Summary
This draft updates the pull request automation in this repository to avoid using
pull_request_targetfor PR-driven workflow execution.The replacement pattern keeps untrusted PR input in lower-privilege
pull_requestworkflows and moves any required repository-write actions into a separate, narrowly scoped follow-up path. Where a follow-up workflow is needed, it re-checks the pull request context before taking action so the workflow operates on the intended PR/head commit rather than trusting mutable PR state.Expected workflow shift
Notes
Opening as a draft for repository-owner review before this is marked ready. Please review the workflow-specific behavior and any repository settings assumptions before merge.
