## Summary: Phase 1, Plan 1 - Authentication Foundation

This plan implemented the foundational authentication system for the weekly task management application, establishing the core user management and session handling capabilities.

### Key Deliverables

1. **Prisma User Model**: Created a complete User model with id, email, passwordHash, verifiedAt, createdAt, and updatedAt fields, including unique constraint on email.

2. **Authentication API Endpoints**:
   - POST `/api/auth/signup` - handles user registration with password hashing
   - POST `/api/auth/login` - handles user authentication with JWT token generation
   - POST `/api/auth/logout` - handles user session termination

3. **Reusable Authentication Component**:
   - Created `AuthForm.tsx` component with responsive design
   - Implemented form validation and error handling
   - Built with accessibility considerations

### Implementation Details

The authentication system uses:
- JWT tokens stored in httpOnly cookies for secure session management
- jose library for JWT handling (avoiding CommonJS issues with Edge runtime)
- bcrypt for password hashing
- Prisma ORM for database interactions

### Verification

All endpoints were tested and verified to:
- Properly handle signup, login, and logout flows
- Return appropriate HTTP status codes
- Store passwords securely with hashing
- Manage sessions across browser refreshes
- Render correctly on desktop and tablet devices

This foundation enables the complete authentication flow for users to create accounts, log in, and maintain sessions throughout their browsing experience.
