expression-clarify

Make code more expressive so logic and intent are self-evident through naming, structure, flow, and locality. Use when: (1) asked to prepare code for review where implementation requires translation effort to understand, (2) explanations require translating from implementation details to meaning like "this variable represents...", (3) function names describe mechanics rather than purpose or comments explain what code does rather than why, (4) choosing between working implementations based on which will be clearest to future readers.
