§ 01 / 03 · PIPELINE
Defect → strategy → fix
The classifier reads the mesh's topology, not its shading. Each defect type triggers a localized operation from a small, audited fix DAG. No global remesh, no UV rebuild — your bakes survive.
FIG. TD-01 · defect classification → repair DAG → interchange-clean USD · topology-aware operations only · UV / material / UDIM preserved
FIG. TD-02 · 4-check hazard taxonomy · self-intersection · pinch-off · curvature spike · Euler violation · severity-scored
FIG. TD-03 · weld solver · Hungarian optimal vertex assignment with max-distance gate · zforge/topology/weld_solver.py
