Every event above carries a SHA-256 hash of its structured payload. Hashes are rolled into a daily Merkle tree; the root is recorded in a signed anchor batch and (when the operator opts in) anchored on a public ledger like XRPL or Xahau. Tampering with a stored event invalidates its proof. The Anchored mark on each event reflects this; anyone can independently check the signature, revocation status, and Merkle proof against the downloadable credential at Verify independently. https://app.rovify.io/verify/ATH-2026-0006
