## Phase 3: E2E Tests (Playwright)
**Target:** 5+ critical workflows automated
**E2E Workflows:**
- [ ] Login workflow (LDAP + local)
- [ ] Scan item → match inventory
- [ ] Create new item (AI extraction)
- [ ] Admin settings change
- [ ] Offline sync (simulate network loss)
**Test File:**
- [ ] `frontend/e2e/critical-workflows.spec.ts`
**Completion Criteria:**
- ✅ 5+ workflows automated
-`npx playwright test` — all passing
- ✅ Runtime <30 min
- ✅ Git tag: `phase-3-complete` created
- ✅ SESSION_STATE.md updated with Phase 3 status

## Phase 4: Backend Refactoring
**Target:** Split 3 routers into smaller, focused modules
**Routers to Refactor:**
1. `backend/routers/users.py` (443 lines) → Split into:
- `backend/routers/users.py` (endpoints, <150 lines)
- `backend/services/user_service.py` (CRUD logic)
- `backend/validators/user_validator.py` (input validation)
2. `backend/routers/operations.py` (298 lines) → Split into:
- `backend/routers/operations.py` (endpoints, <150 lines)
- `backend/services/operation_service.py` (business logic)
3. `backend/routers/items.py` (240 lines) → Split into:
- `backend/routers/items.py` (endpoints, <150 lines)
- `backend/services/item_service.py` (business logic)
**Completion Criteria:**
- ✅ All 3 routers split into service modules
-`pytest backend/tests/ --cov=backend` — 85%+ coverage, all tests PASS
- ✅ Zero files >300 lines
- ✅ All functions <10 complexity
- ✅ Git tag: `phase-4-complete` created
- ✅ SESSION_STATE.md updated with Phase 4 status
**Note:** No behavior changes. Tests validate before/after refactor.

## Phase 6: Page Refactoring
**Target:** Extract page logic into hooks, reduce file sizes
**Pages to Refactor:**
1. `frontend/app/page.tsx` (979 lines) → Split into:

## 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:**
```bash
# 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:
```bash
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]
```
