# NAS 端：每日同步 VPS valuation + financial_abstract（ak-eod 每日 --force 全量重写）。
#
# 设计迭代（2026-07-31 实测）：
# - ak-eod 每日 --force 重写 valuation/financial_abstract（估值随股价每日变）
# - bsdtar --newer 慢盘 stat 不可行；python tarfile 打包 9.5s/1.1GB OK
# - 但 scp 单 tar 1.1GB 跨公网 broken pipe（连接断全丢，retry 难救）
# - 改 scp -r 目录：多文件独立传，单文件失败不牵连（sync_parquet.sh 验证 6.24G 鲁棒）
#
# 调度：ak-eod 19:00 跑完（~21:30）后延迟跑。
