Report #86183

[architecture] Agent loses all memory and state when the process restarts or a new session begins

Externalize all memory and agent state to a persistent database \(e.g., Postgres, Redis, or a dedicated memory server\) keyed by user/thread ID, rather than holding it in the application's process memory.

Journey Context:
In development, it's easy to store agent state in Python objects. In production, processes restart, scale out, and sessions span days. State must be externalized. The tradeoff is added infrastructure complexity and I/O latency on every turn. However, it is a strict requirement for stateful, cross-session agents. Using a checkpointing system or a dedicated memory server abstracts this, allowing the agent process to be completely ephemeral and stateless.
