Does this noexit actually connect to the other foot path? It seems like it might, but I haven't walked there, and can't tell from satellite.

These buildings' borders are incorrect. They are "tagged for the renderer" osm.wiki/Tagging_for_the_renderer so they look good in 3D, but the building numbers do not line up with semantic reality.

These should be rearranged to correspond to the actual buildings, with "building:part" used for the cute 3D stuff.

Unable to answer "Do these steps have a ramp? What kind?" for osm.org/way/41178687 via StreetComplete 43.1:

Wheelchair ramp is a separate way, but which does not exist on the map. It's the short asphalt way.
