# 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 (next)

## Current Position

Phase: 1 of 4 (Foundation)
Plan: 2 of 2 complete (01-02)
Status: Phase complete
Last activity: 2026-02-09 — Completed 01-02-PLAN.md

Progress: [██████████] 100% (Phase 1: 2/2 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)

| All   | All   | No new dependencies beyond provider package           | In progress    |

### 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 Pre-work:**
- [ ] Create manual regression testing checklist before provider migration
- [ ] Audit 5+ async patterns in SpeedometerScreen for provider compatibility
- [ ] Design GpsDataManager singleton disposal strategy

### 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):**
- 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)
