feeeei	75faedda95	计费：fast/priority 按上游响应实际档位只降不升计费 ... 此前 OpenAI service_tier 与 Anthropic speed 的计费档位只看请求侧，上游 因容量把 priority/fast 静默降为 default/standard 时仍按 2x 收费。现在： - upstreamResponseModelObserver 同时观察响应侧档位：OpenAI 只信终止事件 与无类型 body 里的 service_tier（response.created 为请求回显，忽略）， Anthropic 读 usage.speed；查找仅在带 model 的帧上触发 - ResolveBillingServiceTier 只降不升：响应档位比请求便宜才采纳，更贵、 未知或缺失一律沿用请求侧，与图片尺寸归并、response_model 计费的 "不得更贵"不变式一致 - usage_logs.service_tier 记录实际计费档位，降级写 billing.service_tier_downgraded 审计日志；HTTP、WS 及 ws_v2 relay 全覆盖	2026-08-23 16:53:28 +08:00
