First definitive X-ray shock breakout from a Type Ic-BL supernova, with radio constraints and a rate calculation implying most such supernovae produce fainter signals than observed here.
Multi-shell modeling shows outward 56Ni mixing produces faster brighter rises and biases one-zone fits to lower ejecta mass and higher nickel fraction, while r-process signatures in collapsars depend on placement, distribution, and viewing angle rather than always showing NIR excess.
Multi-wavelength monitoring of nearby SNe Ic-BL adds new constraints on the fraction with relativistic jets comparable to SN 1998bw and flags candidates for choked jets and CSM-driven radio emission.
EP260321a is identified as the faintest shock breakout X-ray transient associated with broad-lined Ic supernova SN 2026gzf, interpreted as originating from a mildly relativistic weak outflow choked inside the progenitor star.
