Turns "23 shots to go" into "you are not going to make it". One card per episode from EpisodeDueDate (or the project's own date on a standard show): days left, the episode's shots by where they actually are, and the only comparison that matters - shots per day still needed against shots per day the studio managed over the last week. A shot counts as delivered when it appears in a DeliveryItem inside a DELIVERED EXR_DELIVERY package. Shot.status is deliberately not the measure: it says where the work is, not whether the client has the frames, and a MOV_REVIEW package ships nothing. The pace arithmetic is a pure function so the sentence a producer acts on is testable: a rate that only just lands on the due date reports as "no slack" rather than fine, and a week with no deliveries reports as stalled instead of projecting infinity.
