자체 정산 어드민에 매월 적재

# 1) 어드민 백엔드의 스케줄러가 매월 1일 트리거.
#    (자체 cron · k8s CronJob · EventBridge · 백엔드 background job 어느 쪽이든)

# 2) 4개 schema 의 data-job 을 만든다. 아래는 첫 호출 예시.
curl -s -X POST https://api.h6s.ai/api/v1/data-jobs \
  -H "Authorization: Bearer $H6S_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"providerCode":"CB_KB","schema":"bank.transactions.cb.v1","params":{"dateRangeStart":"2026-04-01","dateRangeEnd":"2026-04-30"}}'
# 같은 호출을 hometax.tax-invoices.sales.v1 / .purchase.v1 / hometax.cash-receipts.sales.v1 까지 반복 (총 4건).

# 3) 각 응답의 id 로 status 가 SUCCEEDED 될 때까지 polling.
curl -s https://api.h6s.ai/api/v1/data-jobs/$JOB_ID \
  -H "Authorization: Bearer $H6S_API_KEY"

# 4) 결과(ContractRecord 배열) 수신.
curl -s https://api.h6s.ai/api/v1/data-jobs/$JOB_ID/results \
  -H "Authorization: Bearer $H6S_API_KEY"

# 5) 받은 records 를 그대로 자체 어드민 백엔드로 POST.
#    도메인 검증·중복 제거·정산 매칭은 어드민이 책임진다.
curl -s -X POST $ADMIN_INGEST_URL \
  -H "Authorization: Bearer $ADMIN_TOKEN" \
  -H "Content-Type: application/json" \
  -d "@results.json"
