+/// The shape that actually exists in the wild, found by the SKILLS session in three
+/// workshop directories: `active: true` and a `server:` name, with NO
+/// `intersystems.servers` map at all — because Server Manager keeps the server
+/// definition in USER-scope settings, which this binary does not read.
+///
+/// `a_named_server_with_no_matching_entry_is_not_configured` covers the neighbouring
+/// case (map present, key absent). This one takes a different branch —
+/// `intersystems_servers.as_ref()` yields `None` before `.get()` is ever reached — and
+/// the two must not be assumed to agree just because they should.
+///
+/// It must resolve to NotConfigured so discovery falls THROUGH to the scans. Anything
+/// else would make 0.17.0 break every workshop directory: under the new precedence this
+/// entry is reached at step 4, ahead of the port scan that currently serves it.
