【框架设计】限时称号：时效称号的过期与续期

-- 限时称号：到期判定与清理
local player = class(actor)
local function hasValidTitle(player, titleId)
    local expire = tonumber(getplayvar(player, "HUMAN", "TitleExp_" .. titleId) or 0)
    return expire > os.time()
end
function onTitleSweep(actor)
    local player = class(actor)
    for i = 1, 8 do
        local key = "TitleExp_" .. i
        local expire = tonumber(getplayvar(player, key) or 0)
        if expire ~= 0 and expire <= os.time() then
            setplayvar(player, key, 0, true)
            local archive = getplayvar(player, "HUMAN", "TitleArchive") or ""
            setplayvar(player, "HUMAN", "TitleArchive",
                archive .. i .. "@" .. expire .. ";", true)
            sendmsg(player, 1, 0, "称号 " .. i .. " 已到期，可在档案中查看往期荣誉。")
        end
    end

-- 限时称号：续期顺延与叠加
local player = class(actor)
local function renewTitle(player, titleId, addDays)
    local expire = tonumber(getplayvar(player, "HUMAN", "TitleExp_" .. titleId) or 0)
    local base = expire > os.time() and expire or os.time()
    local newExpire = base + addDays * 86400
    if newExpire <= expire then
        sendmsg(player, 1, 0, "续期参数异常，本次续期未生效。")
        return
    end
    setplayvar(player, "HUMAN", "TitleExp_" .. titleId, newExpire, true)
    sendmsg(player, 1, 0, "续期成功，新到期时间 " .. os.date("%Y-%m-%d", newExpire) .. "。")
