Well a lot of this is simply published. Like, from reading a bill, agency rules, memos, whatever. Most of it is not hidden, except by...boredom? Like you had to be interested for whatever reason to go looking for it. Or embedded somehow in one of the institutions where you can see what the people at the bottom of the institution can see, without wanting to make a career out of it. Since if you decide that, then there's no incentive to notice.
