Issues & Camp Impact

BugCON 2022 Badge note

firmware-source caveat · repository tree and decoded sketches · needs deeper firmware inventory

The firmware tree preserves Blink_Bug, AudioWAV, Chona.wav, and an EdgeImpulse note, but this pass did not audit every sketch dependency, runtime command implementation, challenge binary, audio asset provenance, or final shipped firmware image.

Software claims stay tied to the README instructions, visible firmware tree, and decoded example sketches rather than treating the repository as a complete final production firmware archive.

BugCON 2022 Badge note

license-file caveat · GitHub API and repository README · documented with caution

The README says hardware is released under CERN Open Hardware Licence v1.2 and says to consult a LICENSE_HARDWARE file, but this pass found no top-level `LICENSE_HARDWARE.md` through the GitHub contents API and GitHub reports no detected repository license.

The catalogue can cite the README's open-hardware claim and public source while avoiding assumptions that firmware, photos, readme images, logos, KiCad renders, or other repository media are reusable publication assets.

BugCON 2022 Badge note

missing rights-cleared image · local project policy · needs licensed original replacement

No BugCON 2022 badge image is published because the README logo, repository media, site graphics, screenshots, and hardware-source render candidates have not been paired with complete reusable image rights, attribution, source URL, and processing provenance for catalogue publication.

The entry remains source-backed and image-free rather than copying event logos, README images, GitHub assets, KiCad screenshots, social photos, or generated imagery without complete provenance.
