On the Frame, a SteamOS update replaces SteamVR, KWin, and gamescope with the
rest of the OS image. scripts/update-check.py, run by doctor.sh and report.sh,
checks what Frametop uses from it: the OpenVR interface versions the installed
programs were built against, the vrcmd --overlays format, the eye tracker's
shared memory layout, host files, services, sockets, and the driver
registration. doctor.sh --mark-good records the package versions once things
work, and later runs say what changed and what to try by hand.
The session no longer stops when mesavars.sh or flatpak.sh is missing.

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.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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.

ft-screens: "conceal <screen|all>" hides a screen on its own, whatever the
visibility mode or the hotkey says, until "reveal"; "concealed" lists them.
(Not "hide N": older builds read anything starting with "hide" as the hotkey.)
ft-layout keeps it per screen ("hidden" in the layout), applies it when it
arranges the screens, and has hide/show N|all and hidden. Display Settings
gets a Shown switch per screen on the Visibility tab. ft-floatd floats a new
window that opens on a hidden screen, and puts a stray window on a screen
that shows. Profiles (next) use it to show only some screens.

ft-float launch APP / run COMMAND: ft-floatd starts the app and floats its
first window (matched by process or desktop file name for 30 s) where that
app last floated, or in front of you at the primary screen's density. Each
app's place (pose relative to the primary screen, size in pixels, scale) is
kept in ~/.config/frametop-float.json whenever one of its windows stops
floating; the scale isn't applied yet, since rescaling can loop (written up
in docs/floating-windows.md, Known problems).
Launch as Standalone (float/ft_apps.py): the session writes copies of the
apps' desktop files with that action and puts them first in XDG_DATA_DIRS,
so it shows in the Application Launcher's and the taskbar's right-click menus
in the Frametop desktop only. ft-floatd rewrites them when apps change.

- The decoration's "bottom" property clashed with Item's (KWin refused it).
- No On All Desktops button with one virtual desktop, like Breeze.
- decoration/apply.sh finds the session's D-Bus through plasmashell (KWin's
environment isn't readable), and installs each try under a new name: KWin
keeps a decoration's QML by name until it restarts.
- ft-floatd starts its script with Scripting.start: after a reload, the new
script gets the old one's id while the old one is still being deleted, so
run() on /Scripting/Script<id> went to the old script and the new one never
ran (a second ft-floatd start left floating windows without their script).
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Frametop's own window decoration (decoration/), a QML decoration for KWin's
Aurorae engine drawn like Breeze, puts a float button left of Close. It's the
Keep Below button with its own glyph: the KWin script floats a window when
keep-below is set and docks it when it's cleared, and keeps the flag set on
every floating window, so the button shows "back to the desktop" there. The
session script installs the decoration for the Frametop desktop only;
decoration/apply.sh switches a running desktop to it or back to Breeze.
Not yet tried in a running KWin.

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.

Steam reads the Frame controllers itself, outside SteamVR's bindings, and every
press and release it sees takes SteamVR out of laser mode, so controller clicks
at the gaze can't be done cleanly (docs/gaze-controllers.md, from the gaze-first
branch's tests).
- Gaze precision and Gaze drag take a mouse button or a key combination only;
the controller source, its aim steering, and POINTER_PRECISION_GAIN,
POINTER_PRECISION_DEADZONE and POINTER_GAZE_DRAG_GAIN are gone.
- The gaze actions (including Gaze pointer on/off) can't be mapped to controller
buttons: the relay ignores them there and doesn't ask the helper for those
buttons, and Input Settings no longer offers them.
- Last used wins in gaze mode too: picking up a controller hands it the laser,
as docs/design.md already said.
- The gaze dot shows all the time (POINTER_GAZE_DOT=always, the default;
moving brings back the old behaviour), with a switch on the Gaze page.

The local RDP login between krdp and the VNC bridge uses the account's
own name instead of "steamos", its certificate the hostname instead of
"steam-frame", and the ft_pointer driver installs under the user's home
instead of /home/steamos. The remote-access address already came from
the tailnet (tailscale0 and tailscaled's local API).
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A GTK 4 / libadwaita app (remote/ft-remote-settings, on the host's own
Python like the gaze probe): remote access on and off (REMOTE, applied at
once when the desktop allows it), the tailnet name and address to connect
to, and the VNC password shown, copied, or replaced. The password stays
random and made on the Frame, in ~/.config/frametop-remote; none is in
the code.
session/remote-ctl.sh starts, stops, and reports remote access; the
session uses it and leaves a remote-capable marker, since KWin allows the
capture only in a desktop that started with REMOTE=1. The password
between krdp and the VNC bridge (local only, but on krdp's command line)
is now new at every start. The installer adds the app to the menu.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
krdp streams every screen, so the VNC screen is now the primary's size and the
FreeRDP window is shifted so the primary fills it (ft-layout remote-view gives
the offset). It resizes and reconnects when the layout changes. With remote
access on, KWin's D-Bus screenshot interface is open too, for scripts that look
at the screens without the headset.

The hand role the pointer takes isn't something to choose by hand. The
helper still reads POINTER_ROLE (right by default) for experiments.
Tried and reverted (not committed): in gaze mode, taking the stylus role
by reconnecting. SteamVR gave the device no role at all (hint 5, role
none) and kept the dashboard laser on the held controllers, so the mouse
couldn't click either. The dashboard laser needs a hand role, and a held
Frame controller takes its hand's.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Two new actions for mouse buttons, controller buttons, and key
combinations: gaze_precision (hold: the pointer stops where you look and
the button's device steers it, a controller by where it points at
POINTER_PRECISION_GAIN, the mouse by its moves; release: click there) and
gaze_drag (the same with a real press at once, dragging until the
release). The relay sends "precision|gazedrag <source> 1|0" to the
helper, which runs them through the same holds as pinches and grips.
- Key combinations on any keyboard ("key_bindings" in the rules, e.g.
Ctrl+Alt+G for gaze on/off): the last key isn't typed.
- POINTER_GAZE_MOUSE: in gaze mode the left button is a precision button
(the default, as before) or clicks right away (direct).
- In gaze mode a moving controller no longer takes the pointer away.
- POINTER_ROLE (right, left, stylus): the driver takes a "role" command,
so the pointer can stay off the hand holding the precision controller,
which would otherwise take the role back. Needs the rebuilt driver.
- Input Settings: the actions on the Controllers and Buttons pages; on the
Gaze page the mouse choice, the role, the precision sliders, and key
combinations (captured from any keyboard).

Hand tracking no longer starts with SteamVR: hands/run.sh install leaves
the units disabled and links hands/ft-handsctl into ~/.local/bin, which
turns it on and off (on | off | status | log | cutouts on|off | gestures).
With it on, hands show through the screens; pinches and grips move the
pointer only with POINTER_HANDS=1, now off by default. ft-camd's service
runs the mono cameras only: while the headset is worn, the colour module
writes just a half-size image into the top-left quarter of its buffers,
which ft-camd can't use yet.

- The palm-down filter is off by default: the user's deliberate pinches,
hand raised, read 0.90-0.99, like typing.
- Typing is told apart by the keyboard instead: the input relay sends the
pointer helper "typing" on key presses, and it takes no pinch within
POINTER_PINCH_TYPING (1 s) of one.
- Grips are still held to hands raised (POINTER_GRIP_BELOW, 0.35 m below
the eyes); pinches aren't, since the user's own sat 0.35-0.45 m below,
elbow resting.
- A grip doesn't begin with the thumb on the index tip: that's a pinch
with the other fingers curled, which was taken for a grip.
- A pinch's point is the index and middle knuckles: the tips' midpoint
moved 1-2 cm as the pinch opened, dragging every release off its press.
- ft-hands --gesture-log prints what the detectors measure, 10 times a
second.
Pinches still aren't reliable enough to use; hand tracking is parked for
now in favour of the controllers.

Pressed when the pinch closes, released when it opens, its hand dragging
the pointer in between (at the pinch gain, past the dead zone), like the
mouse's button. That's what the gaze probe's Click practice needs: it
freezes its own gaze dot at the press and drags it by the pointer's
movement until the release. With gaze mode on, the pinch still holds the
press back and clicks on the release.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The pointer helper reads ft-hands' gestures. A pinch holds the pointer
where the gaze put it and clicks on the release; held, the hand nudges
the pointer at half its angle past a 1.5 degree dead zone, which also
teaches the gaze tracker. A grip presses where the pointer is, drags with
the hand, and releases when the hand opens, unless it began more than
30 cm below the eyes (hands on a desk). Hand movement is taken in the
room with the head pose at capture time. Hand use keeps the pointer from
the relay's idle release, as gaze mode does. POINTER_HANDS and friends in
frametop.conf.

ft-hands tracks with the mono IR cameras in dim light and with every
camera (or the colour pair, HANDS_BRIGHT) in bright light, going by the
colour frames' mean brightness with hysteresis and a 2 s hold
(HANDS_CAMERAS=auto, the default; mono, color and all fix it). Colour
frames are placed on the mono cameras' clock by their dequeue time, and a
view in a camera a step lacks waits for that camera's next frame.
A grip (a closed hand) is a second gesture next to the pinch, in version 2
of the gestures file: every fingertip curled toward the wrist, beginning
only on a hand seen open within a second and held up in front. On the
2026-09-30 lit recording that leaves 6 false grips of 14, all with the
hands on the desk; pinch counts are unchanged. ft-handreplay logs grips
and finger curl, watch_gestures.py shows them, and tools/cut_sets.py
copies a few sets out of a recording.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A colour camera probes at most 4 buffers a frame (each probe syncs a
~9 MB buffer's cache, which made the mono cameras miss frames), and one
that goes stale twice in a row is paused (10 s, doubling to 160 s) and
learned again instead of ft-camd exiting. The colour cameras run at 2 fps
until a reader asks for more in frametop-hands/color-fps, which saves
most of their decoding while only their brightness is needed. Each mono
camera's latest near-black frame's mean goes in the ring (dark_mean), a
measure of the room's IR light. The service now starts with --with-color;
HANDS_CAMERAS=mono leaves the colour cameras out.

Hand tracking (ft-camd, ft-hands, and their tools) joins the desktop. The
hands file and ring move to /run/user/UID/frametop-hands/, which ft-screens'
hand cutouts now read.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- The runtime files move to /run/user/UID/frametop-hands/: the desktop
session deletes /run/user/UID/frametop at every start.
- The cutout copy shader runs at highp: mediump (16-bit on Adreno)
stepped 1.7 texels across a 3440-pixel screen.
- One hand no longer pinches both sides after its left/right call flips
mid-pinch, and --pinch-palm-down (0.6) holds back pinches with the palm
facing down (typing on a lap keyboard).
- ft-camd judges a colour frame fresh by its luma rows only, and logs
per-buffer changes at stale colour frames with FT_CAMD_DEBUG=1.
- hands/run.sh caps skips the setcap when ft-camd already has them.
- The replay tool dumps poses (--poses), and its pinch events carry the
hand id.

Floating windows join the keyboard and the hand cutouts. Floating panels
don't get cutouts yet: their panel and popups show crops of the client
buffer (texture bounds), which the side-by-side cutout buffer doesn't
match. KWin gets both the spare outputs and our input method, and the
pointer helper's frametop. prefix already covers the float panels.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Fixes#7: SteamVR's keyboard never came up for the desktop's apps, and
opening it for our panels doesn't work well on the Frame (it's Steam's own
panel, mounted in the dashboard's scene, it follows the laser between
panels, and it takes the controllers over to SteamVR's laser).
- KWin starts input/ft-textinput as the desktop's input method. It tells
the input relay when a text field gains or loses focus, and the relay
asks ft-screens to open or close the keyboard. The session drops the
QT_IM_MODULE=xim and GTK_IM_MODULE=xim that the gamescope session sets,
or Qt and GTK apps never report text fields.
- The keyboard is ft-screens' own panel (screens/keyboard.cpp): a US laptop
layout, typed with a controller's laser or the 3D mouse. It opens 0.7 m
in front of you, below your eyes and facing you. It has a grab bar to
move it, a Close key, latching Shift, Ctrl and Alt, and repeat on a held
key. It's drawn into shared DMA-BUFs, so it doesn't flicker. Its keys
reach the focused screen as key presses, so every app takes them.
- It steps aside while the Steam menu or Steam's own keyboard is up and
comes back after. A layout reset closes it, and it doesn't open without
a head pose.
- Frametop Input Settings has a Keyboard page: open it for every text
field, only while no keyboard is connected (the default), only from a
mapped button (the new Open/close keyboard action, for mice and
controllers), or never. A switch keeps it open until you close it.
- The pointer helper treats every frametop.* overlay as a real panel. The
keyboard's shared texture reports 0x0 like SteamVR's scene-graph
controls, and the helper had given it their wide catch radius.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- KWin's nested backend makes an output the size it's configured to times its
scale, so after Meta+scroll every size ft-floatd sent was multiplied again,
and an odd result disconnected KWin (buffer not divisible by its scale).
ft-floatd now asks for sizes in the output's scaled terms (kwin_size), and
asks again after each scale change.
- SteamVR reports mouse positions on a panel with texture bounds in the whole
texture, not the crop, so clicks on a floating window landed up to ~200 px
off. The mouse scale is now the buffer's size, as on a screen.
- A floated window starts 30 cm in front of its screen (was 5 cm), so it's
easy to point at apart from the screen behind it.
- No 1 s wait before a spare turns on (a disabled output never commits), and
the login splash on the spares isn't taken for floating windows.

frame-eyes, a separate project until now, becomes gaze/tracker:
- ft-eyegrab (was fe-bufprobe) copies the eye-camera frames, read-only, out of
SteamVR's eyetracking process. It runs as the system service
frametop-eyegrab.service, which gaze/tracker/install.sh installs to
/etc/frametop with sudo. It keeps only CAP_SYS_PTRACE, CAP_DAC_READ_SEARCH, and
CAP_CHOWN, and copies frames only while /dev/shm/frametop-eyes-want is fresh,
holding none of the tracker's buffers otherwise.
- ft-eyes (was fe-trackd) runs under ft-gazed in the dev container, with
build/venv's pinned numpy and OpenCV: while Eye tracker is Own tracker, or on
the probe's lease ("eyes SECONDS"). No sudo password or fe-live script at
run time any more.
- lab/ holds the research tools (ft-eyes-score, -e2e, -record, -replay,
-session) and findings.md. Recordings live outside the repo, in
~/.local/share/frametop/eyes/captures; .gitignore catches stray frame dumps.
Its socket is now @ft_eyes, its output /dev/shm/frametop-eyes-gaze, and its state
~/.local/state/frametop/gaze/eyes. On practice1 -> practice2 the whole live path
(ft-eyes-e2e) gives 1.30 deg median and 3.18 for the worst tenth, as before the
move (1.30, 3.21).

- Programs: ft-camd (the camera broker), ft-hands (the tracker), and
ft-handreplay and ft-ringplay for recordings, built by hands/build.sh
into hands/build/ with one Makefile. The first build fetches ncnn at
frame-hands' pinned tag and builds it with the same options.
- ft-camd gets its privileges from file capabilities (CAP_SYS_PTRACE,
CAP_PERFMON, CAP_DAC_READ_SEARCH) that hands/run.sh install sets with
sudo, and drops them once set up. It still works under sudo. It runs
on the host, linked statically, as frametop-camd.service. ft-hands
runs in the dev container as frametop-hands.service. Both start and
stop with SteamVR.
- Files move to /run/user/UID/frametop/ (cam-ring, hands, gestures),
not $XDG_RUNTIME_DIR, which a terminal in the Frametop desktop has
its own of. SIGUSR1 recordings go to ~/.local/share/frametop/hands.
- The calibration is read through /run/host in the container.
- Settings: HANDS_SWAP_SIDES and HANDS_CPUS in frametop.conf.
- install.sh offers hand tracking as an optional last step.
- The container gets jsoncpp-devel, glibc-static, and NumPy and OpenCV
for the Python tools.
- tools/ring.py reads the ring, and models/NOTICE credits the
Apache-2.0 models.

depth dumps to frame-hands' fh-replay on both 2026-09-29 recordings.

Frametop Input Settings' Gaze page gets two settings, saved in frametop.conf and
read again by ft-gazed when the file changes: Eye tracker (GAZE_TRACKER: SteamVR's
or our own, frame-eyes' fe-trackd) and Eye bias (GAZE_EYE: auto, left, right).
ft-gazed now combines the eyes, each calibrated on its own: SteamVR's set 2 eyes
with the probe's Left eye and Right eye calibrations, or our tracker's eyes as
they come. Without per-eye calibrations, or with --source, it keeps the older
one-source path. A pointer nudge finds its look from the raw gaze the helper
echoes back; with our tracker it goes to fe-trackd as a click.
The bias leans instead of choosing (gazecal.EyeWeights): on 306 live clicks the
eyes' errors partly cancelled, both together 0.65 deg off against 0.96 and 1.11
for either alone. Left or Right counts that eye twice; auto weights each eye by
its RMS miss at its last 20 nudges, since the calibration's fit picked the wrong
eye on SteamVR's test.

- fh-camd --with-color publishes the Arcturus colour pair (luma, half
size, 30 fps) to the ring, flagged FH_CAM_COLOR. fh-tracker records
them, and fh-replay --cams mono|color|all tracks with them, using the
module's EEPROM calibration (load_color_calibration).
tools/check_color.py checks which node is left and how the crop maps.
- Pinch detection per hand (trackd/pinch.h), published to
$XDG_RUNTIME_DIR/frame-hands/gestures (include/fh_gestures.h). It has
begin and end counters, times, the pinch point, and the begin point
for drags. tools/watch_gestures.py shows it live, and fh-replay
reports it.
- fh-replay --depth and tools/depth_report.py measure the depth without

one-camera guess, and a simulated camera loss.
- fh-tracker --swap-sides, --ring, --keep-presence, --record-only.
