Editorial & Evidence Log
A public record of material changes to evidence ratings, factual corrections, methodology, and substantial research on IntrinsicAge.
What this log records
This is a record of material changes to the science and content on IntrinsicAge — not a log of engineering activity. It includes evidence rating changes, factual corrections, methodology or editorial changes, market and test information, and substantial new research pages. Routine design, SEO, analytics, and maintenance work is not listed here. Changes affecting medical or evidence content are reviewed before publication.
