so if there was any sand imbedded in the end grain, it got there on

after sawing but before planing?

Oh, it would certainly be my fault.

I don't have proper supports for working panel edges, so it was sitting
on a 2x4 to keep it off the shop floor and clamped against the edge of
the bench. It's entirely possible that the 2x4 wasn't as clean as it
should have been.
