【框架设计】铭刻系统：专属词条铭刻与唯一性校验

---铭刻：专属词条上装备，唯一性登记
local ENGRAVE_COST_GOLD = 50000

function Engrave.run(actor, makeIndex, word)
    if not checkitemw(actor, "铭刻石", 1) then
        sendmsg(actor, 1, "缺少铭刻石")
        return false
    end
    if not Engrave.takeGold(actor, ENGRAVE_COST_GOLD) then
        sendmsg(actor, 1, "金币不足，需 5 万")
        return false
    end
    -- 全服唯一性校验
    if Engrave.registry[word] then
        sendmsg(actor, 1, "该词条已被「" ..
            Engrave.registry[word] .. "」占用")
        return false
    end
    Engrave.registry[word] = actor:GetName()
    setitemstate(Engrave.itemOf(actor, makeIndex), 4, word)
    takeitem(actor, "铭刻石", 1, 0, "铭刻消耗")
    QF_Broadcast(actor:GetName() .. " 铭刻了专属词条「" ..
        word .. "」，全服唯一！")
    return true
end

---词条的合规与注销
function Engrave.validate(word)
    if #word < 2 or #word > 12 then
        return false, "词条长度须在 2 到 12 个字"
    end
    if Sensitive.hit(word) then
        return false, "词条含受限内容"
    end
    return true
end

---装备销毁后的词条释放
function Engrave.onItemGone(actor, word)
    if Engrave.registry[word] == actor:GetName() then
        Engrave.registry[word] = nil
        -- 释放的词条进入 7 天保护期后重新可命名
        Engrave.cool[word] = os.time() + 7 * 86400
    end
end
