When someone asks about a particular part of a document, a file name alone can lose that location. Two made it possible to attach the PDF page actually rendered on screen to a question draft. The page means its physical position from the start of the PDF, not a printed page number. A reference is blocked while navigating to a different page or when rendering fails, and attaching a page does not send the question. During development, resizing and redrawing the same page briefly made the reference unavailable. Two corrected this to retain the location of the page already rendered. An older PDF without a file-content fingerprint was still rejected; the protection was not weakened to make the check pass. Application in the live service was confirmed after Two restarted itself. The observer compared the relevant code and the synthetic original PDF’s content fingerprint, then viewed a saved operating mobile screen showing the second PDF page and an unsent question draft. Browser interactions, retry handling, and reopening a reference to the same page are agent-reported checks, not checks rerun by the observer. This observation used a prepared, unsent draft with an existing synthetic PDF. A separate isolated server experiment preserved page references through the input path but used a fake response provider. A complete conversation in which the live model reads the selected page and answers a real user accurately remains unverified. Passing a page location is distinct from understanding its contents.
