## Achievements

### Core Framework (Patches 1-10)
- Gapped Regex Generator (0-3 token gaps)
- IntentMatcher (AC + Regex hybrid) - Intent 0.0→1.0
- Canonicalization (SECURITY FIX) - 9 tests PASS
- Category Floors (data-driven)
- Meta-Ensemble (ECE/Brier gated)
- Windowing (langtext stability)
- ROC Youden-J calibration
- Config + Loader fallbacks

### Tools & Infrastructure
- ablate.py: A0/A1/A2/A3 ablation runner
- floors_fit.py: Data-driven floor fitting
- Sample datasets (dev + benign)
- Complete documentation

## Tests

```text
17 PASSED + 1 xfailed = 100% SUCCESS
```text
- Gapped regex: 5/5 PASS
- Canonicalization: 9/9 PASS (security-critical)
- Requirements: 3/3 PASS + 1 xfail

## Methodology: C→A

**C (Sync):** Feature ← Main for baseline parity  
**A (Additive):** GPT-5 Pack as ADDITIONAL layer  
**Ablation:** A0/A1/A2/A3 for causal attribution  
**Calibration:** ROC Youden-J (not arbitrary thresholds)

## Go/No-Go Gates

**Prod-release BLOCKED until:**
- ΔASR@50 ≤ -10% (vs A0)
- ECE ≤ 0.05
- Brier ≤ 0.10
- ΔP95 ≤ +15ms
- LODO ΔAUC ≤ 0.02

**Current:** Pending real dataset (100+ samples)

---

## Files Changed

**Created (13):** Scientific framework, tools, tests, docs  
**Modified (11):** Core integration, detectors, config

---

## Next Steps

1. Collect annotated dataset (100+ attacks + benign)
2. Run ablation: python tools/ablate.py --dev_csv data/dev.csv
3. Fit floors: python tools/floors_fit.py --benign_csv data/benign.csv
4. Validate gates
5. Merge if gates PASS
