The Symmetry Break (ε)

5.1 — Primordial entropy

The symmetry break is read through the low entropy of the early universe: the initial state is special, and that specialness is the break expressed as the arrow of time. [Layer 1: the low-entropy initial condition. Layer 3: its identification with ε.]

5.2 — The electroweak bridge

The electroweak symmetry breaking of the Standard Model is the established physical instance of a symmetry that holds at high energy and breaks at low energy — the structural template for 1:1 + 1×ε read at the particle scale. [Layer 1: established. Layer 3: architectural reading.]

5.3 — The electron

Observation L4 (Calculation). The electron violates the Kerr–Newman horizon condition (a² + Q² ≤ M² in geometric units) by ~10⁸⁹ — the spin term alone exceeds extremality by ~8 × 10⁸⁸ and the charge term by ~4 × 10⁴² — the maximal inverse of the compression constraint among known stable particles. [Layer 1: calculation. Layer 3: interpretation.]

5.4 — Fine-structure constant

Observation L5 (Established value + architectural interpretation). α = e²/(4πε₀ℏc) ≈ 1/137. Dimensionless coupling strength of the electromagnetic interaction. Architectural interpretation: the ratio of break strength (e²) to constraint strength (ℏc). Its value is not derived from the axiom (D3); the underivability is consistent with AP41’s structural argument that α cannot be read from within the broken system. [Layer 1: established value. Layer 3: interpretation.]
