Lifecycle
The official badge page says AvengerCon IX's badge carried a small four-challenge CTF contest.
After AC9, the official badge page published four booth/village unlock codes for people who missed them during the event.
The badge page documents BAT CON jumper behavior and warns users not to keep the coin cell connected while the badge is plugged into a computer.
The badge page documents CP2102 USB-to-UART access, /dev/ttyUSB0 discovery, PuTTY, and 9600-baud serial connection guidance.
Operational history
The catalogue keeps the strong official badge-guide evidence while avoiding unsupported claims about the unrecovered design files or shipped firmware internals.
The entry remains source-backed and image-free rather than copying the official page image, Army event photos, screenshots, social media, or generated visuals.
