Use cases

Start where money already moves without anyone deciding.

You do not need an agent fleet to have this problem. A refund service, a payout run and an ops tool all spend money nobody approved, one movement at a time. These are the places a rule in front and a record behind pay for themselves first.

Where teams start

Two places, both measurable in a month.

Pick the one where somebody in finance can already tell you the number.

Pick the one that already costs you money.

The sandbox is the whole engine in test mode, with no card. Model the policy you wish had been running last quarter and see what it would have stopped.
