Four buckets
We separate: (1) merchant claims, (2) direct measurements, (3) user reports, and (4) independent scientific or regulatory conclusions. A statement can be accurate in one bucket without proving another.
Current-data checks
Prices, promotions, model names, return policies and warranties change. We cite live merchant sources where practical and encourage readers to verify the checkout-era terms.
Health-adjacent claims
We use conservative language and public-health context. We do not convert laboratory proxies or testimonials into disease-treatment claims.
Corrections
When a material factual error is identified, the page should be corrected and its review date updated.
