Does this guarantee Google approval?
No. FeedGuard is a deterministic preflight for file-level mistakes. Google also checks policies, account configuration, websites, crawlability, and consistency with landing pages.
Is my feed uploaded?
No. Parsing and validation run locally in your browser. Only a transaction hash is sent to the public Base RPC when you request payment verification.
Why Base USDC?
It allows permissionless, auditable settlement without collecting names, emails, card data, or passwords.
What does the paid export include?
One record per finding with source row, field, severity, stable issue code, recommendation, and a truncated source value.
