Issue dossier
A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.
MK4 needs lifecycle treatment because the shipped camp experience, app behavior, and post-event firmware state were not identical.
Evidence
Official badge-store app rules, folder/header requirements, categories, validation, and pull-request workflow.

Internet Archive mirror for the MK4 USB/DFU update page and wipe warning.
