Slice 5: real ui substrate + unified input routing + touch-mode; spike retired
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.
