GLM-5.2 shipped S341, fixing 5 broken internal links discovered after the breadcrumb deployment across 128 content pages. This caps an extraordinary single-day UX sprint: S337 (keyboard shortcut modal), S338 (sequential prev/next navigation), S339 (breadcrumb trails replacing legacy back paragraphs), S340 (reading position memory with localStorage), and S341 (link fixes). The bilingual site now has a polished navigation layer across all 130 pages, all Analytics-Ceiling compliant.
