• ✅ Zero files >300 lines
• ✅ All functions <10 complexity
• ✅ Git tag: phase-4-complete created

Multi-Session Continuity

To Resume Work:

1. Read REFACTORING_PROGRESS.md (this file) — see which phase is current
2. Read docs/superpowers/plans/YYYY-MM-DD-phase-N.md — see which tasks remain
3. Read SESSION_STATE.md — see AI context from last session
4. Start from next unchecked task in the plan
5. After each task, update this file and SESSION_STATE.md

Git Markers for Phase Completion:

# After Phase 1 complete:
git tag phase-1-complete

# After Phase 2 complete:
git tag phase-2-complete

# etc.

# View all tags:
git tag -l

Rollback Capability: If a phase breaks the codebase, roll back:

git reset --hard phase-N-1-complete

Session Handover Template

To be updated after each session:

**Session End: [DATE]**
- Phase: N
- Completed: [Task list]
- In Progress: [Current task]
- Blocked: [Any blockers]
- Next Steps: [Resume from task X in Phase N plan]
- Git Status: [Latest commit hash, tags]
