Register note
Supersedes the entry previously published as Cost Engine. A separate cost-engine component was withdrawn at architecture freeze: two homes for one calculation is how two calculations appear. There is one cost model, one owner, and the planner and the router optimise against that same model. Key retained so existing citations resolve.
