+abstract: >-
+  A comprehensive framework for classifying problem complexity, 
+  mapping learning progression, and selecting appropriate mental 
+  model combinations for systematic problem-solving. Features a 
+  dual-tier system (Problem Complexity Tiers 1-5 and Learning 
+  Progression Tiers 0-4), quantitative wickedness scoring 
+  methodology (5-question, 0-30 points), Base-N selection 
+  framework (Base6 through BASE120), and empirical validation 
+  from BASE120 mental models research (120 models at 9.1/10 quality).
