Drive a node-native battle to seat B's turn, then ingest an opponent
PlayActions reveal frame (knownList[{idx,cardId,to:Field}], isPlayerSeat:false)
matching battle_test_cl2's wire shape. The engine's ReplaceReceivedCard.ReplaceCard
-> CreateActualCard -> CreateBattleCardWithGameObject path resolves headless and
seats the substituted card on seat B's board with the wire cardId. No Engine/ logic
edits and no new view shims were needed — the card-creation view surface is fully
covered by the BackGround/icon-anim/play-queue/hand stubs from Tasks 2/3.
Adds InPlayCardId(seat, boardPos) accessor (SessionBattleEngine + harness) to read a
seated in-play follower's true identity, leader-excluded like BoardCount.

SVSim.BattleNode
Socket.IO node-server emulation for in-battle real-time traffic — the second of prod's 4-server
topology. Handles Matched / BattleStart / Deal / per-action PlayActions / Echo /
TurnEnd between a client and a server-side opponent, for TK2 PvP and AI rank battles.
Documentation lives in the outer repo
This project's canonical reference is a single hub doc in the outer SVSim repo (this directory is an inner git repo, so the doc isn't tracked alongside the code):
→ docs/battle-node.md (from the SVSim root) — architecture, the dispatch matrix by battle
type, connect handshake + crypto, BattleFinish wire-result semantics, SIO/EIO event coverage,
reliability (pubSeq/playSeq/Gungnir), wire-format gotchas, where-to-extend, the manual smoke
walkthrough, and the consolidated open-items list.
Relative path from here: ../../../docs/battle-node.md.
Detailed per-URI wire shapes are in docs/api-spec/in-battle/; the hub links into them.
Keep docs/battle-node.md updated in the same change whenever you alter node behavior.
