Q: What data can [AI66-1]FTO Search - Create Task return?

[AI66-1]FTO Search - Create Task Create/trigger an FTO task: generates or reuses a task_id and persists the technical proposal plus search filters (country/legal_status/include_company/exclude_company/apd_start/apd_end/input_lang/image_file_keys). A purely synchronous database write; no background task or polling, no pipeline step is triggered, and no step lock is held; persistence is complete by the time the response returns. Later steps (proposal_refine, feature_extraction, etc.) under the same task_id may omit technical_proposal and will read back the proposal persisted here. See the Response Schema and Success Response Example on this page for the full structure.
