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
|
|
|
|
## Current Position
|
|
|
|
**Phase:** 1 - Semantic Position Model
|
|
**Plan:** Not yet created
|
|
**Status:** Awaiting plan creation

## Accumulated Context
|
|
|
|
### 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.
