The diagrams in the OP are contrary to the understanding I have operated with my entire working life. This kind of misinformation (in the context of lutherie) is very discouraging as it makes meaningful conversation that much more difficult. Perhaps it is not so much misinformation as an example of how the lexicon of language shifts over time.

When I say quarter sawn, I mean what is shown in the “rift” illustration, yet no purveyor is selling “rift” sawn wood. To me, quarter sawn means the annular rings, viewed from the end, are 90 degrees to the surface. Slab sawn would have any part of the board with the annular rings parallel to the surface. Rift would be in between, particularly where the board is neither quartered nor slabbed. Most lumber that is not slab cut is rift, as for the purposes of lutherie, quartered wood must be actually quarter sawn across its entire width. If not, assuming it is not slab, it is what I call rift. There is an ongoing discussion as to what degree of perfection is required for material to qualify as quarter sawn before it no longer qualifies. I admit to being at the hardcore end of the spectrum as I need to see no more that 3 degrees of deflection to label wood as quarter sawn.

Run out is another issue altogether, and has no direct bearing on an end grain diagram.

My nomenclature is that of the woodworker. The nomenclature of the sawyer, which I do not speak, may be another thing all together.
