Behavior-preserving; full solution builds, 1013 tests green. ClassId is the one genuinely-closed set of the three flagged stringly fields, so it becomes a CardClass enum (1..8). Wire stays "1".."8": producer casts (CardClass)run.ClassId, ServerBattleFrames renders via CardClassWire.ToWireValue(). RankBattleController's AI-start path drops a fragile int.TryParse(...)?:-1 for (int)cast. CharaId (free-form leader/skin id, e.g. "5000123") and CountryCode (open-ended account data) stay string with proper XML docs; CountryCodes.Korea/Japan name the captured values.

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.
