Report #51922

[architecture] Agent assumes facts from a previous session are true in a new session without verifying, leading to hallucinated cross-session state

Tag all persisted memories with session ID, timestamp, and source. During retrieval, explicitly instruct the LLM to treat cross-session memories as 'unverified historical context' rather than absolute current truth, and verify volatile state before acting.

Journey Context:
When an agent wakes up in a new session, its context window is empty. If it retrieves a memory saying 'The server is down', it might act on it immediately. But the server might be up now. The fix isn't to discard old sessions, but to treat memory as a belief rather than a fact. By forcing the agent to verify stale cross-session state \(e.g., running a quick API check\) before taking irreversible actions, you prevent cascading errors based on outdated assumptions.
