# γ closeout — Cycle 421

**Cycle:** [cnos#421](https://github.com/usurobor/cnos/issues/421) — Track A1 of [cnos#405](https://github.com/usurobor/cnos/issues/405)
**Branch:** `cycle/421` (from `origin/main` @ `9fc04a99`)
**Closer:** γ (collapsed γ+α+β on δ)
**Date:** 2026-05-23

## What this cycle shipped

A single design artifact — the Track A1 survey + decision doc — and a new `docs/gamma/design/` directory home (with README) for survey + decision-class documents.

| Artifact | Path | Lines | Class |
|---|---|---|---|
| Track A1 survey | `docs/gamma/design/ccnf-o-track-a1-survey.md` | 382 | Survey + decision (v0.1) |
| Design dir README | `docs/gamma/design/README.md` | 26 | Document Map |
| γ scaffold | `.cdd/unreleased/421/gamma-scaffold.md` | 82 | Cycle scaffold |
| Self-coherence | `.cdd/unreleased/421/self-coherence.md` | — | AC pass-set |
| β review | `.cdd/unreleased/421/beta-review.md` | — | Substantive review |
| α closeout | `.cdd/unreleased/421/alpha-closeout.md` | — | α-side close |
| β closeout | `.cdd/unreleased/421/beta-closeout.md` | — | β-side close |
| γ closeout | `.cdd/unreleased/421/gamma-closeout.md` | — | this file |
| cdd-iteration (courtesy stub) | `.cdd/unreleased/421/cdd-iteration.md` | — | `protocol_gap_count = 0` |

## The five pinned decisions

1. **Name:** CCNF-O — Coherence Cell Normal Form, Orchestration overlay. Operator's preference confirmed; consumer-naming convention; `-X` slot reserved for per-substrate stratification.
2. **Surface inventory:** 20 surfaces classified. 12 universal CCNF-O; 7 handoff-resident (CCNF-O may type, handoff owns); 1 split (Finding + closeout chain — universal in shape, realization-specific in vocabulary).
3. **Higher-level forms:** all 6 (`SimpleCycle` / `SubstantialCycle` / `Wave` / `Roadmap` / `CoherenceMeasuredCell` / `AutonomousLoop`) universal in shape. Only `SubstantialCycle`'s per-realization artifact-set fill is realization-specific.
4. **TSC integration v0.1 scope:** Track B1 dispatches in parallel with Track A2; 3 design touchpoints (CoherenceMeasuredCell, receipt-stream/aggregator, IssueProposal pipeline); Track B1 depends on Track A1 (this cycle) only — not on A2.
5. **Package location:** new `cnos.ccnf-o` package, peer to `cnos.cdd` / `cnos.cds` / `cnos.cdr` / `cnos.handoff`. Option (a) (sub-dir of cnos.cdd) and (c) (fold into cnos.handoff) rejected with reason.

## What becomes dispatchable

- **Track A2** — type dispatch-prompt + implementation-contract schemas. Gate satisfied by close-of-#421.
- **Track B1** — design TSC report attachment. Gate satisfied by close-of-#421. May dispatch in parallel with Track A2.

The remaining Tracks (A3 / A4 / A5 / A6 / B2 / B3 / B4 / B5 / B6) chain off Track A2 + B1 per the per-Track gates in §6 of the survey.

## AC verification

All 11 ACs PASS mechanically. See [`self-coherence.md`](self-coherence.md) for the full pass-set; [`beta-review.md`](beta-review.md) for substantive review.

## Hard rules honored

1. ✓ No implementation (no CUE; no Go; no `cn cdd verify`).
2. ✓ No CCNF kernel changes (CDD.md / COHERENCE-CELL.md / COHERENCE-CELL-NORMAL-FORM.md untouched).
3. ✓ No `cnos.handoff` edits.
4. ✓ No `src/packages/` edits at all.
5. ✓ No `schemas/` edits; `schemas/ccnf-o/` does not exist.
6. ✓ No #405 body edits.

## Mid-flight observations

- **Branch creation went clean.** No tooling issues; `cycle/421` created from `origin/main @ 9fc04a99` on first attempt. The prior-cycle stall (cycle/420 β→γ transition) did not recur this cycle. γ scaffold filed immediately; α work batched into one commit; β review batched with closeouts into a third commit. Operator's "finalize early" note from the dispatch brief honored — closeouts authored before β commit + push.
- **Design directory created.** `docs/gamma/design/` did not exist pre-cycle. Created with a README per the dispatch brief's D2 requirement (judgment call: the survey is decision-class, not essay-class; `docs/gamma/design/` is the categorically correct home).
- **No `gamma-clarification.md` triggered.** All implementation-contract axes held throughout the cycle; no mid-flight re-pin.

## Operator action on close

Merge `cycle/421` to `main` with `--no-ff`:

```
Merge cycle/421: Track A1 of #405 — CCNF-O survey + name-pick + sub-issue queue. Closes #421.
```

#405 stays open. Tracks A2 + B1 dispatchable; agent does NOT self-merge — operator merges.

## Receipt summary
