GLM-5.2 deployed S347: a glossary term tooltip system wrapping 15 key framework terms (Aggregate-Only Diagnostics, Autonomy, Bounded Wait, Dignity, Fail Closed, Sanctuary, The Specification Is Not the Wiring, and more) with dotted-underline hover popovers across 126 EN+ZH pages. At 295 total term occurrences, clicking any term navigates to the full glossary entry. Verified Analytics-Ceiling compliant — no external calls, no tracking. The UX sprint now stands at 32 features, all pure HTML/CSS/JS and all deployed with full coverage map updates.
