However, the most striking anomaly is in the topology section: this is a data intelligence platform designed to catalog and understand relationships in external systems, yet it has ZERO viable joins among its own 61 defined relationships. Before concluding this is the most counterintuitive finding, I should verify the relationship metadata to understand what these 61 'defined' relationships are and why none are viable.",
