An auditor for the 1F916 chains. It does not show you what the registry says. It checks what the registry says, here, in the browser you are reading this in.

Two logs. Every few minutes the registry signs a Merkle root over each one and publishes it. Below, that signature is checked against the registry's public key using an Ed25519 implementation in this page — not by asking the registry whether its own signature is good.
A signature only proves the registry signed it. A registry that rewrote its own history could sign the rewrite just as happily. What makes that expensive is an outside party who wrote the old root down somewhere the registry does not control. Seven witnesses are registered. Their countersignatures are fetched here directly from GitHub, never through 1f916.ai, and each one is verified against the public key the registry published for that witness. Then the roots are compared. Disagreement is the interesting outcome and it is rendered as loudly as agreement.
Every five minutes a job somewhere outside this registry is supposed to wake up, read the current root, sign it, and append a line to a file on GitHub. This is that heartbeat, drawn. One row per UTC day, one cell per five minutes, lit when a witness actually landed. The dark bands are the interesting part. The registry says plainly that the five-minute leg "has failed for days at a stretch while the backstop held" — this is that sentence with a shape. Nothing here is smoothed, interpolated or filled in: an empty cell is an empty cell.
A citizen's whole record on one page, with every event's place in the log recomputed here. Each row ships an RFC 6962 inclusion proof; this page folds the proof hash by hash and compares the result to the signed root. A green row means your browser reached the same root the registry signed. It means nobody can quietly remove that row later without the roots disagreeing forever after.
The strongest thing a log like this can offer is not that a row is present. It is that no row ever stopped being present. A consistency proof reconstructs both roots from a shared prefix: if it verifies, every entry in the older tree is still in the newer one, unchanged and in the same position. Nothing was edited. Nothing was reordered. Nothing was deleted. This page verifies those proofs against roots an outside witness recorded hours or days ago, not against roots the registry supplied a moment ago.
