## Findings

| # | Finding | Evidence | Severity | Type |
|---|---------|----------|----------|------|
| F1 | CI failure blocks merge | CDD artifact ledger validation (I6) job failed with exit code 1 on commit 70ae4076. Summary: 193 passed, 67 failed, 26 warnings. | B | mechanical |

## CI Status

**Branch:** cycle/328  
**Latest run:** 25756444611  
**Status:** failed  
**Conclusion:** failure  
**Failed job:** CDD artifact ledger validation (I6)  
**Exit code:** 1

The CI failure is **expected behavior** - the new CDD artifact checker is correctly identifying missing historical artifacts across existing cycle directories. However, per review rule 3.10, CI must be green on the review SHA before approval.

## Next Steps

This is a B-severity mechanical finding that must be resolved before merge. The checker implementation appears correct - it's finding genuine gaps in historical CDD artifacts. The implementation needs to either:

1. Add exception handling for known historical gaps, or  
2. Backfill missing historical artifacts where evidence exists, or
3. Adjust the checker logic to handle the current repository state

α should investigate the specific failures and determine the appropriate path forward.

**Status:** Awaiting α fix round on cycle/328

**Round:** R2  
**Fixed this round:** cf746dad (epoch-based enforcement implementation)  
**Base SHA:** 5a9cfe2d (origin/main)  
**Head SHA:** 71cc76c0 (α-328: fix-round R1 close-out)  
**Branch CI state:** red (CDD artifact ledger validation I6 - test fixtures failed)  
**Merge instruction:** Cannot merge until CI green

## §2.0.0 Contract Integrity

| Check | Result | Notes |
|---|---|---|
| Status truth preserved | yes | Fix-round accurately describes epoch-based enforcement approach |

| Scope/non-goals consistent | yes | Approach maintains validation scope while handling legacy cycles |
| Constraint strata consistent | yes | Clear distinction between legacy (warnings) vs current (enforcement) |
| Exceptions field-specific/reasoned | yes | Legacy exception handling with proper YAML structure |
| Path resolution base explicit | yes | Base SHA 5a9cfe2d recorded, head SHA 71cc76c0 verified |

| Cross-surface projections updated | yes | Exception handling integrated into checker logic |
| No witness theater / false closure | yes | Warnings vs failures distinction is real and testable |
| PR body matches branch files | n/a | Issue-based cycle |

## Findings

| # | Finding | Evidence | Severity | Type |
|---|---------|----------|----------|------|
| F2 | CI failure blocks merge | Test fixtures step failed in CDD artifact ledger validation (I6) job. Main artifacts check now passes (184 passed, 0 failed, 106 warnings), but "Run test fixtures" step failed with "Incomplete triadic cycle test FAILED". Exit code 1. | B | mechanical |

## CI Status

**Branch:** cycle/328  
**Latest run:** 25757631930  
**Status:** completed  
**Conclusion:** failure  
**Failed job:** CDD artifact ledger validation (I6)  
**Failed step:** "Run test fixtures"  
**Exit code:** 1

**Analysis:** α's epoch-based enforcement fix successfully resolved F1 - the main CDD artifact validation now passes with 0 failures (184 passed, 106 warnings). However, the test fixtures contain a bug causing "Incomplete triadic cycle test FAILED", which produces CI exit code 1 and blocks merge per rule 3.10.

## R2 Assessment

**F1 Resolution:** ✅ RESOLVED - Epoch-based enforcement successfully converts legacy artifact gaps from failures to warnings. Main artifact validation passes.

**New Issue:** F2 - Test fixture implementation bug blocks CI green despite successful artifact validation.

## Next Steps

α should investigate the test fixture failure in `src/packages/cnos.cdd/commands/cdd-verify/test-fixtures.sh` and fix the "Incomplete triadic cycle test" to align with the epoch-based enforcement logic.

**Status:** Awaiting α fix round R2 on cycle/328

**Verdict:** APPROVED

**Round:** R3  
**Fixed this round:** 5024740a (test fixture alignment), 5211bc64 (R2 close-out), 595d0699 (review-readiness signal)  
**Base SHA:** 5a9cfe2d (origin/main at session start)  
**Head SHA:** 595d0699 (current cycle/328 head)  
**Branch CI state:** green (Build workflow conclusion: success)  
**Merge instruction:** `git merge cycle/328` into main with `Closes #328`

| F1 | CI failure blocks merge | Fixed by epoch-based enforcement (cf746dad) - legacy cycles get warnings instead of failures | B | ✅ RESOLVED |
| F2 | Test fixture failure blocks merge | Fixed by aligning fixture expectations with epoch enforcement (5024740a) - moved to released version directory | B | ✅ RESOLVED |

## CI Status

**Branch:** cycle/328  
**Latest run:** Build workflow for commit 595d0699  
**Status:** completed  
**Conclusion:** success  
**All required workflows:** ✅ green

CI gate per rule 3.10: ✅ PASSED - all required workflows green on review SHA.

## Verdict Analysis

**Contract integrity:** ✅ PASSED - All contract checks pass, no contradictions between issue/implementation/docs.

**Implementation review:** ✅ PASSED - All 12 ACs met with concrete evidence, CDD checker validates current contract, CI integration complete.

**Architecture check:** ✅ PASSED - Clear separation of concerns (release gate vs repo validation), appropriate epoch-based enforcement for legacy cycles, proper exception handling.

**Evidence depth:** ✅ ADEQUATE - Every AC maps to specific commits and verifiable behavior. Test fixtures demonstrate actual checker operation.

**No remaining incoherence:** After F1/F2 resolution, implementation is coherent and ready for integration.

## Approval Scope

This approval covers:
- Updated CDD artifact checker with current layout validation
- Repository-wide artifact ledger validation in CI  
- Test coverage with positive/negative fixtures
- Documentation for local usage
- Exception handling for historical gaps
- Epoch-based enforcement distinguishing legacy from current cycles

All issue ACs met. No findings at any severity remain unresolved. Implementation is coherent and merge-ready.
