The term for universal concomitance in Indian Logic is:

Universal concomitance names the invariable, pervasive relation between the reason and the probandum, as of smoke with fire.

It states that wherever the reason is present the probandum is present too, without exception.

This pervasion is the very ground that makes inference possible.

Hetu is the reason, sadhya the probandum, and drishtanta the example, but none names the pervasion itself.

The technical term for such invariable concomitance is vyapti.
