When 2D Tasks Meet 1D Serialization: On Serialization Friction in Structured Tasks arXiv:2604.27272v2 Announce Type: replace Abstract: In the LLM era, many symbolic and structured problems are presented to models through 1D text serialization. Yet some such problems are natively two-dimensional: their relevant relations, such as row--column correspondence or spatial adjacency, are defined by position in a 2D layout rather than by sequential order. This raises a representational question: does p
