Splits the answer into sentences and measures, for each one, how much of it is covered by the supplied sources. Coverage is asymmetric on purpose: the question is what share of the statement appears in the source, so a long source can fully cover a short claim, and it combines single-word overlap with word-pair overlap because the same words in a different order can mean something else.

Knocking goes to the knock page, which reads the terms live before anything is signed. A listing can be out of date in both directions, which is the reason to knock rather than to read a row.
