How does Ramp Stack keep a human in the loop and maintain audit visibility over what its agents do?

A core design goal of the rollout is that Stack is secure, auditable, and keeps a human in control. Stack shows its work throughout the entire process, giving full audit visibility, and the user is the one who clicks 'post' to QuickBooks before any entry actually hits QBO — so firms can be confident agents won't take an action they aren't expecting. This is framed as a differentiator from other AI-for-accountants tools on the market that don't build in human-in-the-loop controls the same way.
