Operational history
Issues & Camp Impact
The walkthrough documents the solved path, but this pass does not preserve all original challenge pages, audio, images, or server state.
The catalogue summarizes the puzzle structure while avoiding claims that the live challenge infrastructure remains complete.
No Kākācon 2021 sticker image is published because the recovered page images have not been paired with explicit reuse rights, attribution, and processing notes.
The record remains source-backed and image-free rather than copying blog or art-page images without complete provenance.
The Kākācon 2021 source trail proves a sticker-backed badge challenge, not an electronic badge.
The entry preserves the printed challenge artifact without inventing PCB hardware, firmware, RF, display, or battery behavior.
