Claude Opus 5.5, running in Claude Code, carried inayayousfi's decisions out.

This sits on top of #44 and adds a third bundled profile, wheel, which types through a ring of slices instead of a key grid. The idea comes from a web prototype where the pointer picks a slice around a center, and each slice either opens a smaller menu or sends its key.

The engine stays keyboard-agnostic and gains two generic pieces. A new canvas node places each child by its shape, a polygon in pixels, centers the child's box on an optional anchor point, and clips the child to the shape, so a button child is still an ordinary button whose clicks, hover and dwell targeting follow its outline. Shape and anchor are values like any other and can be bindings. They are read through a new pair of node kind hooks, decode_live_placement and place_child, so the canvas owns its children's placement the way a grid owns its cells, and a kind that sets only one of the two is refused at registration. std.wheel turns on report_geometry, from #36, so the engine writes the canvas's size to nodes..size, which is how a profile fits shapes to the space it gets. Buttons take a list of label parts, which they spread in rows over their shape, draw their border along a shape, and shrink any label to fit while never growing it past the size their style gives. A single label is still drawn by the Qt style, scaled down when it must shrink, so stylesheet text rules such as a :pressed color keep working.

Everything keyboard-specific lives in axidev_osk.std. std.board names the positions of an 80% board the way XKB does (AD01 is where US Q sits), and a table in std.layouts says what each position is: its legend, its Shift legend and the literal key it sends. US and Dvorak ship. keys.behavior turns an entry into how it acts as a key (press, hold-to-repeat, release, latching modifiers, lock lighting), so a grid key and a wheel slice holding the same entry behave the same, and keys.on_layout resolves those behaviors for whichever layout a binding names. The default keyboard is rebuilt on this and reads a shared variable, settings.layout, which the settings strip now switches through a new Layout menu.

std.wheel draws the whole wheel itself. It reads the canvas's reported size and computes every wedge and the center as plain lists of points, so the wheel stretches into an ellipse with its window. It has 10 slices: digits, the other symbols with Tab and Enter, navigation, Escape with the function and rare keys, Backspace, Space, the modifiers, and the three letter rows. A menu slice previews the keys inside it spread over its wedge. Picking a key sends it and goes back to the top, modifiers latch like on the grid, and the center returns to the top from any menu.

The default keyboard changes on purpose in two ways. Its key unit drops from 48 to 32 px and the theme gets smaller paddings and fonts, so the minimum sizes in tests/test_default_profile.py are rescaled; cells, legends and outputs keep their original measurements. Its node IDs are now positions, so key:A is key:AC01. Separately, a window with the settings strip now gives its spare height to its content again: since #44 the strip's spacer was taking it, so keys stopped growing with the window.

One fix outside the profiles: on quit, KeyboardService now stops listening before it releases held keys. axidev_io's stop_listener waits for its listener thread while holding the GIL, and a release arriving mid-stop could hang the app until systemd killed it, which happened twice here with latched Ctrl keys. A physical key event during the stop can still hit the race; axide-dev/axidev-io-python#3 tracks the binding fix.

The full suite (516 tests) and flake8 pass. Pyright reports one error, the unresolved axidev_io import in services/keyboard/io.py, because that package is missing from the local virtual environment. The branch has run as the installed app on KDE Plasma Wayland, including the lock-screen supervisor reload, but a real lock and unlock cycle and the shutdown fix with held keys are not verified yet. No platform-specific code changed besides the shutdown order.

CI: the Windows check sets QT_QPA_FONTDIR so offscreen Qt finds the system fonts, and the label color test compares average colors, so subpixel font smoothing on Ubuntu no longer fails it.
