I think you'd need the compliance voltage-limited to say 0.2V to not damage anything. That pretty much rules out the LM317, have to use an op-amp and power transistor.
I also do well with a good bench multimeter reading uV, using lower currents. You inject a current and can follow the voltage drop to the high current short. Or use a thermal imaging camera.
