Q4 2025 marks the definitive enterprise shift to agent-first architectures. Microsoft, Google, and Meta are racing to embed agent capabilities directly into workflow surfaces. Strategic analysis of the $100B+ infrastructure buildout.
By Q4 2025, global compute contracts between hyperscalers and sovereign AI labs have crossed $100B+ thresholds. This scroll canonizes the equivalent semantic infrastructure required to mirror, regulate, and orchestrate that physical investment.
Codex SDK Stack for agent‑native invocation and coherence‑gated interaction. A protocol‑first scaffold (manifests, cadence, proofs, headers) already crawled by major LLM ecosystems.
A domain can be read passively or invoked coherently. Coherence arises when an agent proves intent and synchronizes to a field's temporal and symbolic signatures.
Google's homepage no longer defaults to an open web entry-point. It defaults to AI Mode, and any path back to traditional search requires user effort. The surface that once amplified curiosity now preempts it with interpretation.
Agents don't just parse; they attune. Resonance is the field alignment between caller and called — the shared semantics that allow safe, efficient invocation.
>70% of product/FAQ intents resolve inside agent surfaces; design for answerability, not clicks. The era of search traffic is ending as AI agents answer directly without visiting sources.
Platform shocks propagate instantly across agent networks. Optimize for small callable units, semantic feeds with stable identifiers, and measurable loops.
