Persistent naming, step 1 (plan/adr/0002): faces are named from their history (a face lying on an input face keeps its name; new faces by role: F<feature>:side:<sketch curve>, :start/:top/:bottom caps, :blend:<edge>, …; split pieces #k along their spread), edges by the faces they separate (pieces ~k); names worked out lazily per body and shared by its clones; fillets and chamfers store edge names and resolve by name first (a split edge takes the piece nearest the picked point with a warning, a vanished one falls back to the point with a warning); model.faces and model.edges report names; tests for resize, suppress, reorder, an upstream split and a removed sketch segment
