Impact
REQUIRED: Choose either Tooling Impact or Customer Impact (or both). At least one checkbox must be selected.
Tooling Impact
Removes deprecated GitHub Actions workflows (AssignPrs, createReminders, processReminders, markdownLink) and pins script downloads to specific commits for OpenSSF Scorecard compliance. Affects CI/CD security and workflow automation.
Customer Impact
Regression
REQUIRED: Check exactly one box.
This is not a regression.
Testing
Verified by running affected workflows in fork. Confirmed builds complete successfully and deprecated workflows are removed.
Risk
REQUIRED: Check exactly one box.
High risk as it modifies build infrastructure by removing deprecated GitHub Actions workflows and updating script download pinning. However, necessary to maintain security posture and remove unused automation. Changes validated in master branch since October 2025.
