Off-axis cocoon emission from long GRB jets produces fast X-ray transients with luminosities of 10^47-48 erg/s, durations of 10-100 s, and soft quasi-thermal spectra peaking near 0.8 keV.
The paper identifies supernova emission matching a scaled SN 1998bw template in the late-time light curve of EP250302a at z=1.131, with early data constraining the jet Lorentz factor above 25.
