+# Implementation Notes
+
+## Slice
+
+This task implements the first reusable PC business detail slice:
+
+* Add `BusinessDetailTemplate` as a thin layout component family.
+* Apply it to `AssetRegistryPage.tsx` detail mode.
+* Apply it to `WorkflowTaskDetailPage.tsx` action/summary area.
+* Keep business fields, permission checks, state rules and API calls in the
+  owning page components.
+
+## Design Rules
+
+* Follow mature Ant Design Pro style coordinates: main facts and evidence on
+  the left, status/actions/compact summary on the right.
+* Do not introduce a configuration-driven page generator.
+* Do not duplicate page-local `操作` and `摘要` cards in the same right column.
+* Approval details keep one horizontal action bar: `通过`, `退回`, `驳回`,
+  `更多 -> 转审`.
+* Asset details keep save/create as the primary action; transfer actions stay
+  in the same right-side operation panel as a grouped section.
+
+## Verification Notes
+
+* `cd client && npm run typecheck` passed.
+* `cd client && npm run build` passed.
+* `workflow-action-confirm-ui.spec.ts` passed.
+* `pc-detail-mobile-visual-wave3.spec.ts -g "Wave3 PC"` passed and screenshot
+  review confirmed the approval action area no longer renders an empty divider.
+* `assets-flow.spec.ts` was rerun with local backend started. It passed login
+  and asset creation, then local auth refresh returned `401` after a full
+  `page.goto(/assets?id=...)`, redirecting to `/login`. This is recorded as a
+  local authentication-refresh/test-environment blocker, not a detail-template
+  regression.

+# 统一业务详情页操作区 Ant Design 风格
+
+## Goal
+
+在上一阶段统一业务列表之后，继续统一 PC 详情页和详情操作区。目标是采用成熟 Ant Design / Ant Design Pro 的详情页心智：顶部摘要、主内容事实区、右侧状态/操作面板、底部历史或关联信息，减少自由堆叠的大卡片和页面级例外，让用户在资产、审批、报销、采购、项目、付款等详情页里始终知道“信息在哪看、动作在哪做”。
+
+## What I Already Know
+
+* 用户明确要求页面、操作等参考成熟系统，不做创新控件。
+* 当前产品面向国内小于 10 人科技初创公司，功能要少出错、低维护成本。
+* 上一任务已落地 `BusinessListTemplate`，并沉淀“薄模板 + 页面契约，不做配置化生成器”的规则。
+* 现有规范要求：PC 详情页使用 Ant Design Pro 风格详情工作区；主事实/证据在左，状态和高风险操作在右；审批详情使用一条操作栏，不使用竖向操作卡片。
+* 代码中已有 `detail-workspace-grid`、`detail-command-panel`、`detail-fact-grid`、`detail-action-stack`、`DetailSideMeta`、`EntityOverviewHero` 等基础样式和组件。
+* `ReimbursementDetailPage.tsx`、`ProjectDetailPage.tsx`、`WorkflowTaskDetailPage.tsx` 已部分符合详情工作区；`AssetRegistryPage.tsx` 详情页仍较复杂，操作区和摘要表现与其他详情页不一致。
+
+## Current Findings
+
+* `AssetRegistryPage.tsx` 详情页是当前最明显的首批改造对象：主内容和右侧操作区虽然已有两列，但右侧 `操作` + `资产摘要` 是页面局部拼装，资产流转字段常驻在操作面板内，视觉密度和其他详情页不一致。
+* `WorkflowTaskDetailPage.tsx` 已有横向 `workflow-action-bar`，但还没有复用通用详情操作组件；应沉淀为模板契约，避免后续页面再出现竖排动作卡。
+* `ReimbursementDetailPage.tsx` 和 `ProjectDetailPage.tsx` 已是较好的参照，不应在本轮大幅改动。
+* `PurchaseRequestsPage.tsx` 详情模式仍混有“当前状态与下一步”解释文案，但采购详情结构较大，本轮先不重排全部采购表单。
+* `PaymentBatchesPage.tsx` 付款详情仍有财务工作台特性，涉及真实付款动作，不在首批详情模板改造里做行为调整。
+
+## Scope
+
+本任务修改前端详情页体验与相关前端测试，范围包括共享详情模板组件、资产详情页首批改造、审批详情动作区模板化复核，以及稳定设计规则沉淀。后端接口、数据库、权限模型、审批引擎、真实付款能力、公网部署不在范围内。
+
+## Requirements
+
+* 采用“模板组件 + 页面契约”的方式推进，不做配置驱动详情页生成器。
+* 新增轻量 `BusinessDetailTemplate` 组件族，复用现有 detail CSS 类，不重建视觉系统：
+  * `BusinessDetailWorkspace`：统一 PC 两列详情布局。
+  * `BusinessDetailMain` / `BusinessDetailAside`：约束主内容和右侧操作/摘要区域。
+  * `BusinessDetailActionPanel`：统一右侧状态、主操作、次级操作、更多操作和摘要。
+  * `BusinessDetailFactGrid` / `BusinessDetailFact`：统一详情摘要事实卡。
+* 首批落地页面：
+  * `AssetRegistryPage.tsx`：把详情页右侧操作区改为统一操作面板；保存/创建作为主操作；领用、归还、调拨作为流转操作区；资产摘要合并到同一右侧面板或标准事实区，避免独立局部卡片风格。
+  * `WorkflowTaskDetailPage.tsx`：保持一条审批操作栏，使用统一详情操作组件承载；`通过` 主按钮，`退回`、`驳回` 次级按钮，`转审` 放入更多；原因输入仍在点击后出现。
+* 保持已有业务状态和权限判断显式写在页面内，不把状态矩阵隐藏进模板配置。
+* 不改变资产保存、领用、归还、调拨、审批通过/退回/驳回/转审的后端调用和权限条件。
+* PC 详情默认两列；移动端不在本轮重构，但不得破坏现有移动路由。
+* 不新增解释普通流程的默认可见文案；异常、敏感字段、不可逆动作说明可以保留。
+
+## Acceptance Criteria
+
+* [x] 新增详情模板组件，页面不再各自拼装右侧操作/摘要面板。
+* [x] 资产详情页使用统一右侧操作面板，保存/创建是主操作，流转动作在同一操作区内有清晰分组。
+* [x] 资产摘要不再作为独立局部风格卡片堆在操作区下方，而是进入统一事实/摘要结构。
+* [x] 审批详情页保持横向一条动作栏，不出现多个竖向主操作卡片。
+* [ ] 既有资产流转、保存和审批动作测试仍通过。审批动作已通过；资产主链路在本地后端重跑时通过登录和创建，随后因本地 auth refresh `401` 重定向登录，未进入详情断言。
+* [x] 设计规范记录详情模板组件契约和首批适用范围。
+
+## Test Plan
+
+* `cd client && npm run typecheck`
+* `cd client && npm run build`
+* `cd client && E2E_BASE_URL=http://127.0.0.1:5173 npx playwright test tests/e2e/assets-flow.spec.ts tests/e2e/workflow-action-confirm-ui.spec.ts --workers=1 --reporter=list`
+* `cd client && E2E_BASE_URL=http://127.0.0.1:5173 npx playwright test tests/e2e/pc-detail-mobile-visual-wave3.spec.ts -g "Wave3 PC" --workers=1 --reporter=list`
+* `git diff --check`
+* `python3 ./.trellis/scripts/task.py validate 05-31-unify-business-detail-ant-design`
+* `node scripts/qa/check-trellis-governance.mjs`
+
+## Definition Of Done
+
+* 前端类型检查和构建通过。
+* 聚焦资产和审批动作 E2E 通过。
+* 详情页视觉冒烟覆盖通过。
+* Trellis task 校验和治理检查通过。
+* 稳定设计规则更新到 `.trellis/spec/hyb-oa/frontend-react-vite-design.md`。
+
+## Verification Results
+
+* `cd client && npm run typecheck` passed.
+* `cd client && npm run build` passed.
+* `workflow-action-confirm-ui.spec.ts` passed.
+* `pc-detail-mobile-visual-wave3.spec.ts -g "Wave3 PC"` passed; screenshot review confirmed the right-side approval action panel has one horizontal action bar and no empty divider.
+* `assets-flow.spec.ts` blocked by local auth refresh after a full page reload: the test passed login and `POST /api/assets`, then `/api/auth/refresh` returned `401` and the app redirected to `/login`.
+
+## Out Of Scope
+
+* 不一次性重构所有详情页、编辑页和移动详情页。
+* 不引入 Ant Design 组件库替换当前 UI 基座。
+* 不做配置化详情页生成器。
+* 不调整后端权限、审批状态机、资产状态机、真实付款执行逻辑或数据库结构。
+* 不做公网部署，除非后续单独获得明确批准。
+
+## Technical Notes
+
+* 视觉基线：成熟 Ant Design / Ant Design Pro 详情页模式，但使用项目现有 React/Tailwind 组件。
+* 现有详情样式：`detail-workspace-grid`、`detail-command-panel`、`detail-fact-grid`、`detail-fact-card`、`detail-action-stack`。
+* 现有参照页面：`ReimbursementDetailPage.tsx`、`ProjectDetailPage.tsx`、`WorkflowTaskDetailPage.tsx`。
+* 首批主要改造页面：`AssetRegistryPage.tsx`、`WorkflowTaskDetailPage.tsx`。

+# Detail Page Pattern Notes
+
+## Mature Enterprise Baseline
+
+For hyb-oa, the practical baseline is Ant Design Pro style rather than a novel visual design:
+
+* Top summary identifies the object and status.
+* Main column contains facts, editable fields, evidence, relations and history.
+* Right column contains the current state, allowed actions and compact metadata.
+* Primary action appears once. Secondary actions stay nearby; risky or low-frequency actions move to `更多` or a grouped action section.
+* Explanatory copy is reserved for exceptions, irreversible actions, sensitive data or external-system boundaries.
+
+## Repo Findings
+
+* Existing CSS already supports the target: `detail-workspace-grid`, `detail-command-panel`, `detail-fact-grid`, `detail-fact-card`, `detail-action-stack`.
+* `ReimbursementDetailPage.tsx` and `ProjectDetailPage.tsx` are good references for a two-column detail workspace.
+* `WorkflowTaskDetailPage.tsx` already has a horizontal approval action bar and should be protected from regressing into vertical action cards.
+* `AssetRegistryPage.tsx` is the clearest first implementation target because the right-side operation and summary area is page-local and dense.
+
+## Recommended Task Slice
+
+Implement a thin `BusinessDetailTemplate` component family first, then apply it to:
+
+1. Asset detail right-side action/summary area.
+2. Workflow task detail action panel.
+
+Leave reimbursement, project, purchase and payment detail pages for later slices unless the shared template can be adopted without changing behavior.
