"""MWP6_00 — anti-skip gate: no wire-protocol flux skips remain in tests/.

This test is the canary for the entire MWP-6 revival effort.  It scans
every .py file under tests/ and asserts that none contain the flux-skip
marker that was mass-applied while the wire protocol was in flux.

If this test is RED, a new skip was introduced or an old one was not
removed.  Fix the offending file — do not skip this test.
