## Critical Notes for Agents

### Frontend Code Location
**ALL React components, pages, and UI code are in `client/` folder.**
- Pages: `client/pages/*.jsx`
- Components: `client/components/**/*.jsx`
- Hooks: `client/hooks/*.js`
- API client: `client/api.js`
- Router: `client/App.jsx`

### Backend Code Location
**ALL backend code is at root or in server folders:**
- Entry: `server.js`
- Routes: `routes/*.js`
- Services: `services/*.js`
- Middleware: `middleware/*.js`
- Database: `db/*.js`

## Agent Review Roles

| Agent | Role | Focus Area |
|-------|------|------------|
| Neo | Backend / System Architecture | server.js, routes/, services/, middleware/, workers/, db/, Docker, performance, scalability, security |
| Scarlett | UI/UX / Frontend | client/, public/, components, styling, accessibility, responsive design |
| Bishop | Analysis / Code Quality | overall architecture, patterns, maintainability, technical debt |
| Private_Hudson | Security / Compliance | auth, data protection, input validation, compliance |

### Cross-Cutting Concerns
All agents must be aware of:
- **Routing**: `client/App.jsx` defines all frontend routes
- **Auth**: `client/hooks/useAuth.jsx` and `services/authService.js`
- **API**: `client/api.js` mirrors `routes/` structure
- **Database**: `db/database.js` schema affects both frontend and backend

## Review Output
All findings appended to `REVIEW.md` per agent section.
