Consumer Goods.

Fast-moving consumer goods generate high event volume across manufacturing, distribution and retail. Capture is $0 per event — intent, until published terms bind it — precisely so a stream that grows with volume is never a stream you stop feeding; every event carries a stamped warrantor and a graded observer.

Volume is the point, so the meter is not.

Illustrative: one pack-out shift at a co-manufacturer. The aggregation shape is the standard's; the counts are invented. $0/event is intent, until published terms bind it.

For the engineer who owns the brand's event feed.

A high-volume feed dies the month it becomes a bill that grows with volume — which is why capture is $0 per event by intent, and why the gate lands on answers, never on compute. The brand reads the co-man's chain under a grant; the party grain on each event is derived when it reads, never stamped.
