Phases: 1. Semantic Position Model: DATA-*, PERS-* (foundation) 2. Constraint Validation: CONS-* (rules engine) 3. Visual Flattening: FLAT-* (display bridge) 4. Drag Interaction: DRAG-* (UI layer) All 23 v1 requirements mapped to phases.

Project Reference
Core Value: Drag-and-drop that operates on semantic positions (day + sortOrder), not row indices - so user intent is preserved across data reloads.
Current Focus: Beginning Phase 1 - Semantic Position Model

Key Decisions
| Decision | Rationale | Phase |
|---|---|---|
| UITableView over SwiftUI List | SwiftUI drag-drop lacks insertion line precision | Pre-planning |
| (day, sortOrder) position model | Row indices break on reload; semantic position is stable | Pre-planning |
| Insertion lines (not zones) | User wants precise feedback on exact drop location | Pre-planning |
| Invalid drops rejected (snap back) | Cleaner than auto-clamping; user knows what happened | Pre-planning |
Learned
- Previous attempts failed due to row-based thinking instead of semantic positioning
- Travel was incorrectly treated as structural ("travelBefore") instead of positional
- Hard-coded flatten order ignoring sortOrder caused reload issues
TODOs
None yet - awaiting Phase 1 planning.
Blockers
None currently.
Session Continuity
Last Session: Project initialized, roadmap created Next Action: Create plan for Phase 1
Context for Next Session
Starting fresh. Phase 1 establishes the semantic position model that everything else depends on. Requirements DATA-01 through DATA-05 define the model structure, PERS-01 through PERS-03 define persistence behavior. The key insight from research: row indices are lies, semantic positions are truth.
