          Come up with a verdict on the CI test failures on pull request #${PR_NUMBER} of ${TARGET_REPO}: are they likely caused by this PR? Follow the pr-ci-triage guide (.github/workflows/pr-ci-triage.md) for the analysis.

          Write your verdict to output/triage.md as a PR comment, in the format the guide specifies and the bot voice register (.github/workflows/bot-voice.md).

          Do not post anything yourself — a later workflow step posts output/triage.md.
