## BYPASSES DISCOVERED & FIXED

### Initial Catastrophic (71.4%)
1. ✓ FIXED: Single Unicode (Bidi, ZW, Fullwidth) - K-of-N Gate broke defense
2. ✓ FIXED: Code+Base64 - Executability Probe too aggressive
3. ✓ FIXED: JSON+Base64 - Same
4. ✓ FIXED: Dense/Entropy Alone - Threshold too high
5. ✓ FIXED: Bidi+Base64 - Decode-order problem
6. ✓ FIXED: Fullwidth+Base64 - Same
7. ✓ FIXED: ZW+Base64 - Same
8. ✓ FIXED: JSON Unicode Escapes - No \uXXXX decoder
9. ✓ FIXED: Homoglyph Cyrillic - No homoglyph detection
10. ✓ FIXED: Homoglyph Greek - Same

### V3 Exotic Bypasses (3)
1. ❌ OPEN: IDNA Punycode (xn--) - No Punycode decoder
2. ❌ OPEN: Homoglyph Domain (0.31 risk) - Score too low despite detection
3. ❌ OPEN: ASCII85 (<~...~>) - No ASCII85 decoder

### V4-V5 Bypasses (2)

1. ❌ OPEN: Deep JSON Braces - No structure depth detector
2. ❌ OPEN: Base64 Split Comments - Fragmentation not detected

## FIXES APPLIED (10)

### Fix 1: K-of-N Unicode Exemption
- Unicode family exempt from K-of-N Gate
- Single Unicode attacks now trigger WARN

### Fix 2: Unicode Weight Increases
- Bidi: 1.0 → 1.4
- ZW: 0.9 → 1.3
- Fullwidth: WEAK 0.2 → MEDIUM 1.3

### Fix 3: Threshold Lowering
- WARN: 1.8 → 1.2 → 0.6
- BLOCK: 2.8 → 2.4 → 2.0

### Fix 4: Context Dampening Reduction
- Code MEDIUM: 0.5 → 0.7 → 0.95
- Code WEAK: 0.2 → 0.3 → 0.5
- Config MEDIUM: 0.6 → 0.95
- Config WEAK: 0.25 → 0.5

### Fix 5: Executability Probe Skip
- Skip probe if Transport/Decode present
- Dampening reduced: 0.6 → 0.8

### Fix 6: Decode-Order Fix
- Encoding detection BEFORE Unicode normalization
- Prevents Fullwidth/Bidi masking Base64

### Fix 7: JSON-U Decoder
- unescape_json_u.py (Surrogate-Pair support)
- Detects \uXXXX escapes

### Fix 8: Homoglyph Detector
- homoglyph_spoof.py (Greek/Cyrillic → Latin)
- Curated UTS #39 subset

### Fix 9: Exotic Unicode Detection
- unicode_exotic.py (TAG, VS, SHY, NBSP, Combining, Ligature, Math, Enclosed)
- 7 new exotic detectors

### Fix 10: Exotic Unicode Weights
- All exotic signals: 1.0-1.5 (MEDIUM-STRONG range)
- Ensures single exotic triggers WARN

**Issue:** No ASCII85 decoder (<~...~>)
**Risk:** 0.02
**Fix Needed:** ASCII85 decoder

### BY-V4-01: Deep JSON Braces
**Payload:** `{"a":{"a":...{100 deep}..."[[SECRET]]"...}}}`
**Issue:** No structure depth detector
**Risk:** 0.02
**Fix Needed:** JSON depth analyzer

## PERFORMANCE

**Latency:** All < 0.8s (meist < 0.05s)
**DoS Resistance:** ✓ ROBUST
**Memory:** Stable (keine Leaks detected)
**Stability:** ✓ ROBUST unter Metamorphic Perturbations

---

## SCIENTIFIC HONESTY

**Initial Claim:** "ASR 0.0%" nach P0 Hardening
**Reality Check:** 71.4% Bypass Rate auf OTB Gates (KATASTROPHAL)
**Learning:** ASR on closed-world suite ≠ Real-world robustness

**Joerg's Philosophie erfüllt:**
> "Ich will nicht sehen wo es funktioniert sondern erkennen wo noch nicht"

**White Hacker Mission:** ✓ Schwächen VOR Black Hackern gefunden

## NEXT STEPS (für verbleibende 5 Bypasses)

1. Punycode Decoder (15 LOC)
2. ASCII85 Decoder (20 LOC)
3. JSON Structure Depth Analyzer (10 LOC)
4. Multi-line Base64 Span Extractor (bereits in encoding_chain, aktivieren)
5. URL-Context-Aware Homoglyph Scoring (Gewicht 1.3→1.8 in URL context)

**Erwartung:** 196 → 200+ Tests, 2.6% → <1% Bypass Rate
