+# Interactive AgentPool Runtime Architecture Diagram
+
+Added a self-contained interactive architecture diagram at
+`docs/explanation/agentpool-runtime-architecture.html`, linked from
+Reference → Architecture in the docs navigation.
+
+The diagram maps the AgentPool runtime: the four protocol adapters
+(ACP, AG-UI, OpenCode, MCP) entering the SessionPool →
+SessionController → RunHandle orchestration chain, the native
+PydanticAI agent and capability stack, the session-scoped EventBus,
+and the AgentPool service hub. The HTML is a single portable artifact
+(no external dependencies) with theme switching, node search, focused
+routes, and PNG/SVG/WebM export built in.
+
+Generated with the Archify skill against the live source tree; the same
+artifact is deployable as a standalone file or embedded in the docs site.
