Studio
Ask the chain.
The whole audit chain as an AG Studio report: every link and every check, with measures for money released and stopped, holds, blocks and risk. Rearrange it, add widgets, filter it, or ask the assistant (NVIDIA Nemotron 3 Ultra on Nebius) in plain words: "which agents had payments held this week, and why?". The assistant can read and change this report; it has no tool that pays, approves or edits a decision.
