panama-sudo is pkexec with a stated reason: the reason travels to the
shell over the existing polkit IPC target, and the prompt renders it
labeled "Stated reason (unverified)" beside polkitd's real action
message -- beside, never instead of, because any process can claim any
reason and the action text is the trust anchor. Reasons are single-shot
and expire in ten seconds, so a stale one cannot dress up an unrelated
prompt; without a reason, a running shell, or qs the wrapper is exactly
pkexec. Built for agents, so the person typing their password learns
what for. Verified live end to end -- reason shown, consumed once,
expired when stale, cleared on dismissal -- and pinned by the polkit
reason contract.
A mode is on because something is true right now: a game is running, a window is
fullscreen on a given display, a workspace is focused, the clock is inside a
window. That is asked again rather than fired once, and it is the whole reason
schedules could be included here without the usual failure modes. A machine
asleep at 23:30, rebooted at 02:00, or opened at 08:00 into a window that has
already passed all reach the right answer by being asked again; an alarm gets
all three wrong.
The midnight-crossing rule is the part worth being careful about: a window
belongs to the day it STARTS on, so a Friday-only 23:30-07:00 covers Saturday
morning and must not cover Saturday night. That arithmetic was tested as pure
logic before anything was built on it, including every malformed input failing
closed -- silencing someone because a time string was wrong is the worst way
this could fail.
This does not take over the manual timed session. FocusSession already owns
that, with its capsule, shortcut, Quick Settings entry and contracts, so modes
defer entirely while one runs. Two writers of Do Not Disturb would each restore
whatever the other happened to leave behind.
Gaming hands over rather than being duplicated. The hook was silencing
notifications itself, which would have made exactly those two owners -- and
Gaming.active only polls while its settings page is open, so a mode could not
have seen a game reliably in any case. The hook reports the game over IPC now
and the mode decides what that means, the Gaming page points at it, and
gamingSilenceNotifications is retired from the schema, since a setting nothing
reads is the dead row this work keeps removing.
Sleep ships disabled. A desktop that starts silencing someone on first boot has
overstepped, whatever the default hour.
Three contracts moved with it. gaming-contract asserted the hook uses setDnd,
which was right before and wrong now; the shell-side assertions that setDnd and
dndState exist stay, because a toggle would flip an already-silent machine back
on. The new contract is proven to fail by breaking the midnight rule and by
letting modes run alongside a manual session.

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.

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.

Super+Tab already cycled windows, but nothing was drawn, so you chose
blind and could only confirm the choice by arriving. A visible switcher
is muscle memory for anyone arriving from macOS or GNOME, and it was the
last item of roadmap phase 03 that did not need coordination.
Ordered most-recently-used, not by creation, because that is what makes
the gesture useful: one Tab returns to the window you just came from.
Hyprland does not report an MRU order, so it is tracked from focus
changes and keyed by address, which is the only property stable for a
window's lifetime.
The gesture needs three binds rather than two. Tab steps the selection,
and the switch is committed on Super RELEASE -- the only way the
compositor can say the gesture is over. That bind is on the bare
modifier, so it fires on every Super release in the session; commit()
returns immediately when nothing is open, which is what makes it
affordable.
A list of names rather than thumbnails: at a glance you are looking for
"the other terminal", and a row of live previews is slower to read and
far more expensive to draw than this gesture deserves.
The interesting part is the bug. The overlay was built, mapped nothing,
and logged absolutely nothing -- because it declared `required property
var screen` while Variants supplies `modelData`. shell.qml has carried a
comment warning about exactly this since the Bar hit it, and I read that
comment earlier in the same session and still walked into it. A comment
that does not stop the person who read it is an argument for a test, so
per-screen-surface-contract now checks every per-screen delegate takes
its screen from modelData. Verified it catches the exact mistake.
Also fixes a regression from 8be3fc2: settings-pages-contract still
required vitalsIntervalMs on Home, where it no longer is. That contract
was pinning the split-across-two-pages arrangement the same commit
fixed, and I pushed without running it.

Panama had grown into three configuration surfaces that only agreed because
they had been typed to agree: looks.lua hardcoded values, DesktopPreferences
independently defaulted the same values, and SystemSettings replayed them at
startup. Nothing kept them in sync, and the Lua side read no shared state at
all. This lands the first three stages of docs/superpowers/plans/2026-08-17-panama-cohesion.md.
Fix silently failing Hyprland writes. On a Lua-configured Hyprland, hyprctl
keyword refuses the write, prints the refusal to stdout, and still exits 0, so
the HDR, VRR, and direct-scanout toggles persisted their value and reported
success while the compositor never changed. Writes now go through hyprctl eval,
which has the same hazard on syntax and runtime errors, so success is defined
as reading the value back and finding it equal. The existing contract passed
throughout the outage because it re-applied the values already in place; the
new one flips each value to something it does not hold.
Derive preferences from a schema. Every setting used to be restated four times
-- a property alias, a JSON adapter property, a change handler, and a line in
reset -- where omitting any one failed silently. PreferenceSchema.qml is now
the single source, and persistence, validation, reset, and the Hyprland mapping
all derive from it. Unknown keys on disk survive a write so a rollback does not
discard a newer build's settings, and a corrupt file falls back to shipped
defaults. The store moved to ~/.config/panama/settings.json, migrating from the
old state directory without deleting it.
Share that file with Hyprland. prefs.lua reads it at config time with every
shipped literal kept as the fallback, so the config still stands alone. The Lua
is the default, the JSON is the truth, and Settings is the editor. The
compositor-adjustable surface goes from 3 keys to 23.
Also fixes two test-hygiene bugs found by running the suite end to end for the
first time: settings-pages-contract could see the window settings-window-contract
leaves behind, and the new write contract was persisting its deliberately-wrong
values into the user's real store.
