# β-review — Cycle 416

**Cycle:** [cnos#416](https://github.com/usurobor/cnos/issues/416) — Sub 2 of [cnos#404](https://github.com/usurobor/cnos/issues/404).
**Branch:** `cycle/416` from `origin/main @ 92a7442d`.
**Mode:** γ+α+β collapsed on δ. β is the adversary witness to α's claims, run independently against the AC suite.

## Adversary stance

α's `self-coherence.md` claims AC1–AC10 PASS. β re-runs every check against the working tree at the α-commit (HEAD before β-commit) without relying on α's reported numbers.

## AC re-verification — β as adversary

### AC1: file existence — PASS

```
$ ls -la src/packages/cnos.handoff/skills/handoff/HANDOFF.md \
        src/packages/cnos.handoff/skills/handoff/cross-repo/SKILL.md \
        src/packages/cnos.cdd/skills/cdd/cross-repo/SKILL.md
HANDOFF.md                3161 bytes
cross-repo/SKILL.md      41559 bytes
cdd/cross-repo/SKILL.md   1210 bytes
```

3 files exist with non-zero size. ✓

### AC2: doctrine preservation in new SKILL.md — PASS

- Line count: 643 (≥ 600). The original at `origin/main` was 643 (`wc -l` confirms; AC2 expected ≥ 600 to cover the original 644 ± frontmatter edits). Note: the original file's `wc -l` returned 643 (not 644 — the issue body's "644 lines" figure rounds up by 1, likely counting EOF newline). The transport preserved every doctrine paragraph; the only deletions are 1 `requires:` line and the change of `calls:` from 3 simple lines to 3 prefixed lines.
- Distinct keywords present (`rg -o "..."` returned 6 unique terms): `LINEAGE`, `STATUS`, `bundle archival`, `cross-repo state machine`, `feedback patch`, `hat-collapse`. ≥ 6 ✓

### AC3: stub is short — PASS

- 28 lines (≤ 50). Distinct pointer-keywords: 4 (`canonical`, `cnos.handoff`, `handoff/cross-repo`, `moved`). ≥ 3 ✓

### AC4: STATUS-canonical-home flipped — PASS

- Exact text in new SKILL.md §2.3 preamble: "**The STATUS vocabulary is canonical in this skill (§2.3); CDS / CDR / CDD bind or consume it, but do not own it.**"
- The previous text ("**canonical in `cnos.cds/skills/cds/CDS.md` §'Coordination surfaces' → §'Cross-repo proposals'**") is no longer present. β confirms by `rg`:
  ```
  $ rg "canonical in .cnos.cds" src/packages/cnos.handoff/
  (no matches)
  ```
  ✓

### AC5: HANDOFF.md is minimal — PASS

- 62 lines, in the 50–150 window. ✓

### AC6: no old-path-as-canonical citations remain — PASS

- `rg "cnos\.cdd/skills/cdd/cross-repo/SKILL\.md.*canonical|cdd/cross-repo.*canonical" src/packages/cnos.cdd/skills/cdd/ src/packages/cnos.cds/skills/cds/ src/packages/cnos.cdr/skills/cdr/` returns 0 hits. ✓

### AC7: ≥ 3 consumer cites of new canonical path — PASS

- Total: 14 cites across cdd + cds (5 cdd files including the stub; 6 cites in CDS.md; 1 self-cite in handoff loader prose left untouched as v0.1-caveat scope is Sub 3+). ≥ 3 ✓

### AC8: no behavioral redesign — PASS

β diff-checked §1–§2 (the doctrine body) between `origin/main`'s `cnos.cdd/skills/cdd/cross-repo/SKILL.md` and the new `cnos.handoff/skills/handoff/cross-repo/SKILL.md`:

```
$ diff <(sed -n '/^## 1\. Define/,/^## 3\. Rules/p' /tmp/old_skill.md) \
       <(sed -n '/^## 1\. Define/,/^## 3\. Rules/p' src/packages/cnos.handoff/skills/handoff/cross-repo/SKILL.md)
```

Returns 20 lines of diff. The diff shows **only 4 substantive change-sites** in the entire 400-ish-line doctrine body:

1. **§2.3 preamble** — STATUS-canonical-home declaration flipped (AC4-required edit).
2. **§2.3.1 header** — removed parenthetical "(per CDS §...)". The vocabulary is now declared canonical *here*; the parenthetical attribution to CDS would contradict that.
3. **§2.3.3 prose** — first sentence cited CDS.md as the source of the "only event required" rule; now self-references §2.3.1 above. Internal-consistency edit.
4. **§2.5 Case (c) table row + §2.9 hat-collapse Authority-basis** — relative cite `post-release/SKILL.md` / `epsilon/SKILL.md` rewritten to absolute `cnos.cdd/skills/cdd/{role}/SKILL.md` (cross-package path required since the file now lives in cnos.handoff).

All other §1–§2 lines are character-for-character identical to the original. The 8 STATUS events, the transition graph, the master/sub `landed` rule, the 4 directional case definitions with sub-shapes (a.1, a.2, b.1, c, d.1, d.2, d.3), the bundle file sets per case, the LINEAGE schemas per case, the feedback-patch header form, the bundle archival rule (§2.8 asymmetric), the hat-collapse two-places rule (§2.9), and the 6 known protocol edge cases (§2.10) with their empirical anchors (cn-sigma/agent-activate-skill, cph/bootstrap-cdr, cn-sigma post-filing refinement, asymmetric source posture, cph/coherence-drift-sweep-followup, cph/issue-32-tightening, cn-rho/bootstrap) are byte-equivalent to origin/main. ≥ 5 verbatim structural elements ✓ (in fact 11+).

The §3 Rules / §4 Verify / §5 Cross-references / §6 Kata blocks have similarly narrow diffs — §5 was expanded to add the new `cnos.cds/skills/cds/CDS.md §"Coordination surfaces"` consumer cite and to absolute-path all cdd cites; §3.10 reworded "Other CDD skills" → "Consumer protocol skills"; §6 kata gamma cite became absolute. Doctrine unchanged.

### AC9: no out-of-scope changes — PASS

- `test ! -d schemas/handoff` ✓
- `test ! -d schemas/ccnf-o` ✓
- `git diff origin/main..HEAD --stat -- src/packages/cnos.cdd/commands/cdd-verify/` empty (0 lines) ✓
- `git diff origin/main..HEAD --stat -- src/go/` empty ✓
- `git diff origin/main..HEAD --stat -- scripts/release.sh` empty ✓

### AC10: extraction-map updated — PASS

- `rg -c "v0.1 migrated" src/packages/cnos.handoff/docs/extraction-map.md` returns 8 (1 preamble + 7 row notes). ✓
- Other sections (§2 dispatch through §11 open questions) untouched per β's `git diff` inspection of the extraction-map.

## Adversary scope-check

β probed for things α might have missed:

- **Did α touch any α-forbidden surface?** No — no `src/go/` changes, no `scripts/release.sh` changes, no `src/packages/cnos.cdd/commands/cdd-verify/` changes. `git diff --stat origin/main..HEAD` confirms changes are confined to: `.cdd/unreleased/416/*`, `src/packages/cnos.cdd/skills/cdd/{cross-repo,gamma,post-release,epsilon}/SKILL.md`, `src/packages/cnos.cds/skills/cds/CDS.md`, `src/packages/cnos.handoff/{docs/extraction-map.md,skills/handoff/{HANDOFF.md,cross-repo/SKILL.md,.gitkeep[deleted]}}`. All in-scope per the dispatch contract.
- **Did α invent vocabulary?** No — every STATUS event name, case identifier (a.1, a.2, b.1, c, d.1, d.2, d.3), bundle file name (LINEAGE.md, STATUS, FEEDBACK.patch, ISSUE.md, cdd-iteration.md), and rule numbering preserved verbatim from origin/main.
- **Did α author any new schema?** No — no `schemas/handoff/` directory created; HANDOFF.md is prose only.
- **Did α delete the old file?** No — replaced with compatibility stub, as the operator ruling explicitly required.
- **Are the consumer cite repairs correct?** β spot-checked the 4 cdd files + 1 cds file:
  - `cnos.cdd/skills/cdd/gamma/SKILL.md` — both cites now point at `../../../../cnos.handoff/skills/handoff/cross-repo/SKILL.md` (relative from `cnos.cdd/skills/cdd/gamma/` up to `src/packages/` and back into cnos.handoff). Path math verified: 4 `..` segments yields `src/packages/`, then `cnos.handoff/skills/handoff/cross-repo/SKILL.md`. ✓
  - `cnos.cdd/skills/cdd/post-release/SKILL.md` — same relative path; identical depth; ✓
  - `cnos.cdd/skills/cdd/epsilon/SKILL.md` — same relative path; identical depth; ✓
  - `cnos.cds/skills/cds/CDS.md` — uses `../../../cnos.handoff/skills/handoff/cross-repo/SKILL.md` (3 `..` from `cnos.cds/skills/cds/` up to `src/packages/`); ✓
  - cnos.cdd stub at `cross-repo/SKILL.md` uses `../../../../cnos.handoff/...` (4 `..` from `cnos.cdd/skills/cdd/cross-repo/`); ✓

## Findings

**β finds no defects in α's work.** The transport is mechanically clean; the verbatim doctrine is preserved with surgical precision; the canonical-authority cites are all re-pointed; the compatibility stub honors the operator ruling; the extraction-map row updates are unambiguous.

The intentional in-scope edits are exactly the 5 categories α listed:
1. Frontmatter triage (`parent:`, `requires:`, `calls:`)
2. Authority paragraph rewritten to declare cnos.handoff as canonical
3. §2.3 STATUS-canonical-home flip (the substantive doctrine edit)
4. §2.3.1 / §2.3.3 self-referential cite updates (internal-consistency)
5. Cross-package cite expansion (relative → absolute) at §2.5 / §2.9 / §3.10 / §5 / §6

Every other line is byte-identical to origin/main's cnos.cdd source.

## Verdict

**AC1–AC10 all PASS** under β's independent re-run.

Sub 2 of cnos#404 is closeable. β attests the cycle's deliverables D1–D5 meet the dispatch contract without behavioral redesign, without out-of-scope changes, and without protocol drift.

Recommend: γ files the three closeouts (α / β / γ) + the cdd-iteration courtesy stub + INDEX.md row, then pushes `cycle/416`. The merge to main is operator's call (`Closes #416`).
