8. Create ClipType, MediaAsset (URL, type, duration, thumbnail, observable), and Timeline (FPS, dimensions, tracks).
9. 
   
10. Keep Timeline as a struct for diffs and undo/redo; use reference types for thumbnails.
11. 
    
12. Expose an Agent toolkit: analyzeAsset, organizeLibrary, generateMedia, editMedia.
13. 
    
14. Wire tools into context menus and a conversational agent UI for natural prompts.
15. 
    

UX Principles: Automation with Control

Key Takeaway: Keep AI visible, optional, and always reversible.
