Compiler hygiene (all platforms): - Silence warnings across the tree: missing override, -Wreorder ctor init, -Wshadow, -Wsign-compare, missing switch cases, unused functions/captures, Qt 6.11 deprecations (QMouseEvent/QDropEvent accessors, qAsConst, Q_FOREACH over non-shared containers, AA_UseHighDpiPixmaps) and the .bak/ backup tree removal. - Fix regressions from the cleanup: missing clip decls in capi/timeline.cpp, plugin.cpp rename fallout, panel setFocus ambiguity, QGraphicsItem::pos vs event->position(), duplicate k_push_button case, boolean test variable. Windows: - Qt portability: CommandLineParser is_set/add_option, QTimeZone systemTimeZone (QTimeZone::LocalTime is 6.11-only), k_progress_* enum. - Linking: stop adding oakengine to OLIVE_LIBRARIES (import lib plus oakengine-obj caused multiple definitions); add OAKENGINE_STATIC so internal consumers no longer reference __imp_* stubs. - oakengine.ver: export olive::Renderer typeinfo so liboakgl.so can be dlopened (Linux), DynamicRenderer no longer dlcloses backend libraries (crash in RenderManager's dtor calling into unmapped memory). - OTIO runtime: copy DLLs next to every binary on Windows instead of relying on PATH (0xc0000135 in gtest discovery). - Headless GL: the runner only has GDI OpenGL 1.1, killing every render worker. Deploy Mesa llvmpipe as opengl32sw.dll (Qt's software-GL channel) with QT_OPENGL=software, and let QT_OPENGL override the AA_UseDesktopOpenGL default. ExportTask fails fast after 8 consecutive undelivered frames instead of segfaulting or grinding forever; FFmpegEncoder::write_frame tolerates null frames. - Tests: GetTempPathA+PID temp dirs, GetLongPathNameA for 8.3 names, forward-slash normalization when comparing project filenames. Linux: - Install libshaderc-dev so oakvulkan compiles GLSL (Vulkan tests). - Accept UNORM floor-or-round (63/64) in the blit ping-pong test. - Skip MainWindow construction test on the offscreen QPA (cannot paint QOpenGLWidget). Also: oak_cli_transcode gets a 300s ctest timeout, worker logs GL context version and LoadGraph/render_frame stages, and docs/plans/eliminate-event-bridge-issues.md (English translation).
