CMR // CRITICAL MATERIALS ROUTER — NdFeB + Li
The attribute that makes the part survive a 150 °C motor — Dy/Tb substitution into the grain boundary — is the attribute that pins the part to the most concentrated node in the graph. Dropping Dy drops the temperature rating. That is the tension the router has to solve: hold Br, Hcj and Tmax, move the jurisdiction. Li₂CO₃ scores 80 for a different reason — the ore is Australian, the refining is not. Confidence is not a vibe — it is weighted coverage of exactly the attributes the buyer's spec envelope requires: Σ(w·tier)/Σ(w). Click any confidence figure or provenance chip to see the arithmetic. Two nodes carry the graph: CN separation sits on 205 share-points of downstream alloy mix; CN refining on 149. Dashed ring = pre-production. The shock happened. The buyer's line never stopped. Time from shock detection to committed reroute: 4.6 s of solver time; the previous process was an email from a supplier, on the supplier's schedule. A directory of suppliers decays the day it is published.
