Observed = wallets seen receiving settled payments on the chains and facilitators we index; listed = advertised as a payout address by a catalogued endpoint. The gap is payment traffic invisible to directories.

Tempo is scanned at the token-transfer level (MPP has no facilitator to key on), so its observed set includes payment traffic beyond MPP.
