## §2.0.0 Contract Integrity

| Check | Result | Notes |
|---|---|---|
| Status truth preserved | yes | Issue clearly distinguishes "shipped" vs "NOT NAMED" (planned) states |
| Canonical sources/paths verified | yes | All referenced files exist: review/SKILL.md §3.13, gamma/SKILL.md §scaffold-time, release/SKILL.md §3.8 |  
| Scope/non-goals consistent | yes | No contradictions between ACs and stated non-goals |
| Constraint strata consistent | n/a | No constraint strata defined for docs-only cycle |
| Exceptions field-specific/reasoned | n/a | No exceptions defined |
| Path resolution base explicit | n/a | No path validation being implemented |
| Proof shape adequate | yes | All 4 ACs have proper invariant/oracle/evidence format |
| Cross-surface projections updated | yes | All three target files updated (gamma, review, release SKILL.md files) |
| No witness theater / false closure | yes | Adds real enforcement: peer-enumeration requirements with mechanical steps |
| PR body matches branch files | n/a | No PR body yet; self-coherence.md matches implementation |

## §2.0 Issue Contract

### AC Coverage
| # | AC | In diff? | Status | Notes |
|---|-------|----------|--------|-------|
| AC1 | `cdd/gamma/SKILL.md` gains §Peer enumeration section | ✅ | **Met** | Lines +172-+184: Complete §2.2a with 3-step procedure and honest-claim framing |
| AC2 | `cdd/review/SKILL.md` §3.13 cross-references γ peer-enumeration | ✅ | **Met** | Line +132: Added subsection (d) Gap claims with peer-enumeration reference |  
| AC3 | `cdd/release/SKILL.md` §3.8 rubric names γ peer-enumeration competency | ✅ | **Met** | Lines +337-+338: Added false-gap peer-enumeration clause capping γ axis at B |
| AC4 | Worked example references tsc #36 | ✅ | **Met** | Line +184: Empirical anchor naming tsc cycle #36, cost (1 RC round), and β rescue |

### Named Doc Updates
| Doc / File | In diff? | Status | Notes |
|------------|----------|--------|-------|
| `src/packages/cnos.cdd/skills/cdd/gamma/SKILL.md` | ✅ | **Updated** | Peer enumeration section added with empirical anchor |
| `src/packages/cnos.cdd/skills/cdd/review/SKILL.md` | ✅ | **Updated** | Gap claims subsection added to rule 3.13 |
| `src/packages/cnos.cdd/skills/cdd/release/SKILL.md` | ✅ | **Updated** | False-gap peer-enumeration clause added to §3.8 rubric |

### CDD Artifact Contract
| Artifact | Required? | Present? | Notes |
|----------|-----------|----------|-------|
| `.cdd/unreleased/351/self-coherence.md` | Yes | ✅ | Complete with Gap, Mode, ACs, CDD Trace, review readiness |

### Active Skill Consistency
| Skill | Required by | Loaded? | Applied? | Notes |
|-------|-------------|---------|----------|-------|
| write/SKILL.md | Self-coherence Tier 3 | ✅ | ✅ | All output artifacts are written documents; write principles applied |
| gamma/SKILL.md | Self-coherence Tier 2 | ✅ | ✅ | γ role surface; peer-enumeration section follows γ discipline |
| issue/SKILL.md | Self-coherence Tier 2 | ✅ | ✅ | Issue structure and AC format applied |
| review/SKILL.md | Review process | ✅ | ✅ | Rule 3.13 structure and honest-claim framing applied |
| release/SKILL.md | Review process | ✅ | ✅ | §3.8 rubric structure and grading clause format applied |

## Findings

No findings identified. All contract integrity, issue contract, diff context, and architecture checks pass.

## Diff Context Review

All relevant checks pass:
- ✅ **Multi-format parity:** Peer-enumeration concept consistently described across all three skill files
- ✅ **Authority-surface conflict:** All cross-references correctly point to `gamma/SKILL.md` §2.2a as the authoritative source
- ✅ **Module-truth audit:** New γ peer-enumeration rule is properly symmetric with existing α rule 3.13 honest-claim verification
- ✅ **Architecture leverage:** Addresses root cause systematically (false-gap cycles) rather than treating as one-off patches
- ✅ **Process overhead:** Prevents documented waste (1 RC round cost from tsc cycle #36) with concrete empirical justification

## Architecture Check

Architecture check not active for this docs-only cycle. No runtime architectural boundaries touched.

## CI Status

All required workflows completed successfully on review SHA:
- Build workflow: success

## Notes

Clean docs-only cycle implementing systematic peer-enumeration discipline for γ at scaffold time. Addresses demonstrated failure mode (tsc cycle #36 false-gap costing 1 RC round) with mechanical verification requirements. Implementation is complete, consistent across all three target skill files, and maintains proper authority hierarchy with gamma/SKILL.md §2.2a as canonical source.
