Spot on. BEAM is great at surviving process crashes, but if the whole cluster goes down or you redeploy, that in-memory state evaporates. It's not magic. For agents that might hang around for days, pure Elixir isn't enough, you still need a persistence layer. The ecosystem is catching up (Oban Pro, FLAME), but in reality, we're still building hybrids: fast actors for active chats and a good old DB for history and long-running processes
