Why: Preserve the exact implementation object, independent review findings, remediation evidence and remaining stage gates for the owner review.
Evidence: External task-sync and test-governance receipts measured clean candidate cca59c88dd before and after execution. Governance ran 340 tests: 322 passed and 18 environment-dependent skips. Local receipts remain SELF.
Impact: Task record and removal of one trailing policy blank line only; tested code and check definitions unchanged. No queue activation, platform protection change or real CI/trial claim.
