@Model final class Project {

    var type: ProjectType  // prose, poetry, drama
    var creationDate: Date
    var details: String?
    @Relationship(deleteRule: .cascade)

🎓 How This Was Built

Methodology: Test-Driven Development (TDD)

1. Write specification (requirements, user stories)
2. Write tests for each feature
3. Implement code to pass tests
4. Refactor for clarity
5. Document decisions

Phase Progression

Phase 001 (Project Management)
│
├── T001-T026: Project CRUD operations
├── T005-T022: UI components and views
├── T012-T026: 45 comprehensive tests
└── Result: Working project management ✅

Phase 002 (Folder & File Management) 
│
├── T001-T008: Template service
├── T009-T050: Folder management UI
├── T051-T085: File management UI
├── T001-T019: 21 comprehensive tests
└── Result: Working folder/file management ✅

Total: 66 tests, ~4,000 LOC

🐛 Debugging Guide

Common Issues

Folder count wrong (15 instead of 3)?

• Root cause: SubFolders incorrectly assigned to project.folders
• Solution: Don't set project reference on subfolders
• File: services/ProjectTemplateService.swift

Navigation loop when tapping folders?

• Root cause: SwiftData predicates with optional chaining failing
• Solution: Use direct property access instead of @Query predicates
• File: Views/FolderListView.swift

Info sheet blank?

• Root cause: Using .constant() bindings instead of state
• Solution: Pass actual $stateVariable bindings
• File: Views/ProjectDetailView.swift

Build fails?

• Solution: ⌘+Shift+K (clean build), then ⌘+B
• Check: CloudKit entitlements enabled

See IMPLEMENTATION_GUIDE.md for complete debugging guide.
