-- Упрощённый UPSERT для сохранения claim с известным claim_id
-- Используется в n8n workflow: form_get (нода claimsave)
-- Дата: 2025-11-21
-- Описание: Простой INSERT/UPDATE для claim, т.к. claim_id уже известен

-- Входные параметры:
-- $1: payload_partial_json (jsonb) - данные формы с wizard_answers, wizard_plan, documents_meta
-- $2: claim_id (text) - UUID заявки

ПРИМЕРЫ ИСПОЛЬЗОВАНИЯ:

1. Вызов с wizard_answers и wizard_plan:

SELECT * FROM ... WHERE ... = (
  '{
    "session_id": "sess_xxx",
    "unified_id": "usr_xxx",
    "contact_id": "12345",
    "phone": "79262306381",
    "wizard_answers": "{\\"q1\\": \\"answer1\\"}",
    "wizard_plan": "{\\"questions\\": [...]}",
    "documents_meta": [
      {
        "field_name": "uploads[0][0]",
        "file_id": "clientright/0/file.pdf",
        "file_name": "file.pdf",
        "original_file_name": "original.pdf",
        "uploaded_at": "2025-11-21T12:00:00Z"
      }
    ]
  }'::jsonb,
  'uuid-here'::text
);

2. Вызов БЕЗ файлов (только answers):

SELECT * FROM ... WHERE ... = (
  '{
    "session_id": "sess_xxx",
    "unified_id": "usr_xxx",
    "contact_id": "12345",
    "phone": "79262306381",
    "wizard_answers": "{\\"q1\\": \\"answer1\\"}",
    "wizard_plan": null,
    "documents_meta": []
  }'::jsonb,
  'uuid-here'::text
);

РЕЗУЛЬТАТ:
{
  "claim": {
    "claim_id": "uuid",
    "claim_id_str": "uuid",
    "status_code": "draft" or "in_work",
    "unified_id": "usr_xxx",
    "contact_id": "12345",
    "phone": "79262306381",
    "session_token": "sess_xxx",
    "payload": {...}
  },
  "documents": [
    {
      "id": "uuid",
      "field_name": "uploads[0][0]",
      "file_id": "clientright/0/file.pdf",
      "file_name": "file.pdf",
      "original_file_name": "original.pdf"
    }
  ]
}
