"""Audit log entries record the acting user_id.

Schema: the ``audit_log`` table has a ``user_id INTEGER`` column added
by migration 0011; the SQLAlchemy ``AuditLog`` model itself does not
declare it yet, so ``append_event`` cannot pass it through. These tests
fail before the model + dataclass are updated, and pass after.
