Recipients
tacit recipient outputs use the same on-chain wire shape for classical and class-2 shielded addresses — an indexer can't distinguish a stable recipient pubkey from a per-tx stealth commit. Only the recipient's wallet can confirm by trial-deriving against its viewing key. Outputs paying back to a sender input are tagged as change.
