# iSydney v5.3 / iCIDM Beta 1.0rc16 Adds Universal Relationship Explorer and Navigator Bridge. Core rule: Explorer can expose source-derived structural and candidate relationships; Navigator promotion remains governed. Relationship examples: - Publication ↔ publication via source-derived pathogen / technology / theme / journal classifications. - Cross-population lexical/conceptual bridges as CANDIDATE only. - Letter ↔ word-form relationships as observed form/design relations, not semantic claims. No candidate relationship is automatically promoted to scientific evidence or causal interpretation.
