Why Drug Toxicity Can’t Be Predicted in Isolation — Building EIRION with Graph Neural Networks

How we built a graph neural network that finally sees the whole play - not just the audition Every year, drugs that passed early safety tests go on to harm people in ways nobody predicted. Not because the chemistry was wrong. Not because the researchers were careless. But because we kept evaluating drugs the way a talent agent judges an actor from a solo audition tape. Isolated. Out of context. No script. No co-stars. No stage. In real theatre, a performance is never just about one actor.
