What was unclear about it?


Well, the controller thought it was discretionary. That you and she
disagree tends to indicate it's not clear.



I'd never infer discretionary descent unless it was explicitly stated by
the controller.


The controller does not have to state "descend at pilot's discretion" in
order for the descent to be discretionary. A descent clearance with a
crossing restriction is a discretionary descent. A cruise clearance to an
airport without an IAP is a discretionary descent.



I'd say the clearance
unambiguously required vacating 7000 (before amendment).


What amendment? The pilot asked the controller to verify that the descent
was at pilot's discretion and the controller responded in the affirmative.
