# Local guard against accidental direct pushes to master.
#
# The "master" ruleset requires a PR + approval for the normal case (fork/external PRs).
# GitHub forbids self-approval, so own PRs rely on an OrganizationAdmin "always" bypass to
# merge once CI is green. That bypass also silently permits a stray push straight to
# master — this hook sits below the bypass layer and is the only thing that catches it.
#
# `only: ref: master` runs only while master is checked out, so a push from master always
# fails here. A deliberate direct push means temporarily removing this block by hand.
