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.
Samuel's three-days-of-darkness death-sign, fulfilled. Shared duration 'for the space of three days'; the darkness/no-light contact ('no light seen' <-> 'darkness should cover'). The people watch for this sign by name: 'the people began to look with great earnestness for the sign which had been given by the prophet Samuel, the Lamanite, yea, for the time that there should be darkness for the space of three days over the face of the land' (3 Nephi 8:3). Samuel's Helaman 14 leg (also 14:20 'no light upon the face of this land … for the space of three days'); Zenos's vapor-of-darkness leg (1 Nephi 19:11) hosted on zenos.md.
