I think I see the problem. The test run on 2025-01-29 03:55:04 UTC [1] against numpy/1:2.2.2+ds-2 should have failed, and prevented numpy from migrating to testing, but debian/tests/control has all tests marked 'skip-not-installable' (please don't do that), so the test result was considered 'neutral' and numpy was eventually allowed to migrate.
