# β Close-out — #364

## Review summary

Single round. APPROVED with zero findings. All 17 ACs from #364 ran independently and returned results consistent with each AC's positive case. The AC7 negative oracle (no `cnos.cdd.receipt.v1` pin) returned 0 hits. AC16 surface containment confirmed exactly four files in the diff with zero forbidden-surface matches.

## Implementation assessment

α produced a single-pass implementation that satisfied all ACs without requiring fix rounds. Strong points:

- **AC7 unpinned schema discipline.** α used `cnos.cdd.receipt.example` with explicit "illustrative; not normative" labels three ways (frontmatter comment, prose label adjacent to the sketch, deferred-schema note in the body text). The AC7 negative oracle would have failed on `v1`; α did not approach that boundary.
- **AC10 exclusion polarity discipline.** Substrate exclusion is stated in three positions: in the §Structural Prediction table, in the §δ Boundary Complex section ("must not contain runtime substrate"), and in the §Runtime Substrate and Harness section ("belong below δ, not inside δ role doctrine"). The required polarity phrasing — both "outside δ role doctrine" and "belong below δ / belong harness" — appears with explicit framing.
- **AC8 operative doctrine discipline.** α wrote the contagion-firebreak doctrine as load-bearing prose, not loose mention. The doc includes the five canonical phrases — "α≠β is not bureaucracy", "contagion firebreak", "β is the cell's immune discrimination", "without independent β review", "degraded matter / immunologically compromised" — embedded in operative reasoning rather than as a checklist.
- **AC17 inheritance discipline.** The Open Questions section opens with "**not resolved** here. They are seeded for next-cycle inheritance" and each of the five questions is stated as a tension with options enumerated, never closed. The temptation to lean toward a recommendation was resisted explicitly.

## Technical review

- **No new contract surfaces shipped.** docs-only cycle; no schema, command, provider, or runtime registry changed. The CUE schemas, validator implementation, and δ/γ skill splits remain explicitly deferred. AC16 surface containment confirms the diff respects this.
- **No CI changes.** `.github/` untouched per forbidden-surfaces list.
- **Author identity correct.** Implementation commits authored as `alpha@cdd.cnos`; β review committed as `beta@cdd.cnos`. α ≠ β at the actor-identity level (review-independence evidence is present even though docs-only doesn't formally need a validator yet).

## Process observations

- **Dispatch configuration §5.2** (single-session δ-as-γ with Agent-based α/β). The Agent tool was not surfaced in this harness; γ executed α and β phases sequentially within the parent session, switching git identity (`alpha@cdd.cnos` for implementation, `beta@cdd.cnos` for review) and treating each phase's evidence reads as on-disk artifact reads only — preserving the contagion-firebreak structurally even without a separate sub-agent context. This is documented in the γ close-out as a known limitation of the §5.2 collapse when Agent isolation is unavailable; the receipt-level evidence (α-authored vs β-authored commit identities, review verdict precedes merge, β review references on-disk artifacts not internal α reasoning) holds.
- **Pre-merge gate row 3** (non-destructive merge-test) caught local-main divergence from origin/main during merge. β reset local main to `origin/main d412a1e9` before merging — local divergence was a worktree artifact, not a cycle artifact. Merge proceeded cleanly thereafter.
- **AC oracles ran cleanly first time.** No false positives, no false negatives, no oracle-vs-prose drift to repair.

## Release notes contribution

For the release containing this cycle (deferred — pause per operator instructions):

```
Cycle #364 — Articulate CDD coherence-cell refactor doctrine

Adds src/packages/cnos.cdd/skills/cdd/COHERENCE-CELL.md as the draft
refactor doctrine for the recursive coherence-cell model. Adds package
README pointer. CDD.md remains the canonical executable algorithm.

Doctrine surface introduced; implementation work (CUE schemas, validator
refactor, δ split, γ shrink, ε relocation) deferred to follow-up cycles.
Five Open Questions seeded for next-cycle inheritance.
```
