Issue dossier
The repository review confirms schematics, Gerbers, LCSC parts exports, media, 3D-print files, NE556-related challenge material, and multi-board RCA structure, but this pass still does not claim a complete firmware architecture or full electrical BOM extraction.
A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.
