+## Bounded Stateful Listeners
+- Pure tools remain stateless.
+- Stateful capabilities (e.g., calculator memory, game state) store data per thread path UUID.
+- Ensures isolation across conversations, automatic cleanup on idle, and minimal mutable state.
+- Handler closes over or receives UUID for access — still oblivious to readable path.

 The AgentServer message pump processes individual messages through a single, linear, attack-resistant pipeline. The outer dispatcher runs a continuous async loop, draining per-thread message buffers (queues) until empty — enabling persistent, branched reasoning without artificial limits.
