# Domain Rules

## Portfolio

### Current implementation

- A project must belong to one category
- Categories cannot be deleted while linked projects exist
- Public portfolio pages only show published projects
- Category filters only use active categories
- Project content is localized across

`ar`

,

`en`

,

`de`

- Project sections and assets are ordered by

`sortOrder`

- Project view mode is limited to:
  - `GRID`
  - `STORY`
  - `CASE_STUDY`

## Media

### Current implementation

- Media assets are tracked separately from portfolio records
- Media usage bindings connect assets to entity fields
- Usage binding is unique by

`usageType + entityType + entityId + fieldKey`

- Media is currently used by:
  - portfolio cover
  - portfolio sections
  - portfolio assets
  - site settings

## Contact

### Current implementation

- Contact submission requires valid name, email, and message (validated with Zod)
- Successful submission sends email only
- No submission record is stored in the database

## Admin

### Current implementation

- Admin access depends on environment configuration
- Middleware can require HTTP Basic Auth before app access
- In-app admin session is cookie-based
- Repeated failed password attempts trigger temporary lockout

## Configuration

### Current implementation

- Global settings are stored in

`AppConfig`

- Site settings, SMTP settings, contact protection, marquee settings, and maintenance mode all depend on configuration keys

## Recommended Improvements

- Add explicit domain rules for future

`products`

,

`orders`

,

`downloads`

only after data models exist
- Introduce database retention and moderation rules for contact or inquiry submissions if they become persisted
