Is it address from Wikidata? Geolocated based on position?

[matkoniecz]

In Warszawa there are hundreds of matches of protected buildings and I am not sure should I use that address for confirming matches

Is it stated in Wikidata (useful for confirming matches when address is in OSM tags)?

Is it geolocated based on position (requires checking Wikidata for each entry)?

Is it from OSM tags of found match (then useless for confirming matches)?

I think you figured it out since 2021, but is stated in Wikidata P6375
If P6375 and the addr:= tags are the same and P625 (coordinates) and OSM coordinates are the same, I would consider it a sure match.
