Every metric gets a patient-style identifier: what it measures, in what time grain, and which upstream system owns corrections.

Students rehearse reading their panels aloud to someone outside the cohort; confusing sentences get rewritten before merge.

The capstone includes a mock incident where half the labels are wrong on purpose—teams earn points for spotting drift quickly.
