-- ============================================================================
-- SQL запрос для n8n: Сохранение первичного черновика заявки
-- ============================================================================
-- Назначение: Сохранить первичный черновик сразу после генерации wizard_plan
--             Использует session_token для связи (claim_id генерируется позже)
--
-- Параметры:
--   $1 = payload_json (jsonb) - полный payload с wizard_plan, problem_description, 
--                                AI Agent1, AI Agent13 и т.д.
--   $2 = session_token (text) - сессия пользователя
--   $3 = unified_id (text, опционально) - unified_id пользователя
--
-- Возвращает:
--   claim - объект с claim_id (UUID), session_token, status_code, payload
--
-- Использование в n8n:
--   1. PostgreSQL node
--   2. Query Type: Execute Query
--   3. Parameters: 
--      $1 = {{ JSON.stringify({...}) }}
--      $2 = {{ $('Edit Fields11').first().json.session_token }}
--      $3 = {{ $('Edit Fields10').first().json.unified_id || null }}
