# γ close-out — cycle/406 (Sub 1 of cnos#403)

**Issue:** [cnos#406](https://github.com/usurobor/cnos/issues/406) — Bootstrap cnos.cds package skeleton + extraction map.
**Mode:** design-and-build; γ+α+β collapsed on δ.
**Rounds:** R1 APPROVED.
**ACs:** 7/7 PASS.
**Parent:** [cnos#403](https://github.com/usurobor/cnos/issues/403) (cnos.cds bootstrap tracker; this is Sub 1 of 7; gates Sub 2).

## Triage table

| Source | Finding | Class | Disposition |
|---|---|---|---|
| β-review Obs-1 | `## v0.1 caveat` section in cds/SKILL.md (beyond cdr shape) | non-binding | Accepted as under-promising-and-documenting; necessary because cds Sub 1 ships loader without CDS.md (Sub 2 territory). No patch. |
| β-review Obs-2 | Additional Conflict rule (kernel/realization conflict) | non-binding (doctrine-coherence improvement) | Accepted; makes the kernel-realization hierarchy explicit consistent with Cross-protocol relationship section. No patch. |
| β-review Obs-3 | `delta/` role-overlay naming (vs cdr's legacy `operator/`) | non-binding (arguable improvement) | Accepted; consistent with cycle-394+ trend toward role-letter directory naming. No patch. |
| β-review Obs-4 | §14 open-questions in extraction-map.md | non-binding (Sub-3-through-Sub-5-enabling) | Accepted; records migration-coordination questions that save next cycle's δ from rediscovering them. No patch. |
| β-review Obs-5 | §13 coverage-verification table in extraction-map.md | non-binding (Sub-6-enabling) | Accepted; makes Sub-6 marker-sweep mechanical. No patch. Recorded as candidate for future #406-style bootstrap-cycle AC clarification. |
| β-review Obs-6 | 4 of 14 CDD.md markers folded into related tables | non-binding (editorial; explicit in §13) | Accepted; folding decisions documented in §13. No patch. |

**Total findings:** 6 non-binding observations, 0 binding, 0 `cdd-*-gap`.

`protocol_gap_count` for this cycle: **0**.

## §9.1 trigger assessment

| Trigger | Fire condition | Fired? |
|---|---|---|
| Review churn | review rounds > 2 | No (R1 APPROVED) |
| Mechanical overload | mechanical ratio > 20% AND findings ≥ 10 | No (0 binding findings) |
| Avoidable tooling / environment failure | environment blocked | No (cn build --check ran cleanly) |
| CI red on merge commit | CI fails post-merge | TBD (pre-merge; operator authority) |
| Loaded skill failed to prevent a finding | skill underspecified | No (no findings) |

No §9.1 triggers fired.

## Coherence delta

This cycle shipped:

- **`cnos.cds` package skeleton** — the third domain-realization package alongside `cnos.cdd` (kernel) and `cnos.cdr` (research realization). `cn build --check` reports `cnos.cds: valid`; the package is discoverable by cn package-discovery without any changes to cnos.core discovery code.
- **Extraction map** — the load-bearing artifact of Sub 1; 12 surface-group tables covering all 10 #403-named surfaces; §13 coverage-verification table mapping all 14 CDD.md "pending cds extraction" markers to their containing tables; §14 open-questions section recording 5 migration-coordination questions for Subs 3–5. Subs 3–5 can now dispatch against named destinations rather than re-deriving them.
- **Sub 2 unblocked** — CDS.md authoring (Sub 2 of #403) can dispatch against the extraction-map's destination commitments; the destinations name "skills/cds/CDS.md §X" sections that Sub 2 will create.
- **Sub 6 enabled** — extraction-map §13 makes the marker-sweep mechanical: Sub 6 reads each CDD.md "pending cds extraction" marker, looks up its containing table in §13, verifies the content migrated in Sub 3/4/5, removes the marker. No re-derivation needed.
- **Sub 7 unblocked** — the `docs/empirical-anchor-cdd.md` placement home is named in README's "Forthcoming surfaces" section; the cnos.cdr/docs/empirical-anchor-cph.md structural precedent is cited.
- **Sibling-package cross-reference loop closed** — cdr/SKILL.md's "CDR is not CDS-with-different-words" forward-reference now resolves to an existing peer package containing the reciprocating distinction.

The cycle does not modify cnos.cdd, cnos.cdr, schemas, harness, CI, runtime, or build surfaces. The work is package-skeleton creation + extraction-map authoring.

## Configuration-floor declaration

Per `release/SKILL.md §3.8`, this cycle's γ+α+β-collapsed-on-δ pattern caps both γ-axis and β-axis at A- (γ/δ separation absent; β-α collapse acknowledged per Rule 7). The cap is documented in the gamma scaffold ("Dispatch shape" section) and is appropriate for skill/docs-class cycles per the breadth-2026-05-12 wave manifest precedent.

## Closure declaration

**Cycle #406 closed (α/β/γ-level; merge pending operator action).** All seven ACs verified PASS. β-review APPROVED R1. Six non-binding observations recorded; zero binding findings. No `cdd-*-gap` findings; `protocol_gap_count = 0`.

Per the cycle/401 cadence rule, `cdd-iteration.md` is **not required** when `protocol_gap_count == 0`. A courtesy empty-findings stub is filed under `.cdd/unreleased/406/cdd-iteration.md` for traceability and per the dispatch's "courtesy empty-findings stub" obligation; an INDEX.md row is appended per the cycle/401 courtesy convention.

**Receipt obligation per CDD §5.5b:** the cycle's parent-facing artifact is the merged branch + closed issue. cycle/406 ships to origin (push pending); operator merges with `Closes #406` keyword in the merge commit to auto-close the issue. The receipt set (close-outs + cdd-iteration + INDEX row) is filed under `.cdd/unreleased/406/`.

**Next (operator action):**

1. Operator pulls `cycle/406` from origin, reviews the changes (5 new files under `src/packages/cnos.cds/` + 8 cycle-artifact files under `.cdd/unreleased/406/` + 1 INDEX row).
2. Operator merges with `git merge cycle/406 --no-ff` and commit message including `Closes #406` to auto-close the issue.
3. cycle/406 branch is deleteable post-merge (no further activity expected on this branch).
4. With Sub 1 closed, Sub 2 (CDS.md authoring) becomes dispatchable; the extraction map's destinations are the contract Sub 2 fulfills.
