This profile traverses clone_of · derived_from · design_imitation_of · ebauche_of · incorporates_module · licensed_copy_of · module_on · revision_of · tooling_transfer_of · variant_of and keeps disputed edges. Every edge in this view carries at least one reference.
Generations run left to right, ancestors first, and the axis along the top is ordinal rather than linear: each band is one generation, labelled with the range of sourced introduction years it contains. A band reads “—” when no caliber in it has a year anyone published — the gap is the finding, not a rendering failure. Dotted arcs above and below the drawing are related edges — successor, drop-in, no-derivation — which are stored in a different table from lineage and can never form part of an ancestry path.
