Mosiah 3:17 · 2 Nephi 31:21
This connection's citations are checked against the source text.
The mark sits beside every quote a connection carries. It reports one thing: those words were found in the frozen source text at the reference this page cites, allowing only typographic differences such as curly quotes, dash forms and spacing.
It is not a tier signal, and it is not a judgment about the connection. Where a card carries the Interpretive badge, the reading is still offered with its evidence for you to weigh — the mark speaks only to the citations.
The badges and the mark are separate signals: Textual and Interpretive name the kind of claim a connection makes, while the mark reports that the connection's citations were checked.
The double way+name exclusivity sentence occurs at exactly these two places (Nephi orders way-then-name; the angel name-then-way). Distribution: name-only form at 2 Nephi 25:20 ('none other name given under heaven… whereby man can be saved') and Mosiah 5:8 ('no other name given whereby salvation cometh'); means/conditions side alone at Mosiah 4:8.
