Sommario:
- <p>Papers I–II established a no-go theorem: no local kinetic modification can</p> <p>stabilize a hilltop with V’’(C₀) < 0. This paper identifies the minimal evasion within</p> <p>the RCD framework by lifting the decoupling approximation to include leading-order</p> <p>backreaction from the sub-coherential microstructure. We work in the semiclassi-</p> <p>cal Markovian approximation of a Caldeira-Leggett bath coupled to the coherence</p> <p>field. Integrating out the bath produces a static Coleman-Weinberg correction (α₀)</p> <p>and a dynamical Markovian piece (Λ = αγ₀/Γ_eff). Within the class of Markovian</p> <p>Caldeira-Leggett completions considered, α₀ + Λ > v is necessary and sufficient for</p> <p>linear stabilization. We do not claim a UV derivation of the effective coefficients; we</p> <p>identify the minimal ingredient, declare the regime of validity (including the weak-</p> <p>backreaction parameter ε <span>≪ </span>1), and verify numerically. Non-adiabatic dynamics (fi-</p> <p>nite Γ/H) demonstrates that the stabilization is an active dynamical process with a</p> <p>characteristic three-phase transient, not a static reparametrization.</p>
