You don't show the @panel_config but assuming it's within the boundaries of one
of your calls to config.scan() then the issue is that pyramid's "scan" function
by default scans for "pyramid" decorators and pyramid_layout registers its
decorators under the "pyramid_layout" category. This means you should adjust
your scan for panels to include that category:
config.scan("myapp.panels", categories=("pyramid", "pyramid_layout"))
See
https://github.com/Pylons/pyramid_layout/blob/202a291bbb947e7f5c43c5216878331987508f05/pyramid_layout/panel.py#L36
and
