Error Suggestion

In short

When an input error is detected and suggestions are known, they are provided.

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.
