This graph links five evidence clusters: implicated products and lots, firms in the supply chain, state case counts, regulatory and agency actions, and MDL No. 3196 litigation. Edges are marked Verified (documented in a primary source), Inferred (analytical judgment), or Gap (an unresolved, disputed, or not-yet-established link). The known gaps are enumerated under the Open Questions button and include: the outbreak-wide attribution remaining open, the unlinked North Carolina second vehicle, Mexico's government-level dispute of the attribution backed by a negative environmental test, the absence of any confirmed positive product sample after the import-surveillance retraction, two FDA outbreaks with products not yet identified, and the JPML not having ruled on transfer.
