The day’s biggest thread wasn’t a new model launch—it was control. Governance stories shifted from “see what the system did” to “prove what it was allowed to do,” as enterprises plan for autonomous agents that move between connected and disconnected environments. One survey found 47% of respondents operate across mixed environments, with 11% running generative AI in on-premises and air-gapped setups; that combination is what makes plain audit logs feel like weak testimony. The answer on the table is verifiable enforcement: cryptographic, tamper-evident records that show an agent’s contextual authorization before it delegates actions across systems.
