The prod deploy failed restoring a transitive package (Microsoft.CodeAnalysis.Workspaces.Common) with NU3008 "package integrity check failed / has changed since it was signed" — a transient corrupted download on the build host, not a code change. Wrap the backend `dotnet publish` so that on any failure it clears all NuGet caches and retries once, re-downloading the package fresh. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
