Why the magical dualism? Since the magic ability has been confirmed genetic and not external in the earlier testing with Draco, a "repaired" wizard will remain a wizard.

There's a genetic marker that the Source of Magic recognizes. The gene is still there, but the magic may not be. What wizards believe to be the soul leaving might be the Source of Magic withdrawing its power.

Sure, that makes sense. But why would it not come back once the person is alive again?

Because a stateless system is always simpler than a stateful one.

If it assigns magical ability to living brains with wizard genes, that is strictly lower Kolmogorov-complexityi than identifying a wizard at birth, tagging them and then withdrawing power when they 'die'.

(Stateless means no hidden variables; everything can be decided locally.)

Examples of powerful stateless systems: The basic logic gates, the Link Layer of the Internet (barring traffic control utilities), Lambda Calculus, and others.

You seem to confirm my point. It's a basic logic gate: (wizard genes & alive) = magical ability. remembering that the person was once dead is an extra complication.
