Your GNN is probably just an overcomplicated MLP (Tabular Leakage). We built SynthFin-AML to enforce strict causal boundaries. [P]

We noticed our anti-money laundering models were performing suspiciously well. After digging into standard baselines on dynamic graphs, we found widespread temporal leakage in message-passing. If you train a GNN on a static snapshot of a dynamic graph, your model is likely cheating by seeing future
