# ruvector-sparsifier

> Incremental graph sparsifier that compresses large graphs into a 'shadow graph' preserving key properties like connectivity, cuts, and flow. Uses random walks for importance scoring, spectral sampling, union-find backbone, and periodic auditing to maintain accuracy without full rebuilds.
