Run ElectronicsStoreRollUp locally using the verified startup procedure. Do not change code merely to make the application start.

Report the exact command, local address and port, successful startup evidence, relevant warnings, and how to stop the process cleanly. Confirm that the application reads all ten expected CSV files and that no source file is modified.

If startup fails, diagnose the observed error, separate evidence from inference, and propose the smallest correction. Wait for approval before changing files or installing anything.
