/// One reader's request to author or refresh the compact card of one node
/// body, in one language.
///
/// The command names the body version it was written from. That declaration
/// is the whole contract: the kernel refuses the write if the store moved
/// underneath the reader, so an accepted card always describes a body version
/// that actually existed and that the card can be checked against later.
///
/// `authored_at` is stamped by the kernel before this command is built, never
/// taken from the caller: a backdated card would be invisible to a historical
/// read's cut and would leak later text into an earlier answer.
