// Only the id is strictly required by the wire contract — the client reads its own
// ChallengeConfig for names / counters / rewards — but Tag and Type
// are kept so the login fill can be scoped later (e.g. publish only 赛车挑战 201) without
// regenerating the table.

// Build-4229938 challenge catalog (T0-2). The source table is ChallengeConfig.json, which does not
// ship in the v0.3 Configs folder; it comes from 补丁和工具\ConfigDump.zip. Regenerate with
// _gen_challenge_cfg.py.
// Both challenge dictionaries travel in the login payload and the client does read them:
// lua/LX6/Data/Player/PlayerData/PlayerInfoAchievementData.lua:12-13
// t.ChallengeRecordInfo    = info.InfoAchievement.ChallengeRecordInfo
// t.NewChallengeRecordInfo = info.InfoAchievement.NewChallengeRecordInfo
// ⛑⛑ The two are dictionaries, not lists — authoritative shape from
// lua/LuaGen/AutoGen/RPCDeserializeAuto.lua (Auto.Reader[1305]):
// ChallengeRecordInfo    = ReadDict7Bit(u32 key -> Complex(Reader[381]))
// NewChallengeRecordInfo = ReadDict7Bit(u32 key -> Complex(Reader[594]))
// The only other place ChallengeRecordInfo appears is GameToClientImpl.lua:1099
// (SyncCompletedChallenge), which does table.insert(...) on it — appending an *integer* key into
// the dictionary after login. That is a separate S2C channel and a client-side quirk; it does not
// change the dictionary shape the login payload has to emit.
