Don't make Gemini judge your AdMob report — confine structured output to extraction
When deciding AdMob floors (eCPM thresholds), letting Gemini make the decision itself is dangerous. Confine structured output to 'extracting a messy report into typed data,' and keep the threshold judgment in deterministic code — here is the reasoning and implementation, with the actual decision rules from running 42 groups.
