# CLAUDE.md — Pole Dance Championships App

## Target Vision
See `dancechamp-claude-code/` for full spec (3-app Supabase platform).
Current implementation is a simplified MVP working toward that goal.

## Quick Start

```bash
# Backend
cd backend && .venv/Scripts/python -m uvicorn app.main:app --host 0.0.0.0 --port 8000 --reload

# Mobile (set BASE_URL in src/api/client.ts to LAN IP first)
cd mobile && npx expo start --lan --clear

# Seed test data
cd backend && .venv/Scripts/python seed.py
```

## Current Architecture

- **Backend**: FastAPI + SQLAlchemy 2 (async) + aiosqlite (SQLite dev) + Alembic + bcrypt
- **Mobile**: Expo (blank-typescript) + React Navigation v6 + Zustand + Axios + Ionicons
- **Auth**: JWT access (15min) + refresh token rotation (7 days, SHA-256 hashed in DB)

## Project Layout

```
backend/app/           FastAPI app (models, schemas, routers, crud, services)
backend/alembic/       Async migrations
backend/.venv/         Virtual env (use .venv/Scripts/python)
mobile/src/api/        Axios client + API modules (auth, championships, users)
mobile/src/store/      Zustand auth store
mobile/src/screens/    auth/, championships/, admin/, profile/
mobile/src/navigation/ RootNavigator -> AuthStack | AppStack (Tabs + Detail)
dancechamp-claude-code/ Target spec: SPEC.md, PLAN.md, DATABASE.md, DESIGN-SYSTEM.md, SCREENS.md
```

## Gotchas

- **passlib + bcrypt 5.x incompatible** — use `bcrypt` directly (NOT passlib)
- **Circular import**: auth_service.py must NOT import crud_user
- **SQLAlchemy UUID**: Use `sqlalchemy.Uuid(as_uuid=True)` not `postgresql.UUID`
- **Expo newArchEnabled: true** crashes Expo Go — keep `false` in app.json
- **Stale uvicorn**: Kill with `powershell.exe -NoProfile -Command "Get-Process python | Stop-Process -Force"`
- **BASE_URL**: mobile/src/api/client.ts must use LAN IP (not localhost) for physical devices

## Test Credentials (run seed.py)

```
admin@pole.dev / Admin1234       (admin, approved)
organizer@pole.dev / Org1234     (organizer, approved)
member@pole.dev / Member1234     (member, approved)
```

## API Routes

- Auth: POST /api/v1/auth/{register,login,refresh,logout,me}
- Championships: GET/POST/PATCH/DELETE /api/v1/championships
- Registrations: POST/GET/PATCH/DELETE /api/v1/registrations
- Users (admin): GET /api/v1/users, PATCH /api/v1/users/{id}/{approve,reject}
- Health: GET /internal/health | Swagger: GET /docs

## Code Conventions

- Backend: Pydantic v2 schemas, async SQLAlchemy, `from_attributes = True`
- Mobile: Functional components, Zustand stores, Ionicons for icons
- Registration: members auto-approved, organizers require admin approval
- Tab navigator uses `headerShown: true` for safe area; no manual headings in tab screens

## Environment

- Windows 10, Python 3.12, Node.js
- Docker NOT installed, PostgreSQL NOT installed (use SQLite for dev)
- venv always in backend/.venv
