hub-mariadb on 1a0db684 (run 41293899868): 1 failed, 4674 passed, 30 skipped. The fix in #1029 worked: no more errors. The last failure:

tests/test_migrations.py::test_the_single_schedule_becomes_one_series_with_its_rounds_and_grants: ProgrammingError 1064 near '), (), (), 0, (), '2026-11-01 09:54:50.025076')'

The empty () suggests empty lists passed as raw parameters, which pymysql renders as an empty tuple. Not checked: whether the insert is in the test or in the migration 20261031190604_jour_fixe_series. If it is in the migration, MariaDB operators hit it on a real upgrade, and the migration must be fixed. Say which it is. Blocks the deploy candidate.
