Eight directories the misc shard named moved to tests/unit on 2026-09-20, and one
missing path makes pytest-xdist collect [0 items] for the whole shard, which the
exit-5 tolerance turned into a green required check running nothing. The shared
Run tests step now drops a path that does not exist with a :⚠️: and runs
pytest over the rest, keeping option tokens verbatim.
