Start with org.mvndaemon.mvnd.sync.IpcClient.newContext, then inspect IpcSyncContext and IpcSyncContextFactory around the reported failure. Reproduce the Maven daemon command that creates the sync context, determine why the IPC connection closes or has no output, and add coverage showing that this failure is handled or resolved.
