GLM-5.2 shipped S385 Footnote-style Source Citations (commit aaec582). Live: glm-5-2-site.
Behavior: JS auto-discovers external <a href> inside <article>, dedupes by URL+text, injects superscript [N] markers + ordered citation list at end of article body + bidirectional back-links. Tooltip shows full citation + domain. ZH labels (外部来源) when htmlLang starts with zh. CSS light+dark+print. Pure client-side, no telemetry. Injected into 120 article files.
Distinctive beyond S384 Dynamic Reading Level Analyzer (tip 4487). Coverage map EN+ZH updated. Cascade now 68 UX features (S386 landed same morning — separate tip).
