feat(mo): R1/R2 落地——跳过有了性质，前置违规与 tool 过时都有了提议 by modusensus · Pull Request #454 · slow-stack/mneme

modusensus · 2026-10-17T05:38:14Z

这是什么

M.O. 的 R1/R2 + P3 投影（四项已由维护者拍板"按助手续号"，拍板记录在 PR #452 讨论）。3 提交，2103 测试全绿。

四项落地

拍板	实现
① `RETIRE_AFTER_SKIPS` 语义改	可选步骤被跳 → 只发 `optional-skip-ok` 信息项，绝不提议删；必经被跳 → `drop-step` 与 `rework-path` 并存（同一事实两种读法，谁也不吞谁）
② `optional` 缺省=必经	`validatePipeline` 校验（照 gate 模式）+ 归一化显式落键；存量步骤表零改动
③ R1 违规一次就报	`violation-precedence`：跨整本账本逐 run 查（保住 run 边界），按 run\|step\|need 去重，断在哪条边报哪条
④ P3 投影随 R2 接	`readPipelineDoc` 加 `observationsById`（调用方预读传入，pipeline.js 保持零文件系统职责）+ `fix-step-tool` 提议

retirementProposals 的封闭问题表从 2 类穷举到 5 类（新类不配问法会落进不相关的岔路问法）。

数据链

confirm 写账+旁挂 → /pipeline 读旁挂（loadObservationsById 批量读，末条即最近确认）→ 四类提议 → 面板 doc.suggestions。

隐私不变：观察行只有 {key, count, flags?}（P3 时加的第二道闸），回执与提议都不含命令原文。

过程中一个值得记录的坑

写 drop-step 新逻辑时，07 号文的「if/else 吞并」教训以新形状重演：外层 if 吃掉 skipped>=3 后，else if 里再判同条件恒假——drop-step 永远发不出来。被自己的测试当场抓住，修法后新语义恰好要求两种读法并存。教训已写进提交信息：凡"多类提议"，先写并存测试再写分支。

验证

2103 / 2102 pass / 0 fail / 1 skipped（基线 2080 → +23）
check-sync 72 文件一致；隐私扫描 clean；无 AI 署名
新增 test/pipeline-r1r2.test.js 10 条（四类互不吞并/并存/一次就报/零回归），更新 5 条旧断言到新语义（白名单锁 14→15 键）

已知边界

面板对四类提议的 UI 区分未做（数据已在 doc.suggestions，UI 是下一刀——lib-only 大文件，走效果图复验流程）
跨 run 前置未建模（R1 只查同一条 run 内的缺失；15 号文 §5 有记录）

Summary by CodeRabbit

新功能
- 工作流建议现在可识别前置步骤违规，并根据必经或可选步骤的跳过情况提供不同建议。
- 结合近期观察提示可能不匹配的工具声明；不同类型的建议提供对应问题、选项和答案写入位置。观察数据不可用时，工作流仍可正常显示。
- 步骤可标记为可选。
文档
- README 中的测试数量及本地开发命令示例已更新为 2103。

维护者已拍板四项（按助手续号①改 RETIRE_AFTER_SKIPS ②optional 缺省=必经 ③R1 违规一次就报 ④P3 投影随 R2 一起接），本刀全部实现。 ## R2 声明层步骤新增 optional 布尔，**缺省 false（=必经）**——显式落键而非缺省缺键：「这步可不可跳」是判据要读的语义，读侧拿到的一律是布尔。校验：只能是布尔（照 gate/assert 模式）。存量步骤表零改动（没写就是必经，与旧行为一致）。 ## R1：前置违规（violation-precedence）某步 done 而其 needs 前置在同一条 run 里既非 done 也非 skipped → 提议。 **跨整本账本逐 run 查**（保住 run 边界，tallyRuns 已把它抹掉），按 run|step|need 去重，同一步对不同前置各报一条（修图的人要知道断在哪条边上）。一次就报。 ## R2 判据层：RETIRE_AFTER_SKIPS 的语义按拍板改可选步骤被跳再多次 → 只发 optional-skip-ok 信息项，**绝不提议删** 必经步骤被跳 ≥3 次且从未 uses → drop-step 与 rework-path **并存** （同一事实「必经的一步总被跳」两种读法都给人，谁也不吞谁） 07 号文的教训（if/else 吞并）在这里差点重演——第一版 drop-step 挂在 else if 分支里永远到不了，被自己的测试抓出来。修法后测试断言同步更新。 ## P3 投影 readPipelineDoc 新增 observationsById 参数（调用方用 loadObservations 预读后传入 ——pipeline.js 保持零文件系统职责，旁挂路径规则归 observations 模块管）； suggestRetirements 收 observed 后加 fix-step-tool：确认做过 N 次 + 声明 tool 在最近观察中未出现 → 提议核对（多锚点任一命中即对上；optional/无 tool/未确认不进判据）。 retirementProposals 的封闭问题表从两类**穷举到五类**（含 optional-skip-ok 的信息项问法）——新类不配问法会落进「岔路」那条不相关问法。 ## 测试新增 pipeline-r1r2.test.js 10 条（四类互不吞并/并存/一次就报/零回归）；更新 5 条旧断言到新语义（白名单锁 14→15 键、kinds 并存、nudge 双提议）。基线 2080 → 2103，全量 2103/2102 pass/0 fail，check-sync 72 文件一致。

readPipelineDoc 的 observationsById 参数在上一刀已备好但没人喂。本刀接上： /pipeline 端点读 <memoryDir>/observations/<项目键>/ 下各工作流的旁挂 → 压成 { id: { latest: { activities } } } 传给 readPipelineDoc → suggestRetirements 的 fix-step-tool 从此有真实数据为此给 observations 模块补了批量读 loadObservationsById（单工作流的 loadObservations 保留原样）：末条记录即最近一次确认，没有观察的 id 不进结果——读侧 `?? null` 降级，不制造空壳。接线纪律与 /candidates 同款：memoryDir 同源同默认；读旁挂失败 try/catch 降级成「没有观察」——旁挂是可再生的辅助数据，不能连累图（与 P2 时「旁挂写失败不连累记账」是同一条纪律的读侧半边）。全量 2103/2102 pass/0 fail（无新增测试：端点接的是既有函数的组合，数据形状由 observations 模块的 10 条锁守着）。

📝 Walkthrough

流水线退休建议现在区分必经步骤与可选步骤，并检查运行记录中的前置依赖和工具观察数据。项目级 /pipeline 路由会加载对应观察数据。README 中的测试数量由 2080 更新为 2103。

Changes: 流水线退休建议

Layer / File(s)	Summary
步骤契约与退休规则 `dsh-mneme/lib/pipeline.js`, `dsh-mneme/src/pipeline.js`, `dsh-mneme/test/pipeline-r1r2.test.js`, `dsh-mneme/test/pipeline.test.js`, `dsh-mneme/test/pipeline-runs.test.js`	步骤新增 `optional` 布尔字段，缺省时归一为 `false`。必经步骤连续被跳过至少三次时会产生 `rework-path`；只有从未使用的必经步骤还会产生 `drop-step`。可选步骤达到跳过阈值时产生 `optional-skip-ok`。建议计算还会报告运行内缺失的前置依赖，并在声明工具与观察活动不匹配时产生 `fix-step-tool`。
观察数据读取与传递 `dsh-mneme/lib/pipeline-observations.js`, `dsh-mneme/src/pipeline-observations.js`, `dsh-mneme/lib/pipeline.js`, `dsh-mneme/src/pipeline.js`, `dsh-mneme/lib/api.js`, `dsh-mneme/src/api.js`	新增 `loadObservationsById`，按流水线 ID 返回最新记录的活动和不可读行数。项目级 `/pipeline` 路由按运行账本 ID 加载观察数据，并传给 `readPipelineDoc`；观察目录缺失或读取失败时使用空映射。
建议类型问答配置 `dsh-mneme/lib/pipeline-nudge.js`, `dsh-mneme/src/pipeline-nudge.js`, `dsh-mneme/test/pipeline-nudge.test.js`	`retirementProposals` 为五种建议类型分别配置问题、选项和写入位置。未映射类型使用通用问题、“不知道”选项及新版本步骤写入位置。

README 测试数量

Layer / File(s)	Summary
更新 README 测试数量 `README.md`, `dsh-mneme/README.md`	中文和英文 README 中的测试徽章、架构说明和本地开发命令示例，将测试数量从 2080 更新为 2103。

Merge Risk: 🟡 Moderate · up to 5eb0d

Project pipeline requests cannot use recorded observations to identify tool mismatches. Fix the ID scope in both handlers before merging.

Security architecture risk: 🔵 Low · up to 5eb0d

The reviewed changes produce advice rather than execute tools or modify pipeline definitions. No introduced security vulnerability was established. The intended activity-data response is currently blocked by a scope error, while deployed endpoint access and local storage permissions remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

observed — The reviewed suggestion and proposal functions construct data only. They do not execute declared tools, invoke agents, or apply changes to pipeline definitions. Their writeTo values describe proposed human-approved changes rather than granting write authority.

Trust Boundaries and Controls

observed — Existing observation writing derives a project bucket from a sanitized project name and path hash, uses the confirmed pipeline ID, and copies only key, count, and optional flags into activity records. It rejects command, args, and segments fields. Upstream normalization restricts verbs and token shapes, but these controls do not authenticate a caller or establish filesystem ownership.
observed — The existing pipeline route accepts caller-supplied absolute project paths and does not invoke requireAuth. That route behavior predates this PR. The new observation-loading attempt does not establish additional HTTP data exposure at the reviewed head because it fails before invoking the loader; host-level authorization and network reachability remain unknown.

Resilience and Maintainability Implications

inferred — The batch reader interprets physical record order as recency. The unchanged writer performs duplicate detection before appending without a cross-process lock, so concurrent or out-of-order writes do not guarantee chronological or unique records. This can affect advisory accuracy, but no resulting execution authority or security-control bypass was established.

Hardening Proposals

proposed — Before making observation-derived HTTP output operational, validate loaded record identity and activity contents at the read boundary and explicitly confirm which callers may receive project activity metadata. Treat this as hardening, not as a verified vulnerability in the current flow.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

ids 的块级作用域导致观察数据加载必定失败。 ids 用 const 声明在 if (project !== null) 块内，但在块外被读取。读取时抛出 ReferenceError，空 catch 吞掉这个异常，所以 observationsById 恒为 {}。fix-step-tool 因此在 /pipeline 上永远不出现。

dsh-mneme/src/api.js#L1754-L1754：在 runsResult 旁声明 let ids = [];，把 Line 1718 的 const ids = 改为 ids =。

dsh-mneme/lib/api.js#L1754-L1754：做同样的修改，保持与 src 同步。
