Honda/Acura Dealer Coverage — Review Needed

Honda dealer collection (ai_public_api/honda/dealer_api.py) fans out over the shared ai_core.geo.US_NATIONAL_ZIP_SWEEP constant — the same hardcoded 58-zip list used by GM and JLR — at ~250-mile radius with a maxResults=500 per-call cap.

A hands-on review of GM's use of this same sweep (at 100mi) found major coverage gaps — only 62.4% of continental-US ZIP centroids within radius, plus three invalid/hallucinated zips that silently returned nothing. See GM Dealer Source for the full analysis and the general Verification procedure.

The three fake zips have been corrected in ai_core.geo (they affected Honda too). Honda's 250mi radius is far more forgiving than GM's 100mi, so coverage is likely much better — but this has not been measured.
