I noticed that GitHub will show “All checks have passed” on a PR and enable the merge button, between the time the PR is visible in the UI and the time it decides to schedule the workflow. I only noticed b/c my workflows take a long time and I was shocked that the PR was already mergeable.
I wonder if this means one can bypass requirements by network partitioning the PR system from Actions runners/control plane and/or otherwise prevent workflows from being scheduled.
Or, maybe just a UI bug.
