The corrected re-measure returned numbers IDENTICAL to the buggy one, which was
the clue. Routing was fixed, the dominance arbiter was reached, and the finding
was discarded anyway -- because every corroboration was put to the judge as a
TAINT question: "a sanitizer appears on the path: yes, does it suffice?".

For a missing authorization guard that question is meaningless. The judge
answers no to something that does not apply and the claim is dropped. All three
vibe-py access_control pairs scored both_silent this way even though the
dominance arbiter had returned model_corroborated for each of them, which I had
verified by hand earlier in the session.

Fourth instance in this feature of one shape: taint-specific behaviour applied
to every family. Sanitizer matching, config routing, family dispatch, now the
residual question. Each was exposed by a measurement rather than by a check.

The question is now phrased for the arbiter that raised it -- a guard asymmetry
for dominance, a permissive setting for constant abstraction, sanitizer
sufficiency only for taint.
