+# Change: 资产详情前代后代换货标识
+
+## Why
+
+资产详情虽然可展示业务状态和世代编号，但运营无法判断当前资产在换货链中的位置，也无法在具备权限时快速前往关联资产。需要基于后端返回的换货链路数据明确展示前代和后代资产关系。
+
+## What Changes
+
+- 扩展资产解析响应，读取 `exchange_trace.previous_asset` 和 `exchange_trace.next_asset`。
+- 前代资产存在时，在当前资产详情展示“换货新资产”标签与前代资产信息。
+- 后代资产存在时，在当前资产详情展示“已换出旧资产”标签与后代资产信息。
+- 中间资产同时展示前代和后代换货标识。
+- 当关联项 `can_view=true` 时允许跳转资产详情；为 `false` 时仅展示标识文本，不提供跳转操作。
+- 不由前端根据换货状态、世代编号或其他字段自行推导换货链；关联项为空时不展示对应区域。
+
+## Impact
+
+- Affected specs: `asset-information`
+- Related active changes: `add-asset-status-generation-display`（共享资产世代和详情展示区域）
+- Affected code:
+  - `src/types/api/asset.ts`
+  - `src/views/asset-management/asset-information/types.ts`
+  - `src/views/asset-management/asset-information/composables/useAssetInfo.ts`
+  - `src/views/asset-management/asset-information/components/BasicInfoCard.vue`
+- API contract:
+  - `GET /api/admin/assets/resolve/{identifier}`

+## ADDED Requirements
+
+### Requirement: Asset Exchange Generation Trace Display
+
+The asset information page SHALL display exchange generation relationships exclusively from `exchange_trace.previous_asset` and `exchange_trace.next_asset` returned by `GET /api/admin/assets/resolve/{identifier}`. The frontend MUST NOT infer the exchange chain from asset status, generation, or exchange status.
+
+#### Scenario: Display previous asset for a replacement asset
+
+- **GIVEN** 用户正在查看资产信息页
+- **WHEN** 解析响应包含非空的 `exchange_trace.previous_asset`
+- **THEN** 页面 MUST 显示“换货新资产”标签
+- **AND** 页面 MUST 展示前代资产的标识符和换货单号
+
+#### Scenario: Display next asset for a replaced asset
+
+- **GIVEN** 用户正在查看资产信息页
+- **WHEN** 解析响应包含非空的 `exchange_trace.next_asset`
+- **THEN** 页面 MUST 显示“已换出旧资产”标签
+- **AND** 页面 MUST 展示后代资产的标识符和换货单号
+
+#### Scenario: Display both relationships for an intermediate asset
+
+- **GIVEN** 用户正在查看位于换货链中间的资产
+- **WHEN** 解析响应同时包含非空的 `previous_asset` 和 `next_asset`
+- **THEN** 页面 MUST 同时展示“换货新资产”和“已换出旧资产”两个关联区域
+
+#### Scenario: Hide absent exchange relationship
+
+- **GIVEN** 用户正在查看资产信息页
+- **WHEN** `previous_asset` 或 `next_asset` 为 `null`、空值或未返回
+- **THEN** 页面 MUST NOT 展示对应的换货关联区域
+- **AND** 前端 MUST NOT 根据资产状态、世代编号、换货单状态或其他字段推导该区域
+
+### Requirement: Exchange Related Asset Navigation Authorization
+
+The asset information page SHALL allow navigation to a related exchange asset only when that relationship item has `can_view=true`.
+
+#### Scenario: Navigate to authorized related asset
+
+- **GIVEN** 换货关联资产项的 `can_view=true`
+- **WHEN** 用户点击关联资产标识符
+- **THEN** 系统 MUST 跳转到该关联资产的资产详情
+- **AND** 跳转 MUST 使用关联项返回的 `identifier`
+
+#### Scenario: Render unauthorized related asset as text
+
+- **GIVEN** 换货关联资产项的 `can_view=false`
+- **WHEN** 页面渲染换货关联区域
+- **THEN** 页面 MUST 展示关联资产标识符和换货单号
+- **AND** 页面 MUST NOT 将关联资产标识符渲染为可点击跳转操作
+
+### Requirement: Exchange Trace Response Contract
+
+The frontend asset resolve contract SHALL support optional `exchange_trace.previous_asset` and `exchange_trace.next_asset` items, each with `asset_type`, `asset_id`, `identifier`, `exchange_no`, and `can_view`.
+
+#### Scenario: Read exchange trace response fields
+
+- **WHEN** 前端解析 `GET /api/admin/assets/resolve/{identifier}` 响应
+- **THEN** 前端类型 MUST 支持 `exchange_trace.previous_asset` 和 `exchange_trace.next_asset`
+- **AND** 每个非空关联项 MUST 支持读取 `asset_type`、`asset_id`、`identifier`、`exchange_no`、`can_view`

+## 1. API Contract
+
+- [x] 1.1 更新资产解析响应类型，支持 `exchange_trace.previous_asset` 和 `exchange_trace.next_asset`。
+- [x] 1.2 定义换货关联资产类型，读取 `asset_type`、`asset_id`、`identifier`、`exchange_no`、`can_view`。
+
+## 2. Asset Detail Exchange Trace UI
+
+- [x] 2.1 `previous_asset` 存在时展示“换货新资产”标签和前代资产信息。
+- [x] 2.2 `next_asset` 存在时展示“已换出旧资产”标签和后代资产信息。
+- [x] 2.3 当前资产同时存在前代和后代时，同时展示两个关联区域。
+- [x] 2.4 关联资产为空时隐藏对应区域，不通过换货状态或世代编号推导关联链路。
+
+## 3. Exchange Trace Navigation
+
+- [x] 3.1 `can_view=true` 时允许点击关联资产标识跳转资产详情。
+- [x] 3.2 `can_view=false` 时仅展示关联资产标识文本，不渲染跳转操作。
+
+## 4. Verification
+
+- [ ] 4.1 验证旧资产、新资产、中间资产和无关联资产的展示正确。
+- [ ] 4.2 验证有权限和无权限关联资产的跳转行为正确。
+- [x] 4.3 运行相关前端校验，并执行 `openspec validate update-asset-exchange-generation-links --strict`。
