The OmniRx library, frozen and hashed, so anything you hold can be checked

How to verify

A file. Compute its SHA-256 and compare it with the checksum above. A mismatch means the file is not the one we froze.

The root. Take every fact id in the edition's facts file, sort them, compute the SHA-256 of each id, then repeatedly hash neighbouring pairs (the concatenated hex strings) until one value remains; an odd item pairs with itself. That value is the Merkle root. If it differs, a fact was added or removed. It does not notice a fact whose quote or date was changed, because a fact id does not include them.

The content root. Take each line of the edition's facts file exactly as written, compute its SHA-256, sort those by fact id, and combine them with the same pairwise rule. If this value differs, any fact record was altered: a quote, a read date, a method or a licence label. The verifier at scripts/omnirx-library/edition-sign.mjs verify recomputes both roots, every file checksum and the signature from the files alone.

The signature. Editions frozen from 2026-11-10 carry an Ed25519 signature over the manifest. A signature proves the manifest is the one the key holder signed; it proves nothing about the key holder, so compare the key fingerprint with a copy published somewhere other than the file you are checking.

A receipt. An answer lists the facts it rests on and the edition root. The fact ids must exist in that edition, and the root must appear in the list above. Neither check proves the facts are true, only that they are the facts we recorded, unaltered, with the source and date each carries. See where every figure comes from.

An edition label can be refrozen when new sources are added. Every freeze is numbered, its roots are kept in the history below and in editions.json, and a refrozen edition is hosted at a new address rather than overwritten, so a root you pinned never silently changes meaning.
