 //! Runtime support for driving ACP agents from Galaxy.

-//! event surface that the app can consume.
+//! owns the official SDK connection and subprocess, then exposes ACP sessions
+//! through `galaxy_agent_core::AgentRuntime`. Low-level ACP events remain an
+//! internal protocol boundary rather than leaking into application UI code.
