Download File Version

Download the bytes of one version, served exactly as Download File serves the current bytes. Generated documents use compiled artifacts, returning 409 while compiling and 413 above the rendered-size ceiling. Downloading records an audit event. HEAD checks access with the same authorization as GET but skips side effects, returning an empty 200 without payload headers on success. HEAD omits Content-Length; use file metadata to size downloads.

OAuth scope: api:read.

GET/api/v2/files/{fileId}/versions/{version}/content

X-API-Key<token>
