Operational history
Issues & Camp Impact
The organizer-owned archive and organizer updates prove a real 2026 Harp Badge, but the recovered public sources do not name the badge designer or give a production/distribution quantity.
The dossier does not infer designer credit, attendee allocation, or production scale from the technical archive alone.
No BSides Dublin 2026 Harp Badge image is published because the public archive and organizer updates do not pair a specific physical badge image or official raster with a reusable license or permission basis, attribution, source URL, and processing record.
The dossier remains source-backed and image-free rather than copying repository PDF media, event graphics, or organizer social imagery without complete provenance.
GitHub's repository metadata reports `license: null` for the public organizer-owned HardwareBadge2026 repository. Third-party dependency licenses within its vendored firmware tree do not establish a license for the organizer's badge source, manufacturing files, guide, or media.
The archive remains a valuable technical source, but it is not treated as permission to republish badge imagery or assume a universal source-license grant.
