【运维发布】复盘模板：时间线、根因与行动项

---复盘报告：标准模板的七段结构
local REPORT = {
    summary = '',       -- 一句话事故名
    level = '',         -- P0/P1/P2
    timeline = {},      -- 时间轴
    impact = {},        -- 影响面
    rootCause = '',     -- 根因
    why5 = {},          -- 五问
    actions = {},       -- 改进项
}

---时间轴的节点
function Report.addTimeline(rpt, time, event)
    rpt.timeline[#rpt.timeline + 1] = {
        time = time, event = event,
    }
end

---改进项的跟踪：逾期升级的自动化
setontimerex(148, 3600)
function Report.trackActions()
    for _, rpt in pairs(Report.store) do
        for _, act in ipairs(rpt.actions or {}) do
            if not act.done and os.time() > act.deadline then
                Ops.alert('改进项逾期', rpt.summary,
                    act.task, act.owner)
                act.escalated = true
            end
        end
    end
end
