Compound Finding
A cross-category diagnostic finding that fires when two or more single-category findings correlate, revealing the root cause rather than just listing symptoms.
Why it matters
Knock + high IAT might both appear as separate findings, but the compound rule "heat-induced knock" tells you the root cause is cooling, not timing. This changes what you should fix.
What to look for
Compound findings appear in the "Cross-Category Insights" section. They override individual findings with more specific, root-cause-based advice.
