Repeat test-player builds no longer assign a fresh GUID to the PerformanceTestRunInfo.json/PerformanceTestRunSettings.json assets on every build. Previously, deleting these assets' .meta files as part of post-build cleanup caused Unity to assign a new GUID on the next build, which the data pipeline treated as a change and triggered a full asset rebuild even when nothing else changed. The .meta files are now cached in Library/ between builds and restored before the assets are rewritten, scoped to builds with test assemblies.
