Review context
These calculated indicators are prompts for checking source data, reporting grain, denominators, and local context. They are not evidence or findings of fraud, misconduct, or an incorrect election outcome.
Vote-share correlation crossed threshold: Trump r=-0.252, Harris r=0.761.
Bigger local reporting-unit vote totals move with candidate vote share strongly enough to pass the native review threshold. This is an advisory review flag, not proof of tampering.
