## What Was Done

### Database Changes (database.py)
- Added `user_id INTEGER DEFAULT 1` to exercise/meal/sleep/weight tables
- Implemented user CRUD functions
- Implemented data clear functions with preview
- Updated all add/get functions to support user_id parameter

### API Changes (app.py)
- Added 7 user management endpoints
- Added 2 data management endpoints
- Updated all GET/POST data endpoints to use active user pattern
- Added Pydantic models: UserResponse, UserInput, DataClearInput

### Tests
- All 15 tests passing (7 UserDB + 2 Migration + 6 DataClear)

## Key Architecture

1. **Active User Pattern**: Only one user active at a time, all data operations scoped to active user
2. **Default user_id = 1**: Backward compatibility with existing data
3. **Data Isolation**: Each user's data completely isolated by user_id

---

## Critical Fix

**Issue:** Missing user_id column in tables
**Solution:** Added `user_id INTEGER DEFAULT 1` to CREATE TABLE statements in init_db()

---

## Next Steps

1. Task 9: Create settings page UI with ui-ux-pro-max design
2. Task 10: Add settings link to navigation
3. Task 11: Run integration tests
