One evening, a frantic customer ran in. “I need a receipt for an insurance claim — my entire inventory burned. The warehouse is gone. The server is gone. The only proof I have is… this.”

He placed a crumpled thermal roll in Arjun’s hand. Faded, but still legible.

Ten minutes of Bluetooth pairing, a prayer, and a system log full of errors.
