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.

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.
Proof, not adjectives. The gateway's conformance tests pass against GS1's normative artifacts. See Who for the dimension, and What ships today for the dated ledger.
