The proof
Verify the book
Every create, edit, decision, delete and stamped settlement is sealed into a per-line chain of SHA-384 digests. This page recomputes all of them and, if anything no longer matches, names the exact event that changed.
Replay
Walking the chains…
Recomputing every digest…
Try to break it
The replay is deterministic and has unit tests pinned to hand-computed digests, so the check is reproducible rather than merely green. If you want to see a chain fail, edit a row directly in Postgres and reload this page: the seal stops matching and the page names the exact event that changed.
