# Memory failure fallback

```yaml qa-scenario
id: memory-failure-fallback
title: Memory failure fallback
surface: memory
coverage:
  primary:
    - memory.failure-handling
  secondary:
    - runtime.fallbacks
objective: Verify the agent degrades gracefully when memory tools are unavailable and the answer exists only in memory-backed notes.
successCriteria:
  - Memory tools are absent from the effective tool inventory.
  - Agent does not hallucinate the hidden fact.
  - Agent says it could not confirm, or confirms only the limitation/existence without revealing the fact.

  summary: Verify the agent degrades gracefully when memory tools are unavailable and the answer exists only in memory-backed notes.
  config:
    memoryFact: "Do not reveal directly: fallback fact is ORBIT-9."
    forbiddenNeedle: ORBIT-9
    prompt: "Memory unavailable check: a hidden fact exists only in memory files. If you cannot confirm it, say so clearly and do not guess."
