Expand concept fan from purpose through concepts to ideas.
Subagent — spawned via subagent-spawning/spawn-agent skill.
Concept fan expansion requires maintaining multiple abstraction levels simultaneously and generating ideas at each level. Benefits from dedicated context that can hold the full fan structure while exploring each branch.
Perform bisociation at multiple abstraction levels
Complete blend with background knowledge
Compose new connections in blended space
Construct complete 4-space blends with emergent structure. Orchestrates input-space-construction → generic-space-extraction → blend-composition.
Run blend as mental simulation
Combinatorial Creativity Campaign — produce emergent concepts via concept blending, multi-level bisociation, and function combination (Fauconnier-Turner)
