- oakcodec: full crate incl. real FFmpeg decode/encode via ffmpeg-next (162 tests, 84.4% cov); new oakcodec_encoding_* metadata family (include/codec/format.h, C++ + Rust sides) - oaktask: manager/tasks/project load-save incl. OTIO via oakotio (82 tests, 86.4% cov); concurrent render loop with reorder buffer - oakplugin: M11 phase 1+2 — self-contained OFX host, GL path, ofxColour, pluginrenderer absorbed as render_driver (99 tests, 81.7% cov); instance.h additions documented - oakotio: native serde-based OTIO read/write (24 tests) - oaknode gap fill: dragger/keyframe-helper/multicam C ABI families (113/113 gtest); fixes a latent NodeInputDragger segfault - oaknode Rust skeleton: 43 built-in node type declarations - oakrender/oakstorage: declaration skeletons (implementation pending) - notes.md: gap analysis + tech-debt ledger
