# β review (R1) — cycle/413

**Verdict:** APPROVED. All AC1–AC9 PASS. No findings; no fix-rounds required. Merge-ready (operator's call on merge timing).

β review reproduces the AC oracles independently of α's self-coherence, audits the implementation-contract conformance (per `beta/SKILL.md` Rule 7 from cnos#393), checks the doctrine-locality / case-identification rules from `cdd/cross-repo/SKILL.md §4`, and spot-checks artifacts for substantive correctness beyond mechanical-oracle satisfaction.

## R1 AC verification (independent re-run)

| AC | Oracle result | Notes |
|----|---|---|
| AC1 | PASS — 5 required files at canonical path | confirmed via `ls .cdd/iterations/cross-repo/cn-sigma/sigma-activation-2026-05-22/` |
| AC2 | PASS — case (d.2) named in first paragraph + Disposition is `drafted (operator-pending)` | confirmed via `head -5 LINEAGE.md` |
| AC3 | PASS — 6 numbered rules in PERSONA-additions.patch | confirmed via `grep -cE "^\+[0-9]+\. \*\*" PERSONA-additions.patch` = 6 |
| AC4 | PASS — 3 sub-rules in OPERATOR-additions.patch | confirmed via `grep -E "^\+### [0-9]+\." OPERATOR-additions.patch` returns Wave dispatch / B-lite extraction / Implementation contract pinned |
| AC5 | PASS — 3 attacks + TSC-observation rule in PERSONA-discipline-receipt-additions.patch | confirmed via grep counts (3 + 1) |
| AC6 | PASS — 10 `## Rule` sections in anchor doc | confirmed via `grep -c "^## Rule" docs/empirical-anchor-cnos-bootstrap-arc.md` = 10 |
| AC7 | PASS — all 3 patches apply cleanly with `git apply --recount` against synthetic cn-sigma | confirmed via apply-test against `/tmp/testfinal/spec/PERSONA.md` + `spec/OPERATOR.md` |
| AC8 | PASS — 0 lines diff in `src/packages/` | confirmed via `git diff --cached --stat -- src/packages/` (empty) |
| AC9 | PASS — 9 cnos issues spot-checked existing; ROLES.md anchors resolve | confirmed via MCP issue reads + ROLES.md grep |

All 9 ACs PASS independently. β's re-run matches α's self-coherence.

## Implementation-contract conformance (per beta/SKILL.md Rule 7 from cnos#393)

The dispatch contract pinned 7 implementation-contract axes. β walks each:

| Axis | Pinned value | β conformance check | Conforms? |
|---|---|---|---|
| Language | Markdown + unified-diff patches | All 5 deliverables are `.md` / `.patch` files; no other languages introduced | ✓ |
| CLI integration target | None | No code; no CLI surface; no scripts | ✓ |
| Package scoping | `cnos:.cdd/iterations/cross-repo/cn-sigma/sigma-activation-2026-05-22/` | Bundle is at exactly this path; no files outside this dir (except close-out artifacts at `.cdd/unreleased/413/` which are per `CDD.md` close-out shape, not part of the bundle proper) | ✓ |
| Existing-binary disposition | N/A | No existing binary; no removals | ✓ |
| Runtime dependencies | None | Patches require `git apply --recount` (or `patch -p1`) at apply time; these are standard tools, not new runtime deps | ✓ |
| JSON/wire contract | N/A | No JSON / wire artifacts emitted | ✓ |
| Backward compat | No edits to cnos.cdd/cnos.cdr/cnos.cds/cnos.core (hard rule) | AC8 PASS confirms | ✓ |

All 7 axes conform. No implementation-contract drift detected. Behavior-only ACs (AC1–AC9 mechanical) are necessary AND sufficient here because the dispatch contract's axes are not in tension with the AC oracle surface (they are all N/A or trivially conformant for docs-only work).

## Doctrine-locality + case-identification check (per cross-repo/SKILL.md §4)

§4.1 case-identification check:
- LINEAGE.md first paragraph names case (d.2) — ✓
- Bundle file set matches §2.5 case-d row (LINEAGE.md + substantive content; no STATUS; no FEEDBACK.patch unless wanted) — ✓
- LINEAGE schema matches §2.6 case-d sections (Purpose / Source / Bundle contents / Application / Verification after application / What is NOT in scope here / Disposition) — ✓

§4.2 STATUS check: N/A (case (d) carries no STATUS state machine).

§4.3 archival check:
- Source-side bundle: this bundle lives at the cnos side (cnos is the "source" of the feedback patch; cn-sigma is the "target" the cnos session cannot write to). Archival predicate per §2.8.1 case-d row is "the operator effects the application." LINEAGE.md `Disposition` section names this predicate explicitly — ✓
- Target-side mirror: N/A (no cn-sigma-side bundle exists yet; the bundle moves to cn-sigma's awareness via operator action).

§4.4 doctrine-locality check:
- Bundle has no README.md carrying protocol doctrine — ✓
- Protocol doctrine lives only in `src/packages/cnos.cdd/skills/cdd/cross-repo/SKILL.md`, which this bundle cites but does not duplicate — ✓
- LINEAGE.md describes bundle-specific context; patch headers describe per-patch context; anchor doc describes per-rule empirical context. No doctrine sneak-in. — ✓

All four §4 checks PASS.

## Substantive spot-checks

β reads each deliverable beyond the mechanical oracle to confirm substantive correctness:

### LINEAGE.md (D1)

- Case (d.2) cited correctly per `cross-repo/SKILL.md §2.1` row "(d.2) target-repo-exists-but-unreachable" — ✓
- Lifecycle "drafted → operator-applied → archive" matches §2.8.1 case-d row — ✓
- `## Source` section names trigger (operator directive after #403 close at `378a54f0`), reference doctrine (`ROLES.md §4a/§4a.1/§4a.2` + `cross-repo/SKILL.md §2.1`), sibling exemplars (discipline-section-2026-05-19 + agent-activate-skill) — matches §2.6 case-d Source section spec — ✓
- `## Application` section names the apply commands per case-d.2 (operator runs `git apply --recount` from cn-sigma root) — ✓
- `## Verification after application` names the post-apply greps per AC5/AC8-analog reasoning — ✓
- `## What is NOT in scope here` correctly excludes: no direct write to cn-sigma; no cnos package edits; no rewrites of existing cn-sigma sections; no STATUS event; no preempting #404 / #405. — ✓
- `## Disposition` reads "Status: drafted (operator-pending)" — ✓
- Hat-collapse documented (γ+α+β-collapsed-on-δ per `cross-repo/SKILL.md §2.9`-analog) — ✓ (the §2.9 form requires this only for case-c bilateral bundles, but documenting for case-d is over-conformance, not under-conformance)

### PERSONA-additions.patch (D2)

- Canonical header form (From / Date / Subject / blank / prose context / `---` / diff body) per `cross-repo/SKILL.md §2.7` — ✓
- Apply command in header is `git apply --recount PERSONA-additions.patch` — ✓
- Header notes operator may relocate per Continuity rule — ✓
- 6 rules present with verbatim names from issue body D2 spec — ✓
- Each rule names empirical anchor (cnos cycle # + brief context) — ✓
- Citation block at end names 9 cnos cycles (366/376/391/392/393/402/403/404/405) — ✓
- Doctrinal anchors block names `ROLES.md §4a/§4a.1/§4a.2` — ✓
- Cross-reference to OPERATOR-additions.patch present — ✓
- Apply-order note (D2 before D4) present — ✓

### OPERATOR-additions.patch (D3)

- Canonical header form — ✓
- Apply command `git apply --recount OPERATOR-additions.patch` — ✓
- 3 sub-rules with verbatim names from issue body D3 spec — ✓
- Each sub-rule names empirical anchor — ✓
- Implementation-contract 7-axis table reproduced under sub-rule 3 — ✓
- Citations to cnos#384/#366/#376/#393/#403/#408/#409/#410 — ✓
- Cross-reference to PERSONA-additions.patch rules 1 and 2 — ✓

### PERSONA-discipline-receipt-additions.patch (D4)

- Canonical header form — ✓
- Apply command `git apply --recount PERSONA-discipline-receipt-additions.patch` — ✓
- Apply-order note (after D2) present — ✓
- 3 named attacks (simplify-away-truth / avoid-hard-refactors / tiny-only-shipments) with counters — ✓
- TSC-observation-not-metric rule — ✓
- `goal_pressure.expected_goal_progress` field cited (cnos#405 §6 schema) — ✓
- RiskPolicy (cnos#405 §7) cited — ✓
- Receipt-side enforcement subparagraph names V's check predicates — ✓
- Cross-reference to existing `## Discipline` and to discipline-section-2026-05-19 — ✓

### docs/empirical-anchor-cnos-bootstrap-arc.md (D5)

- 10 `## Rule` sections (Rules 1–6 persona; Rules 7–9 operator; Rule 10 discipline-augmentation) — ✓
- Each Rule section has Statement / Cycles table / Lesson / How it lands in Sigma — ✓
- Cycles tables cite cnos issues with merge SHAs where applicable — ✓
- `## What's next for Sigma` names #404 (handoff extraction; Sigma will execute), #405 (CCNF-O + TSC steering; Sigma's long-term stack), v1 deep-role rewrites (deferred) per issue body D5 spec — ✓
- Final sections add value beyond per-rule treatment: Arc synthesis (3 clusters mapping to layers); Why this arc produced persona-level doctrine; What this bundle deliberately does NOT do; Reading order for a future Sigma session; Anchor doc lifecycle — ✓
- Line count: 253 (issue body target ~300–400; AC6 mechanical oracle satisfied at ≥10 rule sections) — non-blocking observation; not a finding (see below)

## Non-blocking observations (no fix required)

1. **Anchor doc line count (253 vs ~300–400 target).** Issue body D5 says "~300–400 lines"; the mechanical AC6 oracle is "≥ 10 sub-sections (one per rule from D2 + D3 + D4) with cycles cited" — strictly satisfied. The ~300–400 line target is aspirational guidance. 253 lines covers all 10 rules with cycles tables + 5 additional synthesis sections; the content is comprehensive. β considers this a non-blocking observation; lifting to a finding would require the issue body to declare the line count as a binding AC, which it does not.

2. **`@@ EOF @@` precedent improvement.** The discipline-section-2026-05-19 precedent shipped patches using `@@ EOF @@` hunk markers which `git apply` rejects as "corrupt patch" (the marker is not valid git unified-diff syntax). This bundle improves on the precedent by shipping proper `@@ -L,M +L,N @@` hunks with placeholder line numbers + trailing-context anchors + `--recount` apply-command instruction. β notes this as a positive observation; the next cross-repo bundle authoring cycle should adopt this pattern (and the cross-repo SKILL.md §2.7 may want to ratify the `--recount` apply-mode + placeholder-line-numbers + trailing-context-anchor pattern as the canonical form for content-anchored patches without exact line knowledge).

3. **Hat-collapse documentation for case (d).** Per `cross-repo/SKILL.md §2.9` the hat-collapse acknowledgment is required for case (c) bilateral bundles. This bundle is case (d.2) and documents the γ+α+β-collapsed-on-δ collapse in LINEAGE.md anyway (over-conformance). The §2.9 doctrine could be extended to formally require hat-collapse acknowledgment for case (d) when the bundle is collapsed-role-authored; this is a protocol-gap observation forwarded as a potential ε signal, not a finding for this cycle.

None of the three observations require fix-rounds. All are positive notes for downstream cycles.

## Implementation-contract observation forwarded (not a finding)

β notes that the 7-axis implementation contract for this docs-only cycle was trivially conformant (5 axes are N/A; 2 are simple "Markdown + unified-diff patches" and the canonical path). The `beta/SKILL.md` Rule 7 check fires meaningfully for code-bearing cycles; for docs-only cycles, the check is structurally low-stakes. This is the design intent (the rule prevents the cnos#389 / cnos#391 Python-vs-Go drift class, which only applies to code work); β confirms the rule operates correctly in the docs-only regime (it doesn't manufacture findings; it confirms conformance trivially).

## R1 verdict

**APPROVED.** All AC1–AC9 PASS independently re-verified. Implementation-contract fully conformant. Cross-repo SKILL.md §4 doctrine-locality + case-identification checks PASS. No findings; no fix-rounds required.

Merge-ready (operator decides merge timing). Bundle is `drafted (operator-pending)` on the cn-sigma side; the cnos-side cycle is closeable as soon as γ files the close-outs and pushes the branch.
