The optional body of an approve or deny. A local agent offers its own choices for a permission request; the chosen one's id comes back here. A workspace tool offers none and takes no body. An agent's row with no choice is refused, so two same-intent choices can never collapse.
An agent's questions are answered by approving their row with `answers` (koru-ai D108), one per question by its id: an offered option by label, or the person's own words where the question takes them. Denying the row skips the set. A question row approved without answers is refused.
