If a bug were to make it into CentOS Stream, and identified before RHEL 
8.4 was released, would an updated/fixed package be produced and placed into 
CentOS Stream?

If a bug were to make it past CentOS Stream and into RHEL 8.4 and the bug 
is then identified and fixed after the release of RHEL 8.4 would an 
updated/fixed package be produced and placed into CentOS Stream in the 
same timeframe or only if/when updated packages and their dependencies 
were made/released into CentOS Stream for updated features for RHEL 8.5?

If the same happened in the previous question but was in a package or set 
of packages that was being rebased in 8.5 would it work the same way?

Thanks,
Barry

Absolutely. The only path into RHEL minor releases that isn't through Stream
is for CVEs and other embargoed changes. And those will go back into Stream
as soon as they can.

It might depend on the situation, but I would expect the fix to land
quickly in Stream.

Hmmm. I'm not sure I understand you. There won't be a dump of 8.5
packages
into Stream at some point. They will be updated there as ready.
