Issue dossier
No THOTCON 0xD Badge image is published because the current public source trail has not been paired with a reusable original badge or artifact photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.
A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.
