An assistant that cannot answer still needs to help the user take a sensible next step.

Missing evidence, ambiguous questions, stale sources, and denied access are different situations. One vague error message hides those differences.

Define a response for each state, such as asking a focused question, pointing to an owner, or stopping a risky action.

Test both unsafe answers and excessive refusal. Check that the human team has enough capacity to handle the proposed escalation path.

Track unresolved questions as an improvement backlog. Useful uncertainty explains the boundary and the next step, without inventing an answer or promising unavailable support.
