Orphan Blocks rate
What are the factors affecting the rate of orphan blocks?

Are stale blocks retained forever or are they "pruned" automatically at some depth in the chain?

However I noticed that I am including an…

Stale block verification at node level
It comes to my curiousity about how exactly the node A will mine block N+1 when he & node B generated block N (not in same time but) in a fairly close timeframe.
In many articles, it says that when 2 nodes (A&B) are generating the same height block…

Do nodes propagate stale blocks?
I read somewhere (but can't find now) that while a node might receive a stale block, the node won't propagate a block that it knows to be stale. Is that true?
If so I don't quite understand how a secret attacking miner, even if they did…
