为什么：用 AST 级引用分析（而非文本 grep——同名符号会互相掩盖）确认这些 符号全项目零引用。文本 grep 查不出的原因是它们都有「活着的同名兄弟」： services/downloads.py（共 6 个，93 行） _parse_cookie_str / _global_music_u / _vip_name / _detect_vip / _admin_client / _user_client —— 活的是 core.media.parse_cookie_str、web/routers/music.py、account.py 的版本 随之失效的 import：USER_COOKIE_FILE / GLOBAL_MUSIC_U_CACHE / VIP_PROBE_LOCK / account_info / detect_vip_by_probe / QRLoginClient services/api_service.py APIResponse 类（29 行）—— web/response.py 才是活的响应封装 services/_shared.py _rate_ok —— 逐字复制 web.ratelimit.rate_ok core/utils.py safe_int / safe_console_print —— 活的是 web/request_utils.safe_int core/repo.py all_settings / get_user_by_name —— auth_system.get_user_by_name 才是活的 core/db.py / web/auth_state.py / web/request_utils.py execute_many / _safe_register_credits + secrets_rand / dedup_ids 结果：生产代码死代码候选 13 → 0（余下 118 个全是 pytest 测试函数，属正常）。

"""站点数据异步读写仓储。
|
|
|
|
直接读写 auth_system 建立的同一份 SQLite（同一 DB_PATH / 同一 schema），
|
|
但走 core.db 的 aiosqlite 异步层——读并发、写串行、WAL 读写同时进行。
|
|
|
|
设计约束：本模块**不改动** auth_system 既有 schema，只做读写；字段口径与
|
|
auth_system 保持一致（键名、默认值），读写同一份库文件。
