NOTEARS linear-SEM chain conformance

Suite path: conformance/discovery/notears_chain

Synthetic static discovery fixture: continuous tabular SEM x0 → x1 → x2.

Comparison class: RequiredDirectedEdges (true directed edges must be recovered; extras capped by max_false_positive_edges). Not an Exact upstream NOTEARS oracle pin.

Generator: scripts/conformance/generate_notears_chain.py (see expected.json → reference.command).

Expected summary

Top-level keys: algorithm_id, generation, max_false_positive_edges, n, notears, notes, reference, scm, tolerance_class, true_directed_edges, variables (11 fields).
