+# Copilot Instructions for Strezless Musick Productionz
+
+## Project Overview
+Strezless is a music production business management platform. This repository provides a backend API for managing artist profiles, music releases, distribution, and music industry business documentation.
+
+**Domain Context**: Music business operations, including artist rights management, split sheets, PRO (Performance Rights Organization) registration, and industry standard identifiers (IPI, ISNI, ISRC, ISWC, UPC).
+
+## Tech Stack
+- **Runtime**: Node.js (CommonJS modules)
+- **Framework**: Express.js 5.x
+- **Database**: PostgreSQL with UUID primary keys
+- **Environment**: dotenv for configuration (.env.local)
+- **Key Dependencies**:
+  - `pg` for PostgreSQL connection pooling
+  - `body-parser` for request parsing
+  - `express` for REST API
+

+
+## Development Workflow
+
+### Running the Application
+```bash
+# Install dependencies
+npm install
+
+# Development server (default port 3000)
+npm run dev
+
+# The server runs at http://localhost:3000
+```
+
+### Environment Variables
+Required in `.env.local`:
+- `DATABASE_URL`: PostgreSQL connection string
+- `PORT`: Server port (optional, defaults to 3000)
+- `NODE_ENV`: Environment (development/production)
+
+### API Endpoints
+Base URL: `http://localhost:3000`
+
+- `POST /api/artist/profile` - Create artist profile
+- `GET /api/artist/profile/:id` - Get artist profile
+- `PUT /api/artist/profile/:id` - Update artist profile
+- `PUT /api/artist/identifiers/:artistId` - Update industry identifiers
+- `GET /api/artist/search` - Search artists by identifiers
+- `GET /health` - Health check endpoint
+
+## Coding Standards & Conventions
+
+### JavaScript Style
+- Use CommonJS modules (`require`/`module.exports`)
+- Use `async/await` for asynchronous operations
+- Always use transaction blocks (BEGIN/COMMIT/ROLLBACK) for multi-step database operations
+- Use connection pooling (`pool.connect()`) with proper client release in `finally` blocks
+- Include JSDoc comments for route handlers
+- Use destructuring for request parameters
+
+### Database Conventions
+- **Primary Keys**: Use UUID with `gen_random_uuid()`
+- **Timestamps**: Include `created_at` and `updated_at` (auto-managed by triggers)
+- **Naming**: Use snake_case for column names, plural for table names
+- **Industry Identifiers**:
+  - IPI (Interested Parties Information): 9 numeric digits plus 2 check digits (11 characters total with formatting)
+  - ISNI (International Standard Name Identifier): 16 digits
+  - ISRC (International Standard Recording Code): 12 characters (format: CC-XXX-YY-NNNNN)
+  - ISWC (International Standard Musical Work Code): Format T-XXXXXXXXX-C (11 characters including prefix T and check digit)
+  - UPC (Universal Product Code): 12 digits
+  - EIN (Employer Identification Number): US tax ID (format: XX-XXXXXXX)
+
+### Error Handling
+- Always wrap async database operations in try/catch
+- Use transaction rollback on errors
+- Return JSON responses with consistent format:
+  ```javascript
+  {
+    success: true/false,
+    data: {...},        // on success
+    message: "...",     // descriptive message
+    error: "..."        // error details (development only)
+  }
+  ```
+- Log errors with `console.error()` before sending response
+- Use appropriate HTTP status codes (201 for created, 404 for not found, 500 for server errors)
+
+### API Response Format
+All API responses should follow this structure:
+```javascript
+{
+  success: boolean,
+  data?: object | array,
+  message?: string,
+  error?: string,
+  count?: number  // for list/search endpoints
+}
+```
+
+### CORS Configuration
+- Development: Allow all origins (configured in index.js)
+- Production: Configure CORS properly with specific origins
+
+## Music Industry Specific Guidelines
+
+### Artist Profiles
+- `career_level` must be one of: 'emerging', 'indie', 'established', 'professional', 'signed'
+- Always validate industry identifiers format before storing
+- Email is required and unique across artists
+- Genres are stored as PostgreSQL arrays
+
+### Releases & Tracks
+- `release_type` options: 'single', 'ep', 'album', 'compilation', 'live'
+- `distribution_status`: 'draft', 'submitted', 'processing', 'live', 'taken_down'
+- ISRC codes are mandatory and unique for each track
+- DDEX compliance tracking is required for distribution
+
+### Split Sheets & Contributors
+- Ownership percentages must sum to 100% for each track
+- `role` options: 'writer', 'composer', 'producer', 'performer', 'featured_artist'
+- `split_type` categories: 'publishing', 'master', 'performance'
+- Always store contributor IPI/ISNI if available
+
+### Documentation
+- Split sheets are in `/docs/splits/`
+- Legal templates are in `/docs/legal/`
+- Maintain markdown format for all documentation
+- Follow existing template structure when adding new documents
+
+## Security Requirements
+- Never commit sensitive data (API keys, database credentials, etc.)
+- Use environment variables for all sensitive configuration
+- Validate all user input before database queries
+- Use parameterized queries to prevent SQL injection
+- Store hashed passwords only (when authentication is added)
+- Configure SSL for production database connections
+
+## Testing
+Current state: No test infrastructure exists yet.
+When adding tests in the future:
+- Consider using Jest or Mocha for testing
+- Test database operations with a test database
+- Mock external API calls
+- Test validation logic thoroughly
+
+## Dependencies
+- Avoid adding new dependencies unless absolutely necessary
+- When adding dependencies, ensure they are actively maintained
+- Review security advisories before adding packages
+- Update package.json and package-lock.json together
+
+## Important Notes
+- This is a music business application - understand the domain context (PRO registration, split sheets, publishing rights)
+- Industry identifiers (IPI, ISNI, ISRC, etc.) follow international standards - validate format
+- Transaction integrity is critical for artist profile and identifier operations
+- Social links are stored as JSONB for flexibility
+- Always release database clients in finally blocks
+- The application uses Express 5.x (note differences from Express 4.x)
+
+## Common Tasks
+
+### Adding a New API Endpoint
+1. Add route handler in appropriate file in `/routes/`
+2. Include JSDoc comment describing the endpoint
+3. Use async/await with proper error handling
+4. Follow consistent response format
+5. Release database connections properly
+
+### Adding Database Tables
+1. Update `/database/schema.sql`
+2. Add appropriate indexes for foreign keys and frequently queried columns
+3. Include `created_at` and `updated_at` timestamps
+4. Add trigger for auto-updating `updated_at`
+5. Use UUID for primary keys
+
+### Working with Music Business Documentation
+1. Follow existing markdown template structure
+2. Store in appropriate `/docs/` subdirectory
+3. Reference relevant PRO requirements and industry standards
+4. Include examples where helpful
