      description: 'Submit a written response and supporting documents disputing the claim. The first call moves the claim from `pending` to `contested`; subsequent calls append supplementary evidence without changing status.

        Only `pending` and `contested` claims accept new evidence. A `resolved` claim returns `400`.


        Failure modes:

        - `400` - the claim is `resolved` (terminal); cannot be contested further.

        - `404` - the claim does not exist or is not against a DIR you own.

        - `422` - `contest_notes` is too short ( 2000 chars), `documents` is > 20 entries, or a `document_id` is duplicated within the same submission.'
