Hydrosheaf: A Graph-Sheaf Framework for Assumption-Audited Groundwater Inference across Hydrogeochemistry, Tracer Ages, and Flow-Topology Uncertainty

HydroSheaf 0.6.0 HydroSheaf 0.6.0 is now released. Highlights Added evidence-gated active learning with explicit ABSTAIN decisions. Added joint sheaf-reaction inference with fixed transport maps. Added certified tracer design using worst-case ambiguity and budgeted minimax analysis. Added geology-aware field loading, DEM attachment, and UER audit tooling. Expanded regression and integration test coverage. Validation 1,064 tests passed; 1 skipped. Ruff checks passed. Wheel and source distributions built successfully. Lockfile and Git integrity verified. Release commit: 6630898d
