Diagnostic tool for finance ministries testing whether their national tax code actually supports the climate commitments their country has signed. Ingests the body of fiscal law and tests each material provision against the stated targets. Classifies every provision by its relationship to those commitments: complementary, countervailing, overlapping, or redundant. Surfaces cross-rule interactions between them.

Each finding paired with a steelman counterargument so reviewers see the strongest defense of the status quo before recommending change. A composite grading mechanism rolls per-provision findings into a single coherence score and letter grade, weighted by material impact and confidence tier. A built-in reform simulator lets policy teams assemble a package of edits and adjust intensity live, watching the grade, distance-to-target, and emissions trajectory recompute in real time.
