Task: recover a flag from a satellite OBC exposing a U-Boot serial console over TCP where all normal boot devices are missing. Solution: enumerate I2C buses, dump AT24 EEPROMs (AES key/IV on bus 0 @ 0x100, encrypted_flag in the redundant env copy at env_offset=0x800 on bus 1), then AES-256-CBC decrypt across buses.
