	The keystone for the stage dock. Proves Fork B on the real target (Mesa crocus, HD 4400): a toplevel's pixels, rendered by the wlr GLES2 renderer into a LINEAR ARGB8888 dmabuf, import as an EGLImage -> sampled GL texture in the sibling RMLUi GLES 3.2 context (the slice-3 bridge run in reverse) and composite into an <img src="unbox-preview://N"> inside a ui surface — upright, color-correct. Public surface (ui.hpp): class Preview (source_uri/source_width/source_height/ refresh) + UiSubstrate::create_preview(wlr_scene_tree*) -> unique_ptr<Preview> (nullptr if no GL path; never throws). Kernel-suite probes: ui_preview_import_is_dmabuf, ui_pixel(x,y). Clean four-resource teardown (URI reg, GL texture, EGLImage, dmabuf); refresh-after-source-destruction is UB (consumer drops Preview on unmap). kernel 42 cases/150 assertions green on build + build-asan (asan clean, no new suppressions). Edits confined to packages/kernel/.
2026-06-12	Slice 3: THE SPIKE — RMLUi→wlr_scene bridge lands, GO	Adam Malczewski
	Plan A verified on hardware (HD 4400/crocus): RMLUi renders into a GLES 3.2 sibling-context FBO backed by a dmabuf wlr_buffer (wlr_allocator + EGLImage import), composited as a wlr_scene_buffer with per-frame damage. Plan B (glReadPixels→shm) implemented and verified as runtime fallback; auto-engages when any Plan-A precondition fails. Plan C not needed. - Hello-world RML doc: text, data-bound frame counter, pointer input proof (hover/:active) — verified upright on screen via screenshot after fixing the classic FBO Y-flip (buffer-level V-flip keeps display == document coords for input); position-aware orientation guard added. - Temporary spike surface: Options::ui_spike + frame-count/orientation probes, host-bin --ui-spike flag; replaced by the real ui substrate contract in slice 4+. - kernel suite 6 cases / 416 assertions green; ASan/UBSan clean in our code (Mesa leak noise + 2 benign UBSan downcast reports inside vendored RMLUi are known); idle RSS ≈83 MiB. - Deferred (notes/plan.md §7): glFinish→EGL fence + swapchain; dmabuf render-format negotiation (private API in wlroots 0.20).
