  # ── Python 3.14 compatibility gate ──────────────────────────────────
  # 3.14 is the documented development runtime (AGENTS.md) and the version
  # where the mlx C-extension segfault was diagnosed (addendum 2026-06-09).
  # We run it as an experimental, non-blocking job so 3.14 regressions
  # (e.g. a new C-extension imported at module top-level) surface in CI
  # without breaking the main gate until the stack is confirmed stable.
  # The test_import_audit suite is the key defense — it verifies no
  # C-extensions load at provider import time.
