Chicken or the egg. May have broken out cuz of decay and or major borer damage.

That is sapsucker damage.

Not saying there wasn't something else going on with the tree...but those rings were sap sucker - returning to the same tree - why the discoloration goes throughout the years.

Sapsucker does things symmetrically for sure but the tendency is to produce grid like columns and rows.
I vote a borer.
