2026-06-13Slice 10 b1: ext-xdg-shell Toplevel minimize mechanismAdam Malczewski
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/.
2026-06-13Slice 5b: config-driven keybindings — Super→fuzzel, Alt+Tab; kernel ↵Adam Malczewski
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.
2026-06-13Slice 5: real ui substrate + unified input routing + touch-mode; spike retiredAdam Malczewski
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.
2026-06-12Slice 4: extension host + typed bus; xdg-shell/layer-shell extracted to core ↵Adam Malczewski
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.
