Editor-only MCP utilities for s&box. It adds model import and inspection tools, input tracing and camera helpers, and editor networking that can launch and manage owned sbox play instances. The code is C# with some Windows P/Invoke for file ownership and process/job control, plus asset pipeline glue and hotload state handling.
Unit tests for the model import pipeline. It runs a console test runner that creates temp fixtures, fakes a backend, and exercises ModelImportTransaction, OwnedAssetFile, ModelImportRequestGate, ModelImportBackendPipeline, InputTraceBuffer, and hotload and transfer paths. It exits with a nonzero code on failures.
