# CMMF

> A portable, platform-neutral format for content models and their intent.

For existing projects, respect the manifest version; never silently upgrade. For new projects use current stable unless experimental is explicitly requested. Specifications are normative; tutorials explain them. Numeric specVersion: 1 means original legacy. Skills helpers do not support beta semantics. Model checks do not validate content or prove CMS translations lossless.
