Everyone selling you an agent has a demo. Nobody hands you an audit. Holdout builds a working copy of your system from data you already have, lets the agent do the job there, and then checks every record it touched against what should have happened — with points off for damage. It keeps re-running after you deploy, so a quiet model update can't silently break what worked last month.
A working copy of your system, built from logs and exports you already have — and proven faithful by replaying a day of real traffic against it.
