Superadmin-only compare bench: runs the same question through N configured arms — the legacy
production runner and/or the v3 pass/fail runner — inline, persisting nothing, and returns each
arm's answer alongside what it cost and what it ran with.
Feature-flag defaults resolve at the PATIENT's org, so an untouched arm reproduces what
production would have done for this patient rather than for the operator.
