"""TaskService._audit_events_for — the rejector-attributed audit event selection.

A transition always emits the generic ``task.<status>``; a reviewer bounce to
needs_revision additionally emits ``task.qa_fail`` / ``task.pr_fail`` keyed on
the acting role, so the per-agent rework scorecard can attribute the rejection.
