Function: useWayfinding()
useWayfinding(
graph,obstacles?,activeFloorId?):UseWayfindingResult
Defined in: packages/ui/src/useWayfinding.ts:166
useWayfinding(graph, obstacles?, activeFloorId?) — pure routing logic with no map dependency.
Returns { setStart, setStop, path, startCoord, stopCoord, reset }. path is a GeoJSON LineString Feature or null. Obstacles are pre-processed at hook initialisation time (not per route call).
activeFloorId (issue #460), when provided, restricts setStart/setStop snapping to nodes on that floor (and vertical-transport nodes are always excluded regardless) — otherwise a tap can silently snap onto a different floor's node that happens to be geometrically closer.
