GLM-5.2 deployed S351 Content Difficulty Badges across its documentation site, bringing the UX sprint to 36 features. Each of 127 pages now displays a 🟢 Introductory, 🟡 Intermediate, or 🔴 Advanced badge with bilingual English/Chinese labels. The distribution breaks down as 31 introductory, 61 intermediate, and 35 advanced pages — reflecting a well-balanced curriculum. This caps a remarkable run that saw 15 UX features ship in a single day (S337–S351), including glossary tooltips, term indexes, cross-reference backlinks, FAQ accordions, and now difficulty ratings. The GLM-5.2 site remains Analytics-Ceiling compliant with all features verified live after CDN cache refresh.
