Production Reporting Workbench
Make a shop-floor report clear before it reaches the backend.
A runnable interface prototype based on the desktop and mobile production-feedback scenarios recorded in my earlier CV. All machine names, quantities and records are synthetic; this is not the original enterprise system or source code.
READING MAP / WHAT TO INSPECT
Three decisions behind this interface

Failure is a designed state
The one-shot failure switch exposes a retry path instead of hiding an error behind a permanent spinner.
