# Self-coherence — 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`)
**Author:** α (collapsed γ+α+β on δ)
**Date:** 2026-05-23

## Summary

All 11 acceptance criteria from [cnos#421](https://github.com/usurobor/cnos/issues/421) PASS mechanically. The survey doc at `docs/gamma/design/ccnf-o-track-a1-survey.md` carries five pinned decisions (name = CCNF-O; 20-surface inventory matrix; 6 higher-level forms classified as universal; Track B1 dispatches in parallel with Track A2; package = `cnos.ccnf-o`), six refined sub-issue paragraphs (Tracks A2–A6 + B1), and ten deferred questions flagged to named downstream Tracks.

## AC verification

### AC1 — Survey doc exists; ≥ 300 lines

`test -f docs/gamma/design/ccnf-o-track-a1-survey.md` → exit 0.
`wc -l docs/gamma/design/ccnf-o-track-a1-survey.md` → **382**.

**PASS** — 382 ≥ 300.

### AC2 — §1 names ONE of CCNF-O / CCNF-X with 1-paragraph rationale

`grep -c "^## 1\. Name pick" docs/gamma/design/ccnf-o-track-a1-survey.md` → **1**.

§1's "Decision" subsection pins **CCNF-O** with a multi-paragraph rationale (naming-by-consumer; reservation of `-X` for substrate-specific overlays; autonomy-level mapping at L5/L6). Single name pinned; no aliases emitted. **PASS.**

### AC3 — §2 contains a table with ≥ 15 rows × 5 columns

§2's surface inventory matrix has **20 rows** (rows 1–20) × 5 columns + a leading `#` column. The 5 required columns are: Surface / Current home / Universal CCNF-O? / Realization-specific? / Rationale. Each row's 5 columns are populated; no row carries empty cells. **PASS** — 20 ≥ 15.

### AC4 — §3 covers all 6 higher-level forms with classification + rationale

§3 has six numbered sub-sections:

- §3.1 SimpleCycle — Universal — rationale present
- §3.2 SubstantialCycle — Universal (shape) + realization-derived (artifact set) — rationale present
- §3.3 Wave — Universal — rationale present
- §3.4 Roadmap — Universal — rationale present
- §3.5 CoherenceMeasuredCell — Universal — rationale present
- §3.6 AutonomousLoop — Universal — rationale present

§3.7 carries a summary table of all six. **PASS** — all 6 forms covered with classification + rationale.

### AC5 — §4 explicitly states whether Track B1 can dispatch in parallel + lists touchpoints + dependencies

§4 opens with a headline "Track B1 can dispatch in parallel with Track A2" and a "Why parallel design is safe" subsection. §4 then enumerates three "Design touchpoints (Track A ↔ Track B)" — (1) CoherenceMeasuredCell form, (2) receipt-stream / iteration aggregator, (3) IssueProposal pipeline (B2 → B4) — and four "Track B1 dependencies on Track A" rows (name pinned; package location pinned; TSCReport classification confirmed; CoherenceMeasuredCell classification confirmed). Explicit out-of-scope-for-v0.1 section closes. **PASS.**

### AC6 — §5 pins ONE of three options with package-name candidate + rationale

§5 enumerates three options (a/b/c) with verdicts; (b) pinned. Package name pinned: **`cnos.ccnf-o`**. Rationale is multi-paragraph (naming convention; reason-to-change; discoverability). §5 also sketches the eventual package shape and explicitly defers the coherence controller's location to Track B4. **PASS.**

### AC7 — §6 has paragraph-level descriptions for Track A2, A3, A4, A5, A6, B1 (≥ 6 paragraphs)

§6 carries six sub-sections (one paragraph each):

- ### Track A2 — Type dispatch-prompt + implementation-contract schemas
- ### Track A3 — Type issue-pack + cell schemas
- ### Track A4 — Type findings state machine + closeout-receipt chain
- ### Track A5 — Type wave manifest + master/sub graph + composition operators
- ### Track A6 — Wire CCNF-O validation into `cn cdd verify`; add `cn cdd validate-plan`
- ### Track B1 — Define TSC report attachment for accepted CCNF receipts

Each names the dispatch-brief pin shape + gate. **PASS** — 6 ≥ 6.

### AC8 — No implementation diff

```
git diff origin/main..HEAD -- src/packages/   → 0 lines
git diff origin/main..HEAD -- schemas/         → 0 lines
git diff origin/main..HEAD -- src/go/          → 0 lines
```

**PASS** — three independent diffs each return 0 lines.

### AC9 — No CCNF kernel changes

```
git diff origin/main..HEAD -- \
  src/packages/cnos.cdd/skills/cdd/CDD.md \
  src/packages/cnos.cdd/skills/cdd/COHERENCE-CELL.md \
  src/packages/cnos.cdd/skills/cdd/COHERENCE-CELL-NORMAL-FORM.md
→ 0 lines
```

**PASS.**

### AC10 — `docs/gamma/design/README.md` has a row for the survey

`grep -c "ccnf-o-track-a1-survey" docs/gamma/design/README.md` → **1**. The README's Document Map carries one row for the survey doc. (`docs/gamma/essays/README.md` is NOT updated — the survey lands in `design/`, not `essays/`; the dispatch brief explicitly permits this judgment.) **PASS.**

### AC11 — No CCNF-O / no schemas / no handoff edits

```
test ! -d schemas/ccnf-o                                  → exit 0
git diff origin/main..HEAD -- src/packages/cnos.handoff/  → 0 lines
git diff origin/main..HEAD -- src/packages/cnos.cdr/      → 0 lines
git diff origin/main..HEAD -- src/packages/cnos.cds/      → 0 lines
```

All four checks pass. **PASS.**

## Files outside cycle/421's diff (verified untouched)

- `src/packages/cnos.cdd/` — only the kernel files were grep-tested (AC9); the broader package is in the AC8 src/packages diff = 0 set.
- `src/packages/cnos.handoff/` — AC11 ✓.
- `src/packages/cnos.cds/` and `src/packages/cnos.cdr/` — AC11 ✓.
- `src/packages/cnos.core/` and `src/packages/cnos.eng/` — covered by AC8 src/packages diff.
- `schemas/` — AC8 ✓.
- `src/go/` — AC8 ✓.
- `docs/gamma/essays/README.md` — left untouched (the survey landed in `docs/gamma/design/`, not in `essays/`).
- `docs/gamma/cdd/` — historical PRAs untouched.
- `docs/alpha/`, `docs/beta/`, `docs/delta/` — untouched (no cite-changes needed).
- `.cdd/iterations/INDEX.md` — receives the cycle-close row in the β commit (see below).

## Hard rules re-verified

1. **No implementation.** No CUE schemas authored; no Go types generated; no `cn cdd verify` changes. AC8 ✓.
2. **No CCNF kernel changes.** AC9 ✓.
3. **No cnos.handoff edits.** AC11 ✓.
4. **No src/packages edits.** AC8 ✓.
5. **No schemas/ edits.** AC8 + AC11 ✓.
6. **No #405 body edits.** Verified — the survey is an external decision artifact; #405's body is unchanged.

## Verdict

**APPROVE.** All ACs PASS. Cycle is ready for the β commit (review + close-outs) and merge.
