Composable Model Graph

Where Model Graph is the primitive, Composable Model Graph is where the primitives become usable: implemented transforms, a way to run a graph over data, capture a trace, evaluate it, and compare two runs.

The recurring shape is a loop: run a graph, capture the trace, evaluate it, produce feedback, and see what to improve.

That same loop underlies both interpretability (recover and measure a system) and reliability (hold its behavior steady).

It carries a small set of cross-cutting pieces, including a transfer-function primitive shared with the interpretability work, so the same object that describes a control system can describe a layer of a network.
