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 Complete - Manual Testing Needed:
- 02-01 complete — Provider infrastructure created (7.7 min)
- 02-02 complete — MultiProvider wiring and screen migration (3.8 min)
- All shared state moved to Provider pattern
- Zero setState calls for shared state (only _errorMessage local state)
- Manual testing: Settings persistence, theme/unit cycling, overlay toggle, background heartbeat
- Manual testing: Verify no "setState after dispose" or "ChangeNotifier after dispose" errors
Phase 3 Complete:
- 03-01 complete — Overlay foundation infrastructure (4.0 min)
- 03-02 complete — Overlay integration with staleness detection (4.25 min)
- OverlayProvider delegates all platform calls to OverlayService
- Permission checks before overlay creation, verified creation via isActive()
- Staleness detection: dim at 3s, dashes at 10s, immediate snap-back
- Error surfacing via snackbar with Settings action for permission errors
- GPS grace period timer (30s) infrastructure for Phase 4
- Manual testing: Verify overlay reliability improvements on physical device
- Manual testing: Test permission error snackbar and Settings action button
- Manual testing: Verify staleness dimming and dash display timing
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.yamlexclusion 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 (Complete):
- RESOLVED: Provider infrastructure complete — 3 ChangeNotifier classes created
- RESOLVED: MultiProvider wiring complete with pre-initialized SharedPreferences
- RESOLVED: SpeedometerScreen migrated to Provider pattern (799 lines → 493 lines, -38%)
- RESOLVED: Zero setState calls for shared state (theme, unit, GPS data, overlay status)
- INFO: Manual testing needed to verify settings persistence and provider lifecycle
Phase 3 (Overlay Refactor) — Complete:
- RESOLVED: OverlayService foundation complete with retry logic
- RESOLVED: OverlayProvider integration complete with permission checks and verified creation
- RESOLVED: Staleness detection complete (3s dim, 10s dash, immediate snap-back)
- RESOLVED: Error surfacing complete (snackbar with Settings action for permission errors)
- RESOLVED: GPS grace period timer infrastructure created for Phase 4
- MEDIUM RISK: flutter_overlay_window 0.5.0 has known communication issues (mitigated by retry + verification)
- INFO: Manual testing needed to verify overlay reliability improvements on physical device
- INFO: All OVRL-01 through OVRL-06 requirements satisfied
Phase 4 (GPS Optimization) - Complete:
- RESOLVED: Core GPS engine complete with lifecycle awareness and precision switching
- RESOLVED: ProcessedGpsData timestamp field added for staleness detection
- RESOLVED: Background grace period (7s) with race condition protection
- RESOLVED: Conditional wake lock (GPS active + visible)
- RESOLVED: Plan 04-01 complete (4.9 min) — Core GPS engine with lifecycle
- RESOLVED: Plan 04-02 complete (3.35 min) — UI integration with staleness detection
- RESOLVED: SpeedometerScreen staleness detection added (3s dim, 10s dash)
- RESOLVED: Wake lock and lifecycle centralized in GpsDataManager
- RESOLVED: OverlayProvider grace period placeholder removed
- FIELD TESTING: Speed thresholds (8/12 km/h) need validation on physical device
- FIELD TESTING: Staleness behavior (3s/10s) needs verification during signal loss
- FIELD TESTING: Android OEM behavior varies (Samsung, Xiaomi duty-cycling differences)
