And, any idea how to use them? 3 pins is perplexing.

Nope.

UPDI used on Atmel micros on Anduril capable flashlights uses a single line for debug and flashing. Much earlier than that, Motorola/Freescale/NXP Coldfire, S12, and some other MCUs used BDM which was also a single wire protocol.

If you want to flash a newer Anduril to this light, look here for hardware and procedures to use those pads.

The programming hardware won't help because the firmware is closed source.

You don't need the original source to program a flashlight. If it's ATTiny based then Anduril has your back.

I agree. If you are able to define the HW specific part of Anduril for this new model you can create a hex file and flash it.
