/// ─────────────────────────────────────────────────────────────────────────
/// PICKED IS NOT OUT FOR DELIVERY
///
/// ── The regression ──
///
/// The release used to ride along with `pickup-complete`: the rider slid to
/// confirm five bags at a counter and the same gesture posted all five
/// consignments `Out_for_Delivery`. The hub's board then showed five **active**
/// deliveries for food still on the shelf in front of him, and the day had no
/// moment left in it meaning "I have set off" — picked and out-for-delivery had
/// been collapsed into one claim.
///
/// They are two claims about where the load is, made an hour apart, and only
/// the rider can make the second one. The ladder the hub sees is now:
///
/// ```
///   pickup-complete ──▶ Converted_To_Consignment   admin: picked
///   START DELIVERY  ──▶ Out_for_Delivery           admin: active
///   deliver         ──▶ Delivered                  admin: delivered
/// ```
///
/// These are the pure halves of that — the rung ladder and the stores it reads.
/// The press itself lives in `MyPickups.startRound`.
