Detailed Description

Index tables for the upward (collect) message of one non-root clique u to its parent.

The message is formed over a product space: the states of clique u, combined with the separators to its children. For each product state the tables give the flat index of the matching entry in every input and in the output, so the message is a gather, a multiply per child, and a scatter add. All indices address state configurations without the batch dimension; batched buffers are read at index * batch_size + row.
