## §2.0.0 Contract Integrity

| Check | Result | Notes |
|---|---|---|
| Status truth preserved | no | α claims all ACs complete with evidence, but implementation not committed to branch |
| Canonical sources/paths verified | no | Cannot verify - artifacts not in git diff |
| Scope/non-goals consistent | yes | Issue scope clear, non-goals explicit |
| Constraint strata consistent | yes | AC constraints consistent with issue requirements |
| Exceptions field-specific/reasoned | n/a | No exceptions claimed |
| Path resolution base explicit | yes | Base SHA 7e578694 explicit in self-coherence |
| Proof shape adequate | no | Claims backed only by prose description, not verifiable git diff |
| Cross-surface projections updated | no | Cannot verify without committed diff |
| No witness theater / false closure | no | False closure - claims evidence exists but not committed |
| PR body matches branch files | n/a | No PR in triadic protocol |

## §2.0 Issue Contract

| # | AC | In diff? | Status | Notes |
|---|----|----------|--------|-------|
| AC1 | ship/SKILL.md section | no | not committed | Modified file exists in working dir but not committed |

### Named Doc Updates

| Doc / File | In diff? | Status | Notes |
|------------|----------|--------|-------|
| ship/SKILL.md | no | not committed | Required new section exists but not committed |
| release/SKILL.md | no | not committed | Required reference exists but not committed |
| gamma/SKILL.md | no | not committed | Required reference exists but not committed |

### CDD Artifact Contract

| Artifact | Required? | Present? | Notes |
|----------|-----------|----------|-------|
| self-coherence.md | yes | yes | Present and signals ready for β |
| alpha-closeout.md | post-merge | n/a | Not yet required |

### Active Skill Consistency

| Skill | Required by | Loaded? | Applied? | Notes |
|-------|-------------|---------|----------|-------|
| skill/SKILL.md | Tier 3 | claimed | unknown | Cannot verify application without committed work |
| eng/tool | Tier 2 | claimed | unknown | Cannot verify hook script implementation |
| eng/document | Tier 2 | claimed | unknown | Cannot verify doc updates |
| eng/test | Tier 2 | claimed | unknown | Cannot verify test fixture |

## Findings

| # | Finding | Evidence | Severity | Type |
|---|---------|----------|----------|------|
| F1 | Implementation not committed to branch | `git diff main..cycle/273 --stat` shows only self-coherence.md; working directory has untracked/modified files for all claimed deliverables | D | contract |
| F2 | False review-readiness signal | self-coherence.md signals "Ready for β" but implementation artifacts are not in git history for review | D | contract |
| F3 | Evidence claims not backed by diff | Each AC claims "Evidence: Created/Added/Modified X" but X is not in the committed diff | D | honest-claim |

## Regressions Required (D-level only)

### F1 - Implementation not committed
**Positive case:** After α commits implementation files, `git diff main..cycle/273` should show all artifacts listed in self-coherence.md §ACs  
**Negative case:** Current state where `git diff main..cycle/273` shows only self-coherence.md

### F2 - False review-readiness signal  
**Positive case:** Review-readiness signal should only be written after implementation artifacts are committed and verifiable via git diff  
**Negative case:** Current state where readiness is signaled with no committed implementation

### F3 - Evidence claims not backed by diff
**Positive case:** Each "Evidence: Created/Added/Modified X" claim should correspond to a verifiable change in `git diff main..cycle/273`  
**Negative case:** Current state where evidence claims exist only as prose without corresponding git changes

## Notes

The implementation files exist in the working directory and appear to address the ACs based on quick inspection, but fundamental CDD protocol violation prevents proper review. α must commit all implementation work to the cycle branch before β can perform code review and verdict.

Cannot proceed to implementation review phase (§2.1) until contract integrity violations are resolved.

## §2.1 Implementation Review

### Code Quality Assessment

**Hook Script (`hooks/pre-push`):**
- ✅ Implements upstream-added file detection (`--diff-filter=A`)
- ✅ Implements upstream-modified content detection (`--diff-filter=M`) 
- ✅ Provides ALLOW_CONTENT_LOSS bypass mechanism
- ✅ Clear error messages with remediation steps
- ✅ Proper error handling and exit codes
- ✅ Only triggers on main/master pushes, fast-forward detection

**Installer Script (`scripts/install-hooks.sh`):**
- ✅ Prerequisites checking (git repo, hooks directory)
- ✅ Proper git config setup for hooks path
- ✅ Error handling and user feedback

**Test Fixture:**
- ✅ Three test cases per AC6: clean rebase passes, LOST-NEW fails, LOST-MOD addressed
- ✅ Throwaway repo setup/cleanup
- ✅ Exit code and output verification

**Skill Documentation Updates:**
- ✅ ship/SKILL.md comprehensive section matches γ #268 evidence
- ✅ Cross-references added to release/ and gamma/ skills at specified boundaries
- ✅ Installation patterns documented with working commands

### Mechanical Verification

**File permissions:** `hooks/pre-push` and test fixture executable ✅  
**Path consistency:** All paths match canonical AC specifications ✅  
**Cross-reference accuracy:** CDD skill references point to correct section ✅

## CI Status

**Status:** Provisional (red) — infrastructure issue  
**Assessment:** CI failures appear to be workflow configuration issue (Go 1.24 version likely not available), not cycle implementation defect  
**Impact:** Per rule 3.10, CI must be green for APPROVED verdict

## Findings

| # | Finding | Evidence | Severity | Type |
|---|---------|----------|----------|------|
| F4 | CI infrastructure blocking approval | `gh run list --branch cycle/273` shows workflow failures; Go 1.24 in build.yml likely unavailable on GitHub Actions | B | ci-status |

## Regression Required (B-level)

### F4 - CI infrastructure issue
**Positive case:** CI should pass or use available Go version (1.21-1.23 range typically available)  
**Negative case:** Current state where workflow fails due to Go 1.24 specification

## Implementation Assessment Summary

The cycle implementation is **technically complete and correct** for all ACs. The rebase-collision integrity guard addresses the exact failure class from γ #268 with appropriate detection logic, bypass mechanisms, installation patterns, and comprehensive testing. Cross-references are properly placed. Regression baseline verified.

The CI failure is a **repository-wide infrastructure issue** (Go version configuration) unrelated to the cycle's git hook implementation, but rule 3.10 binding requirement prevents APPROVED verdict until resolved.

# Round 3

**Verdict:** APPROVED

**Round:** 3  
**Fixed this round:** 3bacacad — CI YAML syntax fix, CI now green  
**Branch CI state:** GREEN (completed/success)  
**Base SHA:** 7e5786944ffe60e16e856fa2cf0ecf9b564613b6 (origin/main)  
**Review SHA:** 3bacacad (merge main: fix CI YAML syntax)  
**Merge instruction:** Merge cycle/273 → main with `--no-ff`, message "Closes #273"

## R2 Finding Resolution Verification

| # | R2 Finding | Status | Evidence |
|---|------------|--------|----------|
| F4 | CI infrastructure blocking approval | ✅ FIXED | CI workflow now passes with success status on commit 3bacacad |

## Final Assessment

All acceptance criteria remain satisfied from R2 review. CI infrastructure issue resolved by δ's build.yml fix merged into cycle/273. Implementation integrity preserved across CI fix merge.

**Ready for integration.**
