Find market gaps by chaining demand evidence with a supply audit — verify people want something, then grade how well existing tools serve it, and classify each pocket UNSERVED / UNDERSERVED / WELL-SERVED with cited evidence. Trigger with /gap-scan <seed space or demand pocket>, or when the user asks "is there a gap in X", "what's missing in the X market", "who already does this and are they good", or wants demand+supply evidence before committing to an idea.
