A few change requests.

Some of these might not be super easy, so lmk if the time investment is not wroth it in your opinion.

Also, I added @commoddity as a reviewer instead of @bryanchriswhite so he has some visibility into the test framework.

LGTM!

The CI will now also run the e2e tests on devnet, which increases the time it takes to complete all CI checks.

You may need to run make trigger_ci to submit an empty commit that'll trigger the tests.
