  "description": "Composition sub-shape of the umbrella usd-structure-assessment-report.schema.json. Covers the composition slice only (detailed arrays). The umbrella schema uses counts for routing; this schema provides the full arc lists for tools that need them. Casing note: this standalone sub-shape intentionally keeps camelCase keys (e.g. usedLayers, instanceablePrims, unresolvedAssetPaths, recommendedNextActions) to preserve compatibility with external tools/pipelines that consume the composition slice in isolation. The umbrella SA report is itself mixed-case (snake_case SA-domain fields alongside camelCase USD-native stage keys like rootLayer/upAxis/metersPerUnit); do not rename these keys without coordinating with those standalone consumers.",
