you win! openFPGALoader -b arty demo35.bin --write-flash that simple and my arty is just like one fresh out of the box. Thank you. This doc implies maybe the source is available in the wild, but I spent much time trying to find it or find someone who could help no luck. https://www.avnet.com/opasdata/d120001/medias/docus/178/UG-AES-A7MB-7A35T-G_Arty_OOB_GPIO_demo_V1.pdf but that's OK, I don't need the source, just the bin file you supplied, so thanks again.

BTN1: 'Cylon' LED display. BTN2: Scrolling LED display. BTN3: Return to this menu. and blinks the LEDs per button presses. The purpose is for students in a lab to start with a 'fresh' board like when it comes out of the box.
