilon post-#395 actually cites the new generic surface; no duplication), AC6 (existing cdd-iteration.md files validate).
- Surface containment per δ contract.
- Implementation-contract conformance per #393 Rule 7.

## Verdict

**R1 APPROVED — no fix-round required.**

All seven ACs PASS:

- **AC1** — ROLES.md §4b exists at line 265; declares ε in seven instantiation-agnostic subsections; cdd and cdr appear only as labeled examples of the generic pattern.
- **AC2** — cdd/epsilon/SKILL.md has 6 hits on the four `cdd-*-gap` class names; 143 lines; cites ROLES.md §4b in 5 places; substantive content is now strictly CDD-instantiation-specific.
- **AC3** — post-release/SKILL.md §5.6b states "Cadence rule: cdd-iteration.md required only when protocol_gap_count > 0"; cites ROLES.md §4b.4 and cdd/epsilon/SKILL.md §1. Four-way drift closed.
- **AC4** — `cue vet -c` passes on valid generic fixture; fails on mismatched-count and mismatched-refs fixtures. Schema-unchanged from cycle #388.
- **AC5** — cdr/epsilon's opening pointer retargeted from `cnos.cdd/skills/cdd/epsilon/SKILL.md` to `ROLES.md §4b`; 0 hits on the old target string; 2 hits on the new target string.
- **AC6** — sample of existing cdd-iteration.md files (4 sampled, including empty-findings) remain valid markdown; backward-compat clause preserves their validity; no schema-side change.
- **AC7** — ROLES.md §4b is at stable citable location; Phase 7's CDD.md rewrite can cite the path without it moving.

## β observations (non-blocking)

1. **§4b.3 forward-binds to cdr per-overlay class names.** Acceptable: forward-binding is the example-of-the-pattern shape, not normative duplication. The class names live canonically in cdr/epsilon/SKILL.md §1.
2. **Cross-reference path verified.** `../../../../../../ROLES.md` from `src/packages/cnos.cdd/skills/cdd/{epsilon,post-release,activation,gamma}/SKILL.md` resolves correctly to repo-root.
3. **cdr/epsilon §1 cadence sentence updated beyond strict δ contract.** Acceptable: the update is one sentence; necessary for internal consistency with the header pointer that claims inheritance of the generic cadence rule.
4. **activation §22 severity scale + auto-spawn MCA trigger preserved.** Acceptable: the edit was confined to the lead paragraph; the substantive activation-skill features survive intact.
5. **gamma/SKILL.md §2.10 row 14 is a single-line edit.** Acceptable: scope does not overlap with Phase 5 (broader gamma/SKILL.md territory).

No binding findings. No fix-round. β-collapse-on-δ review complete.

## Trigger assessment (per gamma/SKILL.md §2.8 table)

| Trigger | Fired? | β note |
|---|---|---|
| Review churn (rounds > 2) | **No** | R1 APPROVED. |
| Mechanical overload (>20% AND findings ≥10) | **No** | 0 binding findings. |
| Avoidable tooling / environment failure | **No** | `cue` available and ran cleanly. |
| CI red on merge commit | **N/A** | Pre-merge. |
| Loaded skill failed to prevent a finding | **No** | No findings. |

No §9.1 triggers fired.

## Disposition

The cycle is ready for γ close-out, cdd-iteration.md, and merge to main.
