- ValueType::Parametric; the node input carries the whole curve set as
NodeValue::Text(JSON) so undo and project serialization come for free
- translation pass builds the input with the default-curve JSON and the
dimension/range/ui-colour properties
- edits flow both ways: node input (UI) -> curves_from_json ->
set_ofx(Parametric) on the instance; plugin-side Set/Add/Delete ->
notify_instance_changed -> JSON written back to the input (undoable)
- screenshot example: gate the macOS-only offscreen capture items so
the workspace tests build on Linux/Windows
With the C ABI facade (oakengine) retired, the frozen-ABI rationale is
gone. UndoCommand now boxes a Send Command trait (new/from_closures/
multi), dropping OakUndoCommandVtable, the userdata trampolines, the
refcount shell, the handle module, and all undostack_* handle exports.
The global facade loses its raw-pointer out-params (can_undo/can_redo
return bool, command_name returns String). oaktimeline/oaknode/
oakplugin/oaktask construct commands directly via UndoCommand::new.
oakundo src is now free of unsafe; behavior (ordering, idempotence,
done flags, groups, observers, 200-row cap) is unchanged and pinned by
the rewritten tests.
Single-lib cleanup: the per-crate src/bridge/ and src/ffi.rs layers are
gone (oakundo/oakcommon/oaknode/oaktimeline/oakcodec/oakaudio/
oakrender/oaktask/oakplugin/oakstorage); cross-crate calls are plain
Rust, CHandle marshalling shrinks to the oakengine boundary, and tests
call the Rust APIs directly (pure C-ABI wrapper tests removed where
the domain layer already covers the behavior).
exporter.h family implemented: oakengine_export_render (CLI contract),
oakengine_export_render_with_params (was a stub), last_error and
progress callback; synchronous path reuses task_create_export +
start_sync. Fixes on the way: oaktask video ticket self-deadlock,
audio params dropped on the export path, codec encoder AAC slicing and
H.264 time base. Real-mp4 tests cover both entry points, progress and
the illegal-argument matrix.
Also: oakstorage session maps null project handles to None (version-
info path), configstore test double literal 3.14 -> 3.15 (clippy PI
lint), oakaudio output callback scratch buffer + env-aware P1 test,
cli media round-trip test uses a generated 16-frame clip (no more
minute-long debug runs).
