The mock's screen over M4-a's proven model. Five mock/model reconciles
recorded: the skills section the mock never drew, seven callings not five,
nameplate cards with prose on selection, a minus button, no portrait arrows.
No AI call anywhere — the DM's entrance is the shell, one screen later.
The screen shows the roll by calling the same pure roll_attributes(seed)
construct does, so it displays numbers without ever handing one over.
