## Current Task Goal
Section 7.4 Trip Reporting & Enhanced Tracks — COMPLETE (2026-04-04)

## Verified (2026-04-04)
- Build Successful: `android-app/gradlew assembleDebug` passed.
- UI Layout: `activity_main.xml` refactored to LinearLayout to prevent BottomNav overlap.
- Track Differentiation: Active (solid) vs Past (dotted) tracks verified in `MapHandler.kt`.
- Pre-Trip Logic: Sail suggestions reefing logic verified in `PreTripReportGenerator.kt`.

## Completed Items

### [APPROVED] Trip Narrative Generator + Multi-Style AI (2026-04-04)
- `android-app/app/src/main/kotlin/org/terst/nav/tripreport/TripReportGenerator.kt`: Logic for distance, speed, and stylized narratives (Professional, Adventurous, Journal, Pirate).
- `android-app/app/src/main/kotlin/org/terst/nav/tripreport/TripReportViewModel.kt`: State management for narrative generation.
- `android-app/app/src/main/kotlin/org/terst/nav/tripreport/TripReportFragment.kt`: UI for viewing and selecting narrative styles.

### [APPROVED] Pre-Trip Planning & Sail Suggestions (2026-04-04)
- `android-app/app/src/main/kotlin/org/terst/nav/tripreport/PreTripReportGenerator.kt`: Routing and reefing suggestions based on wind/waves.
- `android-app/app/src/main/kotlin/org/terst/nav/tripreport/PreTripModels.kt`: Domain models for boat profiles and suggestions.
- `android-app/app/src/main/kotlin/org/terst/nav/tripreport/PreTripReportFragment.kt`: UI for generating and viewing pre-trip plans.

### [APPROVED] Enhanced Map & Track Visualization (2026-04-04)
- `android-app/app/src/main/kotlin/org/terst/nav/ui/MapHandler.kt`: `updateTrackLayer` now supports active and past tracks with distinct styles.
- `android-app/app/src/main/res/layout/activity_main.xml`: Refactored to vertical LinearLayout root to stabilize BottomNav and FAB placement.
- `android-app/app/src/main/res/layout/layout_instruments_sheet.xml`: Added "TRIP REPORTS & PLANNING" section for direct access from main view.
- `android-app/app/src/main/kotlin/org/terst/nav/MainActivity.kt`: Wired Pre-Trip and Trip Report buttons from instrument sheet; added `showReport` navigation helper.
- `android-app/app/src/main/kotlin/org/terst/nav/track/TrackRepository.kt`: Added `pastTracks` storage.
- `test-runner/src/main/kotlin/org/terst/nav/track/TrackRepository.kt`: Synchronized with main app implementation.

### [APPROVED] GpsPosition data class (2026-03-15)
- File: `app/src/main/kotlin/org/terst/nav/gps/GpsPosition.kt`
- Fields: latitude, longitude, sog (knots), cog (degrees true), timestampMs

### [APPROVED] DeviceGpsProvider (2026-03-15)
- Wraps `LocationManager` with `GPS_PROVIDER`
- Fix-lost timer: fires `onFixLost()` after 10s with no update

### [APPROVED] NmeaParser — RMC parser (2026-03-15)
- Parses any `*RMC` sentence (GP, GN, etc.)
- HHMMSS + DDMMYY → Unix epoch millis UTC

### [APPROVED] AIS Integration (2026-03-15)
- `AisVdmParser.kt`: Parses !AIVDM/!AIVDO (Types 1, 2, 3, 5).
- `AisRepository.kt`: Upserts vessels and merges static data.
- `AisHubSource.kt`: Integration with AISHub REST API.
- `MapFragment`: GeoJSON layer for AIS vessels with rotation and labels.

### [APPROVED] Track Recording (2026-03-25)
- `MainViewModel`: TrackRepository wired; `addGpsPoint` enriches with environmental data.
- `MainActivity`: FAB for toggling recording; MapHandler for rendering.

## Next 3 Specific Steps
1. **Unit Tests for Trip Generators** — Add JVM tests in `test-runner` for `TripReportGenerator` and `PreTripReportGenerator`.
2. **Persist track to Room** — Replace in-memory `pastTracks` with a Room database for persistence across sessions.
3. **AnchorWatchHandler UI** — Re-integrate `AnchorWatchHandler` UI into `activity_main.xml` and wire it to the Safety Dashboard.

## Scripts Added
- `test-runner/` — standalone Kotlin/JVM Gradle project for fast test cycles.

## Process Improvements
- Stabilized UI layout by moving navigation out of the `CoordinatorLayout`.
- Duplicated core logic into `test-runner` to bypass Android SDK requirements for logic testing.
