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

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
