Introduces TackMode enum (CRUISING/RACE) and per-mode Config, replacing
the previous single set of hardcoded constants.
RACE config: T_SETTLE=12s, T_MANEUVER=20s, STAB_MAX=30°, MIN_GAP=20s,
START_SKIP=20s — tighter windows for quick successive tacks at race
starts and mark roundings. CRUISING remains the default.
Two new tests demonstrate the behavioral difference: RACE fires earlier
(past 20s cold-start vs 60s) and keeps separate events for a 50s gap
that CRUISING deduplicates (50s < 60s MIN_GAP). 18/18 passing.

ANR: getSavedTracks() had no IO dispatcher — TackDetector ran on main
thread at O(n²) cost (~77M ops for a 2.5h track). Added withContext(IO).
TackDetector: replaced O(n) list.filter with O(log n) binary-search
subList for before/after windows; O(n²) → O(n log n). Raised MIN_DELTA
60°→75° to stop detecting ordinary course corrections as maneuvers.
Removed MAX_DELTA cap entirely — 180° crash-tacks are valid; the
circularMAD stability windows are the real quality gate.
TrackDetailSheet: dropped the arbitrary abs(delta)>70 Tack/Jibe
heuristic. Now uses true wind angle when available for classification;
falls back to "Maneuver" when TWD is absent.
SavedTracksFragment: added isLoadingTracks StateFlow (MainViewModel);
combine() suppresses the empty-state layout while the initial IO load
runs so it no longer flashes "No saved tracks yet" before data arrives.
16/16 TackDetector tests pass.

Replace the point-count window (HALF_WIN=2) with 30s time-based settle
windows that give consistent reliability regardless of GPS update rate
(1 Hz FULL vs 0.2 Hz ECONOMY). Key changes:
- Before/after windows are time-based (T_SETTLE=30s) around a guard
zone (T_MANEUVER=30s), not point counts.
- Stability uses circularMAD (<20°) across all fixes in each window,
replacing the single-pair spread check. This correctly handles
0°/360° wrap and suppresses random anchor-watch COG noise (MAD≈90°).
- No SOG gate: averaging 30 fixes over 30s reduces noise by √30
regardless of boat speed. A boat at anchor has MAD≈90° and is
rejected by the stability check.
- MAX_DELTA raised to 160° (covers deep jibes the old 140° missed).
- START_SKIP reduced to 60s (stability check handles cold-start noise).
- De-duplication uses adjacent-candidate comparison so a long stream
of raw candidates from one maneuver stays in a single group even if
it spans >MIN_GAP_MS in total.
- Position refined to max instantaneous heading rate within the
maneuver zone.
- Mode: CRUISING (conservative). Race mode noted as future backlog.
16/16 unit tests pass at 1 Hz (FULL mode GPS rate).

- TackDetector: sliding-window COG algorithm (60-140deg delta = tack/jibe)
with stability check to prevent mixed-window false positives; 13 tests green
- TackEvent, SavedTrack: new models wrapping points + summary + detected tacks
- TrackRepository.getSavedTracks(): returns List<SavedTrack> with lazy load
- MapHandler: zoomToTrackBounds (LatLngBounds fit with padding),
panToPoint (log step-through), updateTackLayer (yellow circle markers)
- MainViewModel: savedTracks + selectedTrack StateFlows, panToPosition SharedFlow
- SavedTracksFragment: RecyclerView list with date/distance/duration/tack count
- TrackDetailSheet: bottom sheet with stats + event log (tacks, speed changes,
start/end); tapping an entry pans the map to that position
- MainActivity: zoom map on track complete, wire Saved Tracks button in
instrument sheet, observe panToPosition to drive map, show tack markers
when a saved track is selected

* feat: add AnchorWatchHandler UI with Depth/Rode Out inputs and suggested radius
- Add AnchorWatchState with calculateRecommendedWatchCircleRadius, which
uses ScopeCalculator.watchCircleRadius (Pythagorean scope formula) and
falls back to rode length when geometry is invalid
- Add AnchorWatchHandler Fragment with EditText inputs for Depth (m) and
Rode Out (m); updates suggested watch circle radius live via TextWatcher
- Add fragment_anchor_watch.xml layout
- Wire AnchorWatchHandler into bottom navigation (MainActivity + menu)
- Add AnchorWatchStateTest covering valid geometry, short-rode fallback

* feat(safety): log wind and current conditions at MOB activation (Section 4.6)
Per COMPONENT_DESIGN.md Section 4.6, the MOB navigation view must display
wind and current conditions at the time of the event.
- MobEvent: add nullable windSpeedKt, windDirectionDeg, currentSpeedKt,
currentDirectionDeg fields captured at the exact moment of activation
- MobAlarmManager.activate(): accept optional wind/current params and
forward them into MobEvent (defaults to null for backward compatibility)
- LocationService (new): aggregates live SensorData (resolves true wind via
TrueWindCalculator) and marine-forecast current conditions; snapshot()
provides a point-in-time EnvironmentalSnapshot for safety-critical logging
- MobAlarmManagerTest: add tests for wind/current storage and null defaults
- LocationServiceTest (new): covers snapshot, true-wind resolution,
current-condition updates, and the latestSensor flow

* feat(gps): implement NMEA/Android GPS sensor fusion in LocationService
Adds priority-based selection between NMEA GPS (dedicated marine GPS,
higher priority) and Android system GPS (fallback) within LocationService.
Selection policy:
1. Prefer NMEA when its most recent fix is fresh (≤ nmeaStalenessThresholdMs, default 5 s)
2. Fall back to Android GPS when NMEA is stale
3. Use stale NMEA only when Android has never reported a fix
4. bestPosition is null until at least one source reports
New public API:
- GpsSource enum (NONE, NMEA, ANDROID)
- LocationService.updateNmeaGps(GpsPosition)
- LocationService.updateAndroidGps(GpsPosition)
- LocationService.bestPosition: StateFlow<GpsPosition?>
- LocationService.activeGpsSource: StateFlow<GpsSource>
- Injectable clockMs parameter for deterministic unit tests
Adds 7 unit tests covering: no-data state, fresh NMEA priority,
stale NMEA fallback, only-NMEA/only-Android scenarios, exact-threshold
edge case, and NMEA recovery after Android takeover.

* feat(gps): add fix-quality (accuracy) tier to GPS sensor fusion
Extend LocationService's source-selection policy with a quality-aware
"marginal staleness" zone between the primary and a new extended
staleness threshold (default 10 s):
1. Fresh NMEA (≤ primary threshold, 5 s) → always prefer NMEA
2. Marginally stale NMEA (5–10 s) → prefer NMEA only when
GpsPosition.accuracyMeters is strictly better than Android's;
fall back to Android conservatively when accuracy data is absent
3. Very stale NMEA (> 10 s) → always prefer Android
4. Only one source available → use it regardless of age
Changes:
- GpsPosition: add nullable accuracyMeters field (default null, no
breaking change to existing callers)
- LocationService: add nmeaExtendedThresholdMs constructor parameter;
recomputeBestPosition() now implements three-tier logic; extract
GpsPosition.hasStrictlyBetterAccuracyThan() helper
- LocationServiceTest: expose nmeaExtendedThresholdMs in fusionService
helper; add posWithAccuracy helper; add 4 new test cases covering
accuracy-based NMEA preference, worse-accuracy fallback, no-accuracy
conservative fallback, and very-stale unconditional fallback

* chore: add .gitignore, pull-crash-logs script, updated agent permissions
- .gitignore: exclude agent artifacts (.claudomator-env, .agent-home/, crash-logs/)
- scripts/pull-crash-logs: download Crashlytics crash reports via Firebase CLI
- .claude/settings.local.json: add Android SDK/emulator/adb permission rules

* chore: update CI workflow to target main branch
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix: resolve all Kotlin compilation errors blocking CI build
- Migrate kapt → KSP (Kotlin 2.0 + kapt is broken; KSP is the supported path)
- Fix duplicate onResume() override in MainActivity
- Fix wrong package imports: com.example.androidapp.data.model → org.terst.nav.data.model
across GribFileManager, GribStalenessChecker, SatelliteGribDownloader,
LogbookFormatter, LogbookPdfExporter, IsochroneRouter, AnchorWatchHandler
- Create missing SensorData, ApparentWind, TrueWindData, TrueWindCalculator classes
- Inline missing ScopeCalculator formula (Pythagorean) in AnchorWatchState

* feat(track): implement GPS track recording with map overlay
- TrackRepository + TrackPoint wired into MainViewModel:
isRecording/trackPoints StateFlows, startTrack/stopTrack/addGpsPoint
- MapHandler.updateTrackLayer(): lazily initialises a red LineLayer
and updates GeoJSON polyline from List<TrackPoint>
- fab_record_track FAB in activity_main.xml (top|end of bottom nav);
icon toggles between ic_track_record and ic_close while recording
- MainActivity feeds every GPS fix into viewModel.addGpsPoint() and
observes trackPoints to redraw the polyline in real time
- ic_track_record.xml vector drawable (red record dot)
- 8 TrackRepositoryTest tests all GREEN

* test(ci): share APKs between jobs and expand smoke tests
CI — build job now uploads both APKs as the 'test-apks' artifact.
smoke-test job downloads them and passes -x assembleDebug
-x assembleDebugAndroidTest to skip recompilation (~4 min saved).
Test results uploaded as 'smoke-test-results' artifact on every run.
Smoke tests expanded from 1 → 11 tests covering:
- MainActivity launches without crash
- All 4 bottom-nav tabs are displayed
- Safety tab: Safety Dashboard, ACTIVATE MOB, ANCHOR WATCH visible
- Log tab: voice-log mic FAB visible
- Instruments tab: bottom sheet displayed
- Map tab: returns from overlay, mapView visible
- MOB FAB: always visible, visible on Safety tab
- Record Track FAB: displayed, toggles to Stop Recording, toggles back
MainActivity: moved isRecording observer to initializeUI() so the
FAB content description updates without requiring GPS permission
(needed for emulator tests that run without location permission).
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* refactor: address simplify review findings
TrackRepository.addPoint() now returns Boolean (true if point was
added). MainViewModel.addGpsPoint() only updates _trackPoints StateFlow
when a point is actually appended — eliminates ~3,600 no-op flow
emissions per hour when not recording.
MainActivity: loadedStyle promoted from nullable field to
MutableStateFlow<Style?>; trackPoints observer uses filterNotNull +
combine so no track points are silently dropped if the style loads
after the first GPS fix.
Smoke tests: replaced 11× ActivityScenario.launch().use{} with a
single @get:Rule ActivityScenarioRule — same isolation, less
boilerplate.
CI: removed redundant app-debug artifact upload (app-debug.apk is
already included inside the test-apks artifact).
Removed stale/placeholder comments from MainActivity.

* fix(ui): anchor record track FAB to instrument sheet to prevent it being hidden
The FAB was anchored to bottom_navigation, placing it in the peek zone
of the instrument bottom sheet (120dp) and making it invisible to users.
Re-anchoring to instrument_bottom_sheet keeps the button visible and
makes it track naturally with sheet drag gestures.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix(ui): anchor MOB FAB to instrument sheet to match record-track FAB
The fab_mob was still anchored to bottom_navigation using the same
top|start pattern that caused fab_record_track to be hidden behind
the instrument sheet's 16dp elevation. Apply the same fix so the
safety-critical MOB button is not occluded.
