Design containers to provide interpretive context that items

Why This Is a Principle

This derives from Schemas as Knowledge Organization Structures (schemas organize knowledge by specifying relationships), Hierarchical Chunking Expands Capacity (chunking allows treating groups as single units), and Abstraction Necessarily Discards Information (abstraction discards information). The principle prescribes HOW to design containers: they should add meaning through context rather than requiring every item to be self-describing. It's actionable (tells you what containers should do), general (applies across knowledge systems), and derived rather than foundational.
