It's difficult to tell exactly where here, but any view currently using variant cross compare shows what looks like reasonable results in the top level report, but when drilling down to a test details report, you get no regressions, and the same job being compared to itself.

Example top level report.

Example test details report showing the same jobs comparing against themselves, and no regression. This showed 85% pass rate down from 100% pass rate in the top level table at the time of filing.

This functionality will be critical for navigating RHEL 10 in OCP 5.0.

The resolution to this issue should include verifying that representative Test Details links are available from both the main view and cross compare views both from the top level views and after drilling down to get to the test details either through full drill down or partial drill down and then using the regressions dialog.
