Построение тензорного источника ODTOE-гравитации: тензор энергии-импульса T_μν как функциональная производная действия наблюдателя S_obs=∫B²(1−σ)Λ√−g d⁴x по обратной метрике g^μν. Космологическая постоянная Λ как замкнутая функция глобальной когерентности S*=0.169676. Построение SYNC-проектора P_{O,SYNC}: H→C. Лемма L7 об идемпотентности P²_{O,SYNC}=P_{O,SYNC} доказана без предположения уравнения Эйнштейна. Лемма L8 о законе сохранения ∇_μT^μν=0. Замкнутая форма χ_Λ(S*)≈0.082201 даёт Ω_Λ≈0.688647 — согласие с Planck 2018 в пределах 0.05σ без подгонки.

Construction of tensor source of ODTOE gravity: stress-energy tensor T_μν as functional derivative of observer action S_obs=∫B²(1−σ)Λ√−g d⁴x with respect to inverse metric g^μν. Cosmological constant Λ as closed function of global coherence S*=0.169676. SYNC projector P_{O,SYNC}: H→C construction. Lemma L7 on idempotency P²_{O,SYNC}=P_{O,SYNC} proved via four sub-lemmas without assuming Einstein equation. Lemma L8 on conservation law ∇_μT^μν=0. Closed form χ_Λ(S*)≈0.082201 giving Ω_Λ≈0.688647 — agreement with Planck 2018 within 0.05σ without fitting. Consistency with Jacobson horizon thermodynamics.

摘要

ZH

ODTOE引力张量源的构建:应力-能量张量T_μν作为观察者作用量的泛函导数。宇宙学常数Λ作为全局相干性S*的封闭函数。SYNC投影器P_{O,SYNC}构建。幂等性引理L7证明。守恒定律引理L8。封闭形式χ_Λ(S*)≈0.082201给出Ω_Λ≈0.688647——与Planck 2018在0.05σ内一致。
