actions/checkout v6+ refuses to check out fork heads in pull_request_target workflows unless allow-unsafe-pr-checkout is set. HYF assignment graders need that opt-in to run .hyf/test.sh on student forks and post the score comment. Pin the head repo explicitly and drop persisted credentials from the student tree.

actions/checkout v6 refuses fork heads under pull_request_target. Pin the reusable grader to the fixed fork branch until HackYourFuture/github-actions#4 lands on main. Co-authored-by: Lasse Benninga <devops.pipeline@example.com> Co-authored-by: Cursor <cursoragent@cursor.com>

The grader pointed at fix/allow-unsafe-pr-checkout-for-autograde, a feature branch whose upstream PR (HackYourFuture/github-actions#4) was closed without merge. The pin is therefore permanent, but the name reads as disposable, and deleting it would silently break grading for weeks 11, 12 and 14 at once. stable/hyf-auto-grade points at the same commit (346f1ae8). No behaviour change; this is a rename plus a comment that tells the truth. Co-authored-by: Lasse Benninga <devops.pipeline@example.com> Co-authored-by: Claude Opus 5 <noreply@anthropic.com>
