🔄 ROLLBACK PROCEDURES

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

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

Procedure:

# 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:

# 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:

# 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
