Known caveats

Mobile coverage is still served at area level in the public seam, so treat it as a shortlist signal rather than a street-level verdict.
Connectivity rows do not replace a final provider and address-level availability check before you commit to a property.
If you search a postcode area, neighbouring postcode rows can differ enough that the exact postcode follow-up still matters.
