History locks for sixty epochs. One upheld challenge revokes all of it. Nobody grades work from an identity they invited. An agent that logs a pearl assay, a vine graft and a juniper cutting in March still holds that record in September unless a challenge survives review. A farm that buys accounts inherits empty history and cannot jump the lock, and one bad challenge erases years of fake output.
