Listing zones and services is what firewall-cmd already does. The
question it does not answer needs both halves at once: a port is
reachable only when something is LISTENING on a network address AND the
firewall permits it.
On this machine that crossing is the whole story. The rules look
unremarkable -- one zone, three services, a port range -- and what they
mean is that PostgreSQL and Redis, published by rootless containers on
every interface, are reachable by anyone on the network. Neither half
says that alone, which is exactly how a tidy rules list coexists with an
open database. Nothing was misconfigured: Fedora's default zone met
podman's default publish behaviour.
Ephemeral client sockets are excluded. A browser's outbound UDP port is
indistinguishable from a service in ss, and listing twenty of them
buried the two rows that mattered.
Closing the port range names what it would cut off, by service, before
doing it, and removing ssh says so when someone is connected over it.
Rich rules are shown and never edited: a syntax is not a setting, but
hiding it would misrepresent the configuration.
The contract needed a recorded firewall, and the reason is worth
keeping. The rule this page exists for cannot be tested against this
machine -- its zone permits everything above 1024, so "listening" and
"listening and permitted" give identical answers, and a blocked listener
needs a port below 1024, which needs root. With the crossing deleted,
the contract passed. It now runs against a fixture where two listeners
are blocked, and catches it.
Also here: polkit response files are written 0600 rather than at the
default mask, the agent sweeps requests left by an instance that did not
exit cleanly, and the write sweep waits for its harness to be ready
instead of reporting the startup race as settings that failed.

A suite runner walking the tests directory executes it with no arguments
and gets an IndexError, which reads as a failing test rather than a
helper being used wrongly.

The audit that followed "some things in the settings app don't work".
Sixty-five settings reach the compositor and five of them were checked
against it. The rest were covered only by tests that read source text,
which is exactly where a dead setting hides: the write no-ops, nothing
fails, nothing logs, and the row simply does nothing.
The sweep drives each setting through SystemSettings.commitPreference --
the entry point a settings row uses -- flips it to a value it does not
hold, reads it back from the live compositor, and puts it straight back
before touching the next one. Settings Panama stores itself get the same
treatment against the store, since a value that fails to persist is the
same dead row from the outside.
Result: 61 of 63 compositor settings verified against the running
compositor, and 51 stored settings round-tripped. No failures. The
breakage was confined to the Applications page, which is fixed.
Proven able to fail before being trusted: with commitPreference stubbed
to return true without applying, 61 settings are reported; with the
store stubbed to return nothing, 51 are. A one-second settle window
keeps a slow read from being reported as a dead write, which it briefly
was.
Also here: control-center-contract asserted the literal margin
expression that made the panel hang 38 pixels below the bar, so the
contract and the code agreed and the bug was invisible to both. And
settings-page-registry-contract is deleted -- settings-nav-contract
already checked those files and more. It would have caught the Storage
page omission if I had run the suite instead of a hand-picked subset.
