Navigation in SnS combines database-backed application navigation with local technical documentation trees where the content is still being shaped. DatState owns global navigation resolution and exposes valid sitemap items based on configured routes.

• Use database NavItems for application navigation when routes are managed by the platform.
• Use local navigation structures for temporary documentation trees until a DocState pattern is approved.
• Use NavLink for route-aware active behavior when rendering links in Razor.
• Keep active-class helpers simple and local to the state or component that owns the selection.

SnS and DataMine documentation libraries currently use different layouts. Cross-library switching should happen from deliberate outer navigation rather than inside one library layout.
