Abstract: What are the explosion mechanisms and progenitor star systems of supernovae? In the early hours to days after explosion, supernovae provide clues to how they explode, and what their progenitor star systems were.  We will discuss specific examples of ephemeral, but critical, signatures in early supernova data (e.g. early light curve ‘bumps’, flash spectroscopy, shock breakout cooling) and what they are teaching us about these cosmic explosions, with an eye towards what even deeper/fainter observations might provide.  Beyond the current landscape, we will discuss the science that will open up by `shadowing’ the Legacy Survey of Space and Time (LSST) with either Blanco+DECam or another moderate aperture telescope in the hours or day after the Wide, Fast, Deep survey has observed a nearby galaxy structure.  Opportunities that were possible only once or twice per year will increase by an order of magnitude, and will benefit from direct ties between discovery and follow-up facilities.
