// **R298 — a seat's new verb lands in either repository first** (novox/hq issue 298). On 2026-10-07 the
// delivery seat gained `checks`: the seat is defined here and held by a module in the catalogue, and
// neither could merge first — a controller promising the verb refused the holder that did not serve it
// yet, and a holder serving it was refused by the controller that did not promise it. The outcome
// asserted: the holder as it was, and the holder serving `checks` too, both hold the delivery seat.
//
// Written only with what the catalogue package had before the fix (SeatNamed, VerbNames, CanHold), so the
// prover can lay it over that commit.
