Issue dossier
A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.
The record treats the score and synchronization system as documented event-time behavior, not a permanently available badge service.
Evidence
Public DEF CON Singapore talk record naming DC-SG-1 as the electronic badge issued to ticket holders and describing its hardware-hacking, application, and interaction context.
MIT-licensed public infrared compatibility reference that explicitly lists official DEF CON Singapore 1 conference-badge support; it is a protocol reference, not a DCSG1 firmware or hardware release.
Official DEF CON page anchoring the April 28-30, 2026 Singapore conference at Marina Bay Sands, the host event for the official DC-SG-1 attendee badge.
Archived official-badge guide for the infrared Laser* Tag game, local hit records, five teams, ESP-NOW base-station synchronization, DCSG1 ESP32-C6 attribution, Circuit Crafters board credit, and Dani Weidman game credit.
