# Project State

## Project Reference

See: .planning/PROJECT.md (updated 2026-02-09)

**Core value:** Reliable, lag-free GPS speed display that coexists politely with other Android apps
**Current focus:** Phase 2 - Provider Migration (planned, ready to execute)

## Current Position

Phase: 2 of 4 (Provider Migration)
Plan: 0 of 2 complete
Status: Planned — research, context, and 2 plans created and verified
Last activity: 2026-02-10 — Completed /gsd:plan-phase 2

Progress: [░░░░░░░░░░] 0% (Phase 2: 0/2 plans)

## Performance Metrics

**Velocity:**
- Total plans completed: 2
- Average duration: 9.8 minutes
- Total execution time: 0.33 hours

**By Phase:**

| Phase | Plans | Total | Avg/Plan |
|-------|-------|-------|----------|
| 1. Foundation | 2 | 19.6 min | 9.8 min |

**Recent Trend:**
- Last 5 plans: 01-01 (12.8 min), 01-02 (6.8 min)
- Trend: Accelerating (47% faster on plan 2)

### Pending Todos

**Phase 1 Complete - Verification Needed:**
- [ ] Run full functionality test on physical Android device (non-blocking checkpoint from 01-02)
- [ ] Verify speed display, theme/unit cycling, overlay launch/close, landscape mode
- [ ] Confirm Logger output format in debug console

**Phase 2 Planning Complete:**
- [x] Research completed (02-RESEARCH.md) — Provider v6.1.5+1, 7 pitfalls identified
- [x] Context gathered (02-CONTEXT.md) — user decisions locked
- [x] Plans created and verified (02-01-PLAN.md, 02-02-PLAN.md)
- [x] GpsDataManager singleton disposal strategy decided: extends ChangeNotifier, singleton removed, _isDisposed guard

### Blockers/Concerns

**Phase 1 (Complete):**
- RESOLVED: All structural requirements (ORG-01 through ORG-08) satisfied
- LOW: SCREAMING_SNAKE analyzer warnings (21 intentional info-level warnings) — Consider `analysis_options.yaml` exclusion if noise becomes issue
- LOW: Logger severity level guidelines should be documented for contributors
- INFO: Phase 1 functionality testing deferred to user-initiated session (non-blocking checkpoint)

**Phase 2 (Provider Migration) — Planned:**
- MITIGATED: Async lifecycle complexity addressed via _isDisposed guards on all providers
- RESOLVED: GpsDataManager singleton removal planned — public constructor, Provider-managed lifecycle
- NOTE: Trip tracking code confirmed absent from codebase — no removal needed

**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)
