+
+## Accomplishments
+
+### Infrastructure Created
+
+**1. Logger Utility (`lib/services/logger.dart`)**
+- 4 severity levels: error (red), warn (yellow), info (blue), debug (gray)
+- ANSI color-coded output with ISO 8601 timestamps
+- Optional caller tags: `Logger.error('message', 'GpsDataManager')`
+- All output guarded by `kDebugMode` to avoid production logs
+- Uses `debugPrint()` to prevent log truncation
+- Replaces 106+ print/customDebugPrint calls across codebase
+
+**2. Constants Files (SCREAMING_SNAKE naming)**
+
+**`lib/config/gps_constants.dart` (GpsConfig):**
+- `STALE_DATA_THRESHOLD`: 4s before marking GPS data stale
+- `INITIAL_FIX_TIMEOUT`: 20s for cold start GPS acquisition
+- `UPDATE_TIMEOUT`: 2s for ongoing updates (indoor detection)
+- `VALID_HEADING_MIN/MAX`: 0-360° heading range validation
+- `LOW_SPEED_THRESHOLD`: 1.0 m/s below which heading unreliable
+
+**`lib/config/timing_constants.dart` (TimingConfig):**
+- `HEARTBEAT_INTERVAL`: 5s background keepalive when overlay active
+- `OVERLAY_STATUS_CHECK_INTERVAL`: 1s polling for overlay status
+- `TAP_CLOSE_DELAY`: 500ms debounce for tap-to-close
+- `LONG_PRESS_SIGNAL_DELAY`: 50ms IPC signal propagation delay
+
+**`lib/config/overlay_constants.dart` (OverlayConfig):**
+- `WIDTH_PERCENTAGE`: 0.45 (overlay 45% of screen width)
+- `ASPECT_RATIO`: 0.6 (height = 60% of width)
+- `BACKGROUND_OPACITY`: 0.85
+- `BORDER_OPACITY`: 0.3
+- `FONT_SIZE_RATIO`: 0.2 (speed font = 20% of overlay width)
+- `UNIT_FONT_RATIO`: 0.6 (unit text = 60% of speed font)
+- `ICON_SIZE_RATIO`: 0.72 (navigation icon = 72% of speed font)
+- `HEADING_FONT_RATIO`: 0.4 (heading text = 40% of speed font)
+- `DEFAULT_SCREEN_WIDTH/OVERLAY_WIDTH/HEIGHT`: Fallback dimensions
+
+**3. Data Models**
+
+**`lib/models/processed_gps_data.dart` (ProcessedGpsData):**
+- Extracted from gps_data_manager.dart (lines 6-40)
+- Immutable with copyWith() method
+- Fields: speed, heading, displaySpeed, displayHeading, isSpeedValid, isHeadingValid
+- Pure Dart class, no Flutter dependencies
+
+**`lib/models/overlay_message.dart` (OverlayMessage):**
+- Typed replacement for unvalidated Map IPC data
+- Fields: action, speedText, unitText, headingText, heading, unitIndex, themeIndex, overlayWidth, overlayHeight
+- Factory constructors: `updateDisplay()`, `longPressClose()`, `overlayClosed()`
+- Serialization: `toMap()` / `fromMap()` for FlutterOverlayWindow IPC
+- Eliminates Map key typos, provides compile-time type safety
+
+**`lib/models/theme_model.dart` (ThemeModel):**
+- Wraps ColorThemes with state management
+- Exposes: `current` (ColorTheme), `currentSetName` (String), `currentIndex` (int)
+- Methods: `rotate()` for circular theme cycling, `copyWith()` for state updates
+- Delegates palette storage to ColorThemes (avoids duplication)
+
+**4. Config Files Moved**
+
+**`lib/config/speed_unit.dart`:**
+- Moved from lib/speed_units.dart (old file deleted)
+- SpeedUnit enum with label, multiplier, convert(), next() methods
+- All imports updated from 'speed_units.dart' to 'config/speed_unit.dart'
+
+**`lib/config/color_themes.dart`:**
+- Moved from lib/color_themes.dart (old file deleted)
+- ColorTheme + ColorThemes classes with 4 palettes
+- All imports updated from 'color_themes.dart' to 'config/color_themes.dart'
+
+**5. Directory Structure**
+
+Created layer-first architecture:
+- `lib/screens/` - UI screens (future SpeedScreen, SettingsScreen)
+- `lib/widgets/` - Reusable widgets (future SpeedDisplay, GaugeWidget)
+- `lib/providers/` - State management providers (future GpsProvider, ThemeProvider)
+- `lib/models/` - Data models (ProcessedGpsData, OverlayMessage, ThemeModel)
+- `lib/config/` - Configuration constants and enums
+- `lib/services/` - Business logic services (already existed)

+
+## Decisions Made
+
+**1. SCREAMING_SNAKE naming for behavioral constants**
+- **Context:** Need consistent naming pattern to distinguish config constants from regular variables
+- **Decision:** Use SCREAMING_SNAKE_CASE for all constants in config/ files
+- **Rationale:** Per PROJECT.md Key Decisions table - matches backend convention, highly visible in code, clear intent
+- **Impact:** Triggers analyzer info warnings (intentional), all future constants follow this pattern
+- **Trade-offs:** Deviates from Dart style guide (lowerCamelCase), but project convention takes precedence
+
+**2. Logger replaces print()/customDebugPrint() globally**
+- **Context:** 106+ print/customDebugPrint calls across codebase with inconsistent formatting
+- **Decision:** Create Logger utility with 4 severity levels (error, warn, info, debug), ANSI color coding, timestamps, caller tags
+- **Rationale:** Standardized logging improves debugging, severity levels enable filtering, color coding improves readability, kDebugMode guards prevent production logs
+- **Impact:** All future code uses Logger.error/warn/info/debug, zero bare print() calls allowed
+- **Trade-offs:** Slightly more verbose than print(), but significantly better maintainability
+
+**3. OverlayMessage typed class for IPC**
+- **Context:** Overlay communication uses raw Map with string keys like `{'action': 'updateDisplay', 'speedText': '42.5', ...}`
+- **Decision:** Create typed OverlayMessage class with toMap()/fromMap() serialization, factory constructors for common patterns
+- **Rationale:** Type safety eliminates Map key typos (compile-time vs runtime errors), factory constructors enforce correct message structure, self-documenting API
+- **Impact:** All overlay communication uses OverlayMessage.updateDisplay(...).toMap() and OverlayMessage.fromMap(data)
+- **Trade-offs:** Adds one class, but prevents entire category of runtime bugs
+
+**4. ThemeModel delegates to ColorThemes**
+- **Context:** User mental model: "ThemeModel holds all palettes, exposes current set, has rotate() method"
+- **Decision:** ThemeModel wraps ColorThemes (which holds static palette list), exposes `current` property and `rotate()` method
+- **Rationale:** Delegation pattern avoids duplicating static palette data while providing the API user expects, separation of concerns (ColorThemes = data, ThemeModel = behavior)
+- **Impact:** Future theme management extends ThemeModel, ColorThemes remains unchanged
+- **Trade-offs:** Adds indirection layer, but better separation of concerns
+
+**5. Layer-first directory structure**
+- **Context:** Need modular architecture for Phase 2 provider migration
+- **Decision:** Create screens/, widgets/, providers/, models/, config/, services/ directories
+- **Rationale:** Layer-first (vs feature-first) matches small app size, clear separation of concerns, aligns with Provider pattern migration in Phase 2
+- **Impact:** All future code organized by layer, easy to find files by responsibility
+- **Trade-offs:** Slightly longer import paths, but better organization as app grows
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+All tasks completed successfully:
+- Task 1: Directory structure, Logger, 3 constants files created
+- Task 2: 2 config files moved, 3 data models extracted
+- Task 3: All imports rewired, 106+ logging calls replaced, 2 old files deleted
+
+## Issues Encountered
+
+**Issue 1: Missing ProcessedGpsData import in main.dart**
+- **Discovered:** During Task 3 verification, flutter analyze showed "Undefined class 'ProcessedGpsData'" errors
+- **Root cause:** Forgot to add `import 'models/processed_gps_data.dart';` when updating main.dart imports
+- **Resolution:** Added missing import, analyzer errors cleared immediately
+- **Category:** Rule 1 (Bug) - Missing critical import
+- **Impact:** 2-minute fix, no architectural changes
+
+**No other issues encountered.** Plan was well-structured with clear, atomic tasks. All verification checks passed.
+
+## Next Phase Readiness
+
+**Phase 1 Plan 02 prerequisites: ✅ READY**
+- Logger utility available for all future code
+- Constants files ready to use in remaining Phase 1 plans
+- Models extracted and ready for provider integration
+- Directory structure established for widget/screen extraction
+
+**Blockers for future plans:** None
+
+**Concerns:**
+- **SCREAMING_SNAKE analyzer warnings:** 21 info-level "constant_identifier_names" warnings intentional per project convention. These are NOT errors and do not affect compilation. Future plans will add more SCREAMING_SNAKE constants, increasing warning count. Consider adding `analysis_options.yaml` rule exclusion if warnings become noise.
+
+**Recommendations:**
+- Consider adding `analysis_options.yaml` to suppress `constant_identifier_names` warnings for config/ directory
+- Document Logger severity level usage guidelines in CONTRIBUTING.md (when to use error vs warn vs info vs debug)
+- Consider adding Logger.trace() level for ultra-verbose GPS coordinate logging if needed in Phase 4
+
+**Ready to proceed with Phase 1 Plan 02.**
