High-resolution simulations demonstrate that two-zone models for GRB early afterglows fail to match hydrodynamic evolution in the Newtonian reverse shock regime before Blandford-McKee self-similarity, causing systematic overpredictions of emission depending on the transition prescription.

PIC-motivated acceleration models for GRB afterglows predict a GeV-band synchrotron cutoff in low-density short GRBs that current Fermi-LAT data cannot distinguish from the Bohm limit but future observations could.
