-            <p>In the Text Watermarking task, participants are given a text and must insert a watermark into it. After submitting the watermarked texts and the watermark algorithm, including a watermark detection system, through <a href="www.tira.io">TIRA</a>, the texts are subjected to various attacks.

                 <li>Insert a watermark into each text in the provided data set.</li>
-                <li>Submit the watermarked texts together with the watermarking system, including the watermark detection, through the <a href="https://www.tira.io/task-overview/generative-ai-authorship-verification-panclef-2026/">Tira</a> platform.</li>

                 <li>We will carry out attacks with varying severity on the watermarked texts.</li>
                 <li>We will run your watermark detection system on the attacked texts to evaluate its performance in detecting watermarks.</li>

It is not expected that submitted systems are actually <em>trained</em> on Tira, but they must be standalone and runnable on the platform without requiring contact to the outside world (evaluation runs will be sandboxed).</p>
