Ordinal is appended, not inserted. The quote() guard stays, and skipped
items take no ordinal. Empty Desk sections do not render; this carries
forward the negative half of the kept-lane pair. The 1:1 toggle is bound
only when the stage is an image.
PROPOSED. Ruled by the operator 2026-09-23 (flow: a_b, compare this_arc,
voice plain, emblem no). Compare is not in this contract; it follows as r3.
Seam-reviewed against the live module surfaces before the cross-frontier
contract panel returned. Four findings are folded in: Mark.created is a
string, the board is BOOTH_LINKS_BOARD, the bench-read error state, and an
unreadable marks file counting as needing the operator.
