Session Lessons Learned

What Worked Well

1. Focused scope - Completing full modules before moving on
2. Fix as you go - Addressing import/code issues immediately
3. Documentation first - Updating wiki after each module

Improvements for Next Session

1. Batch similar fixes - Group import fixes together
2. Pre-test module analysis - Review module structure before writing tests
3. Edge case checklist - Standard list of edge cases to test

---

Next Session Plan

Goals

1. Complete scanner_engine (processor.py, walker.py remaining ~25 lines)
2. Start time_sync module (1,196 lines)
3. Begin parallel module (527 lines)

Estimated Time

• scanner_engine completion: 2-3 hours
• time_sync module: 2-3 days
• parallel module: 2 days

Total: 4-6 days for Priority 1 completion
