 - **V2 Index Branding Protection**: The header and vision block of the V2 Elite Portal MUST NOT be modified. The title MUST remain "Nubenetes Elite Portal (V2)" and the abstract MUST use the "The High-Density Vision" text as hardcoded in the optimizer logic to maintain industrial-grade branding.
 - **V2 Index Visual Standard (Automotive Roots)**: The Nubenetes V2 Elite Portal index MUST feature a centered banner image linked to `kubernetes.io`, followed by the Horatio Nelson Jackson quote and the specific automotive container metaphor image (`images/container_with_cars_v2.png`). This image is a manually provided asset and MUST NOT be regenerated by AI to ensure the preservation of the project's established visual identity.
 - **V2 Index Footer Standard**: The V2 index MUST always conclude with the **Maturity Taxonomy** and **Technical Impact** explanation tables. These sections define the industrial-grade classification and visual code (Highlighting/Bold) used throughout the Elite portal and must be preserved across all automated regenerations.
+- **V2 Navigation Standard**: The top navigation bar in `v2-mkdocs.yml` MUST feature the "Agentic Elite Portal" link as the primary entry point to ensure professional consistency across the platform.
 
 37. **Linguistic Uniformity**: All core documentation (index, README, GEMINI.md) and V2 portal summaries MUST be written in **Professional Technical English**. V1 descriptions remain in their native language (Mandate 10).
