Detailed Description

Per-face data the shared optimizer knows nothing about.

Whether a face is tracked surface, which surface, and which bbox side it is on all live on wmtk::SurfaceTagAttributes. Only the construction label is the offset's own, and only the pre-optimization phase reads it (marching tets, simplicial embedding, the offset growth in Spatial.cpp) – optimize_offset() consumes it once and ignores it from then on.

Registered with the base's m_face_attr_group, so it survives the mesh changing shape. Its VALUES, though, are only maintained by the offset's own operations: the shared split, collapse and swap propagate face data by copying SurfaceTagAttributes around and never see this. That is sound precisely because the label is dead by the time they run.
