Interpretation, not reported fact. Each point follows from a source listed below — follow the links and judge for yourself.

Reasoning token encryption standards will undergo immediate security auditing and redesign across enterprise providers. (Basis: Decrypt reported that researchers exploited a global encryption key to decode over 315,000 hidden AI model thinking blocks and extract exposed API keys.)
Enterprise focus will shift rapidly from model generation accuracy to agent containment and context isolation governance. (Basis: VentureBeat research showed 80% of enterprises cannot stop rogue agents once deployed, and 68% suffer agent failures due to missing context layers.)
