Follow-up to PR #38. That PR fixed the SHELL line (replaced ${{ github.event.head_commit.message }} with git log) but kept a comment mentioning the expression literally. Comments are not exempt: the runner template engine interpolates ${{ ... }} BEFORE bash sees the script, so the multi-line commit body still ended up injected mid-comment and broke bash parsing on the next line. Symptom (still fired on PRs #40-#45 even after PR #38): /var/run/act/workflow/12.sh: line 32: syntax error: unexpected newline ❌ Failure - Update badges and version Fix: rewrite the comment without the literal expression. The other 3 references to head_commit.message in this file are inside job-level if: contains(...) checks which are evaluated server-side as booleans, not interpolated into shell — those are safe and unchanged. Lesson for the verifier checklist: when fixing template-injection bugs, search the WHOLE FILE for the expression including comments, not just active code lines.
