+NOTE: this scan is a crude keyword heuristic, NOT a verified finding. On-chain
+identifiers (transaction hashes, EAS attestation and schema UIDs, block and
+deliverable hashes, hex-encoded strings) share the shape of a private key and are the
+normal, expected content of this repo. Before mentioning a hit at all, look at the
