Variants & notes — as the dossier prints them
- VERSIONS DISPUTE — kept as a dispute card by the adjudication: the revised (evidence-based) set leads; the classic set prints beside it as the traditional form. The two are never blended.
- Exam variant (footnote): Medbullets prints "wind, water/womb, walking, wound, weird/wonder drugs" with different timing.
- UNRESOLVED (register D-37): the Tamer-supplied list's extensions (Widgets; Wabscess; Wing/Waterway) remain Tamer-list-only — recorded here as an open question, not printed as versions.
