  "how_to_check": "Fold leaf into root by hashing it against each path entry in order, left sibling first when side is left. Then verify ots_base64 (or the file at ots_url) against a Bitcoin node with any OpenTimestamps client: it commits to root. Neither step needs crawlcheck.io to be online, or honest."
