+PyJHora issue #17 is a UI/encoding issue with a general mismatch report, not VP Jain calibration. The benchmark now pins `V4.8.7` / `ca22995709bd60e371e7820a1a5efc80ce4cf821` and the exact test function URL. Treat its AGPL numeric expectations as a candidate replay, never independent formula arbitration.
