Attribution Gap

No public individual author, designer, firmware, or team credits have been seeded for this badge yet. Add named credits only when a primary badge-team page, repository, talk, or other source identifies the people or team behind the work.

Why It Mattered

It pushes the source-backed DEF CON credential lineage back into 1994 while keeping the evidence boundary explicit: the public source trail proves printed conference identity credentials, not electronics, firmware, or a hackable badge platform.

Hardware

The official DEF CON 2 media-server unsorted photo set shows rectangular printed chest credentials, including magenta-and-white cards visible on speakers in the KM-1 and KM-2 images. No electronics, power source, microcontroller, display, RF, firmware, or badge-hacking hardware is claimed.

Software & Apps

No software or firmware is claimed. This record treats the DEF CON 2 badge as a physical admission/identity artifact from the pre-electronic DEF CON era.

Lore

The official archive page preserves DEF CON II's 1994 Sahara context, announcement, picture archive, program trail, audio, and post-event article links. The official archive photos are used only as evidence for visible credentials because DEF CON's embedded copyright metadata and media-server copyright context do not satisfy this site's image-publication policy.

Issues & Camp Impact

missing rights-cleared image note

No local DEF CON 2 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.

non-electronic scope note

DEF CON 2 is modeled as a non-electronic physical chest 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.

source-depth caveat note

The current public sources prove visible DEF CON 2 rectangular printed chest 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.
