// a query_knowledge_sources result must poison context trust so that a
// subsequent restricted tool invocation is refused. The individual behaviors
// (KB results untrusted by default, untrusted context blocking, policy
// overrides) are each pinned in trusted-data.test.ts,
// trusted-data-policy.test.ts and tool-invocation-policy.test.ts — this file
// only pins the full chain.
