Documents the failure mode where issuing a synchronous `ssh host reboot`
through Claude Desktop's shell MCP poisons the local MCP transport when
the target severs its session before responding cleanly — eventually
force-disconnecting every MCP at once. Covers diagnostic chain, recovery,
fire-and-forget reboot patterns, and worked example from the 2026-05-10
majorhome AMD-card reboot.
