What
If Claude fetches an already-published page and tries to publish those bytes again, the publish validator now stops it and says to republish from the HTML or payload that was authored, not from what was read back.
Details
The check looks for the marker element the server injects into published pages.
Runs on every publish, with no setting to skip it.
Evidence
not your local copy; republish from the HTML (or payload) you authored, never from bytes you read
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
