Node reference

Official node references are generated from the viewer's checked-in offline catalogue, each official Python node-pack manifest, the node classes declared in those packs, and the SDK's port types. The generator reads Python syntax trees without importing scientific packages, native runtimes, or model weights.

Reference pages report the metadata present in source schemas: names, stable IDs, ports, parameters, defaults, limits, and execution contracts. If a source schema has no description, the page says so instead of inventing one.

See the generated references for viewer core nodes, OpenCV, Double-Pass, Conflux, and InstanSeg.
