Critical Checklist

1. Security and Data Isolation

• ALL queries filter by tenant/organization (if multi-tenant)
• ALL queries filter soft-deleted records (if applicable)
• No cross-tenant data access
• Auth guards on protected routes
• Input validation via DTOs/schemas

2. TypeScript

• No any types — define proper interfaces
• Interfaces/props in dedicated files, not inline
• Return types on all functions
• No console.log — use project logger

5. Error Handling

• Try/catch blocks present
• Framework-specific exceptions (not generic Error)
• Errors logged via logger service
• Generic messages to client (no internals exposed)

6. Testing

• Unit tests exist and pass
• All public methods tested
• Error cases tested
• Coverage > 70% for new code

7. Frontend
