 > - Files in `expression_matrix/*.npy` are **sharded partitions** of single-cell expression matrices; merge shards (concatenate/stack) to reconstruct the full matrix for a given source/organ.  
 > - `cell_metadata_with_mappings.csv` contains **standardized per-cell annotations** (e.g., tissue, disease, sex, cell type, ontology mappings).  
 > - `edge_index.npy`, `s_bio.csv`, `s_name.csv`, and `s_desc.csv` provide the **graph topology** (COO `[2, E]`) and **entity metadata** (biological sequences, names, descriptions).
