`python3 -m unittest tests/test_dashboard_contract.py` resolves the path to a module name and tests/ is not a package, so it imported on the author's 3.14 and not on the gate host's 3.10. The file resolves its own paths and has a main guard, so run it directly. differential-oracle was also the last suite not routed through {{upstream}}; it passed only because the caller happened to export STREAM_UPSTREAM_REPO.
