A marked day is a UTC day the feed listed this address. The feed keeps a listener for up to 90 days after its last confirmation, so a listed day is not a confirmation. A listener no longer in the feed is drawn to its last confirmation.

The hash of the file this listener served when scanned. A host can change what it serves. Only the response’s Content-Type claimed a download; no executable magic bytes were seen, so the file type is unverified.
