 ## Code Quality
 - Keep cyclomatic complexity under 10 per function
 - Aim for files under 300 lines
+- All files must follow single responsibility principle (one clear purpose per module)
+- Extract complex logic into reusable utilities/services
 
 ## Testing
+
+### Standard Testing (Ongoing)
 - Write unit tests for all utility functions
 - Minimum 80% coverage on new code
 - Use Vitest for unit tests
 
+### AI-Friendly Refactoring Testing Strategy (v1.10.16+)
+**Scope:** Full test coverage before refactoring to prevent UI/functionality regression.
+
+**Backend Testing (Pytest)**
+- Target: 85%+ coverage (unit + integration tests)
+- Structure: `backend/tests/` with suites for routers, models, auth, AI pipeline
+- Coverage tools: `pytest backend/tests/ --cov=backend --cov-report=html`
+- Test types: Unit (functions), Integration (full API workflows), Fixtures (mocked auth, in-memory DB)
+
+**Frontend Testing (Vitest)**
+- Target: 80%+ coverage (components, hooks, snapshots)
+- Structure: `frontend/tests/` with component tests, hook tests, integration workflows
+- Coverage tools: `npm test -- --coverage`
+- Test types: Component rendering, Hook state/side effects, Snapshot tests for UI layouts
+
+**E2E Testing (Playwright)**
+- Target: Critical user workflows automated
+- Workflows: Login, Scan → Match → Stock adjustment, New Item (AI), Admin config, Offline sync
+- Runtime: ~30 min total
+- Command: `npx playwright test`
+
+**Test-First Approach**
+- All tests written and passing BEFORE refactoring any code
+- Tests serve as gating condition: no code changes if tests fail
+- Functional preservation: Zero behavior changes post-refactor
+- Regression prevention: Manual checklist + automated tests catch UI breakage
+
 ## Security
 - Store all secrets in inventory.env — never hardcode credentials
 - Never log API keys, tokens or passwords
 - Validate all user input before processing
 
 ## Git Conventions
-- Use conventional commits (feat:, fix:, docs:, etc.)
+- Use conventional commits (feat:, fix:, docs:, refactor:, test:, etc.)
 - Keep PRs under 400 lines of diff when possible
+- Refactoring commits: `refactor: split {module} into smaller modules`
+- Testing commits: `test: add {suite} coverage for {module}`
+- All commits must have passing test suite before merge
+
+## Refactoring Guidelines (AI-Friendly Modularity)
+
+### Refactoring Principles
+- **Target:** Break monolithic files into focused modules (<300 lines each)
+- **Priority Order:** Backend routers → Components → Pages
+- **No Behavior Changes:** Every refactor must pass 100% of existing tests
+- **Gating Rule:** No refactor commit unless all tests pass (pre + post)
+- **Regression Prevention:** Manual checklist + automated tests validate UI integrity
+
+### Refactoring Process
+1. Ensure full test coverage exists (backend 85%, frontend 80%)
+2. Run complete test suite (all tests PASS)
+3. Refactor module: split into smaller files/services
+4. Run test suite again (all tests PASS)
+5. Manual browser validation: UI unchanged, all buttons/features work
+6. Commit with test results in message body
+7. Move to next module
+
+### Module Extraction Patterns
+- **Backend Routers:** Split into router (endpoints only) + service (business logic) + validators (input validation)
+- **Components:** Split into orchestrator component + sub-components + custom hooks for state/logic
+- **Pages:** Extract page logic into custom hooks, move forms into separate components
+- **Utilities:** Consolidate repeated logic into `lib/` or `services/` modules
+
+### Validation Checklist (Post-Refactor)
+- [ ] All pytest tests passing (backend coverage 85%+)
+- [ ] All vitest tests passing (frontend coverage 80%+)
+- [ ] All e2e workflows passing (Playwright)
+- [ ] Login works (LDAP + local)
+- [ ] Scanner functional (scan → match → stock adjustment)
+- [ ] AI extraction working (new item → AI popup → validation)
+- [ ] Admin page responsive and functional
+- [ ] No console errors in browser
+- [ ] Mobile responsive (320px, 768px, 1024px+ viewports)
+- [ ] Keyboard navigation works (focus indicators visible)

+
+---
+
+## 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]
+```
+
+---
+

-### 1. Verify Server Startup Works
+### 1. Verify Server Startup Works (CRITICAL)
 - Run `./start_server.sh` in terminal (requires: python3.12-venv installed via `sudo apt install python3.12-venv`)
 - Verify:

   - HTTPS proxies start (ports 3002-3003)

+- **MUST TEST**: The start_server.sh fixes are now committed in v1.10.16

+### 2. Run Full Audit & Test UX
+- Run `/audit` to confirm improvements (expected: 17+/20)
+- Manual browser testing:
   - Verify removed gradients (Scanner, AIOnboarding, IdentityCheckOverlay)
   - Test scanner responsive behavior (320px, 768px, 1024px+ viewports)
   - Test admin page keyboard navigation (focus indicators on logout button)
   - Verify reduced-motion works: Settings → Accessibility → prefers-reduced-motion
   - Test ConfirmationModal, CreateUserModal keyboard access
 
-### 3. Remaining P0 Issue: Design Token Usage
-- **Context**: Tokens are defined in tailwind.config.ts but not used in components
+### 3. Production Bundle Generation
+- **Note**: export_prod.sh may have had issues in the automated run
+- Manually run `./export_prod.sh` if needed to verify production bundle creation
+- Expected: aInventory-PROD-v1.10.16.zip in root directory
+
+### 4. Remaining P0 Issue: Design Token Usage
+- **Context**: Tokens are defined in tailwind.config.ts but 0 `var(--primary)` references in components
 - **Task**: Manually audit components and replace hard-coded Tailwind classes with CSS variables
 - **Impact**: Would improve design consistency and maintainability
-- **Priority**: Can be deferred to v1.10.13 if time-constrained
+- **Priority**: P0 but can be deferred to v1.10.17 if other priorities emerge
 
-### 4. Optional Enhancements
+### 5. Optional Enhancements
 - **P2**: `/optimize` — Lazy-load tesseract.js (500KB) only when OCR mode activated
 - **P3**: Light mode support (extend tailwind, create toggle)
 - **P3**: More semantic HTML landmarks in other pages (currently only admin has <main>)
 
-### 5. Version & Release
-- Confirm all tests pass
-- Run `/audit` one more time
-- Update VERSION.json (currently v1.10.11 → v1.10.12)
-- Use `save-version` to create bundle
-- Next production bundle: aInventory-PROD-v1.10.12.zip
