Active Skillference: A Validated Prerequisite Graph, Computational Claim Registry, and SkillTree Delivery Contract

Active Inference and the Free Energy Principle (FEP) provide model-based accounts of belief updating, learning, and action under uncertainty. We present Active Skillference, a provenance-bound curriculum-generation and SkillTree-export system for teaching those formal ideas. The paper evaluates structural validity, quantitative provenance, citation-role coverage, and artifact reproducibility; it does not evaluate learner outcomes, establish a new theory of Active Inference, or present an intelligent tutoring system. The curriculum is expressed as code: a typed, validated directed acyclic graph of 630 skills across 111 subjects spanning all 8 strata (mathematics - probability - information theory - variational methods - the FEP - active inference - computation - applications), connected by 1199 prerequisite edges with a maximum dependency depth of 75 (of which the substantive concept chai
