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.

Live first, because unlike every other page here this one has a live
dimension: card temperature, power draw, whether Game Mode actually
engaged. It polls only while it is open, since a settings page nobody is
looking at has no business waking the CPU.
The part that makes it Panama's page rather than a gamemode config
editor is the hook. gamemode runs a script when a game asks for it and
another when the game exits, so the power profile switches to
performance and notifications go quiet for exactly the duration of a
game -- and afterwards both go back to what they WERE, not to a default.
A Do Not Disturb someone set by hand survives a game; a power profile
someone chose is restored rather than replaced. Verified against real
gamemode activation, not merely by calling the hook.
Two things the page reports rather than hides. Game Mode's headline
trick is switching the CPU governor to performance, and this machine
already runs performance, so it says so instead of implying it helps.
And Proton builds are listed but never chosen: Steam picks the runtime
per game, and a control here would claim an authority this page does not
have.
The hook first called a notifications function that did not exist, and
the one that did was a TOGGLE -- the wrong primitive entirely, since
toggling at game start would unsilence notifications that were already
silent. The shell gained an explicit setter and reader.
search-routing-contract kept its own hand-written list of every page,
which made adding one fail as "not a known page" -- a sixth place to
register a page and a sixth chance to forget. It now derives the mapping
from the shell, which already knows it.

The machine runs essentially every popular self-hosted service, and on
looking at them the batch was revised once and then dropped. Almost all
of it is infrastructure for other services rather than anything a
desktop consumes -- whisper there feeds Bazarr subtitles, not dictation
here -- the desktop has the better GPU anyway, and the one genuinely
desktop-shaped idea is already solved by an installed application.
Recorded rather than deleted so it is not proposed again, with the
lesson that matters: a service existing is not a reason to integrate it.

hyprpolkitagent's dialog is compiled into its binary -- no config, no
stylesheet, nothing to theme -- and it was the one window on this
desktop that looked like it belonged to something else.
The split between the two halves is the security design, not an
implementation detail. A small agent process owns the D-Bus side: it
registers with polkitd, receives the request, and hands the shell the
action, the message, who may answer, and a one-time cookie. It never
sees a password. The shell draws the prompt and, on submit, spawns the
setuid polkit-agent-helper-1 itself and writes the password to that
helper's stdin; the helper runs the PAM conversation and reports to
polkitd directly. The password exists in the shell and in the helper's
stdin and nowhere else -- never on a command line, never over D-Bus,
never through IPC arguments.
The prompt takes exclusive keyboard focus, because a password field that
lets keystrokes reach the window behind it is a keylogger with extra
steps. The request travels as a file created 0600 with O_EXCL inside a
0700 runtime directory: a cookie is not a password, but it is a
capability, and capabilities do not belong in a process listing either.
Three things cost real time. polkitd calls back on the same connection
that registered, so exporting the object on the session bus while
registering from the system bus failed every request as "Not authorized"
with no error anywhere. XDG_SESSION_ID is absent in a systemd user unit,
which runs under [email protected] and belongs to no login session, so the
session comes from logind's Display property instead. And PyGObject does
not accept the @ placeholder in variant format strings.
hyprpolkitagent stays installed as the fallback, only one agent is
started, and the comment beside the autostart says how to get the stock
prompt back. Verified end to end, including a real password accepted and
three cancellations refused.

Three sources that fail independently, so they are counted and applied
separately: a flatpak mirror being down says nothing about whether a
kernel security fix is waiting. Blending them into one number would hide
exactly the case that matters.
Checking costs about nine seconds, which is too long to spend every time
a page opens, so the page opens on the last result and says when it was
taken. A first visit with nothing cached goes and finds out rather than
showing a confident "up to date" it has no basis for.
Installing packages takes a snapshot first, named after what is about to
happen, so Snapshots shows "before 32 package updates" rather than a
timestamp. Best effort: a machine without snapper still updates, because
an update that refuses to run when a nicety fails would be worse than
one without a restore point.
Automatic updates cover applications only, through a Panama-owned user
timer running daily with a randomized delay. Packages still ask, and
dnf-automatic is reported as absent rather than offered, because
installing software is not a settings action.
Health gained a check, and that is where the bug was: it first returned
status "degraded", which is not in the doctor's vocabulary of ok,
warning, error and unconfigured. It was counted as nothing at all while
the summary still said healthy -- the same silent no-op this codebase
keeps relearning. A contract now asserts every status a check can return
is one the doctor counts, and the doctor's own contract knows about the
new check rather than failing on its arrival.

Parity is done except for Color, which the platform blocks. This is the
other direction: what a settings application should own on a machine
whose owner runs the servers.
Every item was checked against this machine before being written down,
including the one that was dropped -- a VPN page, because the WireGuard
tunnel lives on the router and neither wg nor tailscale is installed
here, so it would have had nothing to drive.
