Every score aggregates only feedback whose submitter proved a settled on-chain USDC payment to that merchant (at least the published floor) and signed with the paying wallet, so no row is free and wash patterns are exposed by independence signals.

One live probe of a public URL against your expectation (HTTP status, keyword, CSS selector, JSON path), answered synchronously as an Ed25519 signed verdict that embeds a signed observation: final URL, resolved address, TLS certificate fingerprint, response headers, raw body sha256, timestamp.
