Issue dossier
A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.
The record remains source-backed and image-free rather than copying DEF CON archive photography without complete rights clearance.
Evidence
VICE/Motherboard history placing the first DEF CON electronic badge at DEF CON 14 in 2006, supporting DEF CON 4's conservative non-electronic classification.
InfoconDB source for the July 26-28, 1996 DEF CON 4 dates, Monte Carlo Resort and Casino venue, official page link, and program/archive references.

Official media-server directory for DEF CON 4 pictures, including Evil Pete, Lockheed, MCS, Pluvis, TDYC, and Wyatt event-photo sets.
