Edward de Bono's Concept Fan — climb from the current solution to the concept it serves by asking "what is this a way of doing?", then fan out alternative concepts and concrete implementations for each. Use when the current solution might be answering the wrong question, when all options look like variations of one idea, or to widen a decision before committing. Triggers include "concept fan", "zoom out", "what is this a way of doing", "wrong problem", "widen the options", "abstraction ladder". Do NOT use for analytical work like debugging, code review, or implementation tasks.

Implement work from an approved spec or ticket set, run focused and full tests, invoke code review, and commit the result to the current branch.
