【数据存储】存档分片：角色数据的水平拆分存储

-- 存档分片：路由读写
local SHARDS = {
    social = {"MateName", "FriendList", "GuildId"},
    asset = {"Wallet_gold", "GearFlow"},
    activity = {"ActFlag", "SignDay"},
}
local function shardOf(key)
    for shard, keys in pairs(SHARDS) do
        for _, k in ipairs(keys) do
            if k == key then return shard end
        end
    end
    return "activity"
end
local function writeKey(player, key, value)
    local shard = shardOf(key)
    setplayvar(player, "HUMAN", shard .. "_" .. key, value, true)
    return shard
end

-- 跨片一致：双写与核对

    if socialGuild ~= newGuild or not assetOk then
        writeKey(player, "GuildId", newGuild)
        sendmsg(player, 1, 0, "数据已自动修复，请重新查看行会信息。")
