The Fermi-LAT Collaboration (Acero et al. , arXiv: 2605. 29909, A 119 authors) reports the formal systematic search for GeV emission across a curated 6-event nearby SLSN sample over 16 years of Fermi-LAT observations. SN 2017egm is the only significant detection (peak TS = 33, >5 sigma) with a Bayesian-block window of 112 days (50-162 d post-explosion) and a power-law spectrum of index Gamma = 2. 17 +/- 0. 23. The collaboration rules out the circumstellar-medium (CSM) scenario on timing grounds and on the observed Lgamma/Lₒpt ~ 1 ratio (CSM expectations < 10^-2), and favours a magnetar wind-nebula interpretation requiring either low nebular magnetization or faster-than-dipole spin-down. We respond from within the One-Octonion Brane-Bulk framework, where Paper CCLVII issued two channels for an alternative reading: (i) forced electron capture at the H+/H- shock front, with fbulk = 3. 6917% driving nuclear gamma from n-poor stable parents; and (ii) transitional Euclidean to infundibular geometry with energy-dependent transit fraction fbulk (E) = 1 - sinc² (E/2mₚi) giving near-full transit at GeV energies and effectively zero at optical. The Acero+ Table A. 2 SED shows the lowest energy bin (190 MeV) is not detected (TS = 1. 2) while the next bin (720 MeV) is the brightest (TS = 18. 2). The framework prediction CCLVII-P4 (spectral feature at 270 MeV, the first sinc² zero) is consistent with this onset-of-detection structure: bin-by-bin evaluation gives fbulk (190 MeV) = 0. 868, fbulk (270 MeV) = 1. 0000 (full transit), fbulk (720 MeV) = 0. 989. The Acero+ Bayesian-block window 50-162 d post-SN matches the CCLVII forced-EC shock-front processing window to within 10% on both edges, supporting CCLVII-P5 (gamma/optical timing offset from the CSM-interaction baseline). The total integrated gamma energy in the window is 1. 1e50 erg, larger than CCLVII's channel- (i) forced-EC central prediction (1. 2e49 erg) by a factor of ~9. 3x -- pointing to a channel- (ii) geometric amplification of A_ (ii) ~ 9. 3, which sits within CCLVII's original 10-100x honest-scope range and is now empirically anchored. Three forward predictions: CCLXX-P1 finer-binned Fermi-LAT spectral analysis at 100-500 MeV (predicts step-like TS rise centred at 270 MeV) ; CCLXX-P2 CTAO follow-up of a SN 2017egm analogue at < 140 Mpc (framework spectral turnover near 100 GeV distinguishes from magnetar) ; CCLXX-P3 population test on the 5 non-detection SLSNe in the Acero+ sample correlated with M (56Ni) reservoir below an fbulk-saturation threshold ~0. 5-1. 0 Mₛun. The framework is not falsified by Acero+. The magnetar interpretation requires ad hoc nebular-magnetization tuning of comparable strength to CCLVII's honest-scope admissions; no clean winner.
