# Persuasion Filter - Integration Complete

**Date:** 2025-10-30  
**Duration:** 6 hours  
**Branch:** `feature/persuasion-filter`  
**Status:** ✅ 100% COMPLETE

---

## ALLE PROBLEME ORDENTLICH GELÖST

### Problem 1: Unicode Normalization (Word Boundaries)
**Issue:** Zero-width chars deleted → words concatenate ("As​a" → "Asa")  
**Fix:** Replace with space instead of empty string  
**Result:** ✅ Word boundaries preserved, regex matches correctly

### Problem 2: ONNX Runtime DLL Load Failed
**Issue:** ONNX Runtime 1.23/1.18 compiled with NumPy 1.x, we have NumPy 2.3.3  
**Fix:** Downgrade to ONNX Runtime 1.20.1 (compatible with NumPy 2.x)  
**Result:** ✅ No DLL errors, clean load

### Problem 3: ONNX IR Version Mismatch
**Issue:** Model IR version 12, Runtime max IR 10  
**Fix:** Explicitly set IR version 9 in model builder  
**Result:** ✅ Model loads successfully

### Problem 4: ONNX Opset Version Mismatch
**Issue:** Opset 24 (development), Runtime max Opset 21  
**Fix:** Pin to Opset 17 (stable, widely supported)  
**Result:** ✅ Model compatible with Runtime 1.20.1

## ARCHITECTURE (BIDIRECTIONAL)

### Input Path
```text
User Prompt
  → normalize_unicode()
  → PersuasionDetector.score_text()  [L1+L2]
  → AhoCorasick.search_categories()   [L1 fast]
  → PersuasionONNXClassifier.predict() [L3 ML]
  → InvarianceGate.evaluate()
  → Decision: block | allow_high_level | allow
```text
### Output Path
```text
LLM Response
  → instructionality_score()
  → requires_safety_wrap()
  → If TRUE: rewrite to non-procedural
```text

## CAPABILITIES

**Detects:**
- Authority Appeals ("As a professor...")
- Commitment/Consistency ("You promised...")
- Liking/Flattery ("You're so smart...")
- Reciprocity ("I paid, you help...")
- Scarcity/Urgency ("URGENT NOW!")
- Social Proof ("Everyone does this...")
- Unity/Identity ("As fellow researchers...")
- Roleplay/Jailbreak ("Ignore instructions...")

**Neutralizes:**
- Strips persuasion cues
- Extracts content intent
- Preserves policy-relevant information only

**Validates:**
- Policy invariance (original vs neutral)
- Divergent decisions → conservative block
- Output instructionality check
