- app/ no longer includes engine C++ headers nor holds engine C++ types: engine access goes through the oakengine C ABI plus C++ wrappers (oakutil/oaknode.h, oakutil/oakvideo.h) and app-local mirror types (tooltypes, trackreferencehandle, timelinecommonapp, keyframetypes, subtitleapp, serializedlayoutinfoapp, nodevaluehandle, sliderdisplaytypeapp) - engine: new C ABI functions for block/track/clip/transition navigation and predicates, links, caches, waveform/playback, disk folder, sequence_track_list, node_free, footage_is_valid, block_get_track, get_brush; loadotio/saveotio ported to the current engine API - OTIO is now a required dependency: CI and CD build it on every platform, FindOpenTimelineIO fixed for OTIO 0.16/0.19 (the old deps include requirement silently disabled OTIO everywhere), runtime libraries are bundled into packages and copied next to macOS binaries (oak_copy_otio_runtime) - fix ProjectViewModel drag&drop mime read/write size mismatch (segfault) - unify color label naming (k_olive -> "Oak") in the app-side mirror - docs: OTIO required, FFmpeg minimum corrected to 6.0 (en/zh) - gtest suite: 1925 passed, 0 failed
