**Verdict:** APPROVED

**Round:** 1
**Fixed this round:** n/a (first round, no prior findings)
**Branch CI state:** no CI on cycle branches — docs-only diff (.md files only; `build.yml` triggers on `main` push only, not `cycle/*`); provisional green
**Merge instruction:** `git merge --no-ff origin/cycle/324` into main with `Closes #324`

| Check | Result | Notes |
|---|---|---|
| Status truth preserved | yes | Issue correctly distinguishes what exists (large all-in-one skill) from target (orchestrator + subskills). No draft behavior described as shipped. |
| Canonical sources/paths verified | yes | All paths resolve: `src/packages/cnos.cdd/skills/cdd/issue/SKILL.md` and four new subskill paths. Root preserved at stable path; no peer references to sections that were removed. |
| Scope/non-goals consistent | yes | Scope: skill refactor + label taxonomy only. Non-goals: no GitHub automation, no CI label enforcement, no structured frontmatter, no internal kata subskill. Diff shows exactly 5 SKILL.md files — no non-goal nouns in ACs. |
| Constraint strata consistent | yes | Hard gate: all 10 CTB v0.1 frontmatter fields required for new subskills. Exception-backed: `artifact_class: reference` + `kata_surface: none` for labels subskill — valid per CTB LANGUAGE-SPEC.md §2 (`none` permitted for non-skill classes). |
| Exceptions field-specific/reasoned | yes | No exception ledger applies here. Debt section in self-coherence names 4 items; none are hard-gate violations. |
| Path resolution base explicit | yes | All paths are repo-root-relative. Root `issue/SKILL.md` preserved at same path; no resolution ambiguity for callers. |
| Proof shape adequate | yes | All 12 ACs carry invariant/oracle/positive/negative/surface. Proof plan names known gaps (GitHub label creation deferred, CI label validation deferred). |
| Cross-surface projections updated | yes | Peer enumeration: `gamma/SKILL.md`, `alpha/SKILL.md`, `cdd/SKILL.md` all reference `issue/SKILL.md` by stable path only — no section references. M5 kata path unchanged. No projection updates required. |
| No witness theater / false closure | yes | This is a skill-only refactor. No checker, runtime, or CI surface is added that would require enforcement evidence. |
| PR body matches branch files | yes | No separate PR body (CDD triadic protocol). `self-coherence.md` serves as branch summary; it matches HEAD state accurately. |

## §2.0 Issue Contract

### AC Coverage

| # | AC | In diff? | Status | Notes |
|---|----|----------|--------|-------|
| AC1 | Root issue skill becomes an orchestrator | yes | PASS | Root SKILL.md is 200 lines, orchestrator-shaped. Label enum absent from root (verified: `| \`bug\`` pattern not in root, only in labels subskill). Contains: core principle, tri formula, subskill load instructions, minimal output pattern, closure rule, handoff checklist, external kata ref. |
| AC2 | Label taxonomy subskill exists | yes | PASS | `src/packages/cnos.cdd/skills/cdd/issue/labels/SKILL.md` exists, contains kind/priority/surface label sections with examples. |
| AC3 | Required kind-label enum is defined | yes | PASS | Labels subskill defines all 8 required kind labels (`bug`, `enhancement`, `docs`, `design`, `test`, `refactor`, `chore`, `tracking`) with definitions. |
| AC4 | Required priority-label enum is defined | yes | PASS | Labels subskill defines P0–P3 with meanings and "exactly one priority label per issue" rule. |
| AC5 | Surface/domain labels optional and minimal | yes | PASS | Labels subskill §Surface/domain labels defines 9 optional labels, collision rule ("must not duplicate a kind label"), ❌/✅ examples. |
| AC6 | Existing issue-contract sections preserved | yes | PASS | All 14 original §3.1–§3.14 rules redistributed to subskills (see §Notes §3.9 observation). All required sections present across the family: problem, impact, status truth, source of truth, scope, non-goals, constraint strata, ACs, proof plan, skills, design constraints, related artifacts, success/closure. |
| AC7 | Detailed rules in focused subskills | yes | PASS | Clean ownership boundaries: labels owns taxonomy, contract owns sections, proof owns ACs/proof-plan, constraints owns strata/exceptions/paths/projections. No cross-subskill rule duplication found. |
| AC8 | Root skill calls subskills | yes | PASS | Frontmatter `calls:` lists all four subskills. Body "When to load each subskill" section names all four with load conditions. |
| AC9 | New subskills have valid frontmatter | yes | PASS | All 10 required CTB v0.1 fields present in all 4 new subskills. `labels` has `artifact_class: reference`, `kata_surface: none` — valid (CTB LANGUAGE-SPEC.md §2 line 67–68: `reference` is a valid non-skill class; `none` permitted for non-skill classes). |
| AC10 | Examples reflect label rules | yes | PASS | 6 examples in labels subskill (≥ 4 required): all use exactly one kind + one priority label. Issue's minimum 4 examples met and exceeded. |
| AC11 | External kata remains available | yes | PASS | Root frontmatter: `kata_surface: external`, `kata_ref: src/packages/cnos.cdd.kata/katas/M5-issue-authoring/`. M5 kata directory confirmed present on main. |
| AC12 | No semantic expansion beyond labels | yes | PASS | Diff: 5 SKILL.md files + self-coherence.md only. No GitHub automation, no CI enforcement, no structured frontmatter, no internal kata subskill. |

### Named Doc Updates

| Doc / File | In diff? | Status | Notes |
|------------|----------|--------|-------|
| `src/packages/cnos.cdd/skills/cdd/issue/SKILL.md` | yes | changed | Root rewritten as orchestrator |
| `src/packages/cnos.cdd/skills/cdd/issue/labels/SKILL.md` | yes | new | Label taxonomy subskill |
| `src/packages/cnos.cdd/skills/cdd/issue/contract/SKILL.md` | yes | new | Contract sections subskill |
| `src/packages/cnos.cdd/skills/cdd/issue/proof/SKILL.md` | yes | new | AC and proof plan subskill |
| `src/packages/cnos.cdd/skills/cdd/issue/constraints/SKILL.md` | yes | new | Constraint sections subskill |
| `src/packages/cnos.cdd.kata/katas/M5-issue-authoring/` | n/a | unchanged | Explicitly out of scope; still present |
| `gamma/SKILL.md`, `alpha/SKILL.md`, `cdd/SKILL.md` | n/a | no update needed | All reference `issue/SKILL.md` by stable path only |

### CDD Artifact Contract

| Artifact | Required? | Present? | Notes |
|----------|-----------|----------|-------|
| `.cdd/unreleased/324/self-coherence.md` | yes | yes | Gap, mode, skills, 12 ACs mapped, 14 rules traced, debt, pre-review gate, review-readiness signal |
| `.cdd/unreleased/324/beta-review.md` | yes | yes | This document |

### Active Skill Consistency

| Skill | Required by | Loaded? | Applied? | Notes |
|-------|-------------|---------|----------|-------|
| `cnos.core/skills/write` | issue §Skills to load | yes | yes | One governing question per artifact; compact, top-down structure visible in all 5 files |
| `cnos.core/skills/design` | issue §Skills to load | yes | yes | One reason to change per file; boundaries match issue's explicit AC7 ownership table |
| `cnos.core/skills/skill` | issue §Skills to load | yes | yes | Full CTB v0.1 frontmatter on all new subskills; `artifact_class` correctly chosen (`reference` for labels, `skill` for contract/proof/constraints) |
| `cdd/review` | issue §Skills to load | yes | yes | AC evidence depth correct; negative cases present in proof subskill; constraint strata respected in constraints subskill |

---

## Architecture Check

| Check | Result | Notes |
|---|---|---|
| Reason to change preserved | yes | Root: one reason (orchestrator shape). Labels: label taxonomy. Contract: sections content. Proof: AC/proof rules. Constraints: strata/exceptions/paths/projections. No file mixes concerns. |
| Policy above detail preserved | yes | Root keeps "when to load" policy; detail in subskills. |
| Interfaces remain truthful | yes | Root `calls` frontmatter accurately reflects delegation. Subskill inputs/outputs match what they teach. |
| Registry model remains unified | n/a | No runtime registry involved. |
| Source/artifact/installed boundary preserved | n/a | Skill-only docs refactor; no runtime or build surface. |
| Runtime surfaces remain distinct | n/a | No runtime surfaces changed. |
| Degraded paths visible and testable | n/a | No degraded paths involved. |

## Notes

**§3.9 redistribution (observation, not a finding):** The original rule §3.9 "Examples must obey the issue's own rules" is distributed across three surfaces rather than appearing as a single explicit rule: (a) root handoff checklist item "Examples obey the rules they are demonstrating," (b) constraints §2.1 rule "exception examples must not contradict hard-gate rules," (c) constraints §3.1 "Hard gates have no exceptions." The substance is fully captured. No content was lost — the distribution reflects the more granular structure the split introduces. β notes this for γ's PRA, not as a merge blocker.
