为什么：aria2p 内部是 requests + websocket-client 的同步实现，每个 RPC 都是一次 「同步网络 IO 藏在 to_thread 里」——线程池跑得再满也不产生真正的并发，每次轮询 还要额外付一次线程跳转。这是本项目最后一处此类残留，删掉后整个进程的网络 IO 都走同一个 aiohttp 连接池。 改动： - music_downloader/_aria2.py 整体重写：新增 _Aria2Rpc，直接向 aria2 的 JSON-RPC 2.0 端点发 getVersion / addUri / tellStatus / forceRemove / removeDownloadResult，一律走 core.http_client.request_once（不重试，与 aria2p 口径一致）；新增 Aria2RpcError 承载 HTTP 200 + error 对象的协议错误。 - _abort 逐条复刻 aria2p.remove(force=True, files=?, clean=True) 语义：终态走 removeDownloadResult；在途先 forceRemove 再清结果表；控制文件 .aria2 无条件 删除（clean=True 默认）；仅当 files 且主移除成功才删数据文件。 - get_backend / _try_start 改原生异步：asyncio.Lock 单飞 + await rpc.get_version() 探活，不再用 to_thread 包 subprocess.Popen；超时路径改 to_thread(_reap) 回收。 - 新增 Protocol _Rpc / _ProcessHandle（补 returncode 声明）——只声明本模块真正 调用的方法，测试据此用轻量替身驱动状态机，不必依赖真实 aria2 进程。 - pyproject.toml 删 aria2p 依赖并同步更新过时注释；uv lock 连带移除 8 个传递 依赖：requests / urllib3 / websocket-client / charset-normalizer / loguru / platformdirs / win32-setctime。至此全仓无任何 requests 栈。 - tests/test_aria2.py 重写为 21 项用例（_FakeRpc / _FakeProc / _LiveProc / _FakeHTTP 替身），新增终态体积守卫、_try_start 三分支（就绪重试 / 超时不就绪 杀进程 / 进程提前退出）与 JSON-RPC 信封四例。 - tests/test_downloader.py 的 get_backend 替身由同步 lambda 改为协程——调用点 已直接 await，同步替身会被 await 成 None 而报 TypeError。 验证（在 aria2p 已物理移除的环境上复核，故能真正证明无残留依赖）： - uv run ruff check . → All checks passed! - uv run pyright → 0 errors, 0 warnings, 0 informations - uv run pytest → 392 项，0 失败 / 0 error / 0 skipped（基线 382，净增 10） - data/site.db sha256 前后一致（a19f5dbf…6487），无 -wal/-shm 残留

"""MusicDownloader.download_music_file 的行为契约测试（沙箱，不触碰生产 data/）。
|
||
|
||
为什么：download_music_file 是**唯一**的音频落盘路径——单曲 worker 与音乐批量
|
||
ZIP 都经它，约 205 行 / 圈复杂度 47，此前**零直接测试覆盖**（test_zip_workers 里
|
||
只有一个 stub）。它同时承担缓存校验、断点续传、内容嗅探、体积上限、取消语义、
|
||
重试退避与元数据写入，任何一条被拆坏都不会有测试报警。
|
||
|
||
断言只依赖「调用后世界里发生了什么」——返回值、磁盘上的文件、发往网络的请求——
|
||
不引用任何内部函数名，因此本文件可作为后续拆分的等价性验证器。
|
||
|
||
替身约定（均为模块级符号，替换点在 downloader 模块命名空间）：
|
||
- 网络：``_http``（core.http_client 的进程级异步客户端）——替身提供
|
||
``async open(method, url, **kw)``，返回带 ``status``/``headers``/``content``
|
||
的未关闭响应；分块读取走**真实的** ``iter_chunks``，顺带钉住「读取期异常
|
||
收敛为 UpstreamNetworkError」这条边界。
|
||
- aria2：``get_backend``（**协程**替身，返回 None = 强制走内置 HTTP 通道）
|
||
- 内容嗅探：``_sniff_audio_header``（默认放行，按需置 False）
|
||
- 元数据写入：``MusicDownloader._write_metadata``（不真跑 mutagen）
