No it is simply completely off topic here, this list is about luatex and
your question is about latex applies equally to all the tex engines.

 As I tried to show in the stackexchange answer the other day, it is called
but it is empty at that point.

but after changes,which proposed David

It is not an issue that needs solving, it is by design.  \everypar is not a
user level command it is a low level tex primitive and latex uses it to
accomplish the shaping of list item, and so the values you entered are
lost. I showed how you can set things up to preserve your tokens without
breaking the list implementation.
