APIの説明は英語のcanonical sourceを表示しています。

Derive a legacy \`MetricsMapping\` from a resolved graph's bindings. - Node host binding → \`mapping.nodes\[node.id\]\`. - Link interface binding lives on a \`NodePort\`; we attribute it to the link whose endpoint references that port, keyed \`link.id || link-${i}\` to match the rest of the server (server.ts / topologies.ts). Pure; never mutates the input.

```
deriveMappingFromGraph(graph: NetworkGraph, activeSourceIds?: ReadonlySet<string>): MetricsMapping
