# Navigation (agent-native) Encode **wayfinding** in `surfaces[]` and IA notes — site identity, section, local nav, breadcrumbs — so implementers and verify subagents test orientation. ## Contract encoding Per screen: - `section`, `parent`, `breadcrumb` path - `persistent_nav`: sections, utilities, search availability - `page_title` must match link text from parent screen ## Deep-page orientation audit (verify) On random deep screen from walkthrough, actor subagent answers within 5 seconds: 1. What product/site is this? 2. What screen am I on? 3. What are major sections? 4. What are local options? 5. Where am I in hierarchy? 6. Is search available? Failures → `findings[]`. ## Design checklists 1. Persistent nav skeleton consistent across interior screens (except home variants). 2. Breadcrumbs show hierarchy, not click history. 3. Search: one box, whole product — no pre-select search type. 4. Section landing pages orient before depth. 5. Frequent tasks shortcut from home/dashboard screen spec. ## Anti-patterns - Page title ≠ link text. - Missing site identity on deep pages. - Org-chart navigation mirroring team structure. - Orphan screens with no section context in contract. ## Related - [Information Architecture](../lamina-information-architecture/SKILL.md) - [Task Analysis](../lamina-task-analysis/SKILL.md) - [Content Design](../lamina-content-design/SKILL.md)
