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 phrase 'isles of the sea' occurs at eight verses (1 Nephi 19:10, 19:12, 19:16, 21:8, 22:4; 2 Nephi 10:8, 10:21, 29:7), and the inhabit-assertion is not phrased at 1 Nephi 22:4 ('scattered to and fro upon the isles') while it IS verbatim at 1 Nephi 19:10 ('those who should inhabit the isles of the sea'). Nothing distinctive ties 10:21 to 22:4 specifically; it is a thematic link.
