KIR-QER-Nezirov – Supplement II: QER–KIR Bridge & Compact Objects

This Supplement II to the KIR Complete Treatise (Kinetically-Induced Reality) accomplishes two complementary objectives: it establishes a complete formal mathematical bridge between the stochastic possibility space of QER-Nezirov and the scalar interaction density field σ of KIR, and it derives quantitative, experimentally testable predictions for five classes of compact astrophysical objects. Part I — The QER–KIR Bridge identifies the σ-field as the physical collapse density of the QER possibility space: high σ corresponds to dense crystallization of reality, low σ to an open, indeterminate possibility space. All four bridge coefficients are derived parameter-free from two physical fixed points (σ = 0: cosmic void; σ = 1: event horizon) and a minimality principle — they are no longer postulated as in V1.0. The resulting structures are: a Fokker-Planck equation for the probability density P(ω,t) with σ-modulated diffusion D(σ) = D₀·(1−σ) and drift μ(σ) = μ₀·σ; an equivalent Langevin stochastic differential equation; a path integral with KIR weight factor f(σ) = 1/(1−σ); and the predictability exponent x(σ) = 2−σ, which quantifies the continuous transition from quantum indeterminism (x = 2, σ → 0) to classical determinacy (x = 1, σ → 1). The parameters D₀ and μ₀ appear only in the ratio SNR = μ₀/√D₀, reducing the bridge to a single effective calibration parameter. Part II — Compact Objects applies the KIR framework to neutron stars, pulsars, magnetars, white dwarfs, and quasars. All objects are characterized by their surface σ-value, time dilation factor √(1−σ), collapse rate Γ(σ), effective fine-structure constant α_eff(σ) = α₀·(1 + γ_em·σ), and predictability exponent x(σ). Three genuine, γ_em-independent falsification tests are identified: (1) a Shapiro delay correction of +8.5% relative to General Relativity in double pulsar systems, arising from the nonlinear σ-saturation term; (2) a radial variation of the fine-structure constant Δα/α ∝ 1/r across quasar accretion disks, testable via spatially resolved iron K-line spectroscopy; (3) a cos²θ anisotropy of the effective coupling in magnetars due to the directional σ-gradient of the magnetic field energy density. White dwarfs (σ ~ 10⁻⁴) serve as weak-field null-test objects, confirming KIR's recovery of the linear Newtonian regime. The full experimental test program identifies ATHENA (Δα/α ~ 10⁻⁵ at neutron star atmospheres), FAST/SKA (Shapiro correction in binary pulsars), Chandra/JWST (quasar radial profile), and IXPE/eXTP (magnetar polarimetry) as the relevant instruments.
