mmm-attribution-reconciler
Cross-reference MMM channel ROI against platform-reported ROAS (Google Ads, Meta Ads Manager, etc.) and surface where they agree vs. disagree — and which disagreements demand an incrementality test. Use when the user mentions "platform vs MMM", "why does Google Ads say X but MMM says Y", "ROAS doesn't match", "reconcile attribution", "platform ROAS vs MMM", "which number to trust", "attribution gap", or "MMM disagrees with the platform".
