feat: benchmark suite + scoring calibration - iteration 4/5
Implements comprehensive benchmarking infrastructure and tunes scoring weights based on empirical accuracy measurements. New Components: - tests/benchmark/test_data_generator.py: Synthetic signal generator for 12 protocols - scripts/benchmark.py: Full benchmarking suite with accuracy metrics - TEST_RESULTS_SUMMARY.md: Detailed benchmark results and per-protocol analysis Benchmark Results: - Total Tests: 12 synthetic signals across 10 protocols - Top-1 Accuracy: 33.3% (4/12 correct) - Top-3 Accuracy: 33.3% - Confidence Distribution: 66.7% high (>80%), 25% medium (50-80%), 8.3% low (<50%) - Avg Processing Time: 144.6ms per signal Scoring Weight Tuning: BEFORE: Timing(30%) + Frequency(25%) + BitCount(20%) + Preamble(15%) + Stats(10%) AFTER: Timing(35%) + Preamble(25%) + BitCount(20%) + Frequency(15%) + Stats(5%) Rationale: - Increased Preamble weight (15% → 25%): Highly discriminative for protocol identification - Increased Timing weight (30% → 35%): Core identification feature - Decreased Frequency weight (25% → 15%): Many protocols share same ISM band - Decreased Stats weight (10% → 5%): Less discriminative in practice Confidence Thresholds: - High: >80% (reliable identification) - Medium: 50-80% (possible match, needs verification) - Low: <50% (uncertain, likely incorrect) Protocol Performance: ✓ Excellent (100%): LaCrosse TX141-BV2, Oregon Scientific v2.1, Schrader TPMS ✗ Needs Improvement (0%): Acurite 609TXC, Princeton, PT2262, Nexus, Toyota TPMS Key Findings: - Preamble detection critical for discrimination (alternating patterns work well) - Timing analysis robust to 15% noise - 315 MHz protocols underrepresented in database - Generic protocols difficult to distinguish without more specific signatures Next Steps (Future Iterations): - Expand 315 MHz protocol coverage - Add protocol-specific heuristics for Princeton, PT2262 - Improve bit pattern matching for similar timing protocols 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
