【策划架构】Lua乐观锁：沙巴克仓库的版本号提交

local function commit(actor, draft)
    STORE = draft                    -- 无版本校验，覆盖他人改动
end

local STORE, VER = {}, 7
local function commit(actor, draft, baseVer)
    if baseVer ~= VER then
        sendmsg(actor, 1, "数据已更新，请刷新重试")
        return false
    end
    VER = VER + 1                    -- 提交即推进版本
    STORE = draft
    sendmsg(actor, 1, "沙巴克仓库 v" .. VER .. " 已保存")
    return true
end
commit(actor, STORE, 7)
