Note

Convert EXPECTED_SUBMISSION_READINESS_SURFACES entries to Path objects in tests

Updates test_metadata.py to store absolute Path objects (rooted at ROOT) in EXPECTED_SUBMISSION_READINESS_SURFACES instead of plain strings. The test loop is updated to call surface.read_text() directly rather than joining with ROOT first. File targets are unchanged.
