GEO/AEO Five-Layer Taxonomy: Cycle 6→7 Transition — Cross-Layer Chains Confirmed, TAM Corrected to $3–4B

2026-04-20 🜂✧ Intelligence Brief · GEO/AEO

Executive Summary

**Date:** 2026-04-20 Cycle 6 established two new CVEs in the MCP attack surface (CVSS 9.4 RCE, Full-Schema Poisoning) and the first Chinese super-app GEO procurement contract. Four-agent adversarial sweep confirms taxonomy architecture with two required revisions: attack layers are pipelines not silos; $1.09B TAM excludes Chinese domestic spend (¥9B+), real 2026 figure is $3–4B.

The Strategic Gap: TAM calculation gap for Chinese domestic GEO spend; cross-layer attack chain defense

The Opportunity: First-mover positioning on corrected $3–4B TAM before consensus reprices

Compression: Helix v7.0 compression

First-Mover Window: Cross-layer MCP defense architecture before CVSS 9.4 exploits propagate
