# Signed proof the agent stayed within budget

What a principal actually wants at the end of a period: not a dashboard, but a document they can verify and keep. Lists every counted spend, the budget, the total, and whether it stayed inside. Every spend listed was VERIFIED ON-CHAIN before counting, and the figure is what the destination chain showed arrived — not what the agent reported. It certifies adherence to a ROBYN budget. It does NOT certify the agent spent nothing elsewhere, because Robyn can only account for money that moved through Robyn — `doesNotCertify` says so in the payload rather than in a footnote, since a principal reading it as proof of total spending would be badly misled.
