[architecture] Agent loses state or hallucinates previous session context across new sessions

Enforce strict statelessness in the agent runtime. Persist memory as immutable append-only logs. At the start of a new session, reconstruct the agent's context window strictly from the retrieved memory logs, never assuming prior context window continuity.

Journey Context:
Developers often try to keep agent processes alive or serialize the whole context window to disk. This leads to stale state, token bloat, and hallucinations when the session resumes. Append-only logs \(Event Sourcing\) allow deterministic reconstruction of state and clean separation of long-term memory from the current active context.
