   - Supported `filters.entityTypes`: `docs`, `api`, `doctor`, `finding`, `vex_statement`, `policy_rule`, `platform_entity`.
 - Unsupported domain/entity filter values are rejected with HTTP 400; they are not silently broadened to an unfiltered query.
+- Web ambient contract:
+  - Global search emits ambient context with each unified query: `currentRoute`, `visibleEntityKeys`, `recentSearches`, `sessionId`, and optional `lastAction` (`action`, `source`, `queryHint`, `domain`, `entityKey`, `route`, `occurredAt`).
+  - Contract remains backward-compatible: if an API deployment does not yet consume `lastAction`, unknown ambient fields are ignored and base search behavior remains unchanged.
+  - UI suggestion behavior now combines obvious route defaults with one strategic non-obvious suggestion and action-aware variants (for example, policy/VEX impact and incident timeline pivots).
 - Unified index lifecycle:
   - Manual rebuild endpoint: `POST /v1/search/index/rebuild`.
   - Optional background refresh loop is available via `KnowledgeSearchOptions` (`UnifiedAutoIndexEnabled`, `UnifiedAutoIndexOnStartup`, `UnifiedIndexRefreshIntervalSeconds`).

 ### Layer 1: Query Understanding
 - Input: `UnifiedSearchRequest` (`q`, filters, ambient context, session id).
+- Ambient context envelope from Web clients includes route/session continuity fields and optional last-action metadata (`action`, `source`, `queryHint`, `domain`, `entityKey`, `route`, `occurredAt`) for follow-up ranking/refinement.
