Zaps are signed as the person zapping: the login identity (extension, bunker, passkey, Google) when there is one, else the wallet's key. They were always signed by the wallet's own key, so a signed-in person's zaps showed in stream chats and streamers' overlays under a stranger npub. Zap requests also carry created_at now (a real signer refused them without it).
