East-West · M4 flagship

One signed measurement, every regime it touches, mapped.

Cross-jurisdiction governance measurement without selling scores. Regulators read the crosswalk free forever; determination stays with authorities. Verify any regime's evidence without asking us.

Determination stays with authorities. This surface maps obligations and publishes signed measurements. It is not a conformity mark, certificate, or legal opinion.
