When cross-cutting concerns dominate your hierarchy,
When cross-cutting concerns dominate your hierarchy, reorganize along a different axis rather than forcing items into categories they only partially fit.
Why This Is a Principle
Derives from Schemas as Knowledge Organization Structures (schemas organize by relationships) and Piagetian Equilibration Through Schema Dynamics (accommodation restructures schemas when they fail). This prescribes recognizing when your organizing dimension is wrong (cross-cutting concerns) and changing the axis itself. It's diagnostic (identifies the pattern) and prescriptive (change axis, don't force fit).
