CORE MASTERY

Dead / Cancelled — Cancelled — Section 8 (as of 20 Mar 2026)

What this means for you

This registration has been cancelled; it no longer blocks anyone on its own. The name may be available, but check before relying on it — rights can also come from actual use, not only from the register.
