How the engine got there

Waiting for a question.

Concept demo. Places come from OpenStreetMap (Nominatim, Overpass, Photon). The @ Code arithmetic is exact and needs no lookup table. The choices between candidates (which Eiffel Tower, which McDonald’s) use fixed context rules here, where the production engine would use an AI model that treats @ Codes as a new kind of precise location token. A code such as @3881 repeats every 1 km, nn@nnnn every 10 km and nnnn@nnnn every 100 km; the place name and the map view say which one.
