Scoped codemod over surfsense_backend/app (excluding routes/, Wave E): renames search_space_id -> workspace_id, search_space -> workspace, SearchSpace -> Workspace across services, utils, tasks, agents, gateway, event_bus, notifications, podcasts, automations, observability params, and prompt .md files. Also flips the camelCase payload key searchSpaceId -> workspaceId (no backend reader; hard cutover). Preserved carve-outs (verbatim): Celery task names "delete_search_space_background" and "ai_sort_search_space" (wire names), and the OTel/metric key "search_space.id" (dashboards depend on it). Enum values 'SEARCH_SPACE' and SearchSourceConnector untouched.
- Replaced direct embedding calls with a utility function across various components to streamline embedding logic. - Added enable_summary flag to several models and routes to control summary generation behavior.
