Module dispatch 

Host-mode dispatch helpers.

Provides run_via_pool and continue_via_pool which orchestrate worker subprocess spawning, UDS connection, registry persistence, and response forwarding.

Crux invariants enforced here

• (MCP thin proxy IPC boundary): all host_mode=true calls reach a worker subprocess via PoolClient over a Unix domain socket. The MCP-internal [SessionRegistry] is never touched on this path.
• (Registry reconnect across restarts): every successful run_via_pool call persists the session entry to registry.json via with_registry_lock before returning. A restarted MCP process can rediscover live workers from that file.

Functions

continue_via_pool

Reconnect to an existing pool worker via its registry entry and forward a Continue request.

run_via_pool

Spawn a worker subprocess, connect via UDS, proxy a Run request, and persist the session entry to registry.json.
