- copy engine/node (188 files) to src/node/src, de-Qt in waves: core infra (Node/Param/Value/Variant/mathtypes), project/serializer, block/output, color, effect leaves, generator, gizmo/plugins - strip QObject/signals/slots: notifications move to the facade's oakengine_event channel, ownership becomes explicit (unique_ptr, add_keyframe/add_gizmo), sender() replaced by current_gizmo - QVariant replaced by olive::Variant, Qt math types by POD mathtypes, QXmlStreamReader/Writer by oakcommon's expat-based classes - sink VideoParams/SubtitleParams/LoopMode/ColorTransform to oakcommon (M3.5); polygon/text rasterization behind backend hooks - pure C ABI in include/node + src/node/c_api (oaknode_ prefix, OAKNODE_E_* codes, undoable variants take OakUndoCommand out-params) - fix Project::clear() root_ reset + disconnect assert, Sequence TrackList leak - 96 gtest cases green in standalone build (build-oaknode) - docs: signal/slot handling strategy + M3 implementation status
