Note Paper-era artifact. Stage 1 crop model, rounds 1 and 2: converts government curb ramp GPS coordinates into pixel keypoints. Stage 1 cannot be reproduced without round 2.

Note Paper-era artifact. The government inventories the paper actually ran on, the street centrelines, and the manifests recording exactly which panoramas Stage 1 consumed.

Note POST-PUBLICATION, not part of the paper. 9 city splits built in 2026 to test the published model out of domain (non-US cities, Mapillary imagery) and against VLM detectors. The paper evaluated on a 1,000-panorama gold set from its three training cities, so numbers measured here are not comparable with the published ones.
