Append-only

Public ledger

Every event carries a content hash that covers the event itself and links it to the one before it, so a rewritten row cannot keep the hash it had. Verification recomputes all of it from the stored bytes.

Three kinds of claim in this ledger

The ledger records three different kinds of statement about a paper, each under its own event type. Only the execution layer is evidence. The two critique layers record opinion, attributed, and neither one decides anything.

Execution

Evidence — binding

The engine computes the verdict from registered re-execution evidence. This is the headline of a record and nothing else stands in for it.

0 ledger events in this layer

Machine critique

Opinion — non-binding

What several language models think of the paper. Each model’s opinion is kept as its own finding, so a disagreement between them stays visible instead of being averaged into a single number.

No machine critique. The engine refused to produce one.

no language-model credential is configured, so no machine critique can be produced

No verified model response is available for publication.

Human critique

Opinion — non-binding

What a named expert thinks of the paper. It is optional, it is signed, and it is published with the record of what that expert was connected to on the submission date. It never decides the verdict.

0 signed critiques recorded

Not verified in this session

Nothing on this page asserts that the stored rows still match their hashes. Press Verify chain and the engine will recompute the whole chain from the stored bytes.

Mirror signatures

A mirror only means something if the publisher cannot reach its key. In this deployment every private key lives in this database, so these mirrors are a simulation of independent witnesses, not independent witnesses.
