Impact

REQUIRED: Choose either Tooling Impact or Customer Impact (or both). At least one checkbox must be selected.

Tooling Impact

• Required tooling change
• Optional tooling change (include reasoning)

Optional GitHub workflow tooling update for PR label validation, retaining exact commit pinning.

Customer Impact

• Customer reported
• Found internally

Regression

REQUIRED: Check exactly one box.

• Yes
• No

This is not a regression.

Testing

The update cherry-picked cleanly and passes git diff --check. The final diff was reviewed to confirm that only the github-script action pin changes from v8.0.0 to the exact v9.0.0 commit and the existing script remains unchanged.

Risk

REQUIRED: Check exactly one box.

• High
• Medium
• Low

Medium risk because this is a major-version action update, but it affects only the label verification workflow, retains immutable commit pinning, and requires no script API changes. The update cherry-picked cleanly.
