Every member listed here is always written, or left out when null; nothing else appears.",
  "$comment": "`plan_hash` and `rules_version` are the ones `dpl readiness` reports for the same plan, so the questions name the rules of that version. A question's `id` is a hash of its kind and the plan ids it is about, so it survives edits elsewhere in the plan. `dpl missing` exits 4 when some question blocks the assessment of a scene, 0 otherwise.",
