Data Tree still confuses me. I have to write it in two identical streams.
If anybody has an interest, please tell me how to simplify this definition. Thanks!

if I have understood your concern correctly, the point is the Pattern data propagates only inside existing branches, it doesn’t propagate by creating new branches, but just repeats the last branch (as GH standard):

so we have to initialize a new pattern for each branch

Thank you very much!

The tree structure of the two data is different, yet they can be fed into the Cull Pattern and everything is OK. It is confusing me.
I was close to your logic at first and then stopped here.
Why is it OK? Why?

letìs go crazy: jagged data trees for the win

renumbering one data tree at a time:

I like you script much clearer and simpler, thank you HS_Kim

I tried to redo your script and it turned all red and the shift (chess like) did not work. Please let me what I did wrong.

A slightly different approach

So Cull Pattern component renumbers the path!

I understand! Thank you very much!
