Our first 'almost' block - but it wasn't good enough.
ckpool submits the share as a block if it is within a small amount of being a block just to be sure.
So it shows up on the web site, but alas not good enough.
share block was: 52123573961.901596
but current diff is: 52278304845.59168243
It will show up as an orphan, but I guess I need to label it as something else later since it's not an orphan.
I saw that on the block page on your website and wondered, thanks for the clarification.
I recall a similar thing happening on the ck solo pool, where a "close" block solve was submitted but ultimately reject. Close but no cigar!
