Operational history

Issues & Camp Impact

Area41 2018 Proteus Badge note

hardware archive gap · source-conservative public archive · needs schematic or BOM recovery

The source set proves ESP8266, WiFi, display, button inputs, and firmware behavior, but not a complete schematic, BOM, PCB revision, display part number, enclosure, or battery specification.

The hardware section intentionally avoids component-level claims beyond public sources until an original hardware archive or transcript is recovered.

ZeTeCo 2017 Badge note

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

No local ZeTeCo 2017 badge image is published because the accessible public sources prove the badge and camp context but no reusable original badge photo, official raster, or transcript-derived still has been recovered with source URL, license or permission basis, attribution, and processing notes.

The record stays source-backed and image-free rather than copying talk thumbnails, wiki media, crowdfunding images, attendee photos, screenshots, placeholders, or generated approximations.

Area41 2018 Proteus Badge note

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

No Area41 2018 badge image is published because the recovered wrap-up and linked social images do not provide the complete reusable license, attribution, source URL, and processing record required by badge.gallery.

The record remains source-backed and image-free rather than copying blog, social-media, or repository imagery without complete provenance.

Area41 2018 Proteus Badge note

scope boundary · source-conservative public archive · documented caveat

The public Proteus archive documents firmware and build/update workflow; it does not by itself clear badge photos or prove every attendee-distribution detail beyond the Compass report's Area41-team badge statement.

The dossier presents the badge as a real Area41 2018 artifact while keeping image rights and distribution-depth claims narrow.

ZeTeCo 2017 Badge note

source-depth caveat · talk page and archived wiki · needs transcript and original media recovery

The badge is source-backed, but detailed component specifications and licensed original photos still need recovery.

The dossier avoids speculative hardware claims and withholds imagery until primary design files, photos, or a transcript are cleared.
