That allowlist fixes invented documents but does nothing for the dental case, because the source that got inverted was real and on the list. I don't trust a check that leans on a single line to catch an inverted answer. Ten sampled answers a week against a policy that had been wrong 4,000 times reads more like a hope than a control. The 0.85 quote span check is closer to the mark, since an inverted answer drags a span with it that doesn't say what the answer claims.
