# β review R1 — cycle/415

**Issue:** [cnos#415](https://github.com/usurobor/cnos/issues/415) — Sub 1 of [#404](https://github.com/usurobor/cnos/issues/404): Bootstrap `cnos.handoff` package skeleton + extraction map
**Branch:** `cycle/415` (HEAD `cb40e282`)
**Round:** R1
**Reviewer mode:** β-α-collapse-on-δ; independent oracle on the mechanical ACs; configuration-floor respected (this is docs-class matter per cnos.cds Field 6 collapse rule).

## CLP — Cycle Loss Predicate

**TERMS.** Sub 1 of cnos#404 succeeds iff (a) the cnos.handoff package exists at the canonical path and is discoverable by `cn build --check`; (b) the README, SKILL.md, and extraction-map.md ship in the shapes the 9 ACs require; (c) no cnos.cdd / cnos.cdr / cnos.cds content is modified; (d) no CCNF-O schemas, cn-cdd-verify changes, or runtime/harness changes are made; (e) the extraction map covers the 6 required surface families with destinations under cnos.handoff/ and migration-sub assignments.

**POINTER.** The 9 ACs in cnos#415's "Acceptance criteria" section are the authoritative oracle.

**EXIT.** APPROVE iff all 9 ACs pass mechanical or read-check verification AND no judgment-axis findings block close. REQUEST CHANGES iff any AC fails or any judgment-axis finding has severity ≥ C.

## Per-AC verdict

| AC | Verdict | Evidence |
|---|---|---|
| AC1 — files at canonical paths | PASS | All 4 required files present (`cn.package.json`, `README.md`, `skills/handoff/SKILL.md`, `docs/extraction-map.md`); README is 77 lines (≥ 50). |
| AC2 — `cn` discovery | PASS | `cn build --check` (built from `src/go/cmd/cn` at HEAD) reports `✓ cnos.handoff: valid`. No `cnos.core` discovery code modified. |
| AC3 — README cross-protocol claims | PASS | Read-check confirms: wire-format ownership stated; cdd/cds/cdr named as 3 current consumers; CCNF-O boundary stated with "different reasons to change" framing; cnos#404 cited as parent (6 cites); cdd/cross-repo/SKILL.md named as primary absorption target. |
| AC4 — SKILL.md mirrors cds/cdr | PASS | Read-check: frontmatter has all required fields (`name`, `description`, `artifact_class`, `governing_question`, `triggers`, `calls`) plus the same optional fields cnos.cds uses (`kata_surface`, `visibility`, `scope`, `inputs`, `outputs`, `requires`). `calls:` names HANDOFF.md + 5 sub-skill files as advisory targets. Section shape mirrors cnos.cds (load order; rule; sub-skills; cross-protocol; conflict rule; v0.1 caveat). |
| AC5 — extraction map ≥ 6 surfaces | PASS | `grep -c "^## " docs/extraction-map.md` = 12. 6 required families covered (§1–§6); 2 discovered surfaces (§7 polling; §8 spec-staleness); close-out row (§9). 43 sub-assignment rows total across the map. Every destination path resolves under `cnos.handoff/`. |
| AC6 — cnos.cdd / cnos.cdr / cnos.cds untouched | PASS | `git diff origin/main..HEAD -- src/packages/<pkg>/ \| wc -l` = 0 for each of the three packages. `cnos.handoff/skills/handoff/HANDOFF.md` does not exist (`.gitkeep` is the placeholder). |
| AC7 — no CCNF-O typing | PASS | `test -d schemas/ccnf-o/` returns nonzero — directory absent. |
| AC8 — no cn-cdd-verify changes | PASS | `git diff origin/main..HEAD -- src/packages/cnos.cdd/commands/cdd-verify/ \| wc -l` = 0. |
| AC9 — no runtime/harness changes | PASS | `git diff origin/main..HEAD -- src/go/ \| wc -l` = 0. |

## Judgment-axis findings

### J1: HANDOFF.md present-or-absent (gamma-scaffold.md §J1)

**Finding:** α's decision to omit `HANDOFF.md` and use `.gitkeep` instead is structurally correct.

**Reasoning (β-independent):** The cnos.cds Sub 1 precedent (cnos#406) shipped without `CDS.md`; the loader-skill's v0.1 caveat section already names the file as forthcoming and points readers at the extraction map. A 1-paragraph stub would add no information and would force Sub 2 or Sub 3 to overwrite rather than create — a churn cost with no benefit. `.gitkeep` is the cleaner option.

**Severity:** info (judgment confirmed; no change needed).

### J2: Extraction-map source paths after post-#411 reality (gamma-scaffold.md §J2)

**Finding:** α correctly noted that several extraction-target surfaces named in #415's D2 are no longer in `cnos.cdd` — they migrated to `cnos.cds/skills/cds/CDS.md` during the cnos#403 wave (Subs 2–5 of that wave). α recorded each row's source path at its current canonical home (some in cnos.cdd, some in cnos.cds), and flagged the rows where the canonical home is now cnos.cds with `migration-semantics-undecided` in the note column.

**β verification:** I read `cnos.cds/skills/cds/CDS.md §"Coordination surfaces"` and `§"Artifact contract"` — those sections do indeed carry the post-#411 canonical content for mid-flight clarification (§4 of the extraction map) and artifact channel rules (§5 of the extraction map). α's flagging is accurate and the recommendation per row (move / mirror / cite-only) is well-reasoned. The dispatching δ for Sub 4 makes the final call per row; the map gives them the live information they need rather than a stale citation.

**Severity:** info (correct judgment; the extraction map is more credible because it records post-#411 reality rather than pretending the surfaces are still in cnos.cdd).

### J3: operator/SKILL.md §3a deprecation handling (gamma-scaffold.md §J3)

**Finding:** α correctly noted that `cnos.cdd/skills/cdd/operator/SKILL.md §3a` is now a redirect-only pointer; canonical implementation-contract enrichment doctrine lives at `cnos.cdd/skills/cdd/delta/SKILL.md §2`. Extraction-map row §2 uses `delta/SKILL.md §2` as the source pin with a parenthetical note about the §3a redirect.

**Severity:** info (correct judgment).

### J4: Additional discovered surfaces (gamma-scaffold.md §J4)

**Finding:** α discovered three additional handoff-class surfaces during authoring (polling primitives in `harness/SKILL.md §5.4`; spec-staleness propagation in `gamma/SKILL.md §2.5`; bundle file sets per case — folded into the cross-repo wholesale move). The first two are recorded as additional `##`-headed sections (§7, §8) with Sub assignments; the third is correctly folded into §1 (Sub 2's wholesale move) and not duplicated.

**β verification:** The polling-primitives discovery (§7) is the most interesting — α correctly recognized that the doctrine has split (post-#411 canonical in cnos.cds; operational realization in cnos.cdd/harness) and that the migration is contested. The recommendation to defer (leave canonical in cnos.cds + operational in cnos.cdd/harness; do not duplicate in cnos.handoff for v0.1) aligns with design-skill §3.5 "interfaces belong to consumers" — the consumer count is still one (CDS); wait for substitution pressure.

**Severity:** info (correct discoveries; well-reasoned dispositions).

### Map quality

The extraction map is the load-bearing artifact of this sub. β assesses it on three axes:

1. **Coverage.** All 6 required surface families covered; 2 discovered surfaces recorded; close-out row present. PASS.
2. **Destination specificity.** Every row commits a specific path under `cnos.handoff/` (e.g., `skills/handoff/cross-repo/SKILL.md §2.3` rather than "somewhere in cross-repo"). Where the migration mechanism is contested, the row's note column names the options (move / mirror / cite-only) and recommends one, rather than punting. PASS.
3. **Sub-dispatchability.** Reading any one row's source + destination + sub field gives the dispatching δ for that sub enough information to draft the sub's α prompt. The Open Questions section (§11) names the operational decisions each sub makes; none are blockers for Sub 1. PASS.

The map is dispatchable. Subs 2–6 can execute against it without re-deriving destinations.

## Findings

None. R1 is APPROVED.

## Verdict

**APPROVE R1.** All 9 ACs PASS; no judgment-axis findings of severity ≥ C; the package is loadable, the extraction map is credible, and the dispatching δ for Subs 2–6 has unambiguous commitments to dispatch against.

**Cycle close path:** γ files alpha-closeout / beta-closeout / gamma-closeout; γ writes cdd-iteration courtesy stub (`protocol_gap_count: 0`); γ appends INDEX.md row; γ pushes `cycle/415` to origin; operator-as-human merges with `Closes #415`.

## Configuration-floor declaration

β-α-collapse-on-δ pattern. Per `cnos.cds/skills/cds/CDS.md §"Field 6: Actor collapse rule"`:

- This cycle's matter is **docs-only + package skeleton + extraction map** (declared in #415 mode line and the dispatch metadata).
- β-α-collapse is permitted for docs-class / skill-class cycles where the matter is documentation, structure, or skeleton.
- All ACs are mechanical (file presence; line count; `cn build --check` exit; `git diff` line count) or read-checks (frontmatter field presence; section presence; cross-reference cites by name). No judgment-bearing axis required α≠β independent oracles.
- The cnos#414 cycle (essay authoring) is the immediate structural precedent for β-α-collapse-on-δ on docs-class matter.

No configuration-floor violation. β's grade under collapse is the same as β's grade would be under separation, because the oracle is mechanical.
