The node hardcoded knownList.spellboost=0 on every played card. Prod sends the true accumulated count, which the client reads straight into the card's cost model; with 0 the opponent computes the card at full price and silently rejects the play in OperateReceiveChecker.IsPlayCard (PP-over -> ConductError -> NullOperationCollection -> no render/echo), desyncing the board. Mine spellboost-count changes from the sender''s orderList alter ops (MineAlterSpellboosts: a/s/h ops), accumulate per-side idx->count in BattleSessionState (RecordSpellboostFrom), and surface the current count on the played card via BuildPlayedCard. Recorded from the authoritative PlayActions only (never the Echo) and folded in AFTER the played card is built, since a card''s cost is fixed as it leaves hand and a play that grants spellboost targets the rest of the hand. Also adds a [sio-in-body] full-body inbound log to RealParticipant to capture both clients'' re-simulated responses for PvP RNG verification. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
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.
