- osm-dump.mjs: capture way name/ref as edgeNames; honor oneway & roundabout as directed edges; graphHighways widened to include named local roads
- routing.ts: buildTurnInstructions emits 'Head north on Pine St' / 'Turn right onto 21st St'; merges short legs to avoid phantom turns; nameResolverFor() maps node path to street names
- Rebuilt tulsa-dump-graph.json: 225,956 nodes / 227,468 edges (was 55k); ~27MB (was 4.7MB)
- tests, README updated
- scripts/osm-dump.mjs: download & stream-parse regional .osm.pbf extracts
(Geofabrik/BBBike etc). Clips to bbox, extracts POI features (poiTags),
and builds a routable road graph (coords + weighted adj) from road ways.
Caches the downloaded .pbf under scripts/.cache/ (git-ignored). Default:
Geofabrik Oklahoma extract -> tulsa-dump layer (12.8k POIs, 55k-node graph).
- src/lib/routing.ts: client-side A* routing over the graph. Snaps A/B to
nearest nodes, supports avoid-rules (category + radius, block or penalty)
built from nearby POIs; returns waypoints + distance.
- src/lib/components/DirectionsPanel.svelte: Directions UI — pick A/B by
clicking the map, choose POI categories to avoid, compute & draw the route.
- MapView: adds a Directions toggle when a dump layer with a graph is present.
- package.json: add 'build:dump'; build now runs data + dump + static.
- scripts/test.mjs: validate dump manifest entries + routing graph structure.
- README: document dump ingestion and the routing/avoid feature.
