🔄 Emergency Rollback Guide

⚡ QUICK ROLLBACK (30 seconds)

If anything fails after deployment, run these commands immediately:

# Navigate to project
cd /home/amit/projects/quantum_ai_v3

# Emergency: Revert ALL changes to last working state
git reset --hard 1cfdac2  # Last clean commit before optimizations
git clean -fd            # Remove any untracked files

# Verify clean state
git status              # Should show "working tree clean"

🎯 SELECTIVE ROLLBACK

If Railway deployment fails:

# Revert just deployment configs
git checkout HEAD~1 -- railway.json
git checkout HEAD~1 -- requirements.txt
git checkout HEAD~1 -- netcop_hub/settings.py

If database issues:

# Rollback migrations
python manage.py migrate agents 0007
python manage.py migrate wallet 0002

If import errors:

# Remove new security files
rm -f core/middleware.py
rm -f core/validators.py  
rm -f core/cache_utils.py
git checkout HEAD~1 -- netcop_hub/settings.py

📍 COMMIT REFERENCES

• Current (optimized): 87ec7cc - Security & Performance Optimization
• Last safe state: 1cfdac2 - Remove Demo Business Calculator agent
• Clean baseline: 2583d83 - Add Demo Business Calculator agent

🚨 EMERGENCY CONTACTS

If you need to rollback:

1. Stop Railway deployment (if in progress)
2. Run quick rollback commands above
3. Verify application works locally: python manage.py runserver
4. Redeploy clean state to Railway
5. Test deployment works

🔍 TROUBLESHOOTING

Common failure patterns:

Error	Quick Fix
ModuleNotFoundError: bleach	git checkout HEAD~1 -- requirements.txt
NameError: logging	git checkout HEAD~1 -- netcop_hub/settings.py
Migration failure	python manage.py migrate --fake
Railway hanging	git checkout HEAD~1 -- railway.json
Admin command error	git checkout HEAD~1 -- core/management/commands/

✅ RECOVERY VERIFICATION

# Test Django startup
python manage.py check

# Test migrations
