> Linux was intelligent enough to keep the i-node references even if the parent directory was different so the docker container kept working inside the deleteme_after_202202 directory.

Who would have been launching a container inside the deleteme directory? They were very lucky if that's how they found it. How long did it take to discover that?

The container wasn't launched inside deleteme_after_202202 it just kept working after somebody did the equivalent of:

mv /opt/redash /opt/deleteme_after_202202

until the machine was rebooted.
