# Thread memory isolation

```yaml qa-scenario
id: thread-memory-isolation
title: Thread memory isolation
surface: memory
objective: Verify a memory-backed answer requested inside a thread stays in-thread and does not leak into the root channel.
successCriteria:
  - Agent uses memory tools inside the thread.
  - The hidden fact is answered correctly in the thread.
  - No root-channel outbound message leaks during the threaded memory reply.
