-"""image_analysis v8 + storyboard v3 叙述优先重写版（架构大简化）
-
-Revision ID: 105_narration_first
-Revises: 104_v8_display_markdown
-Create Date: 2026-10-07
-
-变更：
-1. image_analysis v8：用「叙述优先」版整体替换 104 的 append 版——VLM 主交付物是
-   自然叙述 summary_markdown，结构化字段仅保留 type/name/brand/has_person，
-   顶层 products 改名 images；v8 active，其余 image_analysis 全部 deactivate。
-2. storyboard v3：整体替换为风格重写版（口播口语化、画面有画面感、
-   copy_display_markdown 流畅叙述）；v3 active，其余 storyboard deactivate。
-3. intent_parsing 类型模板全部 deactivate（意图解析步骤已删除）。
-模板内容直接取自 packages.application.viral_video.prompts.DEFAULT_TEMPLATES，
-保证代码默认值与 DB seed 完全一致。

-"""V2 快速路径：vision client（默认 image_analysis 能力）强约束 JSON-only 调用。
+"""doubao-seed-2.1-lite 强约束 JSON-only 调用。

-要点：
- 通过 ai_router.get_vision_client() 获取 client；
- enable_thinking=False 关闭推理链，response_format=json_object 强约束 JSON；
- system/user prompt 优先读后台模板（v8 叙述优先），DB 不可用时用 prompts.py 默认；
- temperature=0.1（稳定输出 JSON）；两次尝试（第二次去 json_object 约束）。
+目标：替代"人体属性/商品检测/图像标签"三个火山不存在的专用云端 API。
+设计要点：
+- system prompt 极致精简，只给字段 schema 和强约束（禁止自然语言、禁止 markdown）
+- max_tokens=350（比旧 VLM 的 1200 小很多，降低延迟）
+- temperature=0.1（极低，稳定输出 JSON）
+- timeout=8s（够快，失败则由外层走 pro VLM 兜底）
+- 期望返回纯 JSON object（无 ```json 包裹、无解释文字）

-封装 Ditto FastAPI（部署在 5060Ti GPU 节点，Tailscale 内网可达）：
- GET  /health               健康检查
- POST /generate             生成口型视频（同步返回 MP4 流）
-
-关键特性：
- 入参：video_url（人物模板视频 URL） + audio_url（TTS 音频 URL） + script（文案原文）
- 出参：直接返回 video/mp4 字节流（自带音频，无需二次混流）
- 429 时指数退避重试（最多 ditto_max_retries 次）
- 500/超时视为失败
- 输出 MP4 字节流转存到自家 OSS，返回公网 URL
-
-注意：
- 保留 MuseTalk/GPU 路径不变；本服务作为更高优先级的第三条口型路径
- 不传 emotion/表情精细控制，使用默认 emo_global=4（中性）+ use_script_emo=true（关键词驱动表情）
- Ditto 输出自带音视频，不需要 GFPGAN 超分，不需要 ffmpeg 音视频混流
