## 🔄 ROLLBACK PROCEDURES

### Level 1: Individual Agent Rollback (Per-Agent, <5 minutes)

**When to Use**: Single agent fails, rest of track succeeds

**Procedure**:
```bash
# Identify failing agent
git status

# Stash changes
git stash push -m "AGENT-FIX-XX rollback"

# Verify previous state
cargo test -p <affected-package>

# Document failure
echo "AGENT-FIX-XX failed: <reason>" >> ROLLBACK_LOG.md
```

**Impact**: Minimal (other agents in track continue)

---

### Level 2: Track Rollback (Per-Track, <15 minutes)

**When to Use**: Entire track fails or introduces regressions

**Procedure**:
```bash
# Identify failing track
git log --oneline -n 10

# Rollback all track commits
git reset --hard <pre-track-commit-hash>

# Verify workspace integrity
cargo build --workspace
cargo test --workspace

# Document failure
echo "TRACK-X failed: <reason>" >> ROLLBACK_LOG.md
```

**Impact**: Medium (may block dependent tracks)

---

### Level 3: Full Roadmap Rollback (<30 minutes)

**When to Use**: Critical bug introduced, production deployment blocked

**Procedure**:
```bash
# Nuclear option: rollback to clean state
git reset --hard HEAD~25  # Rollback all 25 agents

# OR use backup branch
git checkout -b roadmap-backup
git branch -D main
git checkout main
git pull origin main

# Verify clean state
cargo build --workspace --release
cargo test --workspace

# Document failure
echo "FULL ROADMAP ROLLBACK: <reason>" >> ROLLBACK_LOG.md

# Alert team
echo "🚨 Full roadmap rollback executed" | mail -s "CRITICAL: Rollback" team@foxhunt.com
```

**Impact**: High (all roadmap progress lost)

## 📊 RISK ASSESSMENT

### Risk Matrix

| Risk Level | Count | Mitigation |
|------------|-------|------------|
| 🔴 **High** | 2 agents | AGENT-QAT-03, AGENT-QAT-06 - Extensive testing, rollback ready |
| 🟡 **Medium** | 7 agents | AGENT-FIX-01, 02, QAT-02, 04, 05, MANUAL-01, 06 - Code review + tests |
| 🟢 **Low** | 16 agents | Most auto-fixes + validation - Safe automated changes |
| **Total** | **25 agents** | Comprehensive rollback procedures at 3 levels |

### Risk Mitigation Strategies

#### High-Risk Agents (2)
1. **AGENT-QAT-03** (TFT Quantized Attention)
   - **Risk**: Shape mismatch may affect inference accuracy
   - **Mitigation**:
     - Extensive unit tests (7 attention tests)
     - Compare output with FP32 baseline
     - Validate with real market data inference
   - **Rollback**: Level 2 (Track 2 rollback)

2. **AGENT-QAT-06** (Gradient Checkpointing)
   - **Risk**: Memory optimization may introduce training instability
   - **Mitigation**:
     - DEFER TO POST-100% SPRINT (not required for certification)
     - Extensive training validation if implemented
   - **Rollback**: Level 1 (agent-specific)

#### Medium-Risk Agents (7)
- **AGENT-FIX-01, 02, 03**: Common crate error handling changes
  - **Risk**: May affect error reporting semantics
  - **Mitigation**: Comprehensive test suite (110 common tests)

- **AGENT-QAT-02**: Observer state serialization
  - **Risk**: Checkpoint format changes may break existing models
  - **Mitigation**: Backward compatibility check, version tagging

- **AGENT-MANUAL-01**: needless_borrows fixes
  - **Risk**: May introduce lifetime violations
  - **Mitigation**: Only fix 10 safest cases, defer complex ones

#### Low-Risk Agents (16)
- All auto-fix agents (CLIPPY-01 through 05)
- Simple manual fixes (MANUAL-02 through 05)
- Validation agents (VAL-01, VAL-02)
- **Risk**: Minimal (automated or trivial changes)
- **Mitigation**: Standard test suite validation
