mesh/delivery-group group fix/154-local-network checking: 0 of 2 member(s) ready
mesh/merge-gate out of date: judged against trunk 1826b68a22b5, the trunk is now 404b4409e70e; judged again on a recheck or when it is merged
mesh/repo-check out of date: judged against trunk 1826b68a22b5, the trunk is now 404b4409e70e; judged again on a recheck or when it is merged
mesh/delivery superseded: a newer head of the same pull request
A local service could only be declared public, which says the internet. local-network is a source and a reach: the private network and the private networks the machine reported on a link facing outside, judged here, shown by plan and node, and said in the rule set when there are none.
