It's worth noting the difference between Budget & expenses since families normally blur the two. Budgets are the plans developed by the President and approved by Congress, and expenses are what actually get spent during the year-- and they vary widely.

DOGE's unique approach is to use the Treasury as the "chokepoint" for telemetry so they can cluster and classify all of the transactions .

Imagine a massive microservices platform with 10k services and you want to know which ones are viable ( cost/benefit). Rather than survey all 10k, you would surveil a router or LB chokepoint to measure the input & output of all 10k services. That seems to be their approach with the treasury.
