Issue dossier
The official event page documents the Underground badge's ESP32, screen, controls, badge-to-badge communication, SAO support, and CTF framing, and a maker writeup documents a WS2812B SAO board, but this pass did not recover public firmware, schematic, PCB, BOM, radio protocol, or production files for the main badge.
A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.
