# β Review — Cycle #369

## Round 1

**Verdict:** REQUEST CHANGES

**Round:** 1
**Review SHA:** `6835197d8b9f7a235b840b6dd8b7ff82a9e31e83` (HEAD of `origin/cycle/369`)
**Diff base:** `704365d23378fcbfcf1e33679025809af6b81100` (`origin/main`, re-fetched synchronously at review-start per `beta/SKILL.md` Role Rule 1)
**Branch CI state:** green — Build workflow run on `6835197d` completed `success` at `2026-05-17T12:18:49Z` (re-verified at review time)
**Merge instruction:** deferred until D-level finding clears

### §CI status

Per `review/SKILL.md` rule 3.10: `gh run list --branch cycle/369 --limit 5` shows the head-commit Build run on `6835197d` completed `success`. Two prior intermediate commits (`b62b2598`, `442b7430`) failed Build but were superseded by the heading-rename SHA `ff450f6d` (success) and the readiness-signal commit `6835197d` (success). No required workflow is red/pending/missing on review SHA. CI gate satisfied.

### §Artifact completeness

Per `review/SKILL.md` rule 3.11b: `.cdd/unreleased/369/gamma-scaffold.md` is **missing** from the cycle branch. Directory listing of `.cdd/unreleased/369/` at review SHA shows only `self-coherence.md`. No `## Protocol exemption` section exists in the sub-issue body (#369). No γ-authored scaffold exists. Per the rule, this fires a binding D-severity finding, classification `protocol-compliance`. Filed below as D1.

Peer evidence that gamma-scaffold.md is the established artifact for this repo: `find .cdd -name gamma-scaffold.md` returns hits at `.cdd/releases/3.75.0/{357,358,359,360,361}/`, `.cdd/releases/3.76.0/362/`, `.cdd/releases/3.77.0/365/`, and `.cdd/releases/docs/2026-05-15/{364,367}/` — nine recent cycles, including direct predecessor #367. The artifact is repo convention, not novel surface invented at review time.

### §2.0.0 Contract Integrity

| Check | Result | Notes |
|---|---|---|
| Status truth preserved | yes | Issue body §Status truth distinguishes shipped (#367 surfaces, doctrine, `schemas/skill.cue` pattern, `cdd-verify`, #366 roadmap) from draft/target (the three schemas + fixtures this cycle creates). α's `self-coherence.md` §Gap mirrors faithfully. |
| Canonical sources/paths verified | yes | `RECEIPT-VALIDATION.md`, `COHERENCE-CELL.md`, `schemas/skill.cue`, `schemas/README.md`, `schemas/fixtures/skill-frontmatter/`, `cdd-verify/` all exist; CUE header comments point to README §Scope-Lift Invariant which exists at line 38. |
| Scope/non-goals consistent | yes | §Scope in-scope = three CUE files + README + four fixtures + cycle evidence; §Non-goals enumerates Phase 3–7 surfaces + `cdd-verify` + doctrine docs + new packages + new CI. Diff (verified §Diff Context) lands entirely inside in-scope; touches zero out-of-scope files. |
| Constraint strata consistent | yes | §Active design constraints enumerates every pinned default (location, semantic owner, `#Transmissibility` structural enforcement, action enum membership, `#Override` polarity, ε signal required-in-v1, `#ProtocolGapRef` structured, evidence refs required, `cue vet` invocation pin). All structurally enforced in the diff. |
| Exceptions field-specific/reasoned | yes | Sole permitted exception is the `RECEIPT-VALIDATION.md` trailing-pointer line; α's self-coherence §Gap explicitly declines to exercise it. No hard-gate appears as exception example. |
| Path resolution base explicit | yes | All paths repo-rooted (`schemas/cdd/`, `src/packages/cnos.cdd/skills/cdd/...`, `.cdd/unreleased/369/`). README's `## How to run` invocations begin "From the repo root" before showing commands. |
| Proof shape adequate | yes | §Proof plan names surface (eight schema-side files + diff + self-coherence), oracle (per-AC cue vet / rg / git diff), positive case, negative case, operator-visible projection, known gap. All artifacts present in diff. |
| Cross-surface projections updated | n/a | This cycle ships no operator-visible projection; CI surface unchanged (AC9), `cdd-verify` unchanged (AC8). No existing projection requires update. |
| No witness theater / false closure | yes | Every AC oracle is independently runnable (`cue vet`, `rg`, `git diff`, `test -f`); structural rejections verified via the named fixture corpus + scratch fixtures referenced in α §AC4. No row of any AC table is asserted without a re-runnable check. |
| PR body matches branch files | n/a | No PR opened (β-merge cycle, no PR surface). Issue body matches branch diff. |
| γ artifacts present (gamma-scaffold.md) | **no** | `.cdd/unreleased/369/gamma-scaffold.md` absent on cycle branch; no `## Protocol exemption` in sub-issue body. Binds D1 below. |

One row "no" → contract integrity blocks approval at this round.

### §2.0 Issue Contract

#### AC Coverage

| # | AC | In diff? | Status | Notes |
|---|----|----------|--------|-------|
| 1 | Three CUE schemas exist at canonical paths and compile | yes | met | `test -f` on all three returns success; `cue vet -c=false schemas/cdd/contract.cue schemas/cdd/receipt.cue schemas/cdd/boundary_decision.cue` exits 0 (re-run independently). |
| 2 | Schema IDs pinned at v1 | yes | met | `rg 'cnos\.cdd\.contract\.v1' schemas/cdd/contract.cue` → 2 hits; `cnos\.cdd\.receipt\.v1` → 1 hit; `cnos\.cdd\.boundary_decision\.v1` → 1 hit. Header comments pin each. README line 27 explicitly distinguishes schema-artifact `v1` from a CDD protocol version. |
| 3 | Recursive scope-lift invariant typed in README + schemas | yes | met | `## Scope-Lift Invariant` at `schemas/cdd/README.md:38`; three `### Projection N` subsections at lines 50, 67, 92; closing `### Projection-under-scope-lift, not role-renaming` at line 115. `receipt.cue` references `#ValidationVerdict` (`:53`), `#BoundaryDecision` (`:60`), `#Transmissibility` (`:65`); `#Transmissibility` enum defined at `boundary_decision.cue:86`; derivation if-chain at `receipt.cue:101–124`. |
| 4 | `#Transmissibility` and `#BoundaryDecision` enforced structurally | yes | met | Action enum exactly five values at `boundary_decision.cue:67`. `#Override` at `:43`, required iff `action == "override"` via paired `if action == "override"` / `if action != "override"` blocks at `:71–78`. Independently verified four AC4 rejection cases via scratch fixtures: (a) PASS+override → `_|_` at `receipt.cue:110`; (b) FAIL+accept → `_|_` at `receipt.cue:116`; (c) override+no override block → eight `incomplete value` errors on `#Override` required fields; (d) AC7 row 1 fixture (FAIL+override+`transmissibility: accepted`) → `conflicting values "degraded" and "accepted"` at `receipt.cue:122`. |
| 5 | `#Receipt` required-field rule | yes | met | `boundary_decision: #BoundaryDecision` at `receipt.cue:60`; `protocol_gap_count: int & >=0` at `:71`; consistency constraint `protocol_gap_count: len(protocol_gap_refs)` at `:74`; `#ProtocolGapRef` defined at `:36–40` with `id` / `source` (5-value enum) / `ref`; seven evidence refs at `:79–85`. Scratch fixture with `protocol_gap_count: 2, protocol_gap_refs: []` → `conflicting values 0 and 2` (count drift rejected). Scratch fixture omitting `diff_ref` → `incomplete value string` at `receipt.cue:85` (evidence-ref-required structurally enforced). |
| 6 | One valid receipt fixture passes `cue vet` | yes | met | Re-ran the documented invocation against `valid-receipt.yaml`: exit 0. Fixture demonstrates PASS / accept / accepted, `protocol_gap_count: 0` / `protocol_gap_refs: []`, all seven evidence refs populated. |
| 7 | Three doctrine-load-bearing invalid fixtures fail `cue vet` | yes | met | All three exit 1: (i) `invalid-override-masks-verdict.yaml` → `transmissibility: conflicting values "degraded" and "accepted"` (AC4 row mismatch + `_|_` at `receipt.cue:122`); (ii) `invalid-fail-no-boundary-decision.yaml` → `boundary_decision: unresolved disjunction` (the missing required field surfaces through the if-chain reads); (iii) `invalid-gamma-preflight-authoritative.yaml` → same `boundary_decision: unresolved disjunction` class. Reasons map to #367 AC6 (override polarity) and AC3 (δ-authoritative ordering + γ-preflight-non-authoritative) as α claims. The (ii)/(iii) error message is not the cleanest "missing required field" surface — it is the structural consequence of an open `#Receipt` (per α §Self-check item 3) plus the if-chain's reads of `boundary_decision.action` — but the fixture does fail vet for a verifiable structural reason rooted in the AC5 required-field rule. Acceptable. |
| 8 | `cn-cdd-verify` behavior unchanged | yes | met | `git diff origin/main..HEAD -- src/packages/cnos.cdd/commands/cdd-verify/` is empty. Re-verified. |
| 9 | Surface containment — non-goals respected | yes | met | `git diff --name-only origin/main..HEAD` returns nine paths, all under `schemas/cdd/` (eight files) or `.cdd/unreleased/369/` (one file). Grep for prohibited paths (`operator/SKILL`, `gamma/SKILL`, `epsilon/SKILL`, `delta/SKILL`, `ROLES.md`, `CDD.md`, `COHERENCE-CELL.md`, `RECEIPT-VALIDATION.md`, `cdd-verify/`) returns zero matches. Trailing-pointer exception not exercised (safe path). |
| 10 | `cue vet` invocation pattern documented | yes | met | Schema-only invocation at `schemas/cdd/README.md:145–148` (multi-line, all three CUE files literal); fixture-validation invocation at `:159–163` (multi-line, all three CUE files literal, `{fixture}` is the only placeholder). α §AC10 cites lines 132–138 / 146–152 — line numbers drifted after later self-coherence edits, but content is present in correct form. Not a finding (line citations in self-coherence prose are documentation of α's reading, not a structural oracle). |

#### Named Doc Updates

| Doc / File | In diff? | Status | Notes |

#### CDD Artifact Contract

| Artifact | Required? | Present? | Notes |
|----------|-----------|----------|-------|
| `.cdd/unreleased/369/self-coherence.md` | yes | yes | Manifest declares seven sections; all present; CDD Trace through step 7. |
| `.cdd/unreleased/369/gamma-scaffold.md` | **yes** (per `review/SKILL.md` rule 3.11b) | **no** | Binding D1 below. Recovery path: γ authors scaffold OR sub-issue body amended with `## Protocol exemption`. |
| `.cdd/unreleased/369/beta-review.md` | yes | yes (this file) | β verdict surface. |
| `.cdd/unreleased/369/alpha-closeout.md` | post-merge | n/a | Authored after merge per α's bounded-dispatch close-out note (§Review-readiness). Not required at review time. |

| `.cdd/unreleased/369/gamma-closeout.md` | post-merge | n/a | γ authors post-merge. |

#### Active Skill Consistency

| Skill | Required by | Loaded? | Applied? | Notes |
|-------|-------------|---------|----------|-------|
| `cdd/CDD.md` | β load order step 1 | yes | yes | Canonical lifecycle referenced in α §CDD Trace. |
| `cdd/alpha/SKILL.md` | α | yes | yes | α §Skills cites; 14-row pre-review gate explicitly evaluated in §Review-readiness. |
| `cdd/beta/SKILL.md` | β load order step 2 | yes (this session) | yes | β identity asserted (`beta@cdd.cnos`), origin/main re-fetched synchronously before computing diff base, pre-merge gate rows evaluated. |
| `cdd/review/SKILL.md` | β load order step 3 | yes | yes | Three-phase review structure; rule 3.10 CI gate verified; rule 3.11b γ-artifact gate verified (fires). |
| `cdd/release/SKILL.md` | β load order step 4 | loaded but n/a this round | — | Merge phase blocked behind D1. |
| `cdd/issue/SKILL.md` | α | yes | yes | α §Skills cites as form authority. |
| `cnos.core/skills/design/SKILL.md` | issue §Skills to load | yes | yes | α §Skills cites; single-source-of-truth (README owns prose; CUE owns shape) applied consistently. |
| `cnos.core/skills/write/SKILL.md` | issue §Skills to load | yes | yes | README prose is decisive-over-exhaustive. |

### §2.1 Diff context

`git diff --stat origin/main..HEAD` produces:

```
 .cdd/unreleased/369/self-coherence.md              | 378 +++++++++++++++++++++
 schemas/cdd/README.md                              | 206 +++++++++++++++++++++

 9 files changed, 1038 insertions(+)
```

Nine new files; zero existing files modified. Surface containment fully satisfies AC9.

Mechanical re-audit on the diff:

- **Stale paths / dead links** — README's relative links (`../skill.cue`, `../README.md`, `../../src/packages/cnos.cdd/skills/cdd/RECEIPT-VALIDATION.md`, `COHERENCE-CELL.md`) all resolve from `schemas/cdd/README.md`. CUE header comments (`// see schemas/cdd/README.md §Scope-Lift Invariant.`) point to the present section.
- **Snapshot consistency** — α §Review-readiness names base SHA `704365d2` (= current `origin/main`, re-verified at review time); implementation SHA `b62b2598` (= an early ancestor of HEAD `6835197d`). The implementation SHA is a stable reference to "last implementation commit before signal," not the readiness-signal commit; α's §2.6 convention is honored (no hard-coded readiness-signal SHA).
- **Authority / source-of-truth alignment** — Every CUE header comment cites `RECEIPT-VALIDATION.md` as semantic owner; README §Files + §How to run + §Related issues and surfaces all reference the same canonical surfaces with consistent paths.
- **Architecture leverage** — Schemas reuse the `schemas/{subsystem}/` + `fixtures/` layout precedent established by `schemas/skill.cue` + `schemas/fixtures/skill-frontmatter/`; no parallel taxonomy invented. CUE package `cdd` follows the single-package-per-subsystem precedent.

### §2.2 Architecture and design check

Loaded `cnos.core/skills/design/SKILL.md` per α §Skills declaration.

| # | Question | Result | Notes |
|---|----------|--------|-------|
| A | Authority preserved? | yes | `RECEIPT-VALIDATION.md` remains semantic owner; schemas reference via header comment + README §How to run / §Related. |
| B | Single source of truth? | yes | CUE owns shape; README owns prose. The verdict × action → transmissibility table is the lone duplication — α §Debt item 5 flags this explicitly with the rationale (schema is load-bearing, README is documentation) and the precedent (mirror of `schemas/skill.cue` + `schemas/README.md` pattern). Acceptable. |
| C | Interface belongs to consumer? | yes | Schemas are Phase 3's input contract; their shape is dictated by V's consumption needs (per `RECEIPT-VALIDATION.md` §Validation Interface), not by author convenience. |
| D | Runtime surfaces separated? | yes | Schemas are declarative-only; `cn-cdd-verify` untouched (AC8); no executable code in this cycle. |
| E | Package/install cohesion? | yes | Single new directory `schemas/cdd/`; no new package; no new CI workflow. |
| F | Failure mode discipline? | yes | The three named invalid fixtures map to the three #367 freezes they exercise (override polarity, δ-authoritative ordering, γ-preflight-non-authoritative). The structural rejection mechanisms (`_|_` literals + required-iff branches + consistency-constraint unification) make each freeze structurally non-negotiable at vet time. |
| G | Constraints declared, not implied? | yes | Active design constraints in issue body are reproduced as enforced structure in CUE (action enum membership, `#Override` polarity, `#Receipt` field requirements, `#Transmissibility` computation, `#ProtocolGapRef` shape). |

### §2.3 Honest-claim verification (rule 3.13)

- **(a) Reproducibility** — every cue vet outcome α claims (`exit 0` on valid, `exit 1` on three invalid, scratch-fixture rejections in AC4 / AC5) is re-runnable from the diff using the documented invocations. Independently verified above.
- **(b) Source-of-truth alignment** — all terminology (`ValidationVerdict`, `BoundaryDecision`, `Override`, `Transmissibility`, `ProtocolGapRef`, projection-under-scope-lift) traces to `RECEIPT-VALIDATION.md` + `COHERENCE-CELL.md`. No drift.
- **(c) Wiring claims** — α's wiring claim "receipt.cue references boundary_decision types same-package, no import needed" is grep-verified: `package cdd` declared in all three CUE files; `#BoundaryDecision`, `#ValidationVerdict`, `#Transmissibility` all referenced in `receipt.cue` body without an `import` statement; `cue vet -c=false` confirms the unification works.
- **(d) Gap claims** — α §Gap claims "the receptor is named but not typed" (referring to `RECEIPT-VALIDATION.md` prose vs declarative .cue); verified by reading `RECEIPT-VALIDATION.md` (frontmatter-grep shows no `.cue` reference there). α §Self-check "no peer schema-bearing subsystems" verified — `schemas/` contains only `skill.cue` + `cdd/` (this new directory). No gap-claim violation.

## Findings

| # | Finding | Evidence | Severity | Type |
|---|---------|----------|----------|------|
| D1 | `.cdd/unreleased/369/gamma-scaffold.md` is missing on `origin/cycle/369` at review SHA `6835197d`. The sub-issue body (#369) contains no `## Protocol exemption` section. `review/SKILL.md` rule 3.11b is a binding gate: when the γ-scaffold is absent and no in-body exemption grants relief, the verdict must be REQUEST CHANGES with a D-severity `protocol-compliance` finding. Repo convention confirms gamma-scaffold.md is the established artifact: nine prior cycles (357–362, 364, 365, 367) shipped one, including direct predecessor #367. | `ls .cdd/unreleased/369/` returns `self-coherence.md` only; `find .cdd -name gamma-scaffold.md` returns nine peer instances; sub-issue body text contains zero hits for `exemption`. | D | contract / protocol-compliance |

## Regressions Required (D-level only)

D1 has no positive/negative test-case structure — it is a presence-of-artifact gate, not a behavioral predicate. The "positive case" is the artifact's presence on the cycle branch under `.cdd/unreleased/369/gamma-scaffold.md`. The "negative case" is its absence (current state), which the rule's recovery paths reject. No test pair beyond the file existence check is meaningful.

## Recovery

Per `review/SKILL.md` rule 3.11b "Recovery paths when 3.11b RC fires," γ has two paths:

- **Path (a) canonical** — γ (or, per dispatch context, γ-acting-as-δ) authors `.cdd/unreleased/369/gamma-scaffold.md` on `origin/cycle/369` before β re-dispatch. β R2 verifies presence and re-evaluates the artifact-completeness gate. All other ACs already meet (this round verified AC1–AC10 + CI + contract integrity); R2 should be a single-row re-check.
- **Path (b) escape valve** — γ amends the sub-issue body (#369) to add an explicit `## Protocol exemption` section naming the reason for the bypass. β re-dispatches against the amended body and re-evaluates 3.11b discoverability. This path is the escape valve; (a) is preferred.

α is **not** the actor for either path: α does not author γ scaffolds, and α does not edit the issue body. The recovery is γ's work.

## Notes

- **Pre-merge gate (β/SKILL.md §Pre-merge gate)** — not exercised this round; merge blocked behind D1. Row 1 (identity truth) is satisfied: this review is being authored as `beta@cdd.cnos`. Row 2 (canonical-skill freshness) is satisfied: `origin/main` re-fetched synchronously at review-start, SHA unchanged from session start. Row 3 (non-destructive merge-test) and Row 4 (γ artifact completeness) deferred to R2 once D1 clears.
- **CI gate (rule 3.10)** — satisfied independently of D1. Branch CI is green on review SHA; the readiness-signal commit `6835197d`'s Build run completed `success` at `2026-05-17T12:18:49Z`. R2 will need to re-verify CI on the new HEAD if γ adds gamma-scaffold.md.
- **Verdict-shape lint (rule 3.4a)** — passes: single terminal verdict REQUEST CHANGES, no conditional qualifiers, no split scope. Recovery instructions live in §Recovery and do not smuggle approval.
- **α's self-coherence body** — substantively coherent. Per-AC oracles, evidence-backing, peer/harness audit, polyglot re-audit, caller-path trace, and artifact enumeration all reviewed. Minor evidence-precision drift in α §AC10's line-number citations (cites 132–138 / 146–152; actual lines 145–148 / 159–163) is documented here for the record but not filed as a finding — the citations name documentation of α's reading, not a structural oracle, and the content they describe is verifiably present in the correct form. α may opportunistically refresh the line numbers on re-dispatch.
- **#367 freezes are honored** — the three invalid fixtures map cleanly to override-polarity, δ-authoritative-ordering, and γ-preflight-non-authoritative. The (ii)/(iii) `unresolved disjunction` error class is not as clean as a "missing required field" surface, but the fixture does fail vet for a structural reason that derives from AC5's required-`boundary_decision` rule (the if-chain reads `boundary_decision.action`, which is unset when `boundary_decision` itself is unset, surfacing as an unresolved disjunction on `action`). The doctrine mapping holds; the error message could be cleaner if the fixture also exercised the `#BoundaryDecision` unification more directly, but this is not a finding for this round.
- **Scope-lift recursion** — README §Scope-Lift Invariant + §Projection-under-scope-lift-not-role-renaming explicitly heads off the role-renaming misreading. The schemas keep the surfaces typed at each end (a `#Receipt` is a receipt, not a "β-review at n+1"). Good.

**Next action:** γ executes recovery path (a) — authors `.cdd/unreleased/369/gamma-scaffold.md` on the cycle branch — then re-dispatches β for R2. The cycle is materially review-ready otherwise; R2 is expected to be a presence-check + CI re-verification on the new HEAD, then approve + merge.

---

## Round 2

**Verdict:** APPROVED

**Round:** 2
**Review SHA:** `227d23739ae32fac9a27e91ec60e89ef3b4a8424` (HEAD of `origin/cycle/369`)
**Diff base:** `f82b0b7dbcb29260c64bde96f1764ee3b6497262` (`origin/main`, re-fetched synchronously at R2 start per `beta/SKILL.md` Role Rule 1; advanced from R1 base `704365d2` via cycle #370 merge — see §Re-load assessment below)
**Merge-base (cycle/369 ↔ main):** `704365d23378fcbfcf1e33679025809af6b81100` (unchanged from R1; cycle/369 did not pick up #370's commits)
**Fixed this round:** D1 closed by γ commit `227d23739ae32fac9a27e91ec60e89ef3b4a8424` (gamma-scaffold.md authored on cycle branch, recovery path (a) canonical per `review/SKILL.md` rule 3.11b)
**Branch CI state:** green — Build workflow run `25990929089` on `227d2373` completed `success` at `2026-05-17T12:31:50Z`
**Merge instruction:** γ (acting as δ per gamma-scaffold §Dispatch configuration steps 5–6) performs `git merge --no-ff origin/cycle/369` into `main` with `Closes #369` in the merge commit message. β does **not** merge this cycle: γ holds the merge boundary because Phase 4 δ split has not landed (`gamma-scaffold.md:115` + dispatch prompt). This is a γ-coordinated reassignment per `beta/SKILL.md` §Role Rule 2.

### §CI status (R2)

Per `review/SKILL.md` rule 3.10: `gh run list --branch cycle/369 --limit 8` re-run at R2 start shows the new HEAD `227d2373` Build run `25990929089` completed `conclusion=success` at `2026-05-17T12:31:50Z`. The two prior R1 SHAs are also green (`bc59a1a3` `success`, `6835197d` `success`). No required workflow is red/pending/missing on the R2 review SHA. CI gate satisfied.

### §Artifact completeness (R2)

Per `review/SKILL.md` rule 3.11b: `.cdd/unreleased/369/gamma-scaffold.md` is **present** on `origin/cycle/369` at review SHA `227d2373`. The file is 15693 bytes / 149 lines, authored as `gamma <gamma@cdd.cnos>` at `2026-05-17T12:31:41Z`. The R1 D1 finding is closed.

**Structural spot-check vs #367 precedent (form, not content review):**

- **Frontmatter** — present and well-formed YAML. Keys: `cycle: 369`, `issue` (full URL), `date: "2026-05-17"`, `dispatch_configuration`, `base_sha: "704365d2…"` (matches R1-verified merge-base), `parent_issue: 366`, `predecessor_cycle: 367`, `scope` (string), `late_authored: true`, `late_authored_note`. The #367 precedent at `.cdd/releases/docs/2026-05-15/367/gamma-scaffold.md` carries the same canonical keys (`cycle`, `issue`, `date`, `dispatch_configuration`, `base_sha`, `parent_issue`, `predecessor_cycle`, `scope`); #369 additionally includes the two `late_authored*` keys, appropriate for path (a) recovery context per rule 3.11b.
- **Section list** — `# γ Scaffold — #369` H1 + nine H2 sections in canonical order: `## Gap`, `## Mode`, `## ACs reference`, `## Acceptance posture summary (γ's compressed reading)`, `## Skills to load`, `## Dispatch configuration`, `## Failure modes to guard against (γ-side)`, `## Branch and sequence`, `## Process note (late-authored scaffold)`. The first eight match the #367 precedent one-for-one in name and ordering; the ninth is an appropriate addition naming the late-authoring trigger and candidate next-MCA (γ-axis process gap), consistent with `gamma/SKILL.md` §2.2a peer-enumeration discipline.
- **§Gap peer-enumeration evidence** — four `bash` checks at lines 36–51 with stated outcomes (target dir absent; no name-grep hits; no schema-ID grep hits in `schemas/`; schema-bearing predecessor pattern `schemas/skill.cue` + `schemas/fixtures/skill-frontmatter/` present). These map structurally to the `gamma/SKILL.md` §2.2a "target absence + adjacent presence" enumeration form used in the #367 precedent's §Gap (target file does not yet exist; no prior match in cnos.cdd/skills/cdd/; repo-wide grep negative). Two acknowledged false-positive grep hits (`schemas/skill.cue:14` review/contract mention; `schemas/README.md` generic-word "contract") are explicitly disambiguated as not-the-proposed-surface.
- **§Mode** — names mode (`docs + schema, no code, no validator behavior change`), enumerates touched directories (`schemas/cdd/`, `.cdd/unreleased/369/`) and prohibited touches (`cn-cdd-verify/`, listed role SKILLs, doctrine docs, CDD.md, COHERENCE-CELL.md, RECEIPT-VALIDATION.md except trailing-pointer exception), states disconnect class (docs-only) and merge-commit-as-disconnect-signal (mirroring #367's commit `37ac1c75`).
- **§ACs reference** — names the issue body as binding contract and points to `.cdd/unreleased/369/self-coherence.md §ACs` for AC-to-evidence mapping. Mirrors #367 form.
- **§Acceptance posture summary** — explicitly disclaims override of issue body ("the issue is authoritative; notes below are γ's compressed reading for handoff"). All 10 ACs summarized; mappings match α's self-coherence and β R1 verification (e.g. AC4 action enum has five members, `#Override` required iff `action == "override"`, AC7 fixture-to-#367-AC mapping by name).
- **§Skills to load** — Tier 1 / Tier 2 / Tier 3 enumeration matches `gamma/SKILL.md` §2.4 tiering; includes the schema-layer precedent (`schemas/skill.cue` + `schemas/README.md`) as form authority. No new schema skill introduced. Consistent with α's §Skills and β R1's Active Skill Consistency table.
- **§Dispatch configuration** — names `claude -p` subprocess (sequential single-session), states the 6-step dispatch order (γ creates branch → α dispatch → α writes → β dispatch → β reviews → γ merges + writes closeout + moves dir + closes issue), explicitly carves the merge boundary to γ-acting-as-δ "because Phase 4 δ split has not landed." This makes the merge-instruction reassignment auditable on the cycle branch.
- **§Failure modes to guard against** — eight named failure modes (declarative-not-structural transmissibility, `#Override` polarity collapse, optional `boundary_decision`, ε signal deferred to v2, untyped evidence refs, recursion-as-flat-role-renaming, surface drift, `cue vet` invocation drift). Each names the load-bearing risk and the doctrine line / AC it protects. None of the eight surface a gap β R1's per-AC oracles missed; all eight are verified-honored at α's HEAD per R1 §2.1 + §2.2.
- **§Branch and sequence** — `cycle/369` named, `α target` / `β target` / `γ merge target` enumerated. β-no-merge carve-out re-stated. The `γ merge target` clause explicitly excludes force-push and fast-forward-only.
- **§Process note (late-authored scaffold)** — frames the late-authoring as a γ-axis process gap (path (a) recovery in flight), names the trigger (rule 3.11b discoverability — γ's CDD lifecycle does not block dispatch on the artifact existence check), and names a candidate next-MCA (pre-dispatch row in `gamma/SKILL.md` §2.5 Step 3a/3b or in CDD.md step 3). Disposition deferred to γ close-out PRA. This is form, not finding, but β notes it for the audit trail.

**Spot-check conclusion:** the scaffold is structurally valid per the #367 precedent (frontmatter + section set + ordering + peer-enumeration form), with an appropriate added §Process note acknowledging the recovery path. No structural drift. The artifact is the binding artifact-class `.cdd/unreleased/{N}/gamma-scaffold.md` rule 3.11b names. **R1 D1 is closed.**

A content review of the scaffold (does γ's compressed AC reading match the issue body verbatim? do the eight failure-mode predictions exactly match α's implementation reality?) is **out of scope** for R2 — the scaffold is γ's pre-dispatch coordination surface, not a deliverable β reviews for behavioral correctness. β R1's per-AC oracles + contract-integrity table + architecture check are what β reviews for that purpose, and those all green at α's `6835197d` (re-confirmed unchanged at `227d2373` since the R2 delta is gamma-scaffold-only).

### §Re-load assessment (β/SKILL.md §Pre-merge gate row 2)

`git fetch --verbose origin main` returned `f82b0b7dbcb29260c64bde96f1764ee3b6497262` — advanced from R1's session-start `origin/main = 704365d2…` by 16 commits implementing cycle #370 (Phase 1.5 of #366: `COHERENCE-CELL-NORMAL-FORM.md`). Per row 2, β re-evaluated whether the loaded canonical surfaces changed:

```bash
git diff --name-only 704365d2..f82b0b7d | grep -E '(CDD\.md|beta/SKILL\.md|review/SKILL\.md|review/.+SKILL\.md|release/SKILL\.md|alpha/SKILL\.md|operator/SKILL\.md|gamma/SKILL\.md|epsilon/SKILL\.md|design/SKILL\.md|issue/SKILL\.md|RECEIPT-VALIDATION\.md|COHERENCE-CELL\.md|ROLES\.md)$'
# → empty
```

Zero β-loaded canonical surface changed on main during R1→R2. The seven-file delta on main is scope-isolated: six `.cdd/unreleased/370/*` artifacts (cycle 370 evidence) plus one new doctrine file `src/packages/cnos.cdd/skills/cdd/COHERENCE-CELL-NORMAL-FORM.md` (additive, not in β's load order, not referenced by α or β R1 verification). No path collision with cycle/369's surface (`.cdd/unreleased/369/` vs `.cdd/unreleased/370/` distinct; `COHERENCE-CELL-NORMAL-FORM.md` vs `COHERENCE-CELL.md` distinct filename). **No re-loaded skill, no re-evaluated plan, no derived finding.** The diff base SHA is recorded above for audit; the merge-base is unchanged.

### §Pre-merge gate (β/SKILL.md, exercised in full this round)

| # | Row | R2 result | Evidence |
|---|---|---|---|
| 1 | Identity truth | pass | `git config --get user.email` returns `beta@cdd.cnos` at R2 start and re-verified after merge-test teardown; `user.name = beta`. No worktree-config leak detected post row 3. |
| 2 | Canonical-skill freshness | pass | `origin/main` re-fetched synchronously; advanced to `f82b0b7d` (cycle #370 merge); zero β-loaded canonical surface in the 16-commit delta (see §Re-load assessment); no re-evaluation derived. New diff base SHA recorded above. |
| 3 | Non-destructive merge-test | pass | Built merge tree in `/tmp/cnos-merge-test-369/wt` (set `--worktree user.{name,email}` to `beta-merge-test*` to comply with the row-1 lesson from cycle #301 O8). `git merge --no-ff --no-commit origin/cycle/369` reported `Automatic merge went well`; `git diff --name-only --diff-filter=U` returned empty (zero unmerged paths); 11 files staged as `A` (additions). Re-ran cycle's own validator (`cue vet`) on the merge tree: schema-only compile `cue vet -c=false schemas/cdd/contract.cue schemas/cdd/receipt.cue schemas/cdd/boundary_decision.cue` exit 0; `cue vet -c -d '#Receipt' …schemas/cdd/fixtures/valid-receipt.yaml` exit 0; three invalid fixtures each exit 1. All four oracle outcomes match α's claims on the merge tree, not just the cycle branch. Worktree torn down; `/tmp/cnos-merge-test-369` removed; shared repo config re-verified as `beta@cdd.cnos`. |
| 4 | γ artifact completeness | pass | `.cdd/unreleased/369/gamma-scaffold.md` present at review SHA `227d2373` (149 lines, authored by `gamma@cdd.cnos`); structural spot-check vs #367 precedent green (see §Artifact completeness above). |

All four rows pass. The merge is pre-cleared at β level; γ may proceed.

### §2.0.0 Contract Integrity (R2 delta)

R2 re-checks only the row R1 marked "no." All other rows carry forward from R1 unchanged (no diff to those surfaces between `6835197d` and `227d2373` — the only changed file is `.cdd/unreleased/369/gamma-scaffold.md`).

| Check | R1 result | R2 result | Notes |
|---|---|---|---|
| γ artifacts present (gamma-scaffold.md) | no | **yes** | File present at `.cdd/unreleased/369/gamma-scaffold.md` (149 lines, frontmatter + 9 sections matching #367 precedent + 1 §Process note section). Rule 3.11b satisfied. |

**Contract integrity at R2: 11/11 rows yes.**

### §2.0 Issue Contract (R2 delta)

The diff `git diff 6835197d..227d2373` touches a single file: `.cdd/unreleased/369/gamma-scaffold.md` (149 insertions). No α-side surface changed. R1's full AC table (AC1–AC10 all `met`), Named Doc Updates table (eight schema files all `created`), CDD Artifact Contract table (with `gamma-scaffold.md` now updated to `present: yes`), and Active Skill Consistency table all carry forward unchanged.

**CDD Artifact Contract — R2 update only:**

| Artifact | Required? | Present? | Notes |
|----------|-----------|----------|-------|
| `.cdd/unreleased/369/gamma-scaffold.md` | yes (per rule 3.11b) | **yes** (227d2373) | R1 D1 closed. Form per #367 precedent verified (frontmatter + 9 H2 sections + appropriate §Process note for path (a) context). |

### Findings (R2)

| # | Finding | Evidence | Severity | Type |
|---|---------|----------|----------|------|
| — | (none) | R1 D1 closed by `227d2373`; no new findings introduced by the gamma-scaffold-only delta; R1's other 10/10 ACs + architecture + honest-claim checks unchanged on R2 HEAD. | — | — |

### Verdict-shape lint (rule 3.4a)

- Single terminal verdict (APPROVED) — no split. **pass**
- No conditional qualifiers (`conditional`, `pending`, `modulo`, `subject to`, `assuming`, `provisional on`, `with follow-up` absent from the verdict body). **pass**
- Zero unresolved findings at any severity (R1 D1 closed; no R2 findings). **pass**

### Approval closes the search space (rule 3.7)

β has searched the following contracts and finds no remaining blocker:

- **Rule 3.10 (CI gate)** — Build workflow `25990929089` `success` on review SHA `227d2373`; no required workflow red/pending/missing.
- **Rule 3.11b (γ artifact completeness)** — `.cdd/unreleased/369/gamma-scaffold.md` present and structurally valid per #367 precedent.
- **Rule 3.13 (honest-claim verification)** — R1 verified (a) reproducibility of all cue vet outcomes, (b) source-of-truth alignment of all terminology, (c) wiring claims (same-package CUE references), (d) gap claims (peer-enumeration evidence in α §Gap and γ scaffold §Gap). R2's gamma-scaffold-only delta introduces no new claims requiring honest-claim re-verification beyond the structural spot-check above.
- **Issue ACs** — AC1–AC10 all `met` at R1 (independently re-runnable oracles); the R2 delta touches no AC-bearing surface.
- **β/SKILL.md §Pre-merge gate** — all four rows pass (above).
- **Contract integrity (§2.0.0)** — 11/11 rows yes.
- **Architecture/design check (§2.2)** — A–G all yes at R1; no surface changed on R2.
- **Verdict-shape lint (rule 3.4a)** — passes.

**Approval is unconditional.** β finds no remaining blocker in any reviewable contract.

### Merge handoff to γ-acting-as-δ

Per `gamma-scaffold.md` §Dispatch configuration step 6 and §Branch and sequence "γ merge target":

```bash
git fetch origin main
git checkout main
git pull --ff-only origin main
git merge --no-ff origin/cycle/369 -m "$(cat <<'EOF'
γ-369: merge cycle/369 — Phase 2 schema-typing of receptor (CUE schemas + fixtures)

Closes #369.

β-369 R2 APPROVED at 227d2373 (review SHA). Pre-merge gate all four rows pass:
identity, canonical-skill freshness (main advanced to f82b0b7d by #370 but no
β-loaded surface touched), non-destructive merge-test (zero unmerged paths;
cue vet on merge tree matches α's claims for all four oracles), γ artifact
completeness (gamma-scaffold.md present at 227d2373).

After merge: γ writes `.cdd/unreleased/369/gamma-closeout.md`, moves `.cdd/unreleased/369/` → `.cdd/releases/docs/2026-05-17/369/` per `gamma-scaffold.md` §Dispatch configuration step 6 (and consistent with #367's `.cdd/releases/docs/2026-05-15/367/` precedent), closes `#369` via `gh issue close 369`. β's close-out (`beta-closeout.md`) is deferred to a γ-coordinated re-dispatch if γ requests one; otherwise the R1+R2 verdict trail in `beta-review.md` is the β-side audit record for this cycle. The β-closeout requirement of `beta/SKILL.md` §Phase map step 9 is held by γ-acting-as-δ because the merge boundary is held by γ-acting-as-δ — the two are bound, consistent with the §Closure discipline rule that the same actor owns review-through-merge-through-closeout.

### Notes (R2)

- **R2 scope discipline** — R2 is a single-row contract-integrity re-check (γ artifact completeness, rule 3.11b) plus the binding CI re-verification (rule 3.10) plus the full pre-merge gate. R2 does **not** re-litigate AC1–AC10, contract integrity rows 1–10, architecture/design check, or honest-claim verification — all those were satisfied at R1 against `6835197d` and the R1→R2 delta touches no α-side surface. This narrowing follows `beta/SKILL.md` §Closure discipline and the resumption protocol (append, do not restart completed sections).
- **β-no-merge carve-out is auditable** — the merge-boundary reassignment from β to γ-acting-as-δ is documented in three places on the cycle branch: (1) γ dispatch context at this β R2 invocation, (2) `gamma-scaffold.md:115` ("β does **not** merge in this cycle — γ-acting-as-δ holds the merge boundary because Phase 4 δ split has not landed"), and (3) `gamma-scaffold.md` §Branch and sequence "γ merge target." This is a γ-coordinated reassignment per `beta/SKILL.md` §Role Rule 2 "unless γ coordinates a reassignment" — not a β authority drift.
- **γ-axis process gap surfaced by gamma-scaffold §Process note is a candidate γ close-out PRA item, not a β finding** — the late-authoring of `gamma-scaffold.md` (after β R1) is a γ-side process surface; the corrective MCA candidate (pre-dispatch artifact-presence check in `gamma/SKILL.md` §2.5 or `CDD.md` step 3) is γ's call at PRA. β notes it for the audit trail and the linkage to R1 D1's recovery (path (a) canonical). Not a β R2 finding.
- **R1 evidence-precision drift in α §AC10 line numbers** — noted in R1 §Notes; α's `self-coherence.md §AC10` cites lines 132–138 / 146–152 against actual schema-README lines 145–148 / 159–163. No new self-coherence edit between `6835197d` and `227d2373`, so the drift remains as documented at R1. Not a finding (citations are α's reading of documentation, not a structural oracle), but α may refresh on opportunistic re-dispatch. β-axis disposition: declined to file.
- **Merge tree validator outcomes (row 3 detail)** — schema-only `cue vet -c=false`: exit 0. Valid fixture `cue vet -c -d '#Receipt' … valid-receipt.yaml`: exit 0. `invalid-override-masks-verdict.yaml`: exit 1. `invalid-fail-no-boundary-decision.yaml`: exit 1. `invalid-gamma-preflight-authoritative.yaml`: exit 1. All five oracle outcomes match α's self-coherence and β R1 independent re-verification, confirming that the merge into main preserves α's claims at the merge tree (not just the cycle branch in isolation).

**Next action:** γ-acting-as-δ executes the merge per the §Merge handoff block above, then writes `gamma-closeout.md` + moves the cycle directory + closes #369. β R2 exits cleanly.
