Shown in a box to the one who made the quiz, after they gave a question a thumbs down and said it has an error, and Claude ("I") checked it, found an error and fixed it: the question in the list is now the fixed one. In the first person, as Tjaz's AI speaks
त्वं सत्यं वदसि, दोषः आसीत्। मया प्रश्नोत्तर्यां सः प्रश्नः संशोधितः, अधुना च यथा अस्ति तथा दर्श्यते।
