An X11 window in a Flatpak can give KWin an app id with no desktop file:
RustDesk's says com.carriez.flutter_hbb (its GTK application id), and the
Flatpak's desktop file is com.rustdesk.RustDesk. A profile recorded that
id, so it couldn't relaunch the app (PR #16 keeps that from killing
ft-floatd's socket). And the window's pid is the sandbox's own, so a
launched window matched neither by process nor by app id, and didn't
float.
desktop_name() finds the desktop file whose StartupWMClass names the
window's class (or app id) when the app id has none. Capture records
that name, a profile claims open windows by it, and a launch's window
matches by it.
Profiles saved before this keep the old id; save them again.

- floating-windows.md and profiles.md describe what's built, with what
isn't listed as such; the plans, phases, and branch notes are gone
- hands-migration.md is gone: the move is done; its open items are in
hands/README.md's Known issues
- reference.md: Layout & profiles, every action, key combinations,
floating windows, the gaze pointer, and hand tracking as they are
- design.md gets the KWin findings from floating-windows.md
- README, gaze/README, AGENTS, hazards, gaze-controllers, and the
example config catch up with gaze, hands, and the stuck-key fix

KWin's PlacementTracker keeps each window's geometry, full screen and
maximized state per layout of the outputs, and puts windows back when a
layout it has seen comes back. A spare output resizes after its window,
so resizing a floating window back to an earlier size (or changing its
scale, or full screen) made the window and its output flip forever, and
floating or docking one window could move others onto or off a spare.
The KWin script now keeps where each window belongs, reports nothing
while KWin changes the outputs, and on screensChanged puts floating
windows back (and the screens' windows when only spares changed),
cancelling KWin's requests before the app sees them. A size asked for is
held for a second against late answers.
With that: a launched app and a profile get their remembered scale back,
scale steps keep the size in pixels, ft-floatd waits for the end of an
edge resize before resizing the output (KWin cancels the resize on any
output change), a window taken over after a restart keeps its app and
panel density, and `ft-float float ID` asks the script for the window's
current place.

- KWin 6.2's scripts have no maximize mode: a window counts as maximized
when it fills its output's maximize area.
- A late event for a window that just closed brought it back into
ft-floatd's table, so a profile "found" it open, floated a window that no
longer existed, and held a slot. The script doesn't report deleted
windows, and ft-floatd ignores events for ids it has seen close.
- Docking a window that came from a screen that's hidden now puts it on the
first screen that shows instead.

A profile is a named layout plus the screens it hides and its apps' windows
(docs/profiles.md). ft-layout save captures them (ft-floatd's "windows",
after the KWin script reports every window as it is now); use opens them:
the screens move, open windows of each app go to their places (on a screen,
maximized or not, or floating), and missing apps start, once and then again
for each window still missing 3 s after the first. Nothing closes.
The desktop starts in FT_PROFILE or default_profile (ft-layout start, from
the session script). Each profile gets a launcher entry (Frametop: NAME, in
SteamVR's Launch a program list) that switches to it or starts the desktop
in it. The relay's profile:NAME action and Input Settings' "Open profile"
entries put one on a key, mouse button, or controller button. Display
Settings' Layout page becomes Layout & profiles: Save as profile, Open
profile, the profile's apps, and Start in profile. Plasma's own session
restore is off in the Frametop session.

The input relay owns the float key now: float_toggle (Meta+Shift+F unless the
rules have their own key combinations) floats the window under the pointer, or
the active one over the wallpaper, and docks it if it floats. dock_all puts
every floating window back. Both are mappable to mouse and controller buttons,
and work without pointer mode. The KWin script no longer registers a shortcut,
and ft-floatd drops the old one. Key combinations move to Input Settings'
Keyboard page.
docs/floating-windows.md records the decisions from 2026-09-30 (the title bar
button, Launch as Standalone, profiles), and docs/profiles.md plans profiles.
