为什么:单文件 1100~1900 行的巨石模块让「改一处要通读全文」;同时注释里残留 大量已删台账的编号,以及「Flask/FastAPI 双栈迁移期」这类已失实的架构描述, 会误导后来者按不复存在的架构去改代码。 拆分(对外导入路径不变,行为零变更): - music_downloader.py -> music_downloader/(models/downloader/cover/_http/_log/_concurrency) - auth_system.py -> auth_system/(db/security/users/credits/ledger/mail/cards/backup...) - music_api.py -> music_api/(api/client/crypto/qr/cookies/compat/constants/errors) - services/runtime.py -> services/(api_service/_shared/_taskcore/downloads/batch/podcast/ streaming/tasks);services/runtime.py 保留为兼容门面 兼容性做法:各包用 __init__.py 以 __all__ 原样再导出全部符号,既有调用点 (auth_system.xxx / services.xxx / from music_api import Y)零改动;路径常量改为经包属性 动态读取(auth_system.DB_PATH),否则测试的 monkeypatch 会静默失效并写到生产库。 修复 9 处代码损伤(上一轮注释清理把 `()` 当「空括号残留」删掉所致;用「与拆分前逐字 等价」校验逐一定位,静态检查只会报出其中 4 处): - core/config.py ).strip() or '*' - core/state.py threading.Lock() x2 - qr_login.py datetime.now() / .strip() - music_downloader/downloader.py .lower() - services/podcast.py set() / time.time() x2 清理与删除: - 删除 部署文档.md / 功能介绍.md / README_私有包警告.txt - 清理指向已删台账与文档的过时编号注释;把「迁移期 / 两栈 / 双框架 / 已迁移」等 失实描述改写为现状描述(保留 `<-> Flask /path` 映射表等仍有价值的契约来源说明) - _mkpkg.py:公开包剔除清单去掉已不存在的文档名;私有包警告改为自包含 - pyproject.toml:补 pythonpath = ["."],使裸跑 pytest 不再 import core 失败 验证:ruff 全通过;pyright 0 errors / 0 warnings(102 文件);pytest 144 passed; 真实 uvicorn 冒烟 6 条路由符合预期且生产 data/ 指纹未变;忽略注释的逐字等价性校验通过。
