Time is short to dispel the semantic confusion between discovering and creating.
A proof does not give rise to the equivalence between fixed-point sensitivities and KKT sensitivities; it demonstrates it.
This equivalence already existed, independently of any formalization, and is not manifested through an act of mathematical substitution.
Confusing a proof with an act of creation dilutes fundamental understanding, as if a correlation analysis created a link between assets rather than revealed it.
