How does the ECM know that it's "fixed?" Does it ask me for the receipt for the O2 sensor? Does it make me sign an affidavit? Take an oath?

FLO is watching
The ecm wont give the option to clear them. You would have to go through so many driving cyclrs without a fault for the ecm to automatically clear the code. Kind of how the srs codes work now.

It has to pass the monitors.
That will be hell in some climates. Already, Ohio will pass a car that hasn't run its evap monitor, because there can be periods of months where the climate won't permit the test to run. So what do you do if you can't reset the computer but it's January and the air temp has to be over 50 degrees or something?
This, incidentally, is where you get "intermittent" check engine lights. The specific case is, the fault is still present, but the conditions did not exist for the test to run over ~40 drive cycles (cold start to full operating temp), and since the monitor did not fail in that time, the light automatically goes out. Until the first time conditions ARE present for the monitor to run, and then it fails and sets the light again. "But the light went out three months ago and now it's back on." "That's because three months ago it got COLD and now it's warming up again."
So, the cheapass way to "fix" an evap leak is to make sure the tank never is between 1/8th and 7/8ths full. Because cheapass, we're going to assume that it's kept below 1/8th instead of above 7/8th...
