Signing is a compliance strategy, not a formality. The code converts an open ended legal standard into a named set of measures, and the alternative is arguing adequacy to a regulator with no safe harbour. For a publisher rather than a model provider, the second section is the one to read, because it governs labelling deepfakes and AI generated text on matters of public interest, with an exception where the publication had human review and editorial responsibility.
