Production agents fail or succeed on control planes: signed skills, trajectory‑aware evaluation, fine‑grained permissions, payload logging, and integration discipline. Vendors (NVIDIA, Databricks, Google) are building these layers because the bottleneck is not model tool-calling but bounding and observing what those calls do.

OpenAI’s May 19, 2026 decision to join C2PA’s steering committee and embed Google’s SynthID watermark into its image outputs, combined with Google and Nvidia integrations, moves provenance from optional labeling to default media infrastructure. This raises the baseline expectation that mainstream images carry verifiable origin signals, even though it won't stop all deception.
