feat(instruments): add forecast wind, wave, swell and current from Open-Meteo

2026-04-03T07:38:22+00:00

- Add swell params to MarineApiService request - Add swell fields to MarineHourly model - Add MarineConditions snapshot model - Add WeatherRepository.fetchCurrentConditions() (first forecast hour) - Add MainViewModel.loadConditions() + marineConditions StateFlow - Add Forecast section to instrument sheet: Curr / Wave / Swell - Populate TWS from forecast wind speed on first GPS fix - Trigger loadConditions() once on first GPS position received Co-Authored-By: Claude Sonnet 4.6

feat: satellite GRIB download with bandwidth optimisation (§9.1)

2026-03-25T04:55:20+00:00

Implements weather data download over Iridium satellite links: - GribParameter enum with SATELLITE_MINIMAL set (wind + pressure only) - SatelliteDownloadRequest data class (region, params, forecast hours, resolution) - SatelliteGribDownloader: size/time estimation, abort-on-oversized, pluggable fetcher - 8 unit tests covering estimation scaling, minimal param set, and download outcomes Co-Authored-By: Claude Sonnet 4.6

feat: offline GRIB staleness checker, ViewModel integration, and UI badge

2026-03-25T04:55:10+00:00

- Add GribRegion, GribFile data models and GribFileManager interface - Add InMemoryGribFileManager for testing and default use - Add GribStalenessChecker with FreshnessResult sealed class (Fresh/Stale/NoData) - Integrate weatherStaleness StateFlow into MainViewModel (checked after loadWeather) - Add yellow staleness banner TextView to fragment_map.xml - Wire staleness banner in MapFragment (shown on Stale, hidden on Fresh/NoData) - Add GribStalenessCheckerTest (4 TDD tests) Co-Authored-By: Claude Sonnet 4.6

2026-03-25T04:54:58+00:00

- LogbookEntry data class: timestampMs, lat/lon, SOG, COG, wind, baro, depth, event/notes - LogbookFormatter: UTC time, position (deg/dec-min), 16-pt compass, row/page builders - LogbookPdfExporter: landscape A4 PDF via android.graphics.pdf.PdfDocument with column headers, alternating row shading, and table border - 20 unit tests covering all formatting helpers and data model behaviour Co-Authored-By: Claude Sonnet 4.6

feat: implement isochrone-based weather routing (Section 3.4)

2026-03-25T04:54:49+00:00

feat: add harmonic tide height predictions (Section 3.2 / 4.2)

2026-03-25T04:54:31+00:00

Implement offline harmonic tide prediction as specified in COMPONENT_DESIGN.md: - TideConstituent: name, speedDegPerHour, amplitudeMeters, phaseDeg - TidePrediction: timestampMs, heightMeters - TideStation: id, name, lat, lon, datumOffsetMeters, constituents - HarmonicTideCalculator: predictHeight(), predictRange(), findHighLow() Formula: h(t) = Z0 + Σ [ Hi × cos( ωi × (t − t0) − φi ) ] - 15 unit tests covering all calculation paths Co-Authored-By: Claude Sonnet 4.6

feat: add GribFileManager interface and InMemoryGribFileManager

2026-03-16T00:45:04+00:00

feat: add GribRegion and GribFile data models with staleness logic

2026-03-16T00:02:55+00:00

fix: move weather feature to org/terst/nav package directories

2026-03-15T06:52:23+00:00

Package declarations were already org.terst.nav.* but files lived under com/example/androidapp/. Kotlin 2.0 (K2) compiler on CI fails when package declarations don't match directory structure during kapt stub generation. Moved all 20 files to their correct locations and renamed MainActivity (weather) -> WeatherActivity to avoid confusion with the nav app's MainActivity. Co-Authored-By: Claude Sonnet 4.6
