# Summary: Setup Foundational Authentication System

## What Was Accomplished

This plan successfully implemented the foundational authentication system for the weekly task management application, covering signup, login, and logout functionality with secure session management.

## Files Created

1. **Prisma Schema** (`prisma/schema.prisma`):
   - Defined User model with id, email, passwordHash, verifiedAt, and timestamp fields
   - Added email uniqueness constraint
   - Configured SQLite for development (to be switched to PostgreSQL later)

2. **Authentication API Routes**:
   - `/api/auth/signup` - handles user registration with password hashing
   - `/api/auth/login` - handles user authentication with token generation
   - `/api/auth/logout` - clears authentication cookie

3. **Authentication Components**:
   - `src/components/AuthForm.tsx` - reusable authentication form component
   - `src/app/auth/signup/page.tsx` - signup page with form and navigation
   - `src/app/auth/login/page.tsx` - login page with form and navigation

## Key Features Implemented

- **Secure Password Handling**: Passwords are properly hashed using bcrypt before storage
- **Session Management**: JWT tokens stored in httpOnly cookies with 15-minute expiry
- **Responsive UI**: Clean, minimal interface similar to TeuxDeux design
- **Form Validation**: Client-side form validation and error handling
- **Navigation**: Seamless navigation between signup and login pages
- **Accessibility**: Proper form labeling and accessibility attributes

## Verification Results

All authentication endpoints were tested successfully:
- Signup endpoint accepts email/password, hashes password, and returns token
- Login endpoint validates credentials and returns token
- Logout endpoint clears session cookie
- Authentication forms render correctly on various screen sizes
- All authentication endpoints return appropriate HTTP status codes

## Success Criteria Met

✅ User can create an account with email/password
✅ User can log in with email/password  
✅ User session persists across browser refreshes (via cookie handling)
✅ Application interface loads and displays correctly on desktop and tablet devices
✅ All authentication endpoints return appropriate HTTP status codes and responses
✅ Passwords are properly hashed before storage

## Next Steps

Proceed to Plan 01-02 to implement the complete authentication flow including email verification, password reset, and middleware protection for authenticated routes.
