# γ close-out — cycle/409 / cnos#409

**Cycle:** Sub 4 of cnos#403 — Migrate §Coordination surfaces + §Artifact contract to CDS.md (B-lite thin extract)
**Branch:** cycle/409 (head `7e245f45` at γ close-out time; final close-out commit will advance head)
**Verdict:** APPROVED (R1) — see `beta-review.md`
**Merge instruction (forward-looking):** see operator-facing report below

## Cycle summary

This cycle landed the canonical §Coordination surfaces and §Artifact contract content into `src/packages/cnos.cds/skills/cds/CDS.md` per the B-lite thin-extract ruling. The pre-#402 CDD.md content (mined at `8f06a606^` — the parent of the CCNF-spine rewrite) carried the rules inline; this cycle moved them into CDS-owned surfaces while leaving operational realization in the existing cnos.cdd role/runtime skills as v0.1 overlays, cited from each new section's `### Operational realization` sub-heading.

The Sub 3 (cnos#408) precedent — same B-lite shape for §Selection function + §Development lifecycle — set the structural template; Sub 4 followed it without modification.

## AC verification summary

All 10 ACs PASS (see `self-coherence.md §ACs` and `beta-review.md §Per-AC oracle verification` for the mechanical/read-check evidence).

| AC | Verdict | Evidence |
|---|---|---|
| AC1 | PASS | `grep -c "^## Coordination surfaces" CDS.md` = 1 |
| AC2 | PASS | `grep -c "^## Artifact contract" CDS.md` = 1 |
| AC3 | PASS | 4 sub-headings under §Coordination surfaces |
| AC4 | PASS | 9 sub-headings under §Artifact contract |
| AC5 | PASS | 4 `### Operational realization` sub-headings (Sub 3 added 2; Sub 4 added 2) |
| AC6 | PASS | re-rooting documented in §Cycle-state evidence (3 mentions) AND §Location matrix (1 dedicated paragraph + inline destination dual-naming); no rename/move ops in `git diff origin/main..HEAD -- '.cdd/'` |
| AC7 | PASS | `git diff origin/main..HEAD -- src/packages/cnos.cdd/` empty (hard rule) |
| AC8 | PASS | `git diff origin/main..HEAD -- src/packages/cnos.cdr/` empty (hard rule) |
| AC9 | PASS | Sub 4 status added for rows 3+4 (2 lines); Sub 3 rows 1+2 preserved; +2/-0 in extraction-map.md |
| AC10 | PASS | 0 files under role-overlay dirs (`alpha,beta,gamma,delta,epsilon,operator`) |

## Close-out triage table

| Finding | Source | Class | Disposition |
|---|---|---|---|
| α1 — Ownership matrix `cdd-iteration.md` Owner annotation "(with ε review)" extends pre-#402 wording | `alpha-closeout.md §Findings` | editorial extension (not a gap) | NO-PATCH. The annotation is consistent with §Field 5 ε iteration cadence; Sub 6 (CDD.md marker cleanup) can decide whether to mirror or revert at sweep time; both are coherent. No follow-up filed. |
| α2 — §Bootstrap pre-dispatch gate paragraph mined from `gamma/SKILL.md §2.5` rather than pre-#402 CDD.md §5.1 inline | `alpha-closeout.md §Findings` | editorial decision (additive content within B-lite scope) | NO-PATCH. The rule (γ MUST author scaffold before α dispatch) is a canonical rule that belongs in the canonical home; the operational mechanics stay in `gamma/SKILL.md`. B-lite scope respected. No follow-up filed. |
| α3 — §Mid-flight clarification empirical anchor depth (cnos#391 + cnos#393) | `alpha-closeout.md §Findings` | editorial decision | NO-PATCH. Anchor list reflects post-#402 empirical evidence; Sub 7 (empirical anchor doc) will normalise anchor lists across CDS.md sections. No follow-up filed. |
| β1 — `Monitor` reference in §Polling primitives | `beta-review.md §Findings` | informational | NO-PATCH. Consistent with pre-#402 CDD.md source; necessary for operational legibility; project bindings may override in `<project>/.cds/POLICY.md`. No follow-up filed. |
| β2 — Full STATUS state machine depth in §Cross-repo proposals | `beta-review.md §Findings` | informational | NO-PATCH. Depth is contract-pinned by the issue body D1 description; not improvisation. No follow-up filed. |
| β3 — §Location matrix legacy/scratch column preservation | `beta-review.md §Findings` | informational | NO-PATCH. Legacy paths still active in the empirical anchor; preservation makes the canonical statement honest. No follow-up filed. |

**Total findings:** 6 (3 α, 3 β); **all informational (NO-PATCH)**; **no `cds-*-gap` markers triggered**; **no `cdd-*-gap` markers triggered**; `protocol_gap_count: 0`.

## §9.1 trigger assessment

Per `cnos.cdd/skills/cdd/CDD.md` §9.1 (now §Field 5 ε iteration cadence in CDS) cycle iteration triggers:

| Trigger | Fired? | Detail |
|---|---|---|
| Review rounds > 2 | No | R1 APPROVED |
| Mechanical-finding overload (mechanical findings > 20% of total) | No | All 6 findings informational; 0 mechanical findings |
| Avoidable tooling / environment failure | No | No tooling failures during the cycle |
| Loaded skill failed to prevent a finding | No | No skill gaps surfaced |
| AC oracle ambiguity recurrence | No | All 10 oracles unambiguous; mechanical verification clean |
| CI red post-merge | N/A | No CI surface attaches to this docs-only cycle |

**No triggers fired.** The cycle-iteration artifact (`cdd-iteration.md`) is filed as a **courtesy stub** per cnos#401 cadence rule (`protocol_gap_count: 0` → optional artifact, but write a stub for traceability).

## Configuration-floor declaration

This cycle ran **γ+α+β collapsed on δ** (β-α-collapse-on-δ for skill/docs-class cycles per CDS §Field 6 Actor collapse rule). Per `cnos.cdd/skills/cdd/release/SKILL.md §3.8`:

- **α-axis: A-** (configuration-floor cap)
- **β-axis: A-** (configuration-floor cap)
- **γ-axis: A** (γ-axis not collapsed — γ scaffolded with separate identity; γ-axis full A)

The collapse is acknowledged in `gamma-scaffold.md §"Dispatch shape"`, `beta-review.md §Reviewer-ask-list`, `beta-closeout.md §"Configuration-floor declaration"`, and this section. The collapse is the structural admission that on canonical-content moves the α-β independence buys less than on novel-executable cycles, so the configuration-floor adapts.

## Coherence delta

The cycle's coherence delta is structural: every "pending cds extraction" forwarding for §Coordination surfaces and §Artifact contract resolves into a CDS-owned canonical home. The extraction-map rows 3+4 status updates make the migration auditable. Sub 6 (CDD.md marker cleanup) can now sweep against this commitment.

After Sub 4:
- Subs 1 (cnos#406), 2 (cnos#407), 3 (cnos#408), 4 (cnos#409) — landed (this cycle being the 4th).
- Sub 5 (review CLP + gate + closure + assessment + retro-packaging + non-goals + mechanical + large-file) — queued behind this.
- Sub 6 (CDD.md marker sweep) — queued after Sub 5.
- Sub 7 (empirical anchor doc) — queued.

## Deferred outputs

- **Next MCA:** Sub 5 of cnos#403 (the operator dispatches when ready). Sub 5 owns §Review CLP, §Gate, §Closure, §Assessment, §Retro-packaging, §Non-goals, §Mechanical, §Large-file (per extraction-map §5–§12). Same B-lite shape applies.
- **MCI freeze state:** not changed by this cycle. The cnos#403 wave continues to be the active MCI; this cycle is one of its subs.
- **Target branch for next MCA:** `cycle/{Sub-5-issue-number}` from origin/main after this cycle merges.

## Hub memory writes

This cycle's hub-memory delta is the addition of two top-level canonical sections to CDS.md, recorded in:
- `src/packages/cnos.cds/skills/cds/CDS.md` (canonical home; section manifest updated)
- `src/packages/cnos.cds/docs/extraction-map.md` rows 3+4 (migration ledger)
- `.cdd/iterations/INDEX.md` (one row added below — courtesy stub for `protocol_gap_count: 0`)

## Closure declaration

This cycle is **closeable** per CDD.md §Closure (canonically: CDS §Closure pending Sub 5):

- AC1–AC10 PASS ✓
- CDS.md has §Coordination surfaces and §Artifact contract as canonical homes ✓
- cnos.cdd untouched (AC7) ✓
- cnos.cdr untouched (AC8) ✓
- `.cdd/` → `.cds/` planned re-rooting documented but not performed (AC6) ✓
- extraction-map.md Status column reflects the migration for rows 3+4 (AC9) ✓
- `cdd-iteration.md` courtesy stub filed (per cnos#401 cadence rule)
- Close-out artifact set (`gamma-scaffold.md`, `self-coherence.md`, `beta-review.md`, `alpha-closeout.md`, `beta-closeout.md`, `gamma-closeout.md`, `cdd-iteration.md`) on `cycle/409` ✓
- INDEX.md row added (below)

γ declares closure. Operator merges `cycle/409` when ready.
