- web/routers/stream.py：/api/v1/audio_stream 音频范围流代理 · 签名校验（core.security，密钥同源两栈互认）；HEAD 直接 200 不请求上游 · Range 原样透传上游（206 + Content-Range，拖动进度可用） · 编码透明：上游带 Content-Encoding 时不沿用压缩前长度（同 Flask F92） · StreamingResponse 16KB 分块，finally 关闭上游（下游中断亦释放） - core/http_client.py 增 open()：返回未关闭流式响应，便于先读状态码再转发 - web/routers/delivery.py：/download/result、/download/batch_zip/result · 归属 403 / 进行中 202 / 暂停 200 / 取消 200 / 失败 500 / 缺失 404 分支逐一对齐 · FileResponse 流式交付 + no-store + X-Download-Filename；清理由监控线程统一回收 验证：pytest 51/51（新增 5 项流代理：无效 token/HEAD/全量/Range 透传/上游关闭）； ruff All checks passed；pyright 0 errors；奇偶校验 26/26；实测 5.2MB 流与 Range 206 正确。
