comment Linux - Is there a way to determine what mac addresses an interface has seen traffic from?
Like I stated in the question arp will not work; it's a glue between IP and Ethernet and thus requires that the IP address is recognized as valid in order to set up the glue. If an interface sees broadcast traffic sourced outside of configured networks on the interface it's not going to bother trying to set up the arp table entries for it.

Yeah, unfortunately packet capturing for a period of time and filtering the results isn't an option for this case. I'm looking for something more at the driver level that logs seen traffic and not something that needs to be done interactively.

Actually, that might be doable. Always forget about good 'ol .bat.

Unless that host isn't Windows.

Somewhat. I've edited in my reservations about netcat.
