  Eradicating Syntax: Building a Neural Universal Machine That Executes Graphs, Not Code

  Our GNN autoencoders achieved 81% node accuracy on Ruby ASTs yet produced 0% valid code. The culprit was the literal value bottleneck — nearly half of every AST consisted of...

  The Literal Value Bottleneck: Why GNN Autoencoders Fail at Code Generation

  We trained GNN autoencoders on 22,000 Ruby ASTs. The models achieved 81% node type accuracy and 99.5% type diversity, yet generated exactly 0% syntactically valid code. Here is why.
