What Is New and What Is Not

What is new

The empty set ontology of the pre-state. Quantum mechanics is not a feature of the universe — it is the universe’s foundation. The pre-state IS the empty set. KS-Q.10.

Linearity from R + ℂ + EH. The bridge construction. KS-Q.7.

Complex amplitudes from the Lorentzian signature. The conditional derivation. KS-Q.4.

The loop and defragmentation as the forgetful functor. The structural argument for R-preservation. KS-Q.5.

The σ ↔ conjugation proof. The Born rule’s structural foundation. KS-Q.6 CLOSED.

Entanglement as unbroken pre-state. Separateness as experienced but not fundamental.

The Born rule from Axiom S + Gleason. Conditionally closed. KS-Q.1.

The Schrödinger equation from Wigner + Stone applied to the derived Hilbert space. The form forced. ℏ identified.

The complete chain from 1:1 + 1×ε to the Schrödinger equation, with every link declared.

What is not new

The mathematics. Stone’s theorem, Wigner’s theorem, Gleason’s theorem, the Cauchy-Schwarz inequality, the Peter–Weyl theorem — all standard mathematics.

The empirical content of quantum mechanics. Every experimental result remains valid. The derivation produces the same predictions as the standard postulates because the postulates are derived consequences.

The wave function. The Hilbert space. The complex amplitudes. The unitary evolution. All present in standard QM. Here they are derived rather than postulated.

The interpretive structure does change. The wave function does not collapse. The pre-state breaks. The observer is the now at a site of coupling. Separateness is not fundamental. But these are interpretive consequences of the derivation, not new physical postulates.
