The idea

Keep what the source says separate from what you conclude. ‘Morgan says the notice arrived late’ reports an account. ‘The notice arrived late’ treats that account as a fact. The second claim needs more support.

What to check

A quote can be checked word for word. An inference can also be tested, but it needs a different check: identify its starting facts and ask whether they justify the conclusion. Other explanations may fit those facts.

Use separate fields for source words, a fair summary, and your proposed inference. Mark gaps and conflicts. A model's label is only a starting point; review the reasoning yourself.
