Claim: GRADE's core insight is that evidence quality and recommendation strength are independent axes. Four certainty levels, five downgrade criteria, three upgrade criteria.
BLUF: All four sub-claims confirmed. GRADE explicitly separates evidence
quality from recommendation strength, defines four certainty levels, five
downgrade criteria, and three upgrade criteria. The "core insight"
characterization is editorially reasonable.
Probability: Almost certain (95-99%) | Confidence: High
