    Summary for a host (no time series): first/last seen, current verdict mix, n_resources, total verdict changes, gone_since if absent from the latest full scan, and a small resources_sample. Sample rows with in_latest_scan=false were not in the latest full scan; read last_checked_at for when they were last probed. n_resources counts every resource ever seen for this host; current_verdict_mix and n_payable_last_full count only the latest full scan. last_checked_at is the last time any scan looked at the resource; verdict_since is when the current verdict was first observed in the unbroken run that leads to it. A scan that did not contain the resource does not break the run, so verdict_since can span weeks nobody measured. How current a row is comes from last_checked_at and in_latest_scan, not from verdict_since alone.

reportsread-onlyPublished weekly payability reports (from the signed manifest).
verify_signatureread-onlyOffline EIP-191 verify of a signed nsgoods response. Identifies the service from the manifest (or the optional `service` arg), strips exactly that service's post-sign fields, canonicalises (JCS, both ASCII modes), recovers the signer and checks it against the published manifest signers. Reproduction-attestation (JCS/byte-length) and envelope (signer/signature, components) shapes are reported as unsupported_shape, not verified here. Refusals carry a distinct status: malformed_signature (signature is not a 65-byte 0x-prefixed hex string), schema_rejected (the body carries a signed_by/signature pair but fails the required field shape for every service the claimed signer covers; recovery was not attempted, checked is false, reasons lists the failed candidates), signature_mismatch (well-formed but recovers a different address than signed_by under every candidate service recipe of this signer), no_flat_recipe (signed_by is a manifest signer but every service it covers uses an envelope shape, so there is no flat recipe to check; recovery was not attempted, checked is false), unknown_signer (signed_by is not a manifest signer; recovery was not attempted, checked is false), unsupported_shape, or the no-signed_by/signature-pair case. checked is true only when EIP-191 recovery actually ran; every other refusal reports checked false.
x401_statusread-onlyCurrent x401 emitter adoption across the scanned catalogue (from the daily watcher).
