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.

src/synthdid/, if retained in a checkout, is not used by the primary GeoLiftAnalyzer workflow and is not a documented estimator option.
