Vendored Dependencies

GeoSC vendors Microsoft’s SparseSC under src/sparsesc/ from https://github.com/microsoft/SparseSC at upstream commit 3b4d2ebd87b41fc8e0ec3e97fcb2be1b689275c0. It is a governed integration fork. The authoritative local modifications and update procedure are recorded in src/sparsesc/PROVENANCE.md.

Changes to the vendored tree require a provenance update and wrapper-boundary verification. It is excluded from first-party formatting and typing checks. scripts/verify_release_candidate.py exercises the maintained integration surface; passing that gate does not validate a client design.

src/sparsesc/utils/AzureBatch/ remains part of the governed fork. Removal requires a separate SparseSC provenance-backed phase.

SparseSC retains the MIT licence notice from the pinned commit. Wheels and source distributions include that notice and the provenance record. GeoSC’s separate proprietary licence does not replace the rights granted by the third-party notice.
