M0-M4: 推倒重来基线(基建+用户/密钥/核心代理+前端+管理后台+三协议互转)
- 后端 Go+Gin+GORM: 配置(OT_ env)/SQLite/Postgres 双驱动、用户体系(argon2id+JWT access/refresh)、 API Key(sk- 48位, 仅存 SHA-256 哈希) - 代理网关: /v1/chat/completions、/v1/responses、/v1/messages、/v1/models;错误按客户端协议返回 - 三协议互转(convert 包): Chat↔Messages↔Responses 请求/响应 + 流式 SSE 逐事件转换(直通优先) - 用量计费: 异步批量记账、余额扣减、balance_logs、usage_daily 日聚合 - 管理 API: 用户/渠道 CRUD+测试+模型导入/模型定价+绑定/统计/系统配置 - 前端 Vue3+TS+Tailwind(taste-skill 设计 tokens): Landing/登录注册/控制台/管理后台, 自建组件+Phosphor 图标+自建 SVG 趋势图, 已过 web-design-guidelines 复查 - mock 上游: OpenAI+Anthropic 双协议模拟(含流式) Co-Authored-By: Claude <noreply@anthropic.com>
