Field notes

The walkthrough names an STM32 NUCLEO-F401RE and shows the project being built, flashed, and tested on the board. The page says its demo reached a VERIFIED verdict in 31 seconds after eight checks, and offers an HTML report export. It also reports a benchmark in which Unfix accepted four of ten fixes from an AI agent; that result is presented as the site's own claim.
