+## 2026-03-15 — v0.8.0: Seedance API 全流程修复 + TOS 视频持久化
+
+**状态**: ✅ 已完成 | **验收**: ✅ 通过（本地端到端测试）
+
+### 变更内容
+1. **音频引用支持** — 后端 content_items 构建新增 `audio` 类型分支，Seedance API 可接收音频参考素材
+2. **视频 TOS 持久化** — Seedance 返回的临时 URL（24h 有效）自动下载并上传到 TOS，生成永久 CDN 链接；失败时降级使用临时 URL
+3. **移除硬编码密钥** — ARK_API_KEY 默认值从测试 key 改为空字符串，避免生产环境误用
+4. **渐进式轮询** — 前端轮询从固定 3 分钟改为渐进式：前 2 分钟每 10s → 2-5 分钟每 30s → 5 分钟后每 60s
+5. **TOS 新桶配置** — 切换到独立桶 `airdrama-media`（cn-beijing），TOS 配置默认值更新
+6. **K8s Secret 注入** — TOS_ACCESS_KEY / TOS_SECRET_KEY 通过 K8s Secret 注入，CI/CD 自动创建
+7. **CI/CD 密钥同步** — deploy.yaml 新增 TOS 密钥到 kubectl secret 创建命令
+
+### 变更文件
+| 文件 | 改动 |
+|------|------|
+| `backend/apps/generation/views.py` | 新增 audio content_item 分支 + 完成时 TOS 持久化逻辑 |
+| `backend/utils/tos_client.py` | 新增 `upload_from_url()` — 从 URL 下载并上传到 TOS |
+| `backend/config/settings.py` | TOS 桶/区域/端点改为 airdrama-media (cn-beijing)；ARK_API_KEY 默认值清空 |
+| `web/src/store/generation.ts` | setInterval → setTimeout 渐进式轮询 |
+| `k8s/backend-deployment.yaml` | 新增 6 个 TOS 环境变量（AK/SK from Secret） |
+| `.gitea/workflows/deploy.yaml` | kubectl secret 新增 TOS_ACCESS_KEY / TOS_SECRET_KEY |
+
+### 触发原因
+- Seedance API 文档审查发现：音频引用未传递、视频 URL 24h 过期、密钥硬编码
+- 需要独立 TOS 桶存放生成视频（原桶为同事的阿里云 OSS）
+
+### 备注
+- 本地测试通过：文生视频 "一只猫在阳光下伸懒腰" → 87,300 tokens → 永久 TOS URL
+- Seedance 2.0 定价：不含视频输入 46 元/百万 tokens，含视频输入 28 元/百万 tokens
+- 资源包 5,000,000 tokens，约可生成 57 个 4 秒 720p 视频
