The beauty of it is that it can embed a certain logic in an abstract way in an equation, allowing reference to the logic, or its elements, just by way of referring to the equation, and its elements...
You may be unstalled (i.e. your wing is flying, producing lift & allowing control) but not have a CI big enough to support your weight. Then, you're descending. But no more stalled.
Exactly!
My point is : Speed is a consequence. AoA is what matters.
The explanation helped seeing that I've missed your implicit reference to the speed vector's scalar (magnitude) as a constant element, with the changes of the vector's direction coinciding with the AoA changes, and vector axial components changes.
With the rephrasing, I think we're in sync (unintentional rime).
The "speed change” I was referring to “is a consequence of change of AOA" , with both energy conservation and momentum conservation playing their roles.
