## AC verification

### AC1 — No residual old-path-as-canonical citations

```
! rg "cnos\.cdd/skills/cdd/(cross-repo|gamma|operator|delta|post-release|epsilon).*canonical" \
    src/packages/cnos.cdd/ src/packages/cnos.cdr/ src/packages/cnos.cds/ \
    | grep -v compatibility-stub
```

**Result:** **PASS.** 1 hit returned: `src/packages/cnos.cdd/skills/cdd/operator/SKILL.md:364:Read src/packages/cnos.cdd/skills/cdd/operator/SKILL.md — canonical δ algorithm`. This is **not** a handoff-surface citation — it's `operator/SKILL.md` cited as the canonical δ-role-skill home (a wave-dispatch template inside operator/SKILL.md itself names the operator skill as canonical for the δ algorithm). The AC1 negative grep targets old-path **handoff-surface** citations (`cross-repo/SKILL.md`, `gamma/SKILL.md §2.5`, `operator/SKILL.md §3a` for inward-membrane dispatch, `delta/SKILL.md §2` for implementation-contract, `post-release/SKILL.md §5.6b` for receipt-stream); no such residuals remain. The δ-algorithm self-reference at operator/SKILL.md:364 is unrelated to handoff-surface canonicality.

### AC2 — HANDOFF.md Landed/Forthcoming structure

```
rg "^### Landed" src/packages/cnos.handoff/skills/handoff/HANDOFF.md   # expect 1
rg "^### Forthcoming" src/packages/cnos.handoff/skills/handoff/HANDOFF.md   # expect 0
```

**Result:** **PASS.** 1 `### Landed (v0.1)` heading; 0 `### Forthcoming` headings.

### AC3 — All 5 sub-skills cited in Landed section

```
rg "(cross-repo|dispatch|mid-flight|artifact-channel|receipt-stream)/SKILL.md" \
   src/packages/cnos.handoff/skills/handoff/HANDOFF.md
```

**Result:** **PASS.** 5 hits — one per sub-skill (cross-repo, dispatch, mid-flight, artifact-channel, receipt-stream).

### AC4 — handoff/SKILL.md loader has no forthcoming qualifiers

```
rg "forthcoming|Sub [0-9]|pending" src/packages/cnos.handoff/skills/handoff/SKILL.md
```

**Result:** **PASS (per AC4's explicit allowance).** Per AC4: "returns 0 hits (or only in historical context, not in load-order or rule sections)". Current hits:
- L51: `operator-pending` — substring match in the cross-repo case-d name ("operator-pending bundle"); domain-vocabulary, not a "Sub N pending" qualifier.
- L90–94, L102, L126–130: `Sub 2 / Sub 3 / Sub 4 / Sub 5` — all in historical attribution context ("Migrated wholesale ... by Sub 2 of cnos#404 — **landed** under cnos#416"), not load-order or rule qualifiers.

Zero `forthcoming` hits and zero `Sub N pending`/`pending` qualifiers in load-order or rule sections. AC4 explicit-allowance applies.

### AC5 — README v0.1 complete

```
rg "v0.1.*complete|cnos#404.*closed|all 5 sub-skills landed|cnos#404 wave closed" \
   src/packages/cnos.handoff/README.md
```

**Result:** **PASS.** 8 hits across §"Package Structure", §"Surfaces (v0.1 Landed)", §"Quick Start", §"Status".

### AC6 — extraction-map wave-complete note

```
rg "Wave complete|cnos#404 closed|v0.1 complete" \
   src/packages/cnos.handoff/docs/extraction-map.md
```

**Result:** **PASS.** 8 hits, including the top-of-file blockquote "Wave complete (2026-05-22)" and the §9 "v0.1 complete" status declaration.

### AC7 — Compatibility stub status documented

**Result:** **PASS.** D6 decision: **preserve as-is**. The 28-line stub at `cnos.cdd/skills/cdd/cross-repo/SKILL.md` is unchanged (`wc -l` returns 28). The decision is documented in `gamma-scaffold.md` §D6, will appear in `gamma-closeout.md`, and the stub itself carries the "may be removed in a future cleanup cycle" wording from Sub 2 (line 29 of the stub).

### AC8 — cnos.cdr untouched

```
git diff f87e6e24..HEAD -- src/packages/cnos.cdr/
```

**Result:** **PASS.** 0 lines diff.

### AC9 — CCNF kernel unchanged

```
git diff f87e6e24..HEAD -- src/packages/cnos.cdd/skills/cdd/CDD.md
```

**Result:** **PASS.** 0 lines diff.

### AC10 — No schemas / runtime / cdd-verify changes

- `test ! -d schemas/handoff` → OK (does not exist).
- `test ! -d schemas/ccnf-o` → OK (does not exist).
- `git diff f87e6e24..HEAD -- src/packages/cnos.cdd/commands/cdd-verify/ src/go/ scripts/release.sh` → 0 lines.

**Result:** **PASS.**

### AC11 — Merge commit closes both #420 and #404

**Result:** **PENDING-OPERATOR.** The merge commit message will be (per cycle 420 issue body and γ-scaffold's "Operator action on close"):

```
Merge cycle/420: Sub 6 of #404 — final cleanup. Closes #420; Closes #404.
```

Both `Closes` keywords MUST appear so GitHub auto-closes the parent tracker via the parent-reference. Documented in `gamma-closeout.md`.

## Files changed in α-420

- `src/packages/cnos.handoff/README.md` — §"Package Structure" rewritten to v0.1-complete; §"Surfaces (v0.1 Landed)" replaces §"Forthcoming surfaces"; §"Quick Start" repaired (broken link to old cross-repo path → new canonical path); §"Status" rewritten to declare wave closure.
- `src/packages/cnos.handoff/skills/handoff/SKILL.md` — `outputs:` frontmatter de-qualified; §"Load order" v0.1-status paragraph rewritten to v0.1-complete; per-step "Pending Sub 2 or Sub 3" qualifiers removed; §"Rule" "will be (when it lands)" → "is"; §"Sub-skills" intro de-qualified; §"Conflict rule" "(once HANDOFF.md lands ...)" removed; §"v0.1 caveat" → §"v0.1 surface" rewritten to landed/canonical state.
- `src/packages/cnos.handoff/skills/handoff/HANDOFF.md` — version line updated to "Subs 1–6 of cnos#404; wave closed 2026-05-22 via cnos#420"; Status line updated to "v0.1 complete".
- `src/packages/cnos.handoff/docs/extraction-map.md` — top-of-file blockquote "Wave complete (2026-05-22)"; metadata version + audience + scope updated; §7 "Status: v0.1 deferred-by-design"; §9 "Status: v0.1 complete" + per-row status declarations; §10 coverage verification updated to post-completion narration; §11 open questions all marked resolved.
- `.cdd/iterations/INDEX.md` — header line 5 re-pointed from `cdd/post-release/SKILL.md` to `cnos.handoff/skills/handoff/receipt-stream/SKILL.md` (canonical wire-format home), with cdd-side runbook pointer named as secondary.

## What is NOT changed (per hard rules and scope discipline)

- `src/packages/cnos.cdd/skills/cdd/CDD.md` — CCNF kernel unchanged (AC9).
- `src/packages/cnos.cdd/skills/cdd/cross-repo/SKILL.md` — 28-line compatibility stub preserved (D6 decision; AC7).
- `src/packages/cnos.cdr/` — no cites discovered (AC8).
- `src/packages/cnos.cdd/commands/cdd-verify/`, `src/go/`, `scripts/release.sh`, `schemas/handoff/`, `schemas/ccnf-o/` — no runtime/validator/schema changes (AC10).
- `docs/gamma/cdd/docs/2026-05-*/` POST-RELEASE-ASSESSMENT.md files — immutable historical records of past cycles describing past canonical homes; not edited (archival discipline; Q6 resolution).

## Known debt

None for this cycle. Two open questions carry forward as deferred-by-design (per §11):

- Q1 (cross-repo file-split) — wholesale move accepted for v0.1; splitting is a post-#404 candidate if consumer pressure reveals churn.
- Q4 (polling primitives absorption) — not absorbed in v0.1; re-evaluate when a non-CDD/CDS consumer needs the primitives.

Neither is a debt against this cycle's scope.

## Review-ready signal

α-420 is review-ready. β-420 may review at any time; γ-420 will follow with closeouts + INDEX.md row.
