Geocoding uncertainty
Address-to-point geocoding carries a precision tier (rooftop, street, ZIP centroid) that is often dropped downstream; a ZIP-centroid-precision point treated as rooftop-precision misassigns the cell.

Detection
Geocoder confidence/precision field below rooftop/parcel tier.
02
Mitigation
01
Carry the geocoder precision tier through the pipeline
02
Cap effective H3 resolution to match the geocode precision tier, never index finer than the input warrants
