Field notes
The demonstration uses a source record labeled CAL-2026-03 at version 3 and a receipt for segment 2 of 4. A visitor can edit the figure 0.0412, watch the content digest and Merkle root stop matching the signed receipt, then restore the record. The page also separates mechanism from trust: its constants are controlled by the page operator, while real deployments would use externally configured keys and a log root held by an independent party.
