### Human Verification Required

No human verification required - all issues are compilation errors and clear code problems that prevent basic functionality.

### Gaps Summary

Phase 01 has **6 critical compilation errors** that prevent the authentication system from functioning:

1. **Syntax error in main.dart** - Duplicate builder methods prevent app startup
2. **Conflicting code in signup_page.dart** - Unreachable stub code breaks compilation  
3. **Wrong import path in reset_password_page.dart** - Prevents password reset functionality
4. **TODO comments in router** - Password reset tokens not securely stored
5. **Missing logout UI in home_page.dart** - Users cannot log out from the app
6. **Wrong splash page import path** - Navigation references incorrect file location

The authentication foundation is **75% complete** with solid Supabase integration, proper error handling, and good state management. However, these compilation errors must be fixed before the system can be considered functional.

The core authentication infrastructure (models, repository, provider, login page) is well-implemented and follows clean architecture principles. The issues are primarily in:
- Code cleanup (removing conflicting stub implementations)
- Fixing import paths and syntax errors
- Completing password reset secure storage
- Adding missing UI elements (logout button)
