Description

Graph — the assembly stage that takes Nodes and turns them into a runnable Run.

Graph is the central concept of the framework. It collects Nodes and reusable Graph fragments, validates them against built-in contracts, compiles them into a deterministic GStreamer pipeline string, instantiates the pipeline, negotiates caps between adjacent elements, and returns a Run handle for push/pull execution. Model is internally a Graph wrapper: the same composition, validation, and runtime machinery powers Model underneath. New users typically use Model::run(); advanced users compose their own Graphs with graph.add(model) plus extra Nodes for input sources, custom processing, side branches, or RTSP server output.
