restore main tree to deployed 3bafd30 (HEL-529 校准)

Revert the full revert 6f99ee9 so main's tree content is byte-identical
to 3bafd30, which is the commit currently deployed and healthy on the
8766 xiaobai-datahub container (image hel531-3bafd30). No history
rewrite, no force push; this is a normal forward commit on top of main.
