新通道:腾讯 MaaS u2 模型(云知声),OpenAI 兼容协议 - 端点:https://maas-api.hivoice.cn/v1 - 模型:u2(翻译专用,实测 + 锁定 prompt 后译文质量稳定) - 备用链路:TMT 配额耗尽 / TMT 失败时自动降级到 MaaS 关键 prompt 工程(锁定): - 必须用 user 提供的固定中文 prompt,否则 u2 会把译文放进 reasoning_content 而 content 返乱码 - 限定只接 EN/JA → ZH - 中文输入固定返回拒绝文案 新增/改动: - backend/app/services/translation/tencent_maas.py: 新建 - backend/app/services/translation/service.py: 备用链 maas → local,初始化失败友好降级 - backend/app/config.py: 加 tencent_maas_* 4 个配置 - .env.example: 文档化
