preauth

first RPC; echoes SVCN as INST and captures LANG for ALOC


unknown CFIDs still get the shared FUT/POW rows


no auth code yet -> synthesised OPENFUT-<key[:16]> token


routine LoginStateLogout (state 500), NOT a failure; empty reply


login

reply THEN three UserSessions pushes, in that order


the RPC behind 'Unable to retrieve account information'


all four aliases return the same two ONLINE_ACCESS records


TELE/TICK/UROP; TELE.SESS must equal the login session key


empty reply PLUS an unsolicited ExtendedDataUpdate push


non-zero TimeValues or the client storms at ~30/s and hangs the FUT load


session teardown after a login; still an empty reply


msgType PING -> PING_REPLY with an empty body, whatever the command


unimplemented RPC still gets an EMPTY reply so the client cannot hang


same fallback for an entirely unknown component


a reply echoes component/command/msgNum/userIndex verbatim


a non-enUS client: SVCN echo AND the captured locale must both change


UserAuthenticated.ALOC must carry the captured deDE locale
