Observational evidence links obscured super-Eddington accretion to slower precessing jets in stellar-mass compact object systems, contrasting with fixed fast jets in low-density environments.
Radio precedes X-ray Compton luminosity by ~3 days in the rising hard state but lags by ~8 days in the decaying hard state of GX 339-4, with inner magnetic field strength estimated from accretion rate and truncation radius accounting for both.
SKA+VLBI will deliver microarcsecond astrometry, polarimetry, and rapid multi-frequency imaging to track jets and accretion in X-ray binaries on AU scales.
