 ### Phase 2 Review Checklist
 
 When Phase 2 is complete, verify:
-- [ ] All auth pages functional
-- [ ] Forms have proper validation
-- [ ] Error messages are user-friendly
-- [ ] Loading states on all async operations
-- [ ] E2E tests for full auth flows pass
-- [ ] Security audit completed
-- [ ] Accessibility audit completed
-- [ ] No console errors
-- [ ] Works in mobile viewport
-- [ ] Dark mode works on all pages
+- [x] All auth pages functional
+- [x] Forms have proper validation
+- [x] Error messages are user-friendly
+- [x] Loading states on all async operations
+- [ ] E2E tests for full auth flows pass (Deferred to Phase 9)
+- [x] Security audit completed (0 vulnerabilities found)
+- [x] Accessibility audit completed (minor improvements documented)
+- [x] No console errors (runtime clean, development has console.log statements)
+- [ ] Works in mobile viewport (Requires manual testing with running app)
+- [ ] Dark mode works on all pages (Requires manual testing with running app)
 
 **Before proceeding to Phase 3:**
-- [ ] Run multi-agent review
-- [ ] Security audit of auth implementation
-- [ ] E2E test full auth flows
-- [ ] Update this plan with actual progress
+- [x] Run multi-agent review (4 agents: code quality, testing, architecture, documentation)
+- [x] Security audit of auth implementation (0 critical/major issues)
+- [ ] E2E test full auth flows (Deferred to Phase 9 - Playwright)
+- [x] Update this plan with actual progress (COMPLETE)
