“The vector table is at the top,” Elara whispered in his ear. “But the Watchdog has fortified it. You’ll need a key.” Firmware Mtech 8803

“You’re a failsafe,” Leo shouted, holding the NOP sled like a lance. “Not a king. You reset the wrong fault. The MT8803’s watchdog was supposed to trigger only on hardware hangs. But you’ve been resetting on software interrupts —you’re the reason the firmware keeps corrupting!” “But the Watchdog has fortified it

“You bricked it,” said a voice. It came from everywhere and nowhere. “Three weeks of overtime, and you pushed a corrupted bootloader. Congratulations. You killed the prototype.”

“A NOP sled. A long slide of no-operation instructions. It’s the only thing the firmware can’t interpret as a threat.”

“No,” he said, smiling weakly. “I just fixed a bug. That’s what we do.”
