feat(mo): 接通自动沉淀——工作流从「挖得出来」到「会被叫去挖」 - #489
Merged

Conversation
pipeline-nudge.js 从 v0.9.1 起就能把多帧会话日志挖成「重复动作 → 缺席对照 → draft 草稿」，但全仓引用只在 test/ 里，运行时零调用点。缺的不是算法，是归属与 触发：nudgeFromSessions 要的是某个项目的会话桶目录，而桶名是路径的有损变形， 唯一可信来源是会话头里的 cwd。 - resolveProjectSessionDir 用 cwd 反查桶；查不到就整跑跳过，不降级成全局普查 （后者会把 A 的动作算到 B 头上，且结果看起来完全正常） - nudgeForProject 把「归属 → 挖掘 → 落盘」收成一个入口，调用方没有机会漏掉 - 新 pipeline-nudge-auto.js：挂在 turn/end，按项目 10 分钟冷却、单次 4 秒预算、 延到 setTimeout(0)（解压是同步 I/O，压在回合收尾那帧上等于每轮都卡一下）、 一次只跑一个项目、抛错只 warn 不冒泡 - 自动跑恒 materialize:false，只产提议不产草稿；升格仍要人批 - 新旗标 actionNudgeEnabled，默认关、进 LIGHT_MODE_OFF，与看图 / 记账三件独立 - GET /nudge 只看不写，POST 真跑一次；因落盘是写，policy 是 token-write - nudgeFromSessions 原先只要算得出项目键就无条件写提议，而面板每刷一次就 GET 一次 —— 抽出 persistProposals，预览路由显式关掉 - 面板加「现在沉淀一次」，九句双语回执；读不到 cwd 时禁用；禁用态用虚线边而 不是降 opacity（会把文字压到 AA 以下） - 术语「手法」统一改回「工作流」：src 24 处、面板 3 处、文档 11 处；已发版的 CHANGELOG 与测试夹具词不改（历史不追溯，夹具锁的是路线图插入逻辑）

四条用例分开守 policy 三态、绝对路径、503/200 分叉、GET 不落盘；后者是接线时抓到的真 bug（面板每刷一次就 GET 一次，原先会往 memoryDir 塞文件）。 顺手把「跨项目不并账」从固定 tick(30) 改成等待条件：队列是链式排程，全量跑时并发解压会把一次 setTimeout(0) 拉长，假阴性只在满载 CI 上出现。

🌐 Web query:
@deepseek-ai/dsh-host-webserver 0.2.0-rc.1 webServer.register route method contract
💡 Result:
For `@deepseek-ai/dsh-host-webserver`, `webServer.register(route)` registers one named HTTP route:
- `route` is an `exact` or `prefix` route.
- Exact matches take precedence over prefix matches; among prefixes, the longest match wins. If none match, the fallback handles the request.
- Duplicate paths in the route table throw.
- It returns a disposer that removes the registration. Register it inside the plugin’s lifecycle/effect so cleanup runs when the plugin is disposed. ([github.com](https://github.com/deepseek-ai/deepseek-harness/blob/master/packages/host/webserver/README.md))
**Version caveat:** the source available here is the repository’s current `master`, not the published `0.2.0-rc.1` implementation. So this describes the documented current contract; I can’t verify that every detail is identical in `0.2.0-rc.1`.

🌐 Web query:
site:github.com/deepseek-ai/deepseek-harness "0.2.0-rc.1" webserver register method req.method
💡 Result:
For **`dsh-v0.2.0-rc.1`**, `webServer.register()` doesn’t take a method field: `WebRoute` contains only `kind`, `path`, and `handler`. The handler receives Node’s `IncomingMessage`, so you can branch on `req.method` inside one handler. Registering the same route twice to split methods will throw a duplicate-route error. ([github.com](https://github.com/deepseek-ai/deepseek-harness/blob/dsh-v0.2.0-rc.1/packages/host/webserver/src/index.ts))
Example (illustrative, not quoted from the source):
```ts
ctx.webServer.register({
kind: 'exact',
path: '/example',
handler: (req, res) => {
if (req.method === 'GET') { /* ... */ }
else if (req.method === 'POST') { /* ... */ }
else { res.writeHead(405).end() }
},
})
```

拒绝未声明的方法，避免空请求体触发写入。
webServer.register() 不按 HTTP 方法过滤路由。带有效 token 的 PATCH、DELETE 等请求会进入此 handler。当前分支不会读取请求体，而是执行 run(null)。persistProposals 对这些方法为 true，因此有候选时会把提议写入 memoryDir。请对非 GET、HEAD、POST、PUT 的方法返回 405。

将归属解析纳入运行预算。
resolveProjectSessionDir 在自动运行和 /nudge 请求中都会先执行，但 budgetMs 只在归属解析完成后由 nudgeFromSessions 转换为 deadline。归属解析因此可以超过自动运行的 4 秒预算，或 API 调用的 4 秒、12 秒预算。
findSessionFiles 会先递归遍历整个桶，再截取前 3 个文件。readSessionCwd 会同步读取完整文件；首帧没有 cwd 时，forEachZstdFrame 会同步解压全部 zstd 帧。500 个桶的上限不能限制单个桶的递归成本或单个文件的解压成本。
请在每次运行的入口先计算同一个 deadline，再将它传入 resolveProjectSessionDir 和 nudgeFromSessions。目录遍历、文件读取和帧扫描都应在可中断边界检查该 deadline，并返回可识别的 budget-exceeded 结果。请同时限制 readSessionCwd 的回退解压帧数。仅在桶循环开始处检查 deadline 不足以覆盖 findSessionFiles 的完整递归遍历或单个文件的同步解压。
修改后运行 npm run sync 同步 lib/。

三处评审发现，逐条修，每处都带能咬住的回归锁： 1. 写盘口：/nudge 的方法分流只拦 PUT/POST，其余直落 run(null)； 而 persistProposals 按「不是 GET/HEAD 就算写」算，于是带 token 的 PATCH/DELETE 会走进写入分支、把提议落进 memoryDir——一个不需要 body 的静默写盘口，与这个端点「GET 只预览、写动作一律要 POST」的卖点相反。 改为入口白名单（GET/HEAD/POST/PUT），其余 405 + Allow 头，在 readBody 之前拦。测试锁两件事：状态码与 Allow 头都对，且 memoryDir 下一个文件 都不许出现（只看状态码会漏掉「先写再报错」）。 2. 预算外路径：resolveProjectSessionDir 最多同步扫 500 个桶 × 3 个文件， 原先完全不看 budgetMs，于是「真卡就调 budgetMs」这句话对归属解析这 一段是空话。现在它接 deadline，桶循环与文件循环里各查一次；超时回 新 reason budget-exceeded，而在 /nudge 上按环境问题报 503（扫描没跑完 不是「这个项目很干净」的答案），error 码与 unreadable 分开。 nudgeForProject 自己按 now+budgetMs 算同一条截止线并转交给解析，避免 「解析用 A 截止、挖掘用 B 截止」的双预算。 注意：budgetMs 为 0 或不给时仍扫到底——测试与离线批处理要完整结果。 3. 注释：config.js 里 actionNudgeEnabled 的说明写「30 分钟/项目」， 实际 NUDGE_AUTO_MIN_INTERVAL_MS 是 10 分钟。改成 10 分钟并注明以 常量为准。 验证：新增 3 条测试（405 白名单含不落盘断言、解析超预算、nudgeForProject 超预算）；精确变异两处各自咬住（放开白名单 → 405 测试红；outOfBudget 恒 false → 两条预算测试红），还原后全绿。npm run sync 74 文件，全量 2250 tests / 2249 pass / 0 fail / 1 skip。

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
会话桶数量超过上限时，不应报告为 no-bucket。
问题如下：
- 循环在
readdirSync返回的原始顺序上收到maxBuckets（500）个桶就退出，之后才sort()。这个顺序由文件系统决定，所以被扫描的 500 个桶不固定。 - 目标项目的桶落在被截掉的部分时，函数返回
reason: "no-bucket"。 - 函数注释把
no-bucket定义为「扫完了，确实没有」。/nudge路由对这个原因返回 200 和skipped。
结果：一次截断被报告成「这个项目没有会话」。这正是本文件要区分的「读不到」与「确实没有」。
建议修复：先收集全部目录名并排序，再截取前 maxBuckets 个。如果发生截断且没有匹配，返回单独的 reason，例如 bucket-limit。在 src/api.js 中把这个原因归入返回 503 的环境问题。

评审第二轮抓出的同类缺陷，与 budget-exceeded 是同一个病根——「没看全」被 报成「确实没有」： - 收集桶名时是**边收边截**：数到 maxBuckets（500）就 break，之后才 sort()。 于是留下哪 500 个由文件系统遍历顺序决定，同一个 maxBuckets 在不同机器、 不同时刻留下的是不同的桶。 - 目标项目的桶一旦落在被截掉的那部分，函数返回 no-bucket，而函数注释把 no-bucket 定义为「扫完了，确实没有」，/nudge 路由对它回 200 + skipped。 结果是一次截断被当成「这个项目没跑过会话」。 改法（与 findSessionFiles 的既有规矩对齐：先收全、再排序、最后截断）： - 先收全部目录名，sort() 之后才 slice(0, maxBuckets)； - 新增 reason bucket-limit，与 no-bucket 分开；返回里加 bucketsTotal 与 bucketsTruncated，截断这件事从此是可读的读数而不是隐含条件； - /nudge 把 bucket-limit 归入环境问题回 503（error 码 nudge-attribution-bucket-limit），与 budget-exceeded 并列。 三处 budget-exceeded 返回点也一并带上 bucketsTotal/bucketsTruncated， 否则「超预算」和「截断」两个读数在不同出口上形状不一致。 测试：新增一条锁住三件事——截断且未命中报 bucket-limit 而非 no-bucket、 放宽到能覆盖目标桶时按字母序命中（证明留下谁由排序决定）、不截断时 bucketsTruncated 明确为 false。变异验证：把 bucketsTruncated 恒置 false， 该测试红；还原后全绿。 一处如实说明：把 sort() 去掉（先截断）这个变异**没有被测试咬住**——测试 用的临时目录里 readdirSync 的返回顺序恰好就是字母序，两种写法结果相同。 要真正覆盖这一条，得有一个能控制 readdir 顺序的注入点；这超出本次修复的 范围，记为已知覆盖缺口，不假装它被锁住了。 验证：npm run sync 74 文件；全量 2257 tests / 2256 pass / 0 fail / 1 skip。

The profile card only ever had a pen on it: whatever the store accumulated never came back as a view of the user. This adds the other direction — read the active memories, spend one host-LLM call, return an "as the assistant sees them" draft. Three edges are hard requirements, not preferences. The module never receives `settings` at all: the draft is applied by an explicit panel action that PUTs /profile, because profile prose is hand-written and letting the model "merge" it hands it rewrite rights over text injected every turn. An empty store is refused before the call — a model inventing "she loves learning" from nothing is worse than no draft, since that draft becomes the first version of the user the person sees about themselves. Output that is not the required JSON object is an error, never an empty draft; no-input, unparseable and a dead stream are three distinct HTTP outcomes so the panel can say three different sentences instead of reporting a fault as an empty result (#489's lesson). Memory text is model-influenceable input, so rows go in inside a fence with the role restated in the system turn (same stance as #493's transcript fence), and the system turn forbids naming or personifying the assistant: profile and rules are not governed by personaEnabled nor by card addressing, so a "you are X" line in the profile would re-run the #497 identity collision in every session. Auditing reuses dream's seam (streamText / runAuditedLlm / resolveRoute) rather than re-deriving chunk shapes that were already paid for; only the export list changed. Policy is `token`, not `token-write`: the route has no read branch (non- POST is 405 before readBody — after it, a bodyless method wedges on the read), and declaring a read-open branch would have slipped past SECURITY.md's open-read list, which test/security-doc.test.js exists to catch. Off by default and in LIGHT_MODE_OFF.

…498) * fix(persona): scope the default card and render the panel preview from one source (#497) Two defects with one root: addressing and rendering each had a second implementation that disagreed with the first. Addressing. A session identity with no card — or whose card was explicitly switched off — fell back to the default card. With a default card enabled, every unregistered identity in the host (including bots that carry their own identity and settings) received "your persona name is ..." in every turn, and the panel's "disable this card" toggle disabled nothing. agent_scope is a model-settable parameter, so it is not a boundary. New opt-in `personaStrictAddressing` (default false: existing installs see byte-identical injection) makes both cases inject no persona, so the default card only covers sessions whose identity cannot be resolved at all — its original intent. Rendering. The panel's "you, as the agent sees you (injected text)" card was hand-spliced in the frontend: profile and rules bullets only, no [User settings] header, no "- Profile:" prefix, and no persona lines at all, while claiming to show what the model sees. The block now lives in src/user-settings.js (escapePromptVars / resolvePersonaCard / renderUserSettingsBlock), which the injector and GET /persona's new `preview` field both call; the panel displays the backend string and fails closed to "unknown" instead of guessing. ?agent=<id> previews per card. settings.getPersonaFor lost its last production caller and is deleted, so addressing exists in exactly one place. Tests: strict addressing (4) plus one lock that the default path is unchanged; preview byte-identical to the injector for three identities; gate-off reporting truthfully; panel must not regress to frontend splicing. Mutation-checked: removing the strict branch reddens 4 tests, and making preview ignore ?agent reddens 3 including the byte-equality one. Flag lock 104 -> 105, whitelist pair, CONFIGURATION.md rows, both languages. Not done here, deliberately: a switch for profile/rules (older than persona and gating it would change behavior for everyone), extracting a profile from memory (no such pipeline exists — that is a feature), and single-select persona cards (runtime already uses exactly one card per turn; mutual exclusion would cost v1.2 multi-card its point). * fix(persona): drop stale preview responses and label the fallback honestly (#497 review) Two review findings, both verified against the code before acting. loadPreview wrote injectedPreview without checking which request the response belonged to, and load() wrote the same state a second time. Switching card A to card B could leave A's text on screen while B is being edited — on a card titled "injected text", showing another card's content is worse than showing nothing. The preview now has a single owner plus a sequence guard that discards stale responses, and the panel guard locks both (call-site count and the guard itself). source "default" had two different causes collapsed into one label. With ?agent=<identity> the identity did resolve; it just has no usable card, which is precisely what someone who switched a card off wants to confirm. The panel now splits that from "no identity could be resolved this frame" using the echoed agent, with a backend test asserting the field for both paths. * feat(profile): draft the user profile from memory on demand (#497) The profile card only ever had a pen on it: whatever the store accumulated never came back as a view of the user. This adds the other direction — read the active memories, spend one host-LLM call, return an "as the assistant sees them" draft. Three edges are hard requirements, not preferences. The module never receives `settings` at all: the draft is applied by an explicit panel action that PUTs /profile, because profile prose is hand-written and letting the model "merge" it hands it rewrite rights over text injected every turn. An empty store is refused before the call — a model inventing "she loves learning" from nothing is worse than no draft, since that draft becomes the first version of the user the person sees about themselves. Output that is not the required JSON object is an error, never an empty draft; no-input, unparseable and a dead stream are three distinct HTTP outcomes so the panel can say three different sentences instead of reporting a fault as an empty result (#489's lesson). Memory text is model-influenceable input, so rows go in inside a fence with the role restated in the system turn (same stance as #493's transcript fence), and the system turn forbids naming or personifying the assistant: profile and rules are not governed by personaEnabled nor by card addressing, so a "you are X" line in the profile would re-run the #497 identity collision in every session.

Policy is `token`, not `token-write`: the route has no read branch (non- POST is 405 before readBody — after it, a bodyless method wedges on the read), and declaring a read-open branch would have slipped past SECURITY.md's open-read list, which test/security-doc.test.js exists to catch. Off by default and in LIGHT_MODE_OFF. * fix(profile): verify saves, name the missing-model case, and correct documented codes (#497 review) Three review findings, all verified in code before acting. The profile saver never checked the response: apiFetch is a thin fetch wrapper, so a 403 or 413 still flashed "profile saved" — the persona saver on the same page has always checked res.ok, so this was an outlier, not a convention. It now returns whether the write landed, and applying a draft commits panel state only after that answer, so a failed save keeps both the editor text and the draft instead of leaving the draft cleared with the old profile still stored. resolveRoute returns undefined when neither dreamProvider/dreamModel nor the host default can be resolved; the extractor then read route.provider and threw a TypeError that the route reported as a generic 500. It is a distinct outcome — no-route — mapped to 503 and given its own actionable panel sentence ("pick a model first"), because "the environment lacks a model" and "the model misbehaved" must not share one line of text. The CHANGELOG enumerated the HTTP outcomes as 409/409/502, which is wrong for both ordering and completeness: no-input is 409, no-route 503, unparseable and stream-failed 502, unexpected 500. Documented codes are what callers implement against, so the prose now matches the mapping, and "模型挂了" is gone.

这个 PR 在修什么
src/pipeline-nudge.js从 v0.9.1 起就完整实现了「多帧 zstd 解压 → 重复动作挖掘 → 缺席对照 → draft 草稿」，测试也有 39 个用例。但它在运行时没有任何调用点——全仓引用只出现在test/pipeline-nudge.test.js里。也就是说：机器挖得出来，却永远不会被叫去挖。这就是「M.O. 不能自动沉淀工作流」的直接原因。缺的从来不是算法。
缺的是两件事：归属与触发
归属。
nudgeFromSessions要的是一个项目自己的会话桶目录（<DSH_HOME>/sessions/<工作区桶>），而桶名是路径的有损变形——规则不在本仓，不可反解。唯一可信来源是会话日志头里的cwd。这里有一个必须说清的取舍：查不到归属时整跑跳过，不降级成全局普查。降级看起来更「有用」，但后果是把 A 项目的动作算到 B 头上，而输出的提议长得完全正常——这种错比直接报错难查一个数量级。
触发。 新文件
src/pipeline-nudge-auto.js挂turn/end，那根链上还挂着摘要与续期，所以它：setTimeout(0)宏任务warn，不冒泡session/event链上还有别人的活，一个挖掘器不能把它带崩它只产提议，不产草稿。 自动跑恒
materialize:false，产物落<memoryDir>/proposals/<项目键>/；升格进仓库仍然要人批。boundaries里那句autoActivate:false与「跳过」分支共用同一个常量NUDGE_BOUNDARIES——两条出口说两句不同的话，读的人就会以为其中一条忘了做。顺带修掉一个真 bug
nudgeFromSessions原本只要算得出项目键就无条件落盘提议，跟materialize无关。而面板每刷一次就 GET 一次——那等于每刷新一次往记忆库里塞一批文件。抽出
persistProposals开关，预览路由显式传false。这也是新路由/nudge的 policy 是token-write而不是open的原因：GET/HEAD 免 token（只看不写），POST 要 token（会写盘）。端点的两种「没有」
resolveProjectSessionDir的四种reason里，unreadable（读不到）必须与no-bucket（确实没有）分开：no-sessions-dir/unreadable→ 503，这是故障；no-bucket/bad-project→ 200 +skipped:true，这是关于这个项目的答案。混起来等于把故障报成空结果。面板上 "没挖到新的重复动作" 和 "日志读不出来" 若长得一样，人只能瞎猜。
面板
M.O. 面板多了「现在沉淀一次」按钮，走
POST /nudge，与自动跑同一条nudgeForProject，九句回执中英齐全。读不到cwd时按钮禁用——服务端只会回 400，点了必然失败的按钮比没有按钮更糟。禁用态用虚线边而不是降opacity（会把文字一起压到 AA 以下，有contrast.test.js守着）。术语统一
M.O.（Modus Operandi）从 v0.9.0 起在正文里写作「手法」，而同一个功能在其余位置叫「工作流 / workflow / pipelines」。一个功能两个名字，读者得先猜它们是不是一回事。本次统一改回「工作流」：src 24 处、面板 3 处、文档 11 处。
两处故意不改：已发版的 CHANGELOG 条目（历史不追溯），和
test/release-docs.test.js里那 9 个「手法」——那是夹具主题词，锁的是 README 路线图插入逻辑，动了等于换掉测试对象。旗标
actionNudgeEnabled，默认关，进LIGHT_MODE_OFF。与「看图」（actionPipelineEnabled）、「记账」（actionRunEnabled）是三件独立能力，开任何一个不会顺带开另一个。验证
npm run sync→ 74 filesnpm test→ 2243 tests / 2242 pass / 0 fail / 1 skippednode scripts/check-sync.js→ ✓ 74 个文件平价test/pipeline-nudge-auto.test.js9 用例；test/pipeline-nudge.test.js新增 3 个nudgeForProject用例（归属失败跳过 / 命中 /persistProposals:false不写盘）已知缺口
自动沉淀的效果没有在真实会话里观测过。干净环境和命中两条路都有测试覆盖，但「真跑几轮之后挖出来的提议像不像话」得有真实用量才知道。若产物偏水，调
NUDGE_MIN_SUPPORT（现为 2）比调其他参数更直接。Summary by CodeRabbit
