Attacks that exploit this kind of access
The rule that runs search_videos safely

search_videos is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Ncp, apply this rule, and every search_videos call is checked against it from then on.
