Environmental Conditions feature:
- C++ EnvironmentTimeline: time-series current/wind data, JSON serialization
- WASM bindings: loadEnvironment(), World integration
- TypeScript types: CurrentSeries, WindSeries, EnvironmentPayload
- Zustand environmentStore with React panel (EnvironmentConditionPanel)
- Mock WASM current drift physics: nautical→body-frame velocity applied in step()
Bug fixes:
- Vessel instanceId: unique auto-increment ID per scenario instance prevents duplicate
vesselId crash when adding two vessels of same type
- vesselPanelStore: separate vesselTypeId field so config fetch uses correct type ID
(not instanceId) after the instanceId/vesselId split
- VesselMarker stable eventHandlers: useMemo + useRef pattern prevents react-leaflet
from re-registering Leaflet listeners every 50ms tick, fixing panel clicks during
active simulation
Tests:
- Playwright regression suite (e2e/regression.spec.ts): 8 tests covering panel open
during simulation, multi-click consistency, two VLCC no error, dual marker render,
individual panel open, remove-one behavior, current drift, no-drift baseline
