Rules beat good intentions
Most AI publishing failures are not judgement calls. A draft went out with no citation because nobody counted the citations; a guarantee survived because nobody was responsible for removing it; a piece was 10 percent edited and described as reviewed. Each of those is a rule that could have been checked in ten seconds and was not, because the check lived in a style guide rather than in the workflow.
The validator makes the rules explicit and mechanical. Human edit share must reach a floor, at least one citation has to be supplied, prohibited claims must be at zero, a named person has to sign, and the attestation has to be given deliberately. When a rule fails the form refuses to record, which is the entire point: a guardrail that can be talked past is a suggestion.
