- TushareProvider：频率超限按指数退避重试（不再一次 200/min 即中断），最长等待 30s
- SinaProvider 重构（参考 cc-cursor 公开接口实现）：
· 新增财务通道 CompanyFinanceService.getFinanceReport2022(source=gjzb) → FinancialIndicator
（report_date / announce_date=publish_date），与 Tushare fina_indicator schema 一致
· 日 K 保留 jsonp（前复权），统一 UA + 重试
· 不支持方法仍抛 DataSourceNotSupported（复权因子/交易日历/基础信息）
- FailoverProvider 现在可对 daily 与 financial 兜底（CLI _failover_provider 接 SinaProvider）
- DailyBar + stock_daily 表新增 source/adjust 列：新浪兜底行标记 sina/qfq，
Tushare 恢复后 --resume 按同键覆盖回不复权 → 两源格式一致且可追溯
- 迁移 91c4e27a03fb 已生成；执行需在全市场同步结束后：uv run alembic upgrade head
- 测试 34+ 项（新浪财务解析/格式一致/限速退避等）通过

"""新浪财经 Provider —— 备用数据源。
|
||
|
||
通道（公开接口方案参考 cc-cursor/finance/data/sources/sina_source.py）：
|
||
1. 财务：quotes.sina.cn CompanyFinanceService.getFinanceReport2022（source=gjzb，
|
||
匿名免费、一次多期），含披露日 publish_date → FinancialIndicator
|
||
（symbol / report_date=end_date / announce_date=publish_date），schema 与
|
||
Tushare fina_indicator 一致 —— 用于财务兜底（保留防未来函数所需的公告日）。
|
||
2. 日 K：quotes.sina.cn getKLineData（jsonp，**前复权**）。新浪无「不复权 + 独立复权
|
||
因子」，因此日线兜底行标记 source=sina、adjust=qfq，与主口径区分；Tushare 恢复
|
||
后 --resume 会按日覆盖回不复权行。
|
||
|
||
能力边界（其余接口新浪不支持 → DataSourceNotSupported）：
|
||
get_stock_basic / get_trade_cal / get_adjust_factor。
