First radio observations of SN 2023fyq detect a dense circumstellar shell with mass-loss rate ~0.004 solar masses per year ejected 0.7-3 years before explosion, consistent with a merger origin.

GRB 210704A at z=2.34 shows a luminous fast blue transient excess peaking at ~7 days, modeled as refreshed shock emission and linked to LFBOTs alongside a high-Lorentz-factor jet.
High luminosities above 10^44 erg/s and compact radii below 10^14 cm suppress H and He lines via high ionization and temperature, with non-homologous compact outflows needed for persistent featurelessness in LFBOTs and TDEs.
