- Reputation now exposes per-counterparty verified counts; the profile card trust-weights each confirmed trade by the counterparty's web-of-trust score (fresh-account rings can't inflate it) and labels Highly trusted / Building / New trader - usePendingTradeConfirmations finds sales a seller recorded that name you but you haven't mirrored; the 1:1 DM thread shows a 'Did you complete this trade?' banner with one-tap Confirm
