Acero et al. (A (ii) transitional Euclidean ↔ infundibular geometry, with the energy-dependent brane-bulk transit probability fbulk (E) = 1 − sinc² (E/2m_π) giving ~0. 98 at 1 GeV but ~10⁻¹⁶ at optical, so GeV photons traverse the SLSN's rT2* ≈ 41, 000 AU transitional zone with near-full transit while optical sees none. The observed L_γ/Lₒpt is therefore not the emitted ratio. Five distinguishing predictions: (P1) ⁶⁰Co γ lines from forced-EC daughter chain, (P2) transient ΔYₑ<0 in late ejecta, (P3) L_γ/Lₒpt distance dependence, (P4) spectral anomaly at 270 MeV (first sinc² zero), (P5) γ/optical peak-timing offset from CSM interaction baseline. Framework provides an alternative interpretation, not falsification of magnetar. Honest scope: forced-EC overshoot by 4× suggests fbulk doesn't saturate at 3. 69% for all n-poor parents, or M (⁵⁶Ni) < 1 M⊙ in SN 2017egm; transitional-geometry amplification factor estimated as 10–100× not rigorously derived. Three predictions are uniquely framework-tagged. Zero free parameters in the forced-EC channel; the transitional-geometry channel uses the standard brane-bulk transit formula.
