fix+feat: CI build fixes and hardware source feature flags

2026-04-22T09:02:46+00:00

CI fixes: - ParticleWindView: bounds.lonEast → bounds.northEast.longitude (MapLibre 13.x API; lonEast not available as property) - VesselRegistryFragment: Vessel(id="") and CrewMember(id="") → include required name="" so copy() compiles Hardware source feature flags: - HardwareSource enum: AIS_RECEIVER, NMEA_INSTRUMENTS - FeatureFlags: SharedPreferences-backed; all sources default OFF (app works phone-only out of the box) - NavApplication: exposes featureFlags singleton - SafetyFragment: "HARDWARE DATA SOURCES" card with two MaterialSwitch toggles; reads initial state from FeatureFlags; calls SafetyListener.onHardwareSourceChanged on change - AIS_RECEIVER flag: - MainViewModel.processAisSentence() / refreshAisFromInternet() skip when disabled; onHardwareSourceChanged() clears targets + cpaAlerts - NMEA_INSTRUMENTS flag: - LocationService skips nmeaStreamManager.start() on service launch when disabled - New ACTION_START_NMEA / ACTION_STOP_NMEA intents allow live toggle - MainActivity.onHardwareSourceChanged() sends the appropriate intent Tests: 102 total, all GREEN (+7 FeatureFlagsTest) https://claude.ai/code/session_011h2dXbgXg3PesQMmQUNTCW

feat: CPA/TCPA collision alerts and live track stats

2026-04-22T08:45:55+00:00

CPA/TCPA alerts: - CpaAlert data class with severity (CAUTION/WARNING/DANGER) and label() - CpaThresholds: 0.5/1.0/2.0 nm, max TCPA 30 min - MainViewModel.updateCpaAlerts() runs on every GPS update and AIS sentence; skips stationary contacts; filters TCPA ≤ 0 or > 30 min; sorts by TCPA ascending - SafetyFragment: new COLLISION AVOIDANCE card shows live alert list, color-coded by severity; clears to "No traffic alerts" when safe - MainActivity: observes cpaAlerts → safetyFragment.updateCpaAlerts() Track stats: - TrackStats data class: distanceNm, durationMs, avgSogKnots, durationFormatted (m:ss / h:mm:ss) - TrackRepository.haversineNm() + computeStats() using point timestamps - MainViewModel exposes trackStats StateFlow, cleared on stopTrack() - activity_main: dark pill overlay bar (tv_track_stats) above map - MainActivity: shows "● REC 0.00nm m:ss x.xkt avg" while recording Tests: 95 total, all GREEN (+16 new — 9 TrackStats, 7 CpaAlert) https://claude.ai/code/session_011h2dXbgXg3PesQMmQUNTCW

feat: integrate AIS into ViewModel and MapFragment with vessel symbol layer

2026-03-15T14:20:21+00:00

- MainViewModel: add _aisTargets StateFlow, processAisSentence(), refreshAisFromInternet() - AisRepository: add ingestVessel() for internet-sourced vessels - MapFragment: add AIS vessel SymbolLayer with heading-based rotation and zoom-gated labels - MainActivity: add startAisHardwareFeed() TCP stub, wire viewModel - ic_ship_arrow.xml: new vector drawable for AIS target icons - MainViewModelTest: 3 new AIS tests (processAisSentence happy path, dedup, non-AIS sentence) - JVM test harness: /tmp/ais-vm-test-runner/ — 3 tests GREEN Co-Authored-By: Claude Sonnet 4.6

feat: add AIS repository, AISHub API service, and AisHubSource

2026-03-15T13:13:34+00:00

- AisRepository: processes NMEA sentences, upserts by MMSI, merges type-5 static data, evicts stale - AisHubApiService + AisHubVessel: Retrofit/Moshi model for AISHub REST polling API - AisHubSource: converts AisHubVessel REST responses to AisVessel domain objects - 11 JUnit 5 tests all GREEN via /tmp/ais-repo-test-runner/ JVM harness Co-Authored-By: Claude Sonnet 4.6

feat: add AIS data model, CPA calculator, and NMEA VDM parser

2026-03-15T12:24:35+00:00

- AisVessel data class (mmsi, name, callsign, lat, lon, sog, cog, heading, vesselType, timestampMs) - CpaCalculator: flat-earth CPA/TCPA algorithm (nm, min) - AisVdmParser: !AIVDM/!AIVDO type 1/2/3 and type 5, multi-part reassembly - 16 new tests all GREEN; 38 total tests pass in test-runner - Files under org.terst.nav.ais/nmea (com dir was root-owned) Co-Authored-By: Claude Sonnet 4.6
