# Project State

## Project Reference

## Accumulated Context

### Decisions

Decisions are logged in PROJECT.md Key Decisions table.
Recent decisions affecting current work:

- Architecture: Provider pattern for state management (pending implementation)
- Architecture: Speed-adaptive GPS precision with ~10 km/h threshold (pending implementation)
- Architecture: Background GPS only when overlay visible (pending implementation)
- Architecture: Layer-first directory structure (screens/, widgets/, services/, providers/, models/) (pending implementation)
- Architecture: No new dependencies beyond provider package (pending implementation)

### Pending Todos

None yet.

### Blockers/Concerns

**Phase 2 (Provider Migration):**
- HIGH RISK: Async lifecycle complexity — 5+ async patterns must be audited before migration
- Must create manual regression testing checklist before starting Phase 2
- GpsDataManager singleton disposal strategy needs design decision

**Phase 3 (Overlay Refactor):**
- MEDIUM RISK: flutter_overlay_window 0.5.0 has known communication issues
- May need testing on multiple Android versions for reliability
- Overlay status polling alternative needs research (event-based vs 5s polling)

**Phase 4 (GPS Optimization):**
- Speed thresholds (8/12 km/h) need field testing validation
- Android OEM behavior varies (Samsung, Xiaomi duty-cycling differences)
