## Coverage Analysis

### Acceptance Criteria Coverage

**AC1.3: Speedup ratio ≥50x documented with statistical confidence**
- ✅ COVERED: PERFORMANCE.md documents 66,054x speedup
- ✅ VERIFIED: Conservative estimate 64,661x exceeds 50x target
- ✅ TESTED: 18 tests in test_cpython_comparison.rs validate all aspects

**Comparison uses identical Python code between PyRust and CPython**
- ✅ COVERED: Both benchmarks use "2 + 3"
- ✅ TESTED: test_benchmarks_use_identical_code
- ✅ TESTED: test_identical_python_code

**Results include statistical confidence intervals**
- ✅ COVERED: PERFORMANCE.md shows 95% CI for all measurements
- ✅ TESTED: test_confidence_intervals
- ✅ TESTED: test_benchmark_json_schema_valid

**Both warm execution and total time comparisons implemented**
- ✅ COVERED: Benchmarks for both scenarios exist
- ✅ TESTED: test_warm_and_total_time_comparison
- ✅ TESTED: test_warm_vs_cold_benchmarks_both_exist
- ✅ TESTED: test_warm_execution_benchmark_exists

**Benchmark verifies python3 is available on system**
- ✅ COVERED: cpython_baseline.rs checks python3 before running
- ✅ TESTED: test_benchmark_checks_python3
- ✅ TESTED: test_script_checks_python3
- ✅ TESTED: test_handles_missing_python3

## Edge Cases Tested

1. ✅ Empty program benchmarking (test_edge_case_empty_program_benchmark)
2. ✅ All operators benchmarking (test_edge_case_all_operators_benchmark)
3. ✅ Missing python3 handling (test_handles_missing_python3)
4. ✅ Missing jq handling (test_handles_missing_jq)
5. ✅ Missing benchmark data handling (test_handles_missing_data)
6. ✅ Script error handling and output format validation

## Statistical Validation

**AC1.5: Variance < 10% coefficient of variation**
- ✅ PyRust CV: 1.29% (well below 10%)
- ✅ CPython CV: 1.74% (well below 10%)
- ✅ TESTED: test_benchmark_stability_meets_ac15
- ✅ TESTED: test_variance_validation

**AC1.2: Cold start < 100μs**
- ✅ Actual: 293.34 ns (0.29 μs)
- ✅ Target exceeded by 340x
- ✅ TESTED: test_cold_start_performance_meets_ac12

## Conclusion

All tests pass. The coder's implementation of PERFORMANCE.md successfully documents:
1. ✅ Speedup ratio ≥50x (actual: 66,054x)
2. ✅ Statistical confidence intervals (95% CI)
3. ✅ Identical Python code usage
4. ✅ Both warm and cold execution comparisons
5. ✅ Python3 availability verification
6. ✅ Comprehensive edge case handling

No failures, no missing coverage, no additional tests needed.
