Critical fix for installed systems. v1.0.0/v1.0.1 generated agent MCP configs that spawned bun <bundled source> — a command no installed machine can run (no bun, no repo on disk). Agents therefore could never call task_complete, and cards hung in working forever. The installed binary now serves the MCP sidecar itself (rvmp mcp-sidecar, wired automatically), and rvmp doctor performs a live sidecar handshake so a broken MCP path can never again fail silently.
If you installed 1.0.0/1.0.1: re-run curl -fsSL https://codegent.io/install | sh (or rvmp update), then restart the daemon.
