invinoveritas /x402/seller-intel — recomputable x402 BUYER intelligence + a verdict on why you're buried: pass a {wallet} for its on-chain behavior (catalog-walker vs real-customer verdict, spend, the sellers winning its money), or your {domain} for a DISCOVERABILITY audit (catalog offset + the daily-crawl mechanics).
