[architecture] Agent hallucinating cross-session state by assuming context from previous runs

Never assume previous state exists in a new session. Explicitly load session state from an external persistent store \(like a database or file\) as the first action of the agent, and validate the loaded state before acting.

Journey Context:
LLMs are stateless. If an agent acts on a prompt like 'Continue where we left off', it might hallucinate progress because it has no actual memory of the previous session. The fix is to make memory loading an explicit, observable step \(tool call\) rather than implicit context, ensuring the agent operates on verified ground truth.
