+## Architecture Overview

+ClawScope is a local-first desktop control plane: React renders the memory, configuration, and evolution workspaces; Tauri IPC forwards UI actions into the Rust command layer; and Rust talks to OpenClaw Gateway over WebSocket to access agents, memory, configuration, and evolution targets. Local JSON storage only keeps connection identity, endpoints, audit history, and snapshots for reconnect, traceability, and rollback.
