The GraphInput/GraphOutput cards render through the same build path
as every other node (real graph data, fixed header accents outside
both palettes), GraphOutput as a pure sink with no output ports.
UI-layer protection keeps the pair fixed: the context menu drops the
whole edit section (cut/copy/paste/duplicate/rename/delete) for
them, and delete requests naming an endpoint are narrowed at the
panel — the endpoints and the wires hanging off them always stay,
a request left with nothing is dropped whole. The engine reports the
protected set through AppEngine::protected_graph_nodes (the real
engine resolves Graph::endpoints; the mock demo graph carries its
own marked pair).
All crates take the oak-* kebab-case naming (oak-audio, oak-codec,
oak-common, oak-core, oak-ffmpeg-link, oak-node, oak-otio, oak-plugin,
oak-render, oak-storage, oak-task, oak-timeline, oak-undo), with the
lib identifiers rewritten (oakrender:: -> oak_render::, oakcore_rs:: ->
oak_core::, ...) across all 226 referencing files.
The GUI application moves from the workspace root into
crates/oak-app/: src/, build.rs (paths fixed for the new location) and
tests/ travel with it, the root Cargo.toml becomes workspace-only
([workspace] + workspace.package + profiles), and the app package
inherits the workspace version. The screenshots example becomes a
standalone crate examples/simple_player/ with its own Cargo.toml.
Every crate now inherits the single workspace version
(version.workspace = true), and the workflows' crate paths and the
build docs follow the renames.
Validated with a clean cargo check --workspace.
