Tech debt: delete com.example.androidapp ghost package, symlink TackDetector, fix forecast current hour

2026-05-28T07:09:43+00:00

- Deleted all 18 stale source files in com.example.androidapp (main + test) that duplicated org.terst.nav implementations from an earlier namespace - Fixed the 3 tide model files (TidePrediction/Station/Constituent) whose package declarations read com.example.androidapp.data.model despite living in org.terst.nav.data.model directories - Fixed HarmonicTideCalculator.kt imports to match the corrected package - Fixed TideModelTest.kt package declaration - Migrated HarmonicTideCalculatorTest to org.terst.nav.tide with correct imports - Replaced test-runner's TackDetector.kt copy with a symlink to the android-app canonical source so the two can never diverge again - Fixed addGpsPoint to pick the current wall-clock hour's forecast slot instead of always using the app-start hour (first item in forecast list) https://claude.ai/code/session_01KXYBuAHZkvv63DeUG6XaZD

Fix ANR, false tack detections, and empty-state flash on track load

2026-05-26T07:46:09+00:00

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. https://claude.ai/code/session_01KXYBuAHZkvv63DeUG6XaZD

Redesign tack detection: time-based windows + circularMAD stability

2026-05-26T06:39:05+00:00

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). https://claude.ai/code/session_01YUbuZNDAoLea4cf9UGQ9qn

Fix Long overflow in TackDetector: var lastTackMs = Long.MIN_VALUE caused subtraction overflow, filtering every tack

Add saved tracks browser, tack detection, and map zoom-to-bounds

2026-05-12T23:13:55+00:00

- 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 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 Co-Authored-By: Claude Sonnet 4.6

Merge origin/main — unite all work onto one branch

2026-04-23T23:10:11+00:00

Brings in dev log (NavLogger), UnitPrefs, MapLayerManager, HUD views, conditions throttling, track save/load pipeline, improved ParticleWindView (antimeridian-aware, dynamic particle count), Snackbar error surfacing, and all other main-branch work from the prior session. Combined with master's hardware source flags, vessel registry, crew management, thermal alarm, CPA collision alerts, and track stats. Also documents primary branch policy in CLAUDE.md and .agent/config.md: all work merges to main, never master. https://claude.ai/code/session_011h2dXbgXg3PesQMmQUNTCW
