Probe 22 points with the USGS 3DEP point service: walkable surfaces span 115.65-119.59 m, a 3.94 m relief, so elevation data is required by the AGENTS rule. Grade falls ~3.3 m eastward over the 279 m block (1.2%) and the north sidewalk sits 0.4-0.7 m above the south. 3DEP 1 m is public domain and becomes the chosen source; the tile itself is still to be downloaded. Factored the shared OSM helpers into Geo/scripts/osm_common.py so the street profile and the elevation probe read the same geometry.
