V39 Gate 9: Stabilize prior gate proof posture

Allow the Gate 8 operational telemetry readback predicate to remain valid as the V39 roadmap advances to later gates while still requiring the Gate 8 closure anchor.\n\nValidated with check:v39-gate8, check:v39-gate9, V39 draft spec-family check, and git diff --check.
