 ## Phase 5: AST Slice Pre-population
 Focus: Show auto-resolved slices before user customizes
 
-- [ ] Task 5.1: On file add to context, compute AST slices automatically
-- [ ] Task 5.2: Store pre-computed slices in FileItem for display
-- [ ] Task 5.3: User can modify/remove auto-slices
-- [ ] Task 5.4: Write tests for auto-slice computation
