- Question“What is the notice period?”
- RetrieveSearch the indexed documents; pull the best-matching passages.
- GenerateThe model answers from the question plus those passages.
- CiteEach statement points to the passage it came from.
Two things can still go wrong: the search misses the clause that matters, or the model misreads the clause it was given. The citation lets you check which happened.
A concrete example
A user asks for a summary of a line of authority and receives linked citations to the publisher's collection.
The distinction that matters
A linked citation shows where the system looked. It does not show that the authority says what the summary claims.
