Issue dossier
A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.
No safety, battery-life, interoperability, or reliable wireless-operation claim is inferred from the visible board documentation.
Evidence
Public README for the ESP32-C3 badge feature surface, source layout, source-based workshop context, hardware-reference link, and 2025-production binary directory boundary.
Public hardware reference for the 100 mm board, documented components, power paths, and stated REV 2 production date of 2025-05-05. It is not treated as an independently audited production or safety report.
Organizer page explicitly headed `2025 BSIDES BADGE PROGRAMMING`; calls the artifact the 2025 electronic badge, links the first-party programming bundle, and directs firmware information to the public source archive.
Official archived speaker schedule placing the main conference programme on May 26, 2025; used for event context alongside the separate badge archive.
Official archived schedule placing workshops on May 25, 2025; used only for dated event context, not hardware or recipient-allocation claims.
BSides Vancouver's own GitHub organization describes this repository as files for programming the 2025 Electronic Badge and preserves the bootloader, partition table, badge binary, and helper script.
Public project archive linked directly by the organizer's 2025 badge page. It describes the ESP32-C3/NFC badge and workshop material but is separate from the organizer's first-party binary-only bundle.
Public changelog that calls v2.4.0 the first public refactored firmware release and describes later source behavior without proving the factory 2025 image.
MIT license naming Copyright 2025-2026 BSides Vancouver Society for the source archive's software and associated documentation; it is not assumed to clear every image, logo, board-art, or event-media asset.
GitHub history dates the initial public v2.4.0 firmware/workshop documentation release to May 29, 2026 and related updates to May 29-June 1, 2026; this timing is kept separate from the 2025 production badge.
Source trail
Primary first-party repository description and file listing for the 2025 Electronic Badge programming bundle.
Primary license source for software and associated documentation in the public archive, with separate visual-asset scope retained.
Primary organizer source identifying the 2025 electronic badge and linking both its programming bundle and public firmware information.
Primary archived event source for the May 26 conference schedule context.
Primary archived event source for the May 25 workshop-day context.
Primary public source for the ESP32-C3, NFC, sensor, LED, Wi-Fi portal, mini-CTF, source-layout, and workshop-context statements.
Primary public hardware documentation for component declarations, power outline, physical dimensions, and the stated 2025-05-05 REV 2 production board.
Primary source-publication chronology: initial public release and workshop documentation appear in late May 2026, not during the 2025 event.
Primary public changelog distinguishing the later v2.4.0 source release from an identified 2025 production binary.
Public source archive linked by the organizer's 2025 badge page; supports technical source and workshop claims while remaining distinct from the first-party binary bundle.
