Issue dossier
No 39C3 Critical Decentralization Cluster Badge image is published because the current public source trail has not been paired with a reusable original badge or artifact photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.
A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.

assembly retrospective
The cluster's own 39C3 page ties the CDC Badge repository to the completed December 27-30, 2025 Hamburg assembly context.
Badge: 39C3 Critical Decentralization Cluster Badge
firmware status and safety documentation
The firmware README documents ESP-IDF/PlatformIO, FIDO2/WebAuthn, GPG/SSH, TOTP, password-vault, plugin, BLE, and data-loss/early-beta caveats.
Badge: 39C3 Critical Decentralization Cluster Badge
hardware and documentation repository
RIAT's public CDC Badge source tree with KiCad hardware, printable cases, documentation, fabrication instructions, expansion descriptions, and linked firmware projects.
Badge: 39C3 Critical Decentralization Cluster Badge
hardware license
Public CERN Open Hardware Licence v2 Permissive source for the RIAT CDC Badge project, with third-party component attribution retained separately by the repository.
Badge: 39C3 Critical Decentralization Cluster Badge
official 39C3 assembly event
Primary official Congress event page explicitly calling the artifact an electronic conference badge and devboard, and naming its TROPIC01, ESP32-S3, e-paper, LiPo, keypad, and expansion surface.
Badge: 39C3 Critical Decentralization Cluster Badge
official assembly page
Official 39C3 assembly page for the Critical Decentralization Cluster, which lists the CDC Badge presentation in its recorded assembly programme.
Badge: 39C3 Critical Decentralization Cluster Badge
post-event public firmware
Public GPL-3.0 firmware project for CDC Badge v1.0/v1.1 hardware. Its January-July 2026 public history is kept separate from an asserted 39C3 deployed image.
Badge: 39C3 Critical Decentralization Cluster Badge
power and firmware caution
Source-published checklist covering BQ25895 charge-current/power settings, USB interaction, and TROPIC01 sleep requirements; it is not proof of configuration on every event unit.
Badge: 39C3 Critical Decentralization Cluster Badge
versioned open-hardware release
Public v1.1 release evidence for the CDC Badge hardware tree. It does not identify which source revision, if any, was on a particular 39C3 physical unit.
