MedRouteGuard: companion artifact for Every-successful-replay route admission changes first-token latency rankings in clinical question answering

Lightweight offline companion artifact for “Every-successful-replay route admission changes first-token latency rankings in clinical question answering”, prepared for submission to Journal of Medical Systems. MedRouteGuard demonstrates four-clause route admission, clock-retaining fallback, fixed-candidate replay, separate overall acceptability voting with safety adjudication, paired statistics, and generation of tables and figures. The package includes pinned public-source snapshots and synthetic fixtures, with deterministic simulated observations for the offline demonstration. Run make demo and make verify; no paid model API or API key is needed.
