Rolled out to matrix, authentik and monitoring, verified in two namespaces rather
than assumed: DNS resolves, federation still reaches matrix.org, the metadata service
is blocked, and the private path to 10.0.0.3 is intact with Alloy reporting no errors.
The issue stays open on purpose. Its actual demand - default deny with explicit
allows - is not met; egress is still open everywhere except link-local. Federation
makes that unwritable as a list while it stays open (#0060). What is now on record is
the inventory that makes the next decision possible: monitoring and authentik have a
nameable set of destinations and could take default deny, matrix cannot.
