We analyse vacuum radiation in the Entropic Time Dilation (ETD) framework using three complementary effective models in 2+1 dimensions: (i) a linearised scalar S-field on flat spacetime, (ii) an EM-like U (1) vector potential with ETD clock-weighting, and (iii) a gauged Abelian–Higgs vortex–antivortex simulation (ϕ, Aᵢ) seeded from ETD one-dimensional BPS vortex profiles. In the scalar and vector cases, a localized source follows a prescribed accelerated trajectory, and the vacuum response is governed by wave equations with acceleration-weighted source terms. We obtain Larmor-type radiation laws with coefficients CS ≈ 0. 025 and Cᵥec ≈ 0. 028 in dimensionless simulation units. We then incorporate explicit dynamic Θ (S, ∇S) weighting directly into the time evolution of the gauged Abelian–Higgs system. In near-BPS and Type-I regimes the vortex–antivortex pair annihilates, transferring ∼80–85% of its post-relaxation energy into a single outgoing gauge-plus-scalar wavepacket. In 3+1 dimensions, using a Maxwell (Yee-style) GPU harness and consistent far-field probe geometry, we (a) measure helicity purity of the forward-emitted packet via the Riemann–Silberstein field, obtaining hRS ≈−0. 89 in a forward cone, (b) observe ladder consistency N=f/fETD, local ≈1 at the dominant packet peak, and (c) construct an energy-closed frequency-resolved allocation enabling an action normalization with photon-number spectrum nₜotal ≈1 for the packet aperture used throughout the work. Finally, 3+1 Larmor experiments verify the expected doubling of the vector coefficient when driving two orthogonal transverse polarizations, with Cᵥec (xy) /Cᵥec (x) ≈ 2 in both forward-cone and full-sphere apertures. As an empirical consistency check, we show that the ETD acceleration driver Iₐ ≡ ∫ aₑff (t) ² dt extracted from published single-bubble collapse traces covaries strongly with photon yield per flash (log-correlation ≈ 0. 981; Spearman ρ=1. 000) across the reported ambient pressures. Within the effective modelling level used here, these results close the classical diagnostics (radiation law, emission channel, helicity/polarization, ladder locking) and the classical-to-quantum action normalization employed in this manuscript.
