Use GitHub private vulnerability reporting for Ezio2000/jharness-python when a Python runtime, provider, toolkit, packaging, or transport issue could cause unsafe execution or data exposure. Do not publish credentials, user data, or exploit details in a public issue.

Specification-level ambiguities belong in Ezio2000/jharness. The latest published Python minor line receives security fixes; pre-releases may be superseded without a backport. All three Python distributions receive the same coordinated security version.
