A module's broker account is scoped to what it declares it emits and consumes. A
tool call needs a reply queue, which that scope does not cover and should not. So
the account is right, the request is reasonable, and no account exists that can
make it — asking a module its own question, from its own container, with its own
credential, is refused.
It matters because a module's tools are its operator-facing surface: the
catalogue serves the five questions it exists to answer and nothing can reach
them. It is also why a running module keeps being mistaken for a working one — a
test that cannot ask anything checks a container is up, and that substitution has
hidden two faults this week.
