Issue dossier
The hardware reference calls the board REV 2 dated 2025-05-05, while the public refactored firmware and workshop documentation were committed in May-June 2026. The archive itself labels a prebuilt directory as 2025 production, but no reviewed release or hash maps the later source tree to the original 2025 binary or proves a 2026 electronic-badge reissue.
A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.
