This archive contains the reproducibility package for the manuscript “Structural Geometry of Layerwise Representations in Transformer-based Language Models”.It includes the extraction script, structural post-hoc analysis script, figure-generation script, processed structural-index tables, metadata, and final figure files. Raw hidden-state tensors are not included due to storage size and model-license considerations, but they can be regenerated from the public models and datasets using the provided extraction script.
