Drive ATTACK frames through the headless receive conductor and assert on engine board state (node-native harness). Two cases: follower -> enemy leader (leader life drops by atk, attacker spent) and a lethal follower-vs-follower trade (both removed). ATTACK opcode confirmed = 10 (NetworkBattleDefine.PlayActionType). Headless view-untangle (no Engine logic edits; drift clean): - IBattlePlayerView.AttackSelectControl -> non-null HeadlessAttackSelectControl (no-op RegisterAttackPair/ResetCardAfterAttack); IsCardTranslatable left to base. - IBattleCardView.CardInfo -> backing card via BuildInfo (so IsCardTranslatable reads authentic IsClass); class/null view ctors now chain : base(buildInfo). - IBattleCardView._inPlayFrameEffect -> non-null no-op control. - Seed Certification.viewer_id headless so the IsRecovery target parse (vid != UserViewerID) does not throw inside SavedataManager and silently drop the parsed targetList.

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.
