Description, as the server wrote it:

```untrusted-server-text
Deterministic acceptance report for a supplied product catalog: validates price/currency/availability/URL formatting, GS1 GTIN checksums, and flags duplicate SKUs, duplicate GTINs, and grouped-variant collisions. Checks only the structured rows given in the request - no network calls, no brand or marketplace certification, no ISO 4217 currency list. Price: 0.05 USDC per completed bounded job on Base.
