Can I Create a Derivative of the PESO Model®? (No—What “Derivative” Means)

TL;DR: No. Derivatives are not allowed.

What “derivative” means: Any modified or expanded version of PESO®: renamed models, additional stages, “PESO® and,” new acronyms, custom frameworks built on PESO, or any version that changes the model or implies ownership.

Why this rule exists: Derivatives create confusion, dilute the model, and result in inconsistent teaching and implementation.
