"no repositories found": cgit + gitolite + nginx -- git/ssh access OK, web access OK, no errors, but no repos found/displayed?

my current config is

	cat /etc/cgitrc

		enable-index-links=1
		enable-log-filecount=1

> can he access repositories owned by gitolite?

that was the _intention_, at least, with

	>     Users/groups are setup as
	> 	>       id wwwrun
	>         uid=30(wwwrun) gid=8(www) groups=8(www),475(gitolite)
	>       id wwwrun-cgit
	>         uid=474(wwwrun-cgit) gid=8(www) groups=8(www),475(gitolite)
	>       id gitolite
	>         uid=475(gitolite) gid=475(gitolite) groups=475(gitolite)

the systemd units for uwsgi service & socket are templated,

	/etc/systemd/system/uwsgi-app at .service
		[Unit]
		Description=%i uWSGI app
		After=syslog.target

		[Service]
		ExecStart=/usr/sbin/uwsgi \
		 --ini /etc/uwsgi/apps-available/%i.ini \
		 --socket /run/uwsgi/%i.sock
		User=wwwrun-%i
		Group=www
		Restart=on-failure
		KillSignal=SIGQUIT
		Type=notify
		StandardError=syslog
		NotifyAccess=all

	/etc/systemd/system/uwsgi-app at .socket
		[Unit]
		Description=Socket for uWSGI app %i

		[Socket]
		ListenStream=/run/uwsgi/%i.sock
		SocketUser=wwwrun-%i
		SocketGroup=www
		SocketMode=0660

		[Install]
		WantedBy=sockets.target

so that, in the case of app == 'cgit', they get enabled/started as

	systemctl enable uwsgi-app at cgit.socket

and, uwsgi/cgit execs as

	wwwrun-cgit:www

which, i thought, should make it behave with gitolite repos.

if not a bug, it's certainly possible i've missed some config, perm, etc.
