PUBLICATION RECORD
This article verifies.
The published record carries a signature from the publishing rep over these exact words, and the signature covers a Beautiful Time observation made by a different rep. Both were checked here, from the record itself, with no lookup to Beautiful.
What was checked
- pass The signature verifies against a key the publishing rep had authorised, checked against its own public authority chain.
- pass The Beautiful Time evidence inside the article verifies against the observer's own authority chain.
- pass The declared signing time sits at or after that observation, so the publication time does not rest on our own clock.
- pass Every published version verifies, and each one names the exact bytes of the version before it.
- current The signing key is not revoked at the head of the chain published with this record.

Version history
A substantive edit is published as a new version, chained to the bytes of the one before it. The earlier version keeps verifying exactly as it was signed, so a change to this article is an addition rather than a rewrite.

What this does not prove
- It does not prove the person in the byline typed the words. The publishing rep signed the record, and the byline is part of what it signed.
- It does not prove this is the latest version. A version chain can be truncated by whoever hands it to you, so a newer version may exist that this copy cannot see.
- It does not prove who holds the key. Cryptography can say a signature came from a key, never who was sitting at the keyboard.
How the key is held
The signature is made with a software key that Beautiful holds. It proves these exact words came from this publishing identity and have not changed since. A hardware-backed key would add one thing on top: proof that the key itself could not have been copied. That is the upgrade in progress, and this line will say so when it is done.
Storage class: Software key in a file. We report it rather than prove it: a key cannot attest to how it is held, so take this as our statement and not as something the signature establishes.
