A history that breaks visibly if anyone touches it.
An append-only event log runs across all branches, with per-entity chains and daily checkpoints. The integrity of the record does not rest on trust in an operator — it rests on math.
- Hash-chained audit spine: any alteration of history breaks every subsequent hash.
- OpenTimestamps anchoring (optional): daily checkpoints anchored to the Bitcoin blockchain — existence proofs verifiable by anyone, forever.
- Litigation-ready exports: chain-verification reports and per-record integrity proofs in formats a court can consume.
