### Requirements Coverage
| Requirement | Status | Evidence |
|-------------|--------|----------|
| ORG-01: Directory structure (screens/, widgets/, providers/, services/, models/, config/) | SATISFIED | All 6 directories exist and populated appropriately |
| ORG-02: ProcessedGpsData model extracted to models/ | SATISFIED | lib/models/processed_gps_data.dart exists with 36 lines, imported by gps_data_manager and speedometer_screen |
| ORG-03: SpeedUnit and ColorTheme moved to config/ | SATISFIED | Both files exist in lib/config/, old files deleted |
| ORG-04: Constants file with magic numbers | SATISFIED | 3 constants files created (GpsConfig, TimingConfig, OverlayConfig) with SCREAMING_SNAKE naming |
| ORG-05: Typed OverlayMessage class | SATISFIED | lib/models/overlay_message.dart with toMap()/fromMap() replaces raw Maps |
| ORG-06: All print() replaced with Logger | SATISFIED | Logger utility exists, 100 usages found, 0 bare print() calls (6 commented customDebugPrint references are legacy comments) |
| ORG-07: SpeedometerScreen extracted | SATISFIED | lib/screens/speedometer_screen.dart (798 lines) contains SpeedometerScreen class |
| ORG-08: OverlaySpeedometer extracted | SATISFIED | lib/screens/overlay_screen.dart (302 lines) contains OverlaySpeedometer class |
**All 8 Phase 1 requirements SATISFIED.**
### Anti-Patterns Found
| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| None | - | - | - | No blocking anti-patterns detected |
**Notes:**
- 21 info-level analyzer warnings for SCREAMING_SNAKE constant naming are intentional per project convention
- 1 unnecessary_import warning for flutter/foundation.dart in main.dart is cosmetic
- 6 commented-out customDebugPrint references in overlay_screen.dart are legacy debug code, not active
### Human Verification Required
**Note:** Plan 01-02 includes a non-blocking checkpoint for human verification. The following tests should be performed when convenient to confirm behavioral equivalence:
#### 1. Basic GPS Speed Display
**Test:** Run app on physical Android device with GPS enabled, move around
**Expected:** Speed displays current GPS speed or '--' when stationary/no fix
**Why human:** Requires physical device movement and GPS hardware
#### 2. Theme Cycling
**Test:** Tap the speed number repeatedly
**Expected:** Cycles through themes: Yuzuki -> Yuuparo -> Yuzuki Light -> Yuuparo Light -> back to Yuzuki
**Why human:** Visual color changes and haptic feedback require human observation
#### 3. Unit Cycling
**Test:** Tap the unit label (km/h) repeatedly
**Expected:** Cycles through units: km/h -> mph -> kts -> back to km/h, speed value updates
**Why human:** Requires observing unit text changes and recalculated values
#### 4. Overlay Launch
**Test:** Tap the compass/navigation area in bottom right
**Expected:** Floating overlay window appears on top of other apps showing speed and heading
**Why human:** System-level overlay requires visual confirmation across app boundaries
#### 5. Overlay Data Sync
**Test:** With overlay open, observe speed and theme changes in both main app and overlay
**Expected:** Both displays show identical data (speed, heading, theme colors)
**Why human:** Requires comparing two simultaneous displays
#### 6. Overlay Close
**Test:** Long-press the overlay window
**Expected:** Overlay closes, main app brought to foreground
**Why human:** Gesture interaction and focus change require human observation
#### 7. Landscape Mode
**Test:** Rotate device to landscape orientation
**Expected:** Layout adjusts to landscape (both main app and overlay)
**Why human:** Visual layout changes require human observation
#### 8. Logger Output Format
**Test:** Check debug console during app operation
**Expected:** Colored log output with [ERROR]/[WARN]/[INFO]/[DEBUG] tags, ISO 8601 timestamps, caller tags like [GpsDataManager]
**Why human:** Terminal color output and log formatting best verified by human
