+
+### Changed
+- **SEO-Friendly URL Structure**: Reverted the entire ecosystem to use clean directory URLs (e.g., `/demos/` instead of `/demos.html`) by enabling `use_directory_urls: true` in both V1 and V2 configurations.
+- **Mandatory Path Standard**: Updated `GEMINI.md` mandates to establish root-relative paths (e.g., `/images/`) as the standard for manual HTML assets to prevent breakage across directory levels.
+- **V2 Optimization Automation**: Updated `src/v2_optimizer.py` to ensure all future automated regenerations of the V2 Elite Portal follow the clean URL and absolute path standard.
+
+### Fixed
+- **V2 Index Navigation**: Corrected all manual HTML navigation badges in the V2 index to use clean directory paths, resolving 404 errors during the SEO transition.
