We identify and characterize compact dwarf starburst (CDS) galaxies in theRESOLVE survey, a volume-limited census of galaxies in the local universe, toprobe whether this population contains any residual ``blue nuggets,'' a classof intensely star-forming compact galaxies first identified at high redshift$z$. Our 50 low-$z$ CDS galaxies are defined by dwarf masses (stellar mass $M_*< 10^{9.5}$ M$_{\odot}$), compact bulged-disk or spheroid-dominatedmorphologies (using a quantitative criterion, $\mu_\Delta > 8.6$), and specificstar formation rates above the defining threshold for high-$z$ blue nuggets($\log$ SSFR [Gyr$^{-1}] > -0.5$). Across redshifts, blue nuggets exhibit threedefining properties: compactness relative to contemporaneous galaxies, abundantcold gas, and formation via compaction in mergers or colliding streams. Thosewith halo mass below $M_{\rm halo} \sim 10^{11.5}$ M$_{\odot}$ may in theoryevade permanent quenching and cyclically refuel until the present day. Selectedonly for compactness and starburst activity, our CDS galaxies generally have$M_{\rm halo} \lesssim 10^{11.5}$ M$_{\odot}$ and gas-to-stellar mass ratio$\gtrsim$1. Moreover, analysis of archival DECaLS photometry and new 3Dspectroscopic observations for CDS galaxies reveals a high rate of photometricand kinematic disturbances suggestive of dwarf mergers. The SSFRs, surface massdensities, and number counts of CDS galaxies are compatible with theoreticaland observational expectations for redshift evolution in blue nuggets. We arguethat CDS galaxies represent a maximally-starbursting subset of traditionalcompact dwarf classes such as blue compact dwarfs and blue E/S0s. We concludethat CDS galaxies represent a low-$z$ tail of the blue nugget phenomenon formedvia a moderated compaction channel that leaves open the possibility of diskregrowth and evolution into normal disk galaxies.
