// Mecanismul comun al controalelor negative ale Proof of Software 1.3.0: o COPIE (pos.mjs + suita + sdk-pq-sign + sdk, intr-un dosar
// temporar; depozitul nu se atinge), un paznic scos in pos.mjs-ul copiei, suita rulata pe copie. Martorul (copia neatinsa) trebuie
// verde; fiecare plantare trebuie sa inroseasca EXACT proba numita, cu suita chiar rulata (rezumatul ei exista). O ancora care nu
// apare exact o data e un esec al controlului (STRICAT), nu o linie informativa.
