Focus Not Obscured (Minimum)

In short

When a component receives focus it is not entirely hidden by author-created content.

How Percelia tests it

Percelia detects some cases automatically with rules; the rest needs AI or human judgment. Anything ambiguous goes to human review.

This criterion is judgment-bound and is always put to a human reviewer at Percelia, even at high confidence.
