Module surface 

Surface-relevance gate for evidence modifiers.

Detects when a SameStatus Contradictory is mis-surfaced — i.e., the technique declares Status as its primary surface, the SameStatus arm fired (statuses are equal), but the body or headers show a significant differential. The actual oracle signal is on a non-status surface, so the status-equality Contradictory conclusion is wrong and the outcome should downgrade to Inapplicable.
