Every role-local MCP spec gates itself on the service flag and skips when the surface is off, so nothing ever checked that switching it off removes it. A surface still serving after the flag went false was indistinguishable from one that was never deployed: both read as a green skip. The gating helper had no inverse at all, so there was no way to assert what a disabled service must not do.

A shared assertion now probes the endpoint with both a GET and a POST while the flag is false and fails on any answer that shows something listening. It counts 401 and 403 as listening, which is the point: a refused credential still means the surface is there. The check is transport-agnostic because the roles differ in their enabled-state probes, over SSE, Streamable HTTP or plain JSON-RPC, while an endpoint that is gone answers none of them. Each role passes its endpoint URL as a thunk, since some resolve it only once a test is running.

The coverage lint requires the registration, and derives the role set from meta/mcp.yml rather than from a filename convention, which is how the tenth role surfaced: its spec is not named like the other nine.
