- 流式转换补齐 chat→responses / responses→chat / messages→responses 的工具调用（此前只转文本，SDK 客户端拿不到 tool_calls）；completed 事件携带完整 output 数组 - Anthropic 协议上游同时发 x-api-key（官方 API 不接受 API key 走 Bearer）并透传 anthropic-beta - 请求侧校验模型存在且启用：禁用模型 404 model_not_found，不再只是从 /v1/models 消失、实际照发照扣费；空模型名 400 - 模型在请求中途被删时按 0 记账留痕，不再按硬编码示例价扣用户的钱 - finishUsage 新增一行式请求日志（trace/user/model/channel/tokens/cost/status/latency），记账是异步的，日志是唯一即时排障依据
