In `@dsh-mneme/src/dream/sleep.js`:
- Around line 689-696: Update the sleep scheduler’s onRun callback to pass its
recorded start time through to runSleep, and extend runSleep to accept that
value and write it as created_at in the sleep audit record. Preserve the
existing behavior when no start time is provided.
In `@dsh-mneme/src/index.js`:
- Line 462: Update the lastRunAtSeed assignment near store.lastDreamRunAt in
dsh-mneme/src/index.js at lines 462-462 to call lastDreamRunAt with the "auto"
type filter. Apply the same change in dsh-mneme/lib/index.js at lines 462-462 so
sleep audit entries cannot be treated as the previous dream run.
In `@dsh-mneme/src/store.js`:
- Line 1547: 将调度器记录的开跑时间从 createDreamScheduler 的 onRun 回调传递到 runDream，并在唯一的
saveDreamRun 审计写入中用该时间设置 created_at；仅当时间有效时覆盖默认值。对 src 与 lib 中对应的
createDreamScheduler、runDream 和 onRun 调用链应用相同修改，保留成功、失败及 degraded 状态共用现有审计路径。
In `@dsh-mneme/test/lastrunat-persist.test.js`:
- Line 33: Inject a controllable clock into createDreamScheduler and use it for
both the minIntervalMs check and lastRunAt updates. In the lastrunat persistence
test, capture one fixed timestamp and use it for both the seeded created_at
value and the scheduler’s clock so the 10 ms interval remains deterministic
without faking timers.
- Around line 35-43: Update the restart test to create autoDream through the
real startup path instead of passing lastRunAtSeed directly to
createDreamScheduler. Seed a recent auto run, configure a nonzero
dreamMinIntervalMinutes, trigger the write notification with
service.saveWithDedupe, and assert onRun is not called during the cooldown; the
assertion must fail if the startup wiring that supplies the seed is removed.
- Around line 47-73: 扩展 sleep 回归测试，使其通过生产启动接线获取持久化的 sleep 运行时间，而不是直接传入
lastRunAtSeed；验证启动流程调用 store.lastDreamRunAt("sleep") 并将结果传给 sleep 调度器。保留首次 idle
触发被 cooldown 阻止的断言，并确认计时器会在剩余 cooldown 结束时重新安排。

为 dream 调度器注入固定时钟。
当前测试将上次运行时间设为 Date.now() - 10，但闸门只拦截间隔小于 5000 毫秒的调用。如果写入到 maybeSchedule 之间超过 5 秒，闸门会正确放行。测试记录已满足触发阈值，maybeSchedule 会返回 true，导致断言间歇性失败。固定 now 即可稳定测试 10 毫秒间隔；此断言路径不会创建定时器，无需伪造定时器。

增加真实启动路径的 autoDream 重启断言。
当前测试直接向 createDreamScheduler 传入 store.lastDreamRunAt()。因此，移除 src/index.js:462 不会改变该测试的输入，测试仍可能通过。
请通过真实启动路径创建 autoDream，预先写入最近的 auto run，再通过 service.saveWithDedupe(...) 触发写入通知。设置非零 dreamMinIntervalMinutes，并断言冷却期内不会执行 onRun。移除 src/index.js:462 时，该断言必须失败。
这个缺口是实质性的。现有测试覆盖调度器内部逻辑，但没有覆盖本次修改的启动 wiring。缺少该 wiring 时，重启后的 autoDream 可以立即再次触发。

slow-stack#89 的最小间隔闸对失败 run 也生效，但间隔恒定——恒定失败的模型（slow-stack#135 空体面）按固定节奏连发刷配额。新增 opt-in 键 autoDreamFailureBackoff （默认关 = 行为逐字节不变）：有效最小间隔 = dreamMinIntervalMinutes × 2^连续失败数，封顶 30 分钟（只拦增长，不把用户配得更大的基数压小）； 成功一次清零，重启归零（跨重启冷却归 slow-stack#291 的 lastRunAtSeed）。被退避 推迟的触发没有调用发生，不写审计行（与 slow-stack#89 间隔内跳过同口径）。 config.js schema 与 settings.js 白名单成对注册；api.test.js 旗标计数锁 按累加口径 +1 并补 effective 断言；新增 test/dream-failure-backoff.test.js 5 例（注入时钟，同 dream-peak-hours 房型）：默认关间隔不变 / 连败 2 次 第 3 次推迟 / 成功清零恢复 / 连败 10 次封顶 30 分钟 / 0 基数不产生间隔。

slow-stack#291 只把时间闸门 lastRunAt 从 dream_runs 恢复了回来，阈值基线 baseline{count,chars} 仍是调度器闭包里的内存变量，进程重启归零。库里记忆远多于阈值（默认 10 条 / 5000 字符）时，重启后第一条写入（notifyWrite → dreamHook → maybeSchedule，更新类写入同样 计入）就让 overBase 成立——阈值被整个绕过，直接开跑一整轮巩固。 0.8.11 实测一天四次重启，其后第一轮巩固发生时窗口内只新增 6 / 7 / 0 / 8 条记忆 （1427 / 1488 / 0 / 1509 字符），每轮约 16 万 tokens（consolidate ≈7.5 万 + 总览 ≈8.8 万，llm_audit_logs 实测）。 - dream_runs 增 store_count / store_chars 两列（幂等迁移，两列同时有值或同时为 NULL）， 成功轮才落「本轮结束后的活跃库规模」，失败/降级不推进基线的既有语义不变； - 调度器构造新增 baselineSeed，启动时按 run_type='auto' 播种；认不出行（新库、升级后 还没跑过成功轮、老行两列为 NULL）退回零基线，行为与升级前逐字节一致； - 阈值口径抽成 activeStoreSize() 单一实现，shouldTrigger 与落库共用，避免两条路径 口径漂移（那种漂移只在重启后才显形）； - run 自报的基线与审计行是同一份数字，进程内刷新改用它，两条路径不再各算一次。 回归集 7 条（test/baseline-persist.test.js）：无种子对照组与播种组同库同写入、阈值照常 累积、run 自报基线优先、成功轮落库/失败轮不落、sleep 行不进 auto 基线、半个基线被拒、 老库补列幂等、index.js 接线源码锁。变异检验：忽略种子 → 2 条变红；短路落库分支 → 1 条 变红。全量 npm test 1447 通过 / 0 失败（1 条 Windows 符号链接用例既有跳过）。

Closes #89（残留缺陷：lastRunAt 未持久化导致的重启后连发）。
背景
#89 主体（skipInvalid 宽容路径）已随 v0.7.22 修复并验证。线程末端定位出连发的根因：两个调度器的
lastRunAt只活在内存里，进程重启即归零——最小间隔 / 冷却闸对新实例直接放行。实测证据（原 issue 内）：
degraded(auto)与下一条degraded(auto)gap=8.7min，恰好横跨进程重启边界；修法
审计表恢复，零 schema 迁移、零新配置键：
store.lastDreamRunAt(runType)：读dream_runs最近一次 run 的created_at（epoch ms）；审计表本来就逐 run 落库，failed/degraded 也算 run——重启连发的正是这些失败轮；createDreamScheduler({ lastRunAtSeed })：index.js构造时注入store.lastDreamRunAt("auto")——最小间隔闸门（dreamMinIntervalMinutes）重启后立即生效；createSleepScheduler({ lastRunAtSeed })：注入store.lastDreamRunAt("sleep")——冷却闸（sleepMinIntervalHours）同理。同族缺陷一并修掉，不留给下一个 issue；created_at改记开跑时刻（runDream/runSleep入口自记）——run 耗时（含 LLM 各 phase）不应计入重启后的间隔/冷却窗口。调度器默认种子
0= 行为与旧版完全一致，测试双注入（审计读回 / 直接种子）两不误。验收
test/lastrunat-persist.test.js5 用例：审计读回与 run_type 过滤（含空表 → 0）、dream 调度器带种子后重启场景闸门立即生效、sleep 冷却重启后按剩余窗口重排（[Bug] sleep 排程：计时器撞上 sleepMinIntervalHours 后不重排，整轮被静默丢弃 #187 语义不回退：不丢触发权、+1s 守卫）、index.js 接线源码锁 ×2（dream="auto"/ sleep="sleep"，删注入行即红）；npm test：1290 tests / 1289 pass / 0 fail / 1 skip（套件总数，含平台跳过），npm run sync已跑（src↔lib 平价锁通过）；备注
