Claim. The two ways the oracle premise can fail license different readings: missing the registered margin is consistent with the validity-rarity limit without proving it, while failing the acceptance gate says nothing about whether perfect validity information helps, and either way no positive label can be attributed to validity filtering.

Type. mechanism · Support. stated

Holds when

• Both failure modes are registered in advance rather than drawn after the outcomes were read.
• The distinction governs what the paper may say, not what the filter did.

Source quote

If the oracle premise fails, the reading depends on how. If the oracle contrast misses the registered margin, perfect validity information was not shown to help at that margin, which is consistent with the validity-rarity limit without proving it. If instead the oracle fails its acceptance gate, part of its training set was filled from rejected candidates, and that event says nothing about whether perfect validity information helps. Either way, no positive label can be attributed to validity filtering, weighted or not.
