This is the Bose permutation symmetry of the 3 quarks in the proton's 3-quark Borromean closure: the QLF reading is that exchanging any two quarks gives a state physically indistinguishable from the original (modulo flavour labels), and there are exactly `|S_3| = 6` permutations of 3 indistinguishable objects. Standard group-theoretic fact. -/ def S3_order : ℕ := 6 /-- **Number of independent angular parameters** in the proton's chirality-hiding configuration space.

The 2 chirality- mixing angles rest on the QLF reading that the gauge-fold has a 2-axis (real/imaginary) chirality-mixing structure per Hermitian- conjugate pair (Proton_Resonance_R_e.md §6 honest scoping); the exact factor of 2 needs first-principles validation from Borromean topology, an open sub-target. -/ def hidden_chirality_angles : ℕ := 5 /-- **The Lenz factor**: `|S_3| · π⁵ = 6π⁵`. The product of the permutation-symmetry order and the π-per-angle integration measure over the 5 hidden-chirality angles. Each independent angular integration contributes a factor of π under the spherical-harmonic-style integration; the `3!` quark permutation prefactor accounts for Bose symmetry of identical-ish quark constituents.

Under the chirality-hiding-resonance reading (Proton_Resonance_R_e.md), the proton's 3-quark Borromean closure hides individual quark chirality from electron-annihilation probes; the electron mass is the resonance threshold that threads the needle between chirality-resolution and atomic binding. The depth ratio `R_e = R_p · 6π⁵` follows from this resonance condition, and gives the inverse mass ratio: m_p / m_e = R_e / R_p = |S_3| · π⁵ = 6π⁵ where the last equality is the Lenz factor. -/ noncomputable def mass_ratio_QLF : ℝ := lenz_factor /-- **Lenz factor structural identity**: `lenz_factor = 6 * π⁵`.
