- Toplevel::set_size(w,h): expose wlr_xdg_toplevel_set_size (async configure;
0 = client picks). Lets the window field size a client to its tile.
- Advertise xdg-decoration and force SERVER_SIDE when the RML field draws chrome
(create(prefer_server_side_decorations), wired from host-bin's
--rml-compositing) so clients drop their own CSD titlebars; classic path keeps
CSD. The mode is applied only once the xdg surface is initialized (on the
surface commit / request_mode), avoiding a wlr_xdg_surface_schedule_configure
assertion when the client creates the decoration before its initial commit.

Wave 2, additive — existing wlr_scene compositing of toplevels held intact
(the switch to surface elements is a later wave behind a flag).
- New contract: Toplevel::wl_surface() -> wlr_surface* (the root surface, ==
xdg_toplevel->base->surface, the same surface scene_tree() hosts). A borrow
with the same lifetime as the Toplevel (valid until on_toplevel_unmapped).
This is the surface ext-window-field (Wave 3) passes to the kernel's
UiSubstrate::create_surface_element(); the kernel then manages the
subsurface/popup tree itself, so no popup/subsurface handles are exposed.
ABI-additive: ext-keybindings/ext-stage-dock/host-bin rebuild + link unchanged.
- Fixed the ext-xdg-shell-client teardown SIGABRT. Diagnosed (not assumed): the
abort is NOT pre-existing on baseline (seed 12e5016 passes) — it is the kernel
Wave-1 surface-capture TEST SEAM attaching a commit Listener to every client
wl_surface and only detaching at Server teardown, so a client destroying a
surface mid-session trips wlroots' wl_list_empty(commit.listener_list)
assertion. Fixed in-unit via teardown order (unmap via null-buffer commit; let
the Server destructor reap the surface after detaching its seam). Filed a
kernel change-request for the real fix (RAII per-surface destroy listener),
which will also cure ext-stage-dock-glue.
ext-xdg-shell suite 2/2 green in build + build-asan, no SIGABRT, no unbox::
leak/UB. wl_surface() covered (non-null, == root surface, round-trips through
scene_tree_for()).

Neutral compositor-side mechanism the stage dock drives to minimize a window
(the "minimized" state/policy stays in ext-stage-dock). Adds to Toplevel:
geometry() -> wlr_box (size the preview + restore position), scene_tree() ->
wlr_scene_tree* (feed UiSubstrate::create_preview + the node hide/show toggles),
and hide()/show() — disable/enable the scene node so the client stops compositing
and frame callbacks WITHOUT unmapping (no on_toplevel_unmapped, no focus change),
idempotent. Verified against wlroots 0.20 that a disabled node quiesces frames.
A real in-process wayland client test (test_minimize.cpp) drives it on the
headless backend.
ext-xdg-shell suite green on build + build-asan. Edits confined to packages/ext-xdg-shell/.

exports WAYLAND_DISPLAY
ext-keybindings (new core ext) reads unbox.toml: tap-Super spawns fuzzel,
Alt+Tab/Alt+Shift+Tab rotate focus across all toplevels, plus Alt+F1 and
Ctrl+Alt+Backspace (quit). ext-xdg-shell's hardcoded keybinds removed
(migrated to the toml).
Kernel setenv()s WAYLAND_DISPLAY at startup so extension-spawned clients
connect to unbox, not the launching session — fixes fuzzel "no monitors"
on the real seat.
build + build-asan green: third-party Mesa/EGL/DRM + vendored-RmlUi sanitizer
noise suppressed (suppressions/), our code stays leak-checked; a real
libwayland leak in the layer-shell client test fixed.
Harness: spawn-env + sanitizer-noise rules, diagnose-real-seat skill,
GLOSSARY keybinding/action/tap-binding. Real-seat verified on the CF-AX3.

The ui substrate is now the extension-facing contract (unbox/kernel/ui.hpp):
Host::ui() -> UiSubstrate::create_surface(spec) -> UiSurface with typed
scalar bindings (int/double/bool/string getters), data-event callbacks
(error-isolated per extension), dirty(), geometry/visibility — RMLUi and
GL stay kernel-private. Production sync: glFinish replaced by
EGL_KHR_fence_sync + 2-deep wlr_swapchain. ui_spike retired (orientation
guard + dirty-cycle coverage live on as substrate tests).
Input: ONE kernel routing path feeds pointer AND touch into ui surfaces
with consume-or-pass semantics and implicit-grab ownership (the consumer
of a press owns the matching release; per touch point too) — fixes
drag-release-over-ui sticking. touch-mode: state machine + debounce +
on_touch_mode_changed notification, NO visual scaling (user decision
after hardware hands-on; dp-ratio stays 1.0; see plan §2).
ext-xdg-shell: GrabMachine generalized to pointer-OR-touch interaction
source (touch titlebar drag works; originating-point pinning); fixed the
seat implicit-grab leak (suppressed release after forwarded press
swallowed all later touch-downs — pointer/touch alternation doctested);
factory renamed create(). ext-layer-shell: on_demand keyboard
interactivity via scene hit resolution. host-bin: --ui-demo extension
(temporary acceptance demo on the public contract, dies in slice 6).
User hands-on verified: same surface by mouse and finger, tap counter,
touch-mode neutrality, no click-through, drag alternation, fuzzel
on_demand. 113 doctest cases green, ASan/UBSan clean (our code), idle
RSS ≈78 MiB. Harness: UX-feel hands-on lesson (ORCHESTRATOR §2.6),
nested-run pkill/setsid notes, touch-mode glossary redefinition.

extensions
The kernel now names NO concrete feature. It owns: the extension host
(install/topological activate, missing-dep/cycle = startup error), the
typed Event/Filter bus (error-isolated: a throwing extension is disabled,
never the session; RAII Subscriptions), the Host API (per-extension
facade: borrows, scene layers, event catalogue, typed services), the
public RAII Listener, and a typed surface→scene-tree registry
(Host::host_surface/scene_tree_for) that replaced the untyped
wlr_surface.data convention both extensions flagged.
- ext-xdg-shell (core): toplevel/popup lifecycle, focus-on-map,
click/tap-to-focus, pointer/touch routing incl. button+axis (the
kernel only moves the cursor and emits — a contract-doc lie caught by
user hands-on), interactive move/resize via pure GrabMachine (fixes
the request-arrives-after-release race: grab requires request ∧
button-down, release always ends it), Alt+F1 cycle,
Ctrl+Alt+Backspace terminate (labwc's default A-Escape=Exit killed
the dev session once — never again; see nested-run skill).
- ext-layer-shell (core): wlr-layer-shell v1 (proto v5) for external
clients; pure doctest-hard arrangement core; fuzzel verified visually
nested (fix: seed outputs from output_layout at activate — events-only
tracking missed pre-activation outputs; plus a scene-node double-free).
- First protocol codegen: vendored wlr-layer-shell XML + wayland-scanner
server-header propagated through kernel_dep; wlr.hpp grew a
namespace→_namespace keyword fix for the generated header.
- Glossary: 'scene layer' (user-approved). New rules earned:
parallel-wave-builds, contract-docs.
- User hands-on verified: typing, click-to-focus, drag-select, scroll,
titlebar drag-move (slow + flick), Alt+F1, fuzzel + arrows, touch tap,
Ctrl+Alt+Backspace. 68 doctest cases green, ASan/UBSan clean (our
code), idle RSS ≈73 MiB.
