Research direction

No repository file or test is identified. Start by reproducing the reported tensor.scatter_add_ case with the provided indexing expression, ONNX conversion, and TensorRT 8.6.1.6, then compare the TensorRT output with the source model. Done means the discrepancy is isolated and either fixed or documented with a minimal reproducer.
