Behavior-identical; 231 BattleNode tests green with ZERO test changes. The 10 handler arms no longer switch on BattleType: - 4 Bot arms gate on the new FrameDispatchContext.OpponentIsAckOnly (Other is not IHasHandshakePhase) — the participant property the audit asked for. - 6 relay arms drop the Type == Pvp guard; it was redundant with BothSidesAfterReady() (only a two-real-player session has both handshake phases). Its doc now records that. - FrameDispatchContext.Type removed (+ the Type = Type in BuildContext). BattleSession.Type stays for the session-level drop cascade. Zero test churn because the stubs already encode the split: FakeRealParticipant/ProbeParticipant implement IHasHandshakePhase, the bot stub FakeParticipant doesn't, and NewBotSession uses it as the opponent.
