Vouchsafe proof
Authority here is not a permission check. It is whether the tool exists.
This page reads the browser's own tool registry on both
origins and redraws whenever it changes. Nothing below is reported by the
application; it is read back out of document.modelContext.
Toggle a permission in the panel and watch both columns move.

Try to call a question that was never allowed
A withheld permission is not a guarded tool that refuses. There is no tool. It cannot be called, guessed at, or talked into existence by anything written into a page or a prompt.
The registry, live
Read from the browser on every toolchange.
This origin registered
Borrowed across the boundary
Every change, as it happened
Appended when the browser says the tool set moved, never when this page decides something ought to have changed.
