Law
Computational Law maps the structural, computable foundations of US law for engineers and CS readers: sources, citation graphs, procedure flowcharts, deadline arithmetic, and legal-analysis frameworks. Each book treats diagrams as simplified models with jurisdiction caveats and a not-legal-advice stance: models, not law. The track's firewall doctrine is RENDER STRUCTURE · REFUSE INTERPRETATION · CITE · ABSTAIN · HAND-OFF.

Operations Research / Optimization
Operations research from its exact optimum outward — starting with linear programming as geometry, where a two-variable LP's optimum sits at a rational vertex of the feasible polytope, proven by the constraints themselves rather than read off a solver's float, with every value pinned and every diagram validated.
