## Stage 1: Spec Compliance

### Success Criteria Check

#### Good Enough Criteria
- [PASS] Criterion 1: <how it was met>
- [FAIL] Criterion 2: <why not met, what's missing>

#### Exceptional Criteria
- [PARTIAL] Criterion 1: <what's done, what's remaining>

### Boundary Check
- [RESPECTED] Boundary 1: <confirmation>
- [VIOLATED] Boundary 2: <what violated it>

## Stage 2: Code Quality

### Stub Detection
- Files scanned: N
- Issues found: N
- [Details of each issue]

### Quality Review
- Architecture: [PASS/WARN/FAIL]
- Error Handling: [PASS/WARN/FAIL]
- Security: [PASS/WARN/FAIL]
- Performance: [PASS/WARN/FAIL]
- Readability: [PASS/WARN/FAIL]
- Test Coverage: [PASS/WARN/FAIL]

### Blocking Issues
[List any issues that must be fixed before merge]

### Recommendations
[Non-blocking suggestions for improvement]

## Staged Review — Complete

### Stage 1: Spec Compliance
- Success Criteria: N/N passed
- Boundaries: N/N respected
- Verdict: [PASS/FAIL]

### Stage 2: Code Quality
- Stub Detection: N issues
- Quality Score: [HIGH/MEDIUM/LOW]
- Blocking Issues: N
- Verdict: [PASS/FAIL]

### Overall Verdict: [PASS/FAIL]

[If FAIL: list specific items that must be addressed]
[If PASS: ready for merge/ship]

Staged Review = Spec Compliance (Stage 1) + Code Quality (Stage 2)
Stage 1 gates Stage 2. Both must pass for overall PASS.
