Exact assertion
When an internal degree of freedom is removed from a coupled quadratic system, the effective response is a Schur complement. Repeating that operation produces the same triple combination that appears in Jordan theory. The Tits–Kantor–Koecher construction then packages translations, linear transformations and their opposites into a graded Lie algebra.
The stated conclusion follows inside the declared model. Reusing it elsewhere requires carrying the same object definitions, assumptions and typing.
