Issue dossier
A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.
Source code can be linked as evidence, but no repository media or event imagery is copied into the public catalogue and the badge remains image-free.
Evidence
Contemporaneous attendee report corroborating the hardware-hacking context and crediting Carl Vargklint's badge work; it does not establish universal attendee allocation or assembly.
Public repository pinout reference for the badge's labelled RP2040 interfaces; it does not replace a schematic, PCB release, or BOM.
Security Fest's official completed-event page establishes the May 28-29, 2026 conference at Elite Park Avenue Hotel in Gothenburg.
Public repository identifying itself as the official firmware repository for the Security Fest 2026 conference badge; it is source evidence, not a formal hardware-production release.
GitHub profile identifying the repository publisher Superminaren as Carl Vargklint.
GitHub REST metadata records the May 2026 repository creation/push window and no formal repository license classification.
Repository README documenting the RP2040, memory, LED matrix, front LEDs, buttons, USB, SAO, GPIO, and high-level firmware surfaces.
Source trail
Publisher identity source showing the Superminaren GitHub profile name as Carl Vargklint.
Repository metadata observed in this audit records a May 2026 creation/push window and `license: null`; the README's informal reuse language is not treated as a formal catalogue image license.
Contemporaneous attendee corroboration for hardware-hacking interest around the badge and a narrow credit to Carl Vargklint; it does not prove issuance, manufacturing, or every attendee's experience.
Primary event source confirming Security Fest's ninth conference at Elite Park Avenue Hotel on May 28-29, 2026 in Gothenburg.
Primary badge source calling itself the official firmware repository and documenting the device's concrete hardware and high-level firmware surfaces.
Primary public source-tree record for the badge firmware, repository structure, and its conference-badge association.
