   - Spec requires path-to-component ownership resolution
   - ✅ Aligned

3. **Transitive dependency expansion** (Design lines 101-115 ↔ REQ-3)

   - Spec: MUST expand transitive dependencies
   - ✅ Aligned

4. **Publish policy distinction** (Design lines 78-82 ↔ REQ-5)
   - Design: publishable vs validate-only
   - Spec: explicit publish_policy field
   - ✅ Aligned

5. **Stable/beta parity** (Design lines 117-135 ↔ REQ-7)

---

### 4.4 Rollback Posture Documentation

**Rollback Documentation Verified**:

1. **Proposal** (proposal.md lines 85-91):
   - "Because this proposal is documentation-first, rollback for this change artifact is limited to not applying the graph-backed implementation until confidence is established."
   - ✅ Clear rollback posture for documentation-first phase

2. **Migration Plan** (migration-plan.md lines 13, 28, 42):
   - Phase 0: "Confirm existing manifest/config/workflow state is healthy enough to serve as rollback baseline"
   - Phase 2: "Failure signal: graph data cannot faithfully represent current release behavior or drifts from manifests/config"
   - Phase 4: "Keep validate-only components visible in validation posture without treating them as standalone publish authorities"
   - ✅ Rollback considerations documented for each phase

3. **Tasks** (tasks.md line 43):
   - "4.3 Confirm that rollback posture remains documented for follow-up implementation work that changes live workflows"
   - ✅ Explicit task to verify rollback documentation

**Result**: ✅ Rollback posture is clearly documented

## 5. Documentation Quality Assessment

### Strengths

1. **Comprehensive Coverage**: All 8 requirements documented with 30+ scenarios
2. **Clear Rationale**: Each requirement includes rationale explaining the "why"
3. **Deterministic Semantics**: 5-step resolution algorithm is explicit and unambiguous
4. **Operator-Facing**: Release evidence requirements ensure traceability
5. **Phased Rollout**: Migration plan provides clear exit criteria and rollback points
6. **Terminology Discipline**: Consistent use of key terms across all artifacts
7. **RFC 2119 Compliance**: Proper use of MUST/SHOULD/MAY throughout
8. **Scenario-Driven**: Requirements validated with concrete Given/When/Then scenarios

### Areas of Excellence

1. **Graph Field Definitions**: Complete required and optional field specifications (REQ-1.1, REQ-1.2)
2. **Resolution Algorithm**: 5-step deterministic process with fail-closed behavior (REQ-2)
3. **Transitive Expansion**: Mandatory multi-hop dependency expansion (REQ-3)
4. **Publish Policy**: Clear publishable vs validate-only distinction (REQ-5)
5. **Stable/Beta Parity**: Explicit allowed differences (REQ-7)

## 6. Issues and Risks

### Critical Issues

**None identified** ✅

### Warnings

**None identified** ✅

### Observations

1. **Phase 3 Tasks Deferred**: Tasks 3.1-3.4 (follow-up implementation planning) are intentionally deferred to implementation phase
   - **Impact**: Low - documentation-first phase is complete as intended
   - **Recommendation**: Address in follow-up implementation work

2. **No Executable Graph Yet**: This phase documents the contract but does not create the executable graph file
   - **Impact**: Low - this is the intended scope (documentation-first)
   - **Recommendation**: Phase 2 of migration-plan.md covers executable graph creation

3. **No Workflow Changes**: Live GitHub workflows remain unchanged
   - **Impact**: Low - this is the intended scope (documentation-first)
   - **Recommendation**: Phase 3 of migration-plan.md covers workflow adoption
