+# 增量 C 前端独立评审（W10 审计工作台 + 依据/候选确认路径）
+
+- 评审对象：`feature/rdm-two-trees-followup-w10` @ `fa08be4`（基线 `ec1ced3`，dev 无本地改动）
+- 范围：`src/components/RdmAuditWorkspace.tsx(+test)`、`Conversation.tsx`、`ConversationWork.tsx`、`Workbench.tsx`、`src/api.ts`、`src/styles.css`、`src/companion-conversation.css`、`e2e/rdm-audit.playwright.ts`
+- 增量：`+1048 / -7`，9 文件（`git diff --stat ec1ced3 fa08be4`）
+- 评审性质：只读评审。代码零改动；本文件是唯一写入。契约核对基线：RDM 侧 `Agent-System-RDM-wt-feature-rdm-two-trees-followup-c-w8-w10` @ `c4c6df7`（本地检出的 W8b/W5 命令面）；计划基线：`modules/documents` `rdm-two-trees-stage5-implementation-test-plan-r1.md` §W10
+- 环境限制：本仓为独立检出，组合仓 `../ui`（`@ui` 源码别名）缺失、子模块未初始化 ⇒ 依赖 `@ui` 的 22 个测试文件与 `tsc -b` 无法在本工作区运行（见 §验证）。`npm ci --offline` 可用，故守护测试与 knip 实跑。
+
+## 1. 逐项结论
+
+| # | 检查项 | 结论 | 依据 |
+|---|---|---|---|
+| 1 | 设计门禁（令牌/动效/折叠） | **FAIL（部分）** | 裸色值、私有 keyframes、行内字号、`transition`、`--fs-ui-*` 全部通过守护测试（7/7 PASS）；但两处折叠未用 `@ui Collapsible`（MAJOR-3） |
+| 2 | DTO 边界（只消费服务端已裁剪 DTO、无新增全量拉取） | **PASS** | 页面只渲染 `display/recorded/disclosure`；服务端 `redactOperationBodies`（`inspection_visibility.go:70-88`）确实把无权正文的 `summary.display` 换成「受限」并清空 `object.current`，前端未越权补正文；列表单页 `limit:30`，证据/影响分析均为按需单条读取，无全量拉取 |
+| 3 | 异步纪律（单一 owner、seq 丢迟到响应） | **PASS（有 1 处冗余镜像，见 MINOR-4）** | `createOperationsFeed` 每请求取 `++seq`，非最新 seq 的成功与失败一并丢弃，`dispose()` 亦作废在途；续页回传首页 `cutoffSeq`；其余面板沿用既有 `startLatestFetch` 单 owner 模式 |
+| 4 | 四态可读 + 游标失效显式 | **PASS** | 加载/空/错误（denied·cursor·query·capability·auth 分流）/旧记录「当时未记录」/正文受限/部分覆盖/影响截断均有独立文案；错误分类正则与服务端真实串一致（`权限拒绝：…` 出自 `perms_api.go:234`；`操作记录游标已失效…` 出自 `operation_projection.go:42`），非臆测匹配 |
+| 5 | 既有行为兼容（树/卡片/对话/导出预览；右栏收起的确认路径） | **FAIL** | 树/卡片/对话/导出预览无回归（页签按名定位，`审计记录` 与既有 `操作记录` 不冲突，`.rdm-audit-card` 计数断言互不干扰）；但右栏收起后的「对话确认路径」在最需要它的工作卡场景下是空操作（MAJOR-1） |
+| 6 | e2e 扩展质量（skip 如实） | **PASS（附 MINOR-6）** | `test.skip(!SVC_REAL_RDM_BIN, …)` 与注释如实说明「缺真实 RDM 二进制则整组跳过、不伪造」；但当前 CI 与 Dev `scripts/e2e.sh` 均不注入该变量 ⇒ 4 条新用例在任何现有执行入口下都永不运行（零证据） |
+| 7 | 知识多挂载为 TODO 未实现、未虚报 | **PASS（附 MINOR-7）** | `RdmAuditWorkspace.tsx:591` 仅留 TODO，未见任何实现或「已完成」表述；TODO 给出的理由经核实为真：W8b 分支 RDM 侧 `grep '"mounts"'` 零命中，`rdm.inspect.tree/object` 确实无挂载字段（域层已有 `MountsOf`，仅未出 DTO） |
+
+## 2. BLOCKING
+
+无。
+
+## 3. MAJOR
+
+### MAJOR-1 右栏收起后的「对话确认路径」在目标场景下是空操作（承诺与实现不符）
+
+- 位置：`src/components/Conversation.tsx:571-572, 734-740`；关联 `src/components/ConversationWork.tsx:65, 91`；承诺文案 `src/components/Workbench.tsx:82`
+- 理由：新提示条仅做 DOM 定位滚动：
+  `body.querySelector('[data-card-id="…"]') ?? body.querySelector('[data-conversation-work]')`。
+  但显示条件恰是 `!workPaneOwnsCards`（右栏收起或非工作页签），此时：
+  1. `ConversationWork` 命中 `if (!detailHere) return null`（`ConversationWork.tsx:91`）——`[data-conversation-work]` 整个子树不存在；
+  2. 工作卡在对话正文里只经 `CardAnchor` 出现，而 `Conversation.tsx:56` 对带 `card.work` 的卡显式传 `card={undefined}`，UI 侧 `data-card-id={card?.id}`（`modules/ui/src/CardAnchor.tsx:25`）因此不落属性。
+  结果：W10 重点场景（候选工作卡待确认）点「N 项待你确认 · 在对话中处理 ↓」→ `target` 为 `null` → `target?.scrollIntoView` 静默无动作，而收起按钮的 title 却承诺「N 项待确认会在对话中继续处理」。
+  附带：`pendingHere`（含 `work.decision.state === 'open'`）与 `pendingCardId`（仅 `status === 'action_required'`，`Conversation.tsx:572`）口径不同，decision-open 卡即使能定位也算不出 `id`。
+- 修复建议：改走仓内既有的唯一定位路径 `store.openInbox(pendingCardId)`（`src/store.ts:1625-1633`：展开右栏、切工作页签、`flashLocate('.right-panel','data-card-id',…)`），或在 `!workPaneOwnsCards` 时把候选/决议控件渲染进对话正文；同时让 `pendingCardId` 与 `pendingConfirmations` 用同一谓词。
+
+### MAJOR-2 新增「审计记录」页签无能力门禁，缺命令面的构建上恒为错误态
+
+- 位置：`src/components/RdmAuditWorkspace.tsx:52, 125-137`
+- 理由：页签无条件挂载，而仓内既有约定是「能力缺失即不暴露」（`src/store.ts:1462-1475` 依 `api.listCommands()` 刷新能力位；`src/workspaces.ts:52` `rdmAuditReady`）。当前就绪门 `RDM_AUDIT_COMMANDS` 只含 7 个 `rdm.inspect.*`（`workspaces.ts:23-31`），不含 W8b/W5 的 `rdm.audit.operations`、`rdm.trace.coverage`、`rdm.trace.pending-recheck`、`rdm.compliance.impact.*`。因此在已合入的 RDM 上审计工作区入口照常可见，而新页签必然落到 `classifyOperationsError → capability`（「当前服务未提供审计能力」），与 `e2e/plain-base.playwright.ts:38-51` 记录的「零暴露、不进入即 400」原则相悖。
+- 修复建议：在 `workspaces.ts` 增加 `rdmAuditOperationsReady(cmds)`（上述 5 条命令）并在页签列表按能力过滤；覆盖面板与影响分析入口同样受此门控；若坚持常显，则须在 PR 描述中登记为已知降级并由 RDM 发布节奏兜底。
+
+### MAJOR-3 两处折叠未使用 `@ui Collapsible`（违反 DESIGN.md §9.2）
+
+- 位置：`src/components/RdmAuditWorkspace.tsx:1200`（`EvidenceLink`）、`:1266`（`ImpactAnalysisBlock`）
+- 理由：两者用 `<button aria-expanded>` + 条件挂载自建展开，未消费全项目唯一折叠原语；DESIGN.md §9.2「一切折叠区…用它：外壳高度动画 + 内容 fade 两层分离、300ms 延迟卸载、展开态记忆」。守护测试只拦 `<details>`，故测试全绿但违宪——本次评审门禁「折叠只用 @ui Collapsible」据此判 FAIL。
+- 修复建议：改为 `<Collapsible id={…} trigger={…}>`（这两处都有稳定的 id 语义：证据 `${pid}/${kind}/${id}`、影响分析 `${pid}/${analysisId}`），可顺带获得展开态记忆与卸载动画。若以「同文件 `:408`、`RegCitation.tsx:157` 已有先例」为由豁免，请在 PR 中显式登记豁免理由，而非默认放行。
+
+## 4. MINOR
+
+| # | 位置 | 问题 | 建议 |
+|---|---|---|---|
+| MINOR-1 | `src/components/ConversationWork.tsx:22-24` | `candidateActions` 未排除已有决议表单的卡：@ui `WorkCardBody` 对 `work.decision` 开放态渲染 `DecisionForm`，若该卡 `actions` 同时含 confirm/reject，则同一决议出现两个入口，且新按钮只提交 `{resultVersion}`（不含 `selectedIds`/`freeText`），存在「未选选项即提交」风险 | 首行加 `if (card.work?.decision?.state === 'open') return []`，保持一个动作一个入口 |
+| MINOR-2 | `src/components/Workbench.tsx:38-41` | `pendingConfirmations` 与 @ui `pendingCount`（`modules/ui/src/InboxList.tsx:103-106`）口径不一致：新函数未排除 `status === 'resolved'`，「resolved + decision open」的卡会被计入输入区提示与收起提示，却不计入收件箱/顶栏计数 ⇒ 同屏两个数字打架 | 直接复用 `pendingCount` 语义，或在注释中说明差异并统一文案 |
+| MINOR-3 | `src/components/RdmAuditWorkspace.tsx:1303` | 覆盖面板用 `Promise.all([rdmTraceCoverage, rdmTracePendingRecheck])`：任一命令缺失（较旧构建只有 coverage）即整面板降级，正式/候选覆盖数字一并消失 | 改 `Promise.allSettled`，coverage 可用即渲染，pending 不可用时只在待复核一栏给说明 |
+| MINOR-4 | `src/components/RdmAuditWorkspace.tsx:1051, 1060` | `dict` 是 `state.dictionary` 的第二份异步状态镜像；切项目时旧项目词典保留到新页落地，可能把「新项目不存在的筛选值」静默带上，且 `<select>` 无匹配 option 时显示为空白 | 随 `pid` 变化清空 `dict`，或词典未就绪前禁用两个 select |
+| MINOR-5 | `src/components/RdmAuditWorkspace.tsx:1090` | `.rdm-audit-ops` 在任何 CSS 中都无规则（本次只补了 `.rdm-audit-wrap`、`.rdm-audit-op .rdm-audit-opgroup-head/.rdm-audit-op-pending`、`.rdm-audit-op-object`），列表容器无布局约束 | 补一条容器规则或复用既有类名，避免长对象名/窄屏下出现不可预期的块级堆叠 |
+| MINOR-6 | `e2e/rdm-audit.playwright.ts:150` | 整组 skip 条件 `SVC_REAL_RDM_BIN` 在 Dev `scripts/e2e.sh` 与本仓 CI 中均无注入（`grep SVC_REAL_RDM_BIN scripts/e2e.sh` 零命中；CI 只跑 `npm test` + `npm run build`）⇒ 4 条新用例（含游标翻页、游标失效重查、无授权三态）当前零执行证据 | 组合验证时由 e2e.sh 导出该变量（它已在 `$OUT/agent-system-rdm` 构建出二进制，`e2e.sh:88`），或在 PR 中把「e2e 未运行」显式登记为 NOT_RUN 缺口 |
+| MINOR-7 | `src/components/RdmAuditWorkspace.tsx:591` | 知识多挂载降级只以代码 TODO 记录；计划 §W10 把「知识多挂载」列入实施范围（`rdm-two-trees-stage5-implementation-test-plan-r1.md:154`），缺登记的降级记录，容易在跨仓验收时被当作已交付 | 在 Dev 任务卡/证据条目登记该验收项为「待 RDM DTO 增补」，并回指此 TODO；代码内无需再改 |
+
+## 5. 已核实的正面结论（附证据）
+
+1. **DTO 边界真实成立**：`internal/rdmapp/inspection_visibility.go:70-88` 在无权时把 `change.summary.display` 置为「受限」、`disclosure='restricted'`、`object.current=nil`；前端 `OperationRow`（`:1125-1170`）只渲染服务端 `display/recorded`，`refsText` 只拼 `kind.label+id`，未渲染任何前端臆造的正文或补全的「当前」名称。
+2. **契约字段与 RDM 实际 DTO 对齐**：`OperationRecordDTO`/`OperationPage`/`ImpactAnalysis`/`TraceCoverageResult`/`TracePendingEdge` 的 JSON tag 与 `src/api.ts:73-175` 的类型逐字段核对一致（含 `cutoffSeq/nextCursor/total`、`ObjectRef.revision` 为字符串、`CGap{rule,node,reason}`）。
+3. **错误分类与服务端真实串匹配**：`权限拒绝：`（`perms_api.go:234`）→ `denied`；`操作记录游标已失效`（`operation_projection.go:42`）/`操作记录游标不合法`（`:454`）→ `cursor` 且隐藏翻页按钮并给「从第一页重新查询」。
+4. **异步纪律的测试覆盖到位**：`createOperationsFeed` 的 seq、dispose、续页 `cutoffSeq`、迟到失败响应均有断言（`RdmAuditWorkspace.test.tsx:145-215`），且实现与断言一致（`request()` 成功/失败双路都比对 `mine === seq`）。
+5. **未引入 knip 基线压力**：`node scripts/check-knip.mjs` → `knip unused exports 58 <= 58`；逐项核对 knip JSON，本次改动的 5 个文件未新增 unused exports/types。
+6. **既有回归面检查通过**：既有 `操作记录` 页签（TimelineTab）与新 `审计记录` 页签按 aria 名定位互不冲突；既有 e2e 的 `.rdm-audit-card` 计数断言作用于概览页签，与新覆盖卡片不同时渲染；导出预览入口（`exportNeedsDraft`/`DocumentRenderWorkspace`）未改动。
+
+## 6. 验证命令与结果（本工作区实跑）
+
+| 命令 | 结果 |
+|---|---|
+| `git diff --stat ec1ced3 fa08be4` | 9 files, +1048/-7（评审对象确认） |
+| `npm ci --offline --no-audit --no-fund` | 176 packages（仅本地缓存，未联网） |
+| `npx vitest run test/design-guard.test.ts` | **PASS** — Test Files 1 passed, Tests 7 passed（① 门禁实测） |
+| `npx vitest run` | 43 files passed / 22 files failed；398 tests passed, 1 failed。22 个失败文件与该 1 个失败全部为 `Error: Cannot find package '@ui'`（组合仓 `../ui` 未检出），无其他错误类别 |
+| `npx vitest run src/components/RdmAuditWorkspace.test.tsx` | **NOT_RUN** — 同一 `@ui` 解析失败（新增单测在本工作区无法执行） |
+| `npx tsc -b` | **NOT_RUN** — 全部为 `TS2307 Cannot find module '@ui'` 及其引发的隐式 any，无新增类型错误信号 |
+| `node scripts/check-knip.mjs` | **PASS** — `knip unused exports 58 <= 58` |
+| `npm run e2e` / `npx playwright test` | **NOT_RUN** — 无 `PLAYWRIGHT_BASE_URL` 且无浏览器/后端组合环境；`SVC_REAL_RDM_BIN` 未注入时新组按声明跳过 |
+| 浅/深主题、窄屏、长对象名视觉检查 | **NOT_RUN** — 需真实组合浏览器；静态侧只能确认新增样式全部消费令牌 |
+
+## 7. 合入建议
+
+1. **合入门禁**：MAJOR-1、MAJOR-2 建议在合入前修复（前者是承诺失效，后者是能力面 fail-closed 破口）；MAJOR-3 可修或登记豁免。
+2. **证据缺口**：本单元的 vitest/tsc/e2e 在组合检出（`../ui` 就绪 + auth-on 真实 RDM）下必须补跑；在补跑前，本评审对新增单测与 e2e 的结论仅为静态核对，不得记为「测试通过」。
+3. **范围声明**：知识多挂载（MINOR-7）按计划 §W10 属未完成项，验收矩阵中应保持「待 RDM DTO 增补」状态，不得因代码内 TODO 而计为已交付。

weichenandCursor	6e611c5de0	Keep the scratch flag out of the Core-generated contracts governance / governance (pull_request) Successful in 19s Details ci / test-and-build (pull_request) Successful in 49s Details Why: src/contracts.ts is regenerated from Agent-System-Core by the Dev composite; the scratch field added there is dropped on regeneration and tsc then fails in make build. Evidence: contracts.ts equals the Core-generated output; npx tsc -b --noEmit, npx vitest run (685 tests) and check-knip pass locally (SELF). Impact: ConversationView (Conversation & { scratch?: boolean }) in api.ts carries the server-local flag, mirroring the Backend conversationView; no behavior change.

Evidence: npx vitest run (685 tests) and npx tsc -b --noEmit pass locally against the UI fix branch (SELF); CI on the PR head is authoritative. Impact: Scratch conversations hide the cross-read setting, always show the conversation inbox and omit onArchive; real projects are unchanged.

weichenandCursor	1d7f2a3e1b	Add the no-project conversation view backed by scratch sessions governance / governance (pull_request) Successful in 18s Details ci / test-and-build (pull_request) Successful in 3m48s Details Why: Accounts without project.create need isolated general-agent chats. The sidebar groups every scratch session under one "无项目对话" entry instead of the project switcher, and the client no longer auto-creates a default project. Evidence: npx vitest run (64 files, 677 tests) and npx tsc -b --noEmit pass locally (SELF); CI on the PR head is authoritative. Impact: createTask uses POST /api/scratch-sessions in scratch mode or when no real project exists; scratch rows hide cross-read toggles and project settings; "新建项目…" stays gated by project.create.
