ShastrySutherland — model index
Spin-½ Shastry–Sutherland model on the Shastry–Sutherland lattice (corner-sharing-orthogonal-dimer geometry; realised in SrCu₂(BO₃)₂):
H = J Σ_{⟨i,j⟩} Sᵢ · Sⱼ + J' Σ_{⟨⟨i,j⟩⟩_d} Sᵢ · Sⱼ.Generated by docs/atlas/generate.jl — a pure VIEW over the *_registry.jl claims + the static test/INVENTORY.jsonl AST scan. No test is executed and no src is run; test/INVENTORY.jsonl is regenerated in-place (idempotently) from that static scan; fetch/@register untouched. Assurance labels are PROVISIONAL: residuals / confidence are not shown yet (RES not wired). Badges reflect the committed test AST, not the latest CI run — a hub can read green while its @test is red between regenerations. @sweep = a graceful regime-resolution gap, not card omission.
All (Quantity, BC) hubs src claims for ShastrySutherland. Cells link to the per-hub card; — = not yet implemented at that BC. The shape of the matrix is the gap visualisation: empty cells are where physics could be added next.
