Recognize that choosing a primary hierarchy is a priority
Recognize that choosing a primary hierarchy is a priority decision that reveals what you are optimizing for by making certain retrievals easy and others difficult.
Why This Is a Principle
Derives from Goals as Perceptual Filters (goals determine relevance) and Abstraction Necessarily Discards Information (abstraction discards information). This reframes hierarchy choice as a values question: your structure prioritizes certain access patterns over others. It's diagnostic (reveals implicit priorities) and sets up the bridge to L-0276 on priorities. Highly general and conceptually powerful.
