One is half of two.
“Half” means one of two equal portions. Divide two into equal whole-number portions and each portion is one.
An explanatory middle is present: dividing into two equal parts. Unlike a difficult proof, that middle is immediately available.
The difference between first principles and fiṭriyyāt is therefore no middle term required versus a middle term present without a search, not simply whether learners answer quickly.
