Suggested reviewers: Merge Risk: 🔵 Low · up to The default defer limit works, but users cannot tune it in the settings panel. This is a bounded configuration gap with an API workaround, so merging is reasonable if that limitation is acceptable. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The new scheduling controls do not appear to bypass the existing settings authorization. Two opt-in scheduling cases could nevertheless delay consolidation longer than intended: a restart can discard a pending run, and consecutive peak windows can exceed the configured deferral limit.

`summarizePeakHours` 的错峰目前只覆盖蒸馏，巩固（autoDream）没有任何时间窗——而它是 另一个 LLM 大户：单次 run 的输入是整窗快照（dreamMaxSnapshotSize 条），一次调用可达 分钟级，且由写入事件触发、没有天然的「等到空闲再跑」路径。 - 新增 `dreamPeakHours` / `dreamPeakMaxDeferMinutes`：与蒸馏侧**同一份时段语法与解析** （直接复用 src/summarize.js 已导出的 parsePeakSpec / isInPeakWindow / nextOffPeakAt， 不另写解析器——两份实现漂移会让同一个时段串在两处行为不同，那比没有这个功能更糟）。 空串 = 关闭，行为与现状逐字节一致。 - 命中高峰：不调 LLM、**baseline 不刷新**（阈值继续累积，留到非高峰一次性巩固——一次 大 run 比多次小 run 省），登记一行 status='skipped' / error_message='peak-hours' 审计（沿用第 4 项口径：skip 原因必须对用户可观测），并顺延到最近的「高峰结束」时刻 补跑；被 peakMaxDeferMinutes 截断后到点仍处高峰则放行，避免长高峰把巩固饿死。 - 与蒸馏的形态差异：巩固是**全局单实例**，所以只需要一个 deferTimer，不需要 deferredRuns 那套按会话去重；顺延期间新的写入触发不叠加定时器、不重复刷审计行。 - 时钟与定时器可注入（now / setTimeoutFn / clearTimeoutFn，同 dream/sleep.js 的房型）： 排程不绑死真实时钟，「高峰顺延 → 非高峰补跑」才能被确定性覆盖，也不会在 CI 上留下 真实等待。为此把开跑路径抽成 startRun()，正常触发与顺延补跑共用同一条收尾逻辑。 - 面板：巩固侧时段输入挂在 autoDream 子块内（开关关掉时不该还留着可编辑的输入框）； 顺带把此前只有后端白名单、面板调不到的 `summarizePeakHours` 一并渲染——两个错峰键 一个能调一个不能，比都不给更让人困惑。双语文案齐。 - 白名单与文档：config.js schema + settings.js 成对注册（strings + int ranges）、 test/api.test.js 旗标计数锁 +2、README 两个键的文档行。 - 回归 7 条（test/dream-peak-hours.test.js）：命中高峰不调模型且写审计、顺延到点补跑、 重复触发不叠加、上限截断放行、非法时段串按未配置处理（宁可不省也不误停）、非高峰 行为不变、dispose 清掉顺延定时器。 - 全量 npm test：1391 条（基线 1384 + 7），失败集合与上游 main **逐条一致**（9 条 runtime-verify 的环境相关用例，对照实验见 PR）。

CodeRabbit review 抓到的真问题：rebase 到含 slow-stack#316（summarizeReasoningEffort）的 main 时，我在 autoSummarize 子块新加的 `const summarizeSub` 与上游同名声明撞车—— `node --check lib/client.js` 报 "Identifier 'summarizeSub' has already been declared"， 面板 bundle 一执行就抛 SyntaxError，整个设置页加载失败。而当时 CI 全绿。 - 把错峰时段输入**并入上游那个 summarizeSub**（保留思考强度下拉与其 hint）， 而不是并列第二个声明。 - 补一道解析闸（test/client.test.js）：该文件此前只把面板当**文本**读（断言全是 正则/字符串包含），仓库 CI 里没有任何一步解析 lib/client.js，而 lib/client.js 无 src 对应物、不参与 sync —— 于是这类语法错误能全绿进主干。新增用例用 `node --check` 解析产物；已实测「注入重复声明 → 该用例失败、还原后通过」。 - 全量 npm test：1399 条，失败集合仍与上游 main 逐条一致（9 条 runtime-verify 环境相关用例）。

review slow-stack#320：slow-stack#316 之后 summarize.js 反向依赖 dream.js（withEffortFallback 复用），dream 镜像错峰再 import summarize 会成真循环。把 parsePeakSpec / isInPeakWindow / nextOffPeakAt 抽到零依赖模块 src/peak-hours.js（纯搬移）， summarize.js import + re-export 兼容既有调用方与测试，dream.js 改从新模块 import。顺带修正原注释里「summarize 不反向依赖 dream」的过时事实。
Review 结论与处置（modusensus，合并前本地修复）
修复后本机全量验证：1399 tests / 1398 pass / 0 fail / 1 skipped（平台跳过），src↔lib sync 平价（lib-smoke 抓过一次漏同步，已重新 sync 解决）。感谢高质量实现——审计诚实性、baseline 不刷新、上限放行三个语义都落得干净，测试注释把防的回归写得很清楚。 |

summarize.js的错峰机制镜像到dream.js（巩固）问题
第 4 项的错峰目前只覆盖蒸馏。巩固是另一个 LLM 大户，且完全没有时间窗：
turn/enddreamMaxSnapshotSize，默认 200 条）summarizePeakHours（#239 第 4 项）后果：白天交互密集时写入频繁 → 巩固恰好在最需要算力的时候开跑，且它没有「等到空闲再跑」的路径。
方案
新增两个配置键，opt-in，空串/默认 = 行为与现状逐字节一致：
dreamPeakHours""summarizePeakHours同一份时段语法：逗号分隔、可带星期前缀（mon-fri/1-5）、支持跨零点。空串 = 关闭dreamPeakMaxDeferMinutes120行为（命中高峰时）：
status='skipped'/error_message='peak-hours'审计——「为什么不再做梦了」必须对用户可观测；dreamPeakMaxDeferMinutes截断后到点仍处高峰则放行，不进入无限顺延。为什么是镜像而不是直接复用
summarizePeakHours两者是互补语义，不是同一个开关：
deferredRuns去重），因为蒸馏窗口是会话局部状态；deferTimer，不需要按会话去重——直接用蒸馏那套反而要引入无意义的会话维度。时段解析本身复用（
parsePeakSpec/isInPeakWindow/nextOffPeakAt已从summarize.js导出），不另写一份——两份实现漂移会让同一个时段串在两处行为不同，那比没有这个功能更糟。summarize.js只依赖dsh-llm与lang.js，不反向依赖dream.js，无循环引用。改动面
src/config.jssrc/settings.jssrc/dream.jsstartRun()供两条路径共用；时钟/定时器可注入（同dream/sleep.js房型）src/index.jsrunAuditedLlm一致：审计关掉就不写、写失败只 warn）lib/client.jssummarizePeakHours一并渲染（双语文案齐）。这一处属可选，希望 PR 更小可以摘掉test/dream-peak-hours.test.jstest/api.test.jsdsh-mneme/README.md验证
新增回归 7 条（
node --test test/dream-peak-hours.test.js，7/7 通过）——时钟与定时器全部注入，排程不绑死真实时钟：dispose清掉顺延定时器全量
npm test：1391 条（基线 1384 + 7），失败集合与上游 main 逐条一致。9 条失败全在
test/runtime-verify.test.js（自管运行时/三件套校验），是本机环境相关的既有失败：对照实验用git worktree add … upstream/main检出干净 main、软链同一份node_modules，两次运行的失败用例名集合diff为空。与本改动无关。npm run sync+scripts/check-sync.js：✓src/与lib/一致（49 个文件）。兼容性
dreamPeakHours: ""→parsePeakSpec返回null→ 闸门恒不命中，调度路径与现在完全一致；dream_runsschema、不加迁移；skip 只落一行llm_audit_logs（该表本就有skipped状态与metadata列）；now/setTimeoutFn/clearTimeoutFn）都有默认值，既有调用方无需改动。待确认
dreamPeakMaxDeferMinutes默认取 120（与summarizePeakMaxDeferMinutes对齐）还是 0（不设上限）？我按 120 实现，改默认值只是一行。Summary by CodeRabbit
