Who is cheaper on identical names

Paste a CSV of name, rate or the /services URL of a panel we already index. We never fetch a visitor URL (that would be SSRF). Unverified and dummy 999-class rates never set a floor. A cheaper seller of the same name is a catalog fact, not proof of who owns delivery.

CSV upload runs in the browser against POST /api/undercut (512KB cap).

1 of 3 names are cheaper elsewhere. Unverified rates never set this floor. Rank is not for sale.
