- cli_handler_base.py 拆分为 7 个 mixin (event/monitor/prefetch/request/sse_helpers/stream/sync) - usage/service.py 拆分为 6 个子模块 (types/active_requests/cache_analysis/lifecycle/pricing/query/recording) - models/database 拆分为独立模型文件 (auth/misc/model/provider/stats/usage/user) - DUMMY_THOUGHT_SIGNATURE 常量提升到 core/api_format/conversion/constants 统一管理 - task/service.py 内联导入提升为顶层导入 - 流处理函数签名移除冗余的 http_client 参数
