+## Scenario: Management Route Metadata And Permission Disclosure
+
+### 1. Scope / Trigger
+
+- Trigger: adding or changing a PC management landing item, management subpage,
+  nested management detail, breadcrumb, sidebar ownership or recent-visit title.
+
+### 2. Signatures
+
+- Registry: `client/src/features/navigation/managementRoutes.ts`.
+- Resolver inputs: `pathname: string` plus the current `permissions: string[]`.
+- Router permissions: `getManagementRoutePermissions(key)`.
+- Recent visits: `writeRecentVisit(path, title, permissions)` and
+  `readRecentVisits(permissions)`.
+
+### 3. Contracts
+
+- The management landing cards, root-navigation permission union, sidebar
+  active state, Topbar title/breadcrumb and recent-visit filtering derive from
+  the same registry entry.
+- React Router keeps explicit component declarations and consumes the same
+  registry permissions. Server authorization remains the hard access boundary;
+  navigation metadata only enforces least disclosure.
+- Match the most specific route deliberately. A nested employee profile must
+  resolve after its exact siblings and must not inherit a broader prefix by
+  accident.
+- A user without the registered permission receives no restricted title,
+  breadcrumb or recent-visit link. Revoked permissions also clean stale local
+  recent-visit records.
+- The sidebar keeps one `管理` root entry. Do not spread low-frequency child
+  pages back into the primary navigation.
+
+### 4. Validation & Error Matrix
+
+- Registered route + allowed permission -> natural Chinese title, parent chain
+  and management sidebar active state.
+- Registered route + denied permission -> no restricted metadata; Router and
+  server guards still reject access.
+- Unknown registry key passed to the Router helper -> throw during development
+  instead of silently using an empty permission list.
+- Newly declared application route missing from the route manifest -> local
+  candidate route gate fails.
+
+### 5. Good/Base/Bad Cases
+
+- Good: `/people/:employeeId` uses the registry for both
+  `管理 / 人员 / 员工档案` and its `system.users` Router guard.
+- Base: `/system/settings` displays only `管理`, with no self-referencing
+  breadcrumb.
+- Bad: add a path to `SystemSettingsPage`, `NavLinks`, `PAGE_TITLES` and Router
+  as four hand-maintained facts.
+
+### 6. Tests Required
+
+- Registry contract covers unique keys, expected path inventory, parents,
+  permissions, landing metadata and root permission derivation.
+- Permission-negative coverage asserts no title/breadcrumb disclosure and
+  filters a previously stored recent visit after permission revocation.
+- Focused Playwright covers direct management deep links, sidebar active state,
+  nested breadcrumbs and the management-root return link.
+- Run `cd client && npm run typecheck && npm run build` and
+  `bash scripts/qa/run-local-candidate.sh list`.
+
+### 7. Wrong vs Correct
+
+#### Wrong
+
+```tsx
+const MANAGEMENT_ACTIVE_PATHS = ["/people", "/system/users"];
+<RequirePermission anyOf={["system.users"]}>...</RequirePermission>
+```
+
+#### Correct
+
+```tsx
+isManagementPath(pathname, permissions);
+<RequirePermission anyOf={getManagementRoutePermissions("people")}>...</RequirePermission>
+```

+# 管理导航闭环与单公司体验收敛设计
+
+## 1. 设计边界
+
+本任务修复管理信息架构的单一事实源和单公司配置体验，不把管理区改造成产品化后台。侧栏继续只有一个「管理」入口；管理首页继续承担低频配置入口聚合。统一层只提供路由元数据、父子关系和导航表达，不接管 React Router 组件装配或服务端权限校验。
+
+## 2. 管理路由注册表
+
+在 `client/src/features/navigation/` 建立共享管理路由注册表。每项建议包含：
+
+- `key`：稳定标识。
+- `path`：可导航地址；详情项可只提供 matcher 和父级。
+- `match`：exact/prefix 或显式匹配规则，避免 `/people` 与 `/people/:id` 标题混淆。
+- `title`：Topbar、面包屑和最近访问使用的自然中文。
+- `parentKey`：父级管理项；顶层配置页父级固定为 management root。
+- `group`、`icon`、`description`、`anyOf`：管理首页卡片的分组、展示和权限合同。
+- `showOnLanding`：详情层级不在聚合页重复显示。
+
+共享解析函数：
+
+- `resolveManagementRoute(pathname, permissions)`：只返回当前有权识别的最具体匹配项。
+- `resolveManagementBreadcrumbs(pathname, permissions)`：在当前权限范围内沿 `parentKey` 生成可点击路径。
+- `isManagementPath(pathname, permissions)`：供侧栏选中判断，避免无权路径激活管理导航。
+- `getVisibleManagementItems(permissions)`：供管理首页渲染。
+
+管理根入口的 `anyOf` 从所有可见管理子项权限求并集派生，避免 `NavLinks.tsx` 再维护一份权限列表。页面可见性仍以现有 Router 权限守卫和服务端权限校验为硬边界；注册表权限负责导航信息最小披露，不能替代访问控制。
+
+`features/navigation/schema.ts` 先调用管理解析器，再回退到现有业务页面元数据；`NavLinks.tsx` 删除 `MANAGEMENT_ACTIVE_PATHS`；`SystemSettingsPage.tsx` 删除本地 `ITEMS`。
+
+## 3. Topbar 面包屑
+
+Topbar 已是所有 PC 页面稳定存在的壳层，比逐页增加返回按钮更可靠。管理路径命中时，把当前“标题 + 管理分组胶囊”表达为紧凑面包屑：
+
+```text
+管理 / 企业银行账户
+管理 / 人员 / 员工档案
+```
+
+- 非当前节点使用 `Link`；当前节点使用文本并带 `aria-current="page"`。
+- 管理首页仍显示普通标题「管理」。
+- 非管理业务页面保持现有 Topbar，不在本任务推广全系统面包屑。
+- 页面内部 `PageHeader` / `WorkspaceHeader` 不重复增加返回按钮，避免一页两套层级。
+- Topbar 从 `useAuth()` 取得当前权限后解析管理元数据；无权命中时不渲染受限标题或父链，避免权限守卫跳转前的短暂信息泄露。
+
+## 4. 路由覆盖门禁
+
+管理首页注册表是可见入口事实源，React Router 仍显式声明页面。测试用显式允许的管理路由清单核对：
+
+1. 每个 landing item 都能被 resolver 精确识别。
+2. 每个已注册详情路径返回正确父链。
+3. 所有管理页面标题均为自然中文。
+4. `SystemSettingsPage` 和 `NavLinks` 不再出现第二份管理路径数组。
+5. `/system/payment-accounts` 明确回归侧栏 active。
+6. 同一路径在权限具备/缺失时分别验证可见元数据与不披露行为。
+
+不在运行时解析 Router JSX，也不引入通用动态路由框架。
+
+## 5. 最近访问权限收口
+
+当前 `AppShellLayout` 会把路径和 `resolvePageMeta()` 标题写入 localStorage，但仓库中尚无读取最近访问的 UI。共享注册表接入后：
+
+- 写入管理路径前按当前权限解析；无权路径不写入受限标题。
+- 提供按当前权限过滤的读取函数，未来消费者只能读取过滤后的结果，不能直接展示 localStorage 原值。
+- 权限被撤销后，过滤结果立即隐藏受限标题和链接；可同步清理失效记录，避免旧数据长期残留。
+- 不把最近访问改成服务端存储，也不在本任务新增入口或页面。
+
+## 6. 单公司 UI
+
+后端模型保持不变。前端把 `LegalEntity` 解释为当前公司资料：
+
+- 0 条 active：显示「完善公司信息」初始化区。
+- 1 条 active：显示公司摘要和现有维护能力，隐藏多公司选择语义。
+- 多条 active：显示异常提示，不猜测默认公司，不自动清理。
+
+企业银行账户页面复用同一查询：
+
+- 0 条：只显示空状态和去公司信息的链接。
+- 1 条：内部自动使用其 ID，页面只读展示名称。
+- 多条：禁用保存并提示异常。
+
+暂不改变服务端 `legalEntityId` 请求字段，以保持 API、审计、付款快照和历史数据兼容。
+
+## 7. 文档口径
+
+`docs/产品口径.md` 当前编号到 R-5，因此新增 R-6，而不是留下缺号直接写 R-7。内容固化：单公司、内部 OA、非 SaaS、无公司切换；保留内部关系模型不等于对用户暴露多公司能力。
+
+## 8. 兼容与回滚
+
+- 无数据库迁移，无生产数据写入。
+- 回滚只需恢复前端注册表消费者和旧文案；API/数据不受影响。
+- 异常多公司场景保持 fail-closed，不会因前端自动选择错误公司影响付款账户。
+- 生产公司信息、付款账户和员工银行机构已通过既有路径完成配置；本任务只修复后续管理体验，不回读、不迁移也不改写这些真实资料。
+
+## 9. 视觉与技能边界
+
+项目要求页面视觉与交互以 `frontend-design` skill 裁决，但当前会话未提供该 skill。实施前若仍不可用，沿用现有 Topbar、Link、空状态、表单和管理卡片组件，不新增视觉体系；任何明显视觉重排需再次说明该限制。

+- [x] 运行 `trellis-before-dev`，读取 frontend、hyb-oa、项目治理和产品体验相关规约。
+- [x] 实施前再次检查 `frontend-design` skill 是否可用；不可用时只复用现有视觉组件，不自行发明新样式。
+- [x] 保护当前生产公司/银行资料；不连接生产、不写真实数据、不执行部署。
+
+## 2. 共享管理路由
+
+- [x] 建立管理路由注册表和最具体路径解析、父链、权限过滤函数。
+- [x] 迁移 `SystemSettingsPage` 的入口列表到共享注册表。

+- [x] 让 `resolvePageMeta` 从共享注册表解析管理标题，补齐当前遗漏页面和人员档案详情。
+- [x] 让管理根入口权限从注册表派生，并让 resolver、面包屑和侧栏 active 接收当前权限；无权路径不披露受限元数据。
+- [x] 收口最近访问写入/读取：写入前校验当前权限，读取时按当前权限过滤并覆盖权限撤销场景。
+- [x] 增加注册表完整性、重复 key/path、父级循环、自然中文标题和权限字段测试。
+
+## 3. Topbar 管理面包屑

+# 管理导航闭环与单公司体验收敛
+
+## Goal
+
+让管理人员从「管理」进入任一配置页后始终知道当前位置并能一键返回管理首页，同时把管理入口、侧栏归属和页面标题收敛到同一份路由事实源；在此基础上按“单公司、内部 OA、非产品化”边界简化公司信息和企业银行账户配置，不让用户面对无业务价值的多公司选择。
+
+## Background
+
+- 侧栏管理分组只有一个顶层入口：`client/src/features/navigation/schema.ts` 的 `ADMIN_NAV_ORDER` 仅包含 `/system/settings`。这符合“管理聚合入口”的产品方向，本任务不把每个配置页重新铺回侧栏。
+- 子页归属目前是重复且不完整的手工事实：`SystemSettingsPage.tsx` 维护管理首页入口；`NavLinks.tsx` 维护独立的 `MANAGEMENT_ACTIVE_PATHS`；`features/navigation/schema.ts` 的 `PAGE_TITLES` 又维护 Topbar 标题。三者已经漂移。
+- `/system/payment-accounts` 未加入 `MANAGEMENT_ACTIVE_PATHS`，因此当前页面不保持侧栏「管理」高亮。`PAGE_TITLES` 还缺少用户、部门、费用标准、报销模板、主数据、企业银行账户和通知渠道等多个管理页，缺失时可能回退为原始路径。
+- 管理子页没有统一父级面包屑。用户从聚合页进入配置页后，只能自行重新寻找侧栏「管理」，深链或刷新后更缺少上下文。
+- 本任务规划期间，生产曾因没有 `LegalEntity` 数据而使企业银行账户页面出现无选项的法人主体下拉框；管理员现已通过既有路径完成公司信息、付款账户和员工银行机构配置。该业务阻塞已经解除，但零公司状态仍需修复，避免以后初始化或测试环境再次走入死路。
+- 本系统只服务当前公司内部、小于 10 人团队，不作为产品发布，不支持多公司、多租户或公司切换。`LegalEntity` 仍作为付款账户、成本中心等数据的内部关联锚点保留，不因前端简化而重做数据库模型。
+- `docs/产品口径.md` 的权限口径目前编号到 R-5；单公司长期边界应作为下一条 R-6 固化，避免制造缺号的 R-7。
+
+## Priority
+
+1. 高：管理导航闭环与共享路由事实源，覆盖每次管理页面访问。
+2. 中：企业银行账户空状态与唯一公司自动关联，避免配置死路。
+3. 低：公司信息单例化表达和「法体」自然中文改名；不阻塞当前一次性生产录入。
+
+## Scope
+
+- 前端管理路由元数据、管理聚合页入口、PC 侧栏选中状态、Topbar 标题/面包屑和最近访问标题。
+- 主数据中的公司信息单例表达，以及企业银行账户页面在零个、一个或异常多个启用公司时的交互。
+- 与上述行为直接相关的前端类型、单元/组件测试和现有产品口径文档。
+- 不修改后端数据模型、权限、银行资料加密/审计、制单逻辑或生产数据；不包含付款详情结构统一。
+
+## Requirements
+
+### R1 管理路由单一事实源
+
+- 新建一份前端管理路由注册表，至少包含稳定 key、路径匹配规则、标题、父级、管理首页分组、图标、说明和权限要求。
+- 「管理」聚合页入口、侧栏「管理」选中判断、Topbar 页面标题/分组和管理面包屑必须从该注册表派生，不再分别维护 `ITEMS`、`MANAGEMENT_ACTIVE_PATHS` 和不完整的管理 `PAGE_TITLES`。
+- 注册表中的权限条件是路由元数据合同的一部分；管理根入口的权限集合从可见子项派生，不再在 `NavLinks.tsx` 单独维护另一份 `anyOf`。
+- React Router 的页面组件与权限边界继续在 `router/index.tsx` 显式声明；本任务不为追求配置化而把懒加载组件塞进产品元数据。
+- 注册表必须覆盖当前管理首页全部入口及必要详情层级，包括人员档案；新增管理页如果未登记，测试必须失败，而不是回退为原始路径后静默上线。
+
+### R2 管理导航闭环
+
+- PC 管理首页仍只占一个侧栏入口，不把低频配置页铺回主导航。
+- 任一管理子页的 Topbar 显示可点击父级路径，例如 `管理 / 企业银行账户`；点击「管理」固定回到 `/system/settings`，不依赖浏览器历史。
+- 人员档案等二级页面显示 `管理 / 人员 / 员工档案`；中间「人员」可返回人员列表。
+- 直接访问深链、刷新页面或从全局搜索进入时，面包屑和侧栏高亮仍正确。
+- 管理标题和父链解析必须接收当前用户权限；无权访问某个管理页时不得通过 Topbar 面包屑、父链或管理入口泄露该页面名称。
+- 管理首页本身只显示当前页标题，不显示自指的「返回管理」。
+
+### R3 页面标题与侧栏状态
+
+- `/system/payment-accounts` 及所有已登记管理子页均保持侧栏「管理」选中。
+- Topbar 不得把管理子页显示为原始 URL；管理页标题和分组必须与聚合页卡片一致。
+- 最近访问记录只写入当前有权访问的管理路由，并继续使用自然中文标题，不因注册表重构写入原始路径。
+- 读取最近访问时必须按当前权限重新过滤；用户权限被收回后，旧记录不得继续显示受限管理页面标题或链接。当前实现只有 localStorage 写入、尚无读取 UI，本任务修正写入/读取合同但不新建最近访问页面。
+
+### R4 单公司长期边界
+
+- 在 `docs/产品口径.md` 增加下一条可用编号 R-6：系统只服务当前公司内部，不做多公司、多租户、公司切换或面向外部客户的产品化配置。
+- 不新增 tenant/company switcher、跨公司权限、公司维度工作区或多公司初始化流程。
+- 保留 `LegalEntity` 表和现有关联作为内部账务/主数据锚点；本任务不重命名数据库表、不迁移外键、不删除历史能力。
+- 前端用户文案把「法体」统一改为「公司信息」或「公司」，不向普通管理员暴露会计/产品化术语。
+
+### R5 公司信息单例表达
+
+- 公司信息为空时，主数据页显示一次性初始化表单和明确说明。
+- 正常存在一条启用公司信息时，以单公司查看/维护方式展示，不提供公司切换器或鼓励继续创建第二家公司。
+- 若历史或测试环境异常存在多条启用记录，不静默选择，不自动合并或删除；显示管理员可理解的异常提示，并保留现有数据供单独治理。
+- 当前生产通过既有「主数据 → 法体」录入不被本任务阻塞；本任务不执行任何生产公司资料写入。
+
+### R6 企业银行账户配置不走死路
+
+- 没有公司信息时，不显示无解释的空法人主体下拉框；显示「请先完善公司信息」和可点击入口。
+- 恰有一条启用公司信息时自动关联并只读显示公司名称，不要求用户重复选择。
+- 异常存在多条启用公司信息时禁止猜测默认值，明确提示先处理公司信息。
+- 公司银行账户、员工银行资料、权限、加密、审计和通知合同保持不变；本任务不读取、回填或迁移真实完整账号。
+
+### R7 范围与设备
+
+- 本任务服务 PC 管理配置体验；按照现有产品规则，不新建复杂移动端管理台。
+- 窄屏通过现有 Topbar 菜单和可换行面包屑保持可用，但不新增移动专属公司/银行配置页面。
+- 付款详情结构统一、处理进度时间线、粘性操作区和银行制单业务逻辑不纳入本任务。
+
+## Acceptance Criteria
+
+- [x] 管理首页全部可见入口、侧栏归属、Topbar 标题和面包屑来自同一管理路由注册表；不存在第二份手工管理路径列表。
+- [x] 自动化逐项证明当前管理入口均有标题、权限、父级和路径匹配；新增未登记管理页会导致测试失败。
+- [x] 无权限用户看不到对应管理入口；深链访问期间 Topbar 不渲染受限页面名称或面包屑。
+- [x] 所有管理页面均显示 `管理 / 当前页面`，且「管理」可返回聚合页；员工档案显示 `管理 / 人员 / 员工档案`。
+- [x] 直接深链、刷新和前进后退后父链仍正确；管理首页不显示自指面包屑。
+- [x] 所有管理子页保持侧栏「管理」高亮，`/system/payment-accounts` 回归测试覆盖此前遗漏。
+- [x] Topbar 与最近访问记录不再为管理子页回退显示原始路径。
+- [x] 最近访问按当前权限过滤：撤销权限后，既有 localStorage 记录不再向用户显示受限页面标题或链接；聚焦测试覆盖权限变更场景。
+- [x] 主数据 UI 使用「公司信息」而不是「法体」，正常单公司状态不出现公司切换器或新增第二公司的主导入口。
+- [x] 零公司信息时，企业银行账户页提供明确说明和「完善公司信息」入口；一条时自动关联；多条异常时不静默选择。
+- [x] `LegalEntity` 数据模型、现有外键、付款账户加密/审计/通知和生产数据保持不变，无数据库迁移、无真实资料写入。
+- [x] `docs/产品口径.md` 以连续编号 R-6 固化单公司内部 OA 边界。
+- [x] 前端相关单元/组件测试、TypeScript 检查和生产构建通过；Trellis、敏感内容和 diff 门禁通过。
+- [x] 只有部署与公网检查通过后才通知用户线上验收；生产公司资料录入另由管理员执行。
+
+## Test Plan
+
+- 注册表契约测试：逐项校验稳定 key、唯一匹配、父级、标题、权限和管理首页可见项；覆盖未登记管理入口的失败用例。
+- 导航组件测试：覆盖管理首页、企业银行账户、人员列表与员工档案深链，验证侧栏高亮、Topbar 标题、面包屑链接和最近访问中文标题；同一路径分别验证有权和无权状态。
+- 权限变更测试：先以有权状态写入最近访问，再撤销权限读取，断言受限页面标题和链接均不返回；无权深链不渲染受限面包屑。
+- 公司状态组件测试：分别覆盖零个、一个和多个启用公司；验证引导入口、自动关联、只读公司名称和异常 fail-closed 行为。
+- 回归检查：确认管理页权限边界及 React Router 显式路由未改变，付款账户敏感字段不会进入测试快照或日志。
+- 前端门禁：运行相关 Vitest、`npm run typecheck` 与 `npm run build`。
+- 治理门禁：运行 Trellis task validate、Trellis governance、敏感内容检查（如当前流程要求）与 `git diff --check`。
+- 面向线上用户的验收仅在另行批准部署且公网检查通过后进行；生产配置和真实数据写入不属于自动化测试。
+
+## Out of Scope
+
+- 多租户、多公司切换、跨公司数据隔离、集团组织、合并报表或 SaaS 产品化。
+- 重命名或删除 `LegalEntity` 数据模型、外键迁移、历史数据合并和生产数据修复。
+- 把所有管理子页重新放进侧栏，或建设复杂的二级侧栏导航。
+- 移动端管理配置台、付款详情结构统一、审批/处理进度重构和银行制单业务变更。
+- 代替管理员录入公司全称、税号、银行账户或员工收款资料。
+- 取消或重建既有付款批次、生成制单、网银导入、上传回单或登记付款完成；这些属于独立的生产操作与制单验收。
