+- CHECK: If `regression-check/risks.json` exists and contains `REVERT` entries, list the affected fix PRs/issues and require author acknowledgment that the reverted fix is intentional. The regression cross-reference script (`Find-RegressionRisks.ps1`) detects when a PR deletes lines that were previously added by a labeled bug-fix PR.
