The situation
Thursday 17 September 2026. Nare wants to drop the lab sync note into a chat by name, without waiting for the model to search. Her desktop assistant's picker lists only what a server offers as resources, so the notes server needs addresses: notes://index for the list and one per note, such as notes://lab-sync-2026-09-02.
The catch: next to notes/ sits notes-private/, with reviewers' comments that must never reach an assistant (made up, added in this lesson). An address the client chooses is one an attacker can choose too.
