Field note
Agentic engineering is moving from one prompt to a persistent harness that manages environments, cost, review, release, and maintenance.
New Runtime reading: The output metric is shifting from model calls to accepted work: merged changes, shipped artifacts, and maintained systems, with review burden and vendor claims kept visible.
Evidence boundary: this item uses the listed public sources and keeps vendor, author, or reporter claims attributed. The queued page is an editorial synthesis, not an independent validation of every reported metric.
