Hello,

when we move c10s packages e.g. from AppStream to CRB, their older versions remain in the old mirrored repo.

See for example:

$ repoquery q --repo=c10s

{baseos,appstream,crb}

--queryformat='%

{reponame}

\t%

{name}

-%

{version}

-%

{release}

' python3-pytest
c10s-appstream python3-pytest-7.4.3-3.el10
c10s-crb python3-pytest-7.4.3-3.el10
c10s-crb python3-pytest-7.4.3-4.el10

This is from https://mirror.stream.centos.org/10-stream/AppStream/x86_64/os/Packages/

The package is not in https://composes.stream.centos.org/stream-10/production/latest-CentOS-Stream/compose/AppStream/x86_64/os/Packages/
