This merged addendum consolidates and supersedes previous corrigenda to QuantumEntanglement Origin of Gravitational Dynamics: The Θ-Field Theory. It (i) makes theinflationary sector quantitatively explicit using a minimal α-attractor plateau potential, (ii)fixes the power-spectrum normalization to the observed scalar amplitude, (iii) restates theCassini/Shapiro-delay bound as a direct constraint on the conformal coupling λ, and (iv)clarifies the current experimental status of the theory. In particular, it is shown that allpresently testable deviations from general relativity are strongly suppressed by solar-systembounds, placing the Θ-field in a viable but currently non-detectable regime. The addendumtherefore establishes internal consistency and non-exclusion, while explicitly identifying theabsence of a present-day experimental proof.
