Issues & Camp Impact
No local DEF CON 3 badge photo has been added because the official media-server event photos do not provide a complete reusable license, attribution, and processing-provenance trail for this catalogue.
The record remains source-backed and image-free rather than copying DEF CON archive photography without complete rights clearance.
DEF CON 3 is modeled as a non-electronic physical waist credential because the public source trail proves identity/access artifacts but does not support electronics, firmware, or hackable hardware claims.
The compendium preserves the early conference credential without upgrading it into a circuit-board badge.
The current public sources prove visible DEF CON 3 colored rectangular waist credentials but do not identify the badge designer, production process, material, full role taxonomy, or any official puzzle layer.
The record limits claims to visible physical-credential evidence and event context.
