High-contrast imaging of 18 compact-object binaries yields no robust tertiary detections and rules out main-sequence tertiaries at projected separations greater than 500 au for Gaia systems and 2000 au for BH LMXBs.

Hierarchical Bayesian inference allows accurate recovery of intrinsic astrophysical source populations even when follow-up selection is unknown and correlated with parameters of interest.
Stellar evolution and atmosphere models predict black hole progenitors are predominantly hot and blue with a direct-collapse rate of ~0.4 per century in a 1 Msun/yr star-forming galaxy.
Natal kicks from supernovae are proposed to disrupt Gaia progenitor binaries containing low-mass black holes more frequently than those leading to gravitational-wave mergers, accounting for the observed difference in the 2.5-5 solar mass gap.
SED fitting plus kinematic diagnostics identify 182 top dormant BH/NS binary candidates from Gaia DR3, with 19 likely black hole systems having companion masses >=3 solar masses.
