+/// What a model can do and what it is for are two questions, and they used to be answered by two
+/// pieces of code, each walking the same name with rules of its own. While both existed, the tests
+/// here held one against the other. The marker list is gone now, and with it the comparison: the
+/// corpus-wide check moved into the snapshot, which carries the kind of every model in a column of
+/// its own.
 ///
-/// The day the call sites move to the profile, the marker list goes and the test below which asks
-/// it goes with it. What stays is the first test: the examples say what each name is, in words a
-/// person can check against a model card.
+/// What is left says what a name is, in words a person can check against a model card -- and holds
+/// the handful of decisions where the rules deliberately answer something else than the markers did.
+/// Those stand in the corpus next to the name, with the reason.
