It might be nice to emit a warning here since we'll
only hit this case if something fishy is going on
with the saved lr.

Yeah, something fishy is going on if that ever happens.  Let me create
a V2 with an additional print.

FWIW, I ran into another bug on -next when trying to update this.

Report:

Fix:

Then I got bogged down in planning for plumbers and other fires. I
hope to revisit the series after plumbers.
