The Assistive Exemption: Content Provenance Marking and the Compelled Disclosure of Disability

Abstract

Article 50(2) of the EU Artificial Intelligence Act requires providers of generative systems to mark outputs in a machine-readable format so that they are detectable as artificially generated. The obligation carries an express carve-out: it does not apply where the system performs an assistive function for standard editing. The Commission's July 2026 Guidelines define that exception to cover grammar correction, spellchecking, minor stylistic polishing, machine translation, and, expressly, content that only transforms authentic human input through assistive technologies allowing persons with disabilities to communicate. They also confirm that the exception applies per operation rather than per system. So the drafters did consider disabled users. They considered one kind. The carve-out reaches assistive technology that lets a person communicate without altering semantics; it does not reach assistive technology that helps a person compose or organize, and the same Guidelines place summarization and substantive rewriting back inside the marking duty. The line runs through the middle of the disabled population. The first implementations went further still. In August 2026 Anthropic announced that its models mark generated text worldwide, and its own documentation concedes that a detected mark shows only that text may have been processed by the model, naming proofreading, translation, and summarization as uses it cannot distinguish. Two of those three are inside the Commission's exception. The mark attaches anyway, applies wherever the product is offered rather than to output used in the Union, and reaches personal use the Act excludes from scope. The Code of Practice then decides who reads it. It concedes in operative text that watermark detection for free-form text has lower reliability and may produce misleading or low-confidence results, and it nonetheless guarantees access to a named class of expert users that includes educational and research organisations. It requires that a detection result be downloadable as a digitally signed artifact with a content hash and timestamp. It contains no provision entitling the person whose text was queried to notice, to the receipt, or to any route to contest the result. This Article makes three claims. First, that accessibility enters this regime in one direction only: it constrains how a notice or a detection result is delivered to a reader, never who is marked, and the Guidelines state that Article 50 imposes no distinct accessibility requirements of its own. Second, that the resulting position is a compelled disclosure. The mark says nothing about disability; it says machine involvement, and where an institution restricts that involvement the only defense available to an accommodated author is the accommodation. A facially neutral rule answerable only by disclosing protected status is a disability related inquiry in substance, and existing doctrine already says so. Third, that no doctrine reaches the injury when it occurs. The provider that creates the signal owes the marked person nothing; the institution that acts on it holds a guaranteed right of access and did not create it. Accommodation law is built for a dyad. Provenance marking makes a triad whose third element is a property of the artifact.
