|
### Phase 0: Project Documents (2026-03-24)
|
|
|
|
- [x] 0.1: Created DESIGN.md — full technical design covering architecture,
|
|
data model, coordinate system, rendering, input handling, and source tree.
|
|
- [x] 0.2: Created PROJECT_PLAN.md — discrete steps grouped by phase with
|
|
checkboxes and file references.
|
|
- [x] 0.3: Created PROGRESS.md — this file.
|
|
- [x] 0.4: Updated CLAUDE.md — build commands, source tree, project doc
|
|
pointers.

Phase 1: Project Skeleton + Data Layer
|
|
|
|
## Decisions & Deviations
|
|
|
|
- **Language**: Kotlin (chosen over Java for better Compose/coroutine support).
|
|
- **Storage**: Room/SQLite with packed float BLOBs for stroke points.
|
|
- **Palm rejection**: Hardware only (EMR digitizer handles it).
|
|
- **Pressure sensitivity**: None — two fixed pen sizes (0.38mm, 0.5mm).
|
|
- **Coordinate system**: 300 DPI canonical points (scaled to 72 DPI for PDF export).
|
|
- **UI framework**: Compose for chrome, custom View for canvas (Compose
|
|
Canvas lacks MotionEvent access needed for stylus input).
