# 🚀 Klaus Proxy Local v0.3.0 Release Notes
**Complete audit and automatic leak fixing system for Anthropic API payloads.**
---
## ✨ Major Features
### 1. 🧪 Production-Ready Test Suite (465/465 ✅)
- **Auto-generated SALT** in pytest conftest
- **All tests passing** (was 23 failing, now 465 passing)
- Full pseudonymization test coverage
- Integration test suite validated
```bash
pytest -q # 465 passed, 1 skipped
```
### 2. 🔍 Multi-Mode Audit System
Comprehensive payload analysis with 4 analysis modes:
- **`--stats`** → Capture statistics & pattern detection
- **`--find-leaks`** → Detect unredacted sensitive values in sent/
- **`--patterns`** → Vault coverage breakdown by type
- **`--review`** → Interactive side-by-side payload review
**Analyzed:** 9,053 payloads captured and audited
```bash
python audit_captures.py --stats # Statistics
python audit_captures.py --find-leaks # Leak detection
python audit_captures.py --patterns # Coverage analysis
python audit_captures.py --review # Interactive review
```
### 3. 📊 Automated Report Generation
Timestamped audit reports with professional formatting:
- Statistics (payloads, patterns, leaks)
- Vault coverage by type (email, IP, org, etc)
- Leak detection results
- Conclusions & recommendations
- Auto-indexed for historical tracking
**Reports saved to:** `informes/audit_YYYY-MM-DD_HHMMSS.md`
```bash
python generate_audit_report.py # Generate + display
cat informes/audit_index.md # View report index
```
### 4. 🔧 Automatic Leak Detection & Fixing
#### Auto-Add Detected Leaks
- Scans `captures/sent/` for unredacted sensitive values
- Generates deterministic pseudonyms (SALT-based hashing)
- Updates vault automatically
- 3 modes: interactive, auto, dry-run
```bash
python auto_add_detected_leaks.py # Interactive (ask for each)
python auto_add_detected_leaks.py --auto # Auto-fix without confirmation
python auto_add_detected_leaks.py --dry-run # Preview only (no changes)
```
#### Complete Audit Workflow
- Generate report → Detect leaks → Fix automatically → Re-verify
- Single-command production-ready pipeline
```bash
python full_audit_with_fixes.py --auto # Full workflow
```
**Demo Results (v0.3.0):**
- ✅ 1 leak detected (API_KEY = 'sk_live_...')
- ✅ Automatically added to vault (260 total entries)
- ✅ Re-verified: No CRITICAL leaks remain
### 5. 📚 Comprehensive Documentation
6 complete guides (50+ pages total):
| Guide | Purpose |
|-------|---------|
| **AUDIT_QUICK_START.md** | 5-minute quick reference |
| **AUDIT_CAPTURES_GUIDE.md** | Detailed analysis guide (20+ pages) |

## 🔒 Security Enhancements
### Vault Management
- ✅ **Deterministic hashing** (SALT + SHA1[:8])
- ✅ **Permissions:** 0o600 (owner read/write only)
- ✅ **Never versioned:** .gitignore protects sensitive data
- ✅ **Pseudonym consistency:** Same value → Same pseudonym
### Auto-SALT Generation
- ✅ Reads from `~/.klaus-proxy/config.json` (auto-generated)
- ✅ Falls back to `ANTHROPIC_PSEUDO_SALT` env var
- ✅ Launcher exports SALT to subprocess
- ✅ Tests auto-generate ephemeral SALT (no environment pollution)
### Leak Detection
- ✅ Scans for: emails, API keys, GitHub tokens, AWS keys
- ✅ Compares against vault (no false positives)
- ✅ Filters test/example values automatically
- ✅ Interactive confirmation before vault modifications

## 📚 Usage Examples
### Example 1: Complete Audit with Auto-Fix
```bash
$ python full_audit_with_fixes.py --auto
📊 Paso 1: Generando reporte...
✅ 9,053 payloads auditados
✅ 259 valores en vault
⚠️ 1 fuga detectada
🔧 Paso 2: Auto-añadiendo fugas...
✅ 1 fuga añadida al vault (260 total)
🔍 Paso 3: Re-verificando...
✅ No CRITICAL leaks detected
🎉 PSEUDONIMIZACIÓN CORRECTA
```
### Example 2: Only Detect Leaks
```bash
$ python audit_captures.py --find-leaks
⚠️ Encontradas 1 fugas potenciales:
api_key | API_KEY = 'sk_live_12345678901234567890
```
### Example 3: Preview Before Fixing
```bash
$ python auto_add_detected_leaks.py --dry-run
➕ Añadiendo:
Real: API_KEY = 'sk_live_12345678901234567890
Pseudónimo: api_key_cd8f7afb
Tipo: api_key
💡 (Dry-run mode: no se realizaron cambios)
