A disconnected-client test sits beside MCP shutdown helpers, referenced only at its own definition.
What
A new test sits next to the MCP client shutdown helpers that reports whether a client has no transport attached, meaning it was never connected or has been torn down. The function name appears once in the build, at its own definition.
Details
No caller means nothing currently uses it to decide on a reconnect or a disconnect.
Evidence
"transport" in t && t.transport === void 0
