+## 题库导出对接
+
+租户后台题库导出统一走后端生成结构化 payload，前端不要直接查 Supabase 表拼导出文件。当前后端已支持 JSON、`paper_json` 和 `print_payload` 三类基础导出，适合先做后台“导出 JSON/试卷预览”功能；PDF/Word 二进制、水印和发布到资料下载后续由 worker 增强。
+
+可用接口：
+
+```text
+POST /api/tenant-content/exports/questions
+GET  /api/tenant-content/exports/jobs
+```
+
+导出范围：
+
+| scopeType | scopeId | 用途 |
+| --- | --- | --- |
+| `collection` | `question_collections.id` | 导出某个题目列表或试卷集合 |
+| `entry` | `content_entries.id` | 导出某个题库入口下全部已发布题目 |
+| `content_node` | `content_nodes.id` | 导出某个分类节点及其子节点下全部已发布题目 |
+
+普通题库 JSON 导出：
+
+```json
+{
+  "scopeType": "collection",
+  "scopeId": "<questionCollectionId>",
+  "format": "json",
+  "exportType": "questions",
+  "includeAnswers": false,
+  "includeExplanations": false,
+  "options": {
+    "title": "天津专升本题库导出"
+  }
+}
+```
+
+试卷 payload 导出：
+
+```json
+{
+  "scopeType": "content_node",
+  "scopeId": "<contentNodeId>",
+  "format": "paper_json",
+  "exportType": "paper",
+  "includeAnswers": true,
+  "includeExplanations": true,
+  "options": {
+    "title": "全真模拟试卷",
+    "durationMinutes": 120,
+    "watermarkText": "仅供内部使用"
+  }
+}
+```
+
+响应关键结构：
+
+```json
+{
+  "job": {
+    "id": "...",
+    "status": "completed",
+    "questionCount": 1,
+    "outputHash": "..."
+  },
+  "export": {
+    "_tikuExport": "3.0",
+    "jobId": "...",
+    "summary": {
+      "questionCount": 1,
+      "sectionCount": 1
+    },
+    "sections": [],
+    "questions": [],
+    "files": [
+      {
+        "filename": "天津专升本题库导出.json",
+        "mimeType": "application/json",
+        "encoding": "base64",
+        "contentBase64": "..."
+      }
+    ],
+    "renderHints": {
+      "pdfLayout": "paper",
+      "pageSize": "A4",
+      "answerPlacement": "inline_or_appendix"
+    }
+  }
+}
+```
+
+前端处理规则：
+
+- 导出按钮只给具备租户内容编辑权限的后台成员展示；接口仍以后端 `TENANT_CONTENT_EDITOR_REQUIRED` 为准。
+- 下载 JSON 时使用 `files[0].contentBase64` 生成 Blob，文件名使用后端返回的 `filename`。
+- `includeAnswers=false` 时，顶层答案字段和阅读理解/案例分析的子题答案都会被后端脱敏；前端不要在本地重新合并答案。
+- `includeExplanations=false` 时，不展示解析，也不要从题目详情接口额外补解析。
+- `paper_json` 可先用于后台试卷预览和打印；正式 PDF/Word 导出等后端 worker 完成后再接二进制文件下载。
+- `GET /api/tenant-content/exports/jobs?scopeType=collection&scopeId=...` 用于后台导出历史；当前记录 metadata 和输出 hash，不长期保存完整导出内容。
+- 跨租户导出会返回 404 或 403，前端不要重试其它租户 ID。
