Opportunity Matrix — "CAD Lore"

The space of AI-HWE workflow combinations — LLM model × CAD host × plugin/bridge — scored to show which coordinates are proven powerful and which are empty plugin vacancies worth building. High score = proven combo. High potential but empty (dashed) = the build backlog.

score = capability 0.4 · autonomy 0.25 · openness 0.2 · ease 0.15
