SCOPE OF THE LICENSE

This license applies to the textual material of the Coaching Trust
Framework: the normative document, the system prompts and knowledge
bases of the helper agents, the certification schemes, the validation
methodology and templates, the explainers, the RFC templates, and any
other text produced as part of this repository.

This license does NOT propagate to platforms or products that merely
implement CTF in their own systems. A platform that uses the CTF
toolkit to design, test, audit and operate its own AI coaching agents
is not required to publish or open-source those agents under any
license. The ShareAlike clause only applies to republications or
derivative works of the CTF text itself.

Federation declinations (CTF-ICF, CTF-EMCC, etc.) are derivative works
of the CTF text and must therefore be released under CC BY-SA 4.0 (or a
compatible license that preserves the same level of openness).
