Evidence Registry
Every claim we make is catalogued, graded, and linked to its source. No hand-waving, no "studies show" without the study.
The registry structure
Each evidence entry includes: the claim, BOX tier grade, primary source, publication year, and verification status. We update the registry quarterly as new research emerges.
