At 5:00 AM, the tins finally came out. Marcus did another spot-check. He held the tin up to the light. It wasn’t just clean. It was quiet . The way water feels after it’s been filtered. The way air smells after a storm.

Marcus leaned against the wall. He thought about the time five years ago when a hidden fleck of old dough had survived the old machine. It had baked into a batch of rye bread, turned into a hard black rock, and a customer had cracked a tooth. The lawsuit cost the bakery thirty grand.

“That’s nothing,” Marcus muttered. But the controller didn't care about opinions. It had already triggered an automatic re-wash cycle. The conveyor belt reversed. The 5,000 tins began their journey back through the pre-wash, the detergent bath, and the rinse.
