Checks 1–7

A validity layer for ERC-8004 reputation on Celo. Provenance verifies whether a feedback record's declared evidence file and declared payment hold up — the file fetched and hashed, the transaction read from the chain it names — and publishes the verdict as an on-chain attestation, two dimensions per record. It scores nothing and ranks nothing: it is the input other scorers, marketplaces and routers read to weight feedback by something harder than assertion. Measured on 2026-08-31 across 27,538 registry records: 111 payment claims, of which 0 were verified and attributed to their declared parties and 93 name transactions that do not exist on the chain they name. 10,486 verdicts are on chain under two contiguous coverage claims that publish what the indexer observed beside what the attester wrote, so the attester's own silence is checkable.

A declared endpoint responds to a probe. Not implemented yet, so nobody passes or fails it.

outside the census

Everything above is one sweep, pinned to one block. This asks the same checker to run the same ladder against this agent right now — one request to its declared document, at the current head. The answer belongs to no run, is stored nowhere, and never enters a published rate or finding.
