## Flags & Notes for Your Review

### 1. "More Filters" Sub-Fields ✅
**Status:** Clarified in code

Current implementation includes:
- **Amenities**: Pool, Gym, Parking, Security, Garden, Balcony
- **Area**: Studio, 1BR, 2BR, 3BR, 4BR+
- **Developer**: Full list from database
- **Completion Year**: Dynamic list from projects

These are hardcoded in the response but can be made editable in Filament if needed.

### 2. is_favorited Field
**Status:** Not implemented (requires authentication)

Current: All projects return as not favorited (no auth required to view listing)

**To Implement:**
- Requires user authentication
- Track favorites in database
- Return based on logged-in user
- Add favorite/unfavorite endpoints

### 3. Explore by City Links
**Status:** Editable in Filament, currently placeholder URLs

The structure is fully prepared for:
- 4 columns with multiple links each
- Recommended searches group
- Other property types group
- Useful links group

All manageable via Filament admin repeaters.

### 4. FAQ Answers
**Status:** Ready for content

Only first FAQ has an answer (from design). Others are empty in defaults.

Can be populated via:
- Filament admin (repeater UI)
- Direct database insert
- API if needed

### 5. Property Data Source
**Status:** From Goyzer API (cached 1 hour)

The projects data comes from your Goyzer integration. If projects don't appear:
- Check Goyzer API connectivity
- Verify GoyzerService is working
- Cache may need clearing

   - Possibly `/api/v1/contacts` or similar

5. **Add Wishlist** (future)
   - Implement authentication
   - Add favorite/unfavorite endpoints
   - Return `is_favorited` in response
