+## Scenario: Shared RMB Display
+
+### 1. Scope / Trigger
+
+- Trigger: a reimbursement, invoice, fee-control or payment UI displays a CNY amount received as a string, number or nullable field.
+
+### 2. Signatures
+
+- Shared formatter: `formatMoney(value: string | number | null | undefined): string` in `client/src/lib/displayFormat.ts`.
+
+### 3. Contracts
+
+- Reuse the shared formatter across PC and mobile consumers; do not add page-local `Intl.NumberFormat` helpers for the same amount.
+- Valid amounts display the CNY symbol, thousands separators and exactly two decimal places. Missing, empty or non-finite values display `-`; they must not become `¥0.00`.
+
+### 4. Validation & Error Matrix
+
+- `1860` / `"1860"` -> `¥1,860.00`.
+- `"550.5"` -> `¥550.50`.
+- `null`, `""`, invalid text or a non-finite number -> `-`.
+
+### 5. Good/Base/Bad Cases
+
+- Good: a PC detail total, mobile detail total and invoice summary all use `formatMoney`.
+- Base: a real zero amount displays `¥0.00`.
+- Bad: use string interpolation such as `` `¥${amount}` `` or coerce a missing amount with `Number(value ?? 0)`.
+
+### 6. Tests Required
+
+- Focused frontend regression covers integer, fractional and thousands-separated amounts on PC and mobile.
+- Run `cd client && npm run typecheck && npm run build`.
+
+### 7. Wrong vs Correct
+
+#### Wrong
+
+```tsx
+<span>¥{detail.totalAmount ?? "-"}</span>
+```
+
+#### Correct
+
+```tsx
+<span>{formatMoney(detail.totalAmount)}</span>

 - When `WorkflowTaskDetail.reimbursement` exists, the task detail exposes an explicitly named `查看完整报销单` or `查看报销单` link near the reimbursement summary.
 - Reuse the existing business detail route and its permissions. Do not duplicate reimbursement items, invoice or attachment viewers inside the approval page merely to add reachability.
 - Mobile navigation passes the current approval task URL through the existing `state.from` convention so the business detail back button returns to that task. This is a one-level source contract, not a new nested return stack.
+- PC reimbursement list and task-detail exits use the same one-level `state.from` contract. The detail page accepts only `/reimbursements` list URLs and `/workflow/tasks/:id`; absolute/protocol-relative URLs, hashes, other modules and the current page are rejected.

+
+- 报销列表把当前 `pathname + search` 作为 `location.state.from` 传给报销详情或审批任务；审批任务进入报销详情时把当前任务路径作为来源。PC 详情仅接受 `/reimbursements` 列表和 `/workflow/tasks/:id` 两类内部来源，拒绝绝对 URL、协议相对 URL、hash、当前页和其他模块路径。
+- 报销详情在 `EntityOverviewHero` 之前渲染一个文字明确的左侧返回控件；返回采用 replace，避免“返回后浏览器后退又回详情”的循环。无可信来源时降级 `/reimbursements`。
+- `displayFormat.ts` 新增可接受 `string | number | null | undefined` 的人民币格式化函数；PC/移动详情删除各自金额 formatter，统一复用。列表页本轮不做横向重构，避免扩大已批准范围。
+- 移动材料区继续承接发票添加；固定底栏删除同名次级按钮，只渲染提交主动作。固定栏的 safe-area、loading、禁用和提交校验保持不变。
+- 回退只需还原前端提交；不涉及 API、数据库、权限、workflow、生产配置或真实数据。
