With "transition": "pyramid" (the default; "tie" keeps the old join) a tet cell is meshed after the hex cells, with a pyramid on every hex face of its cuts and its tetrahedra on the pyramids' sides: one conforming mesh, no tie. Where it cannot be built the cell says why (no_pyramids) and is tied. The apex height is 0.4 of the quad's edge, so pyramids on faces meeting at a right angle do not cross.
