# eBdesk SiCABE — Verifikasi Phase 2 (Storage & Catalog): MinIO/S3 + Nessie
#
# Gate "kontrak storage": memastikan object storage & Nessie benar-benar SIAP
# dipakai fase berikutnya (Trino, StarRocks, Airflow/Sling, Dremio) — termasuk
# saat memakai object storage / Nessie EXISTING (S3_ENDPOINT, NESSIE_URL).
#
# Yang diperiksa:
#   A. Object storage : endpoint terjangkau, bucket ada, tulis+baca berhasil
#   B. Nessie         : /api/v2/config, default branch, endpoint Iceberg REST <prefix>/v1/config
#                       (prefix dari NESSIE_ICEBERG_PREFIX, default /iceberg)
#   C. Version store  : database `nessie` + tabel Nessie di PostgreSQL (JDBC2)
#   D. Kontrak & antarmuka:
#       D1 (milik Phase 2)    : warehouse & endpoint S3 pada Nessie (compose) → FAIL bila salah
#       D2 (milik fase 3/4/5) : config Trino / Sling / StarRocks selaras → WARN/SKIP saja
#
# Mode --deep (opsional — menguji KONSUMEN, jadi komponennya harus sudah ada):
#   E. Trino              : baca nyata dari warehouse (SELECT count(*) FROM iceberg.bronze.orders)
#
# Prinsip gate: hanya memverifikasi kontrak yang DIMILIKI fase ini. Pemeriksaan yang
# bergantung pada runtime fase lain (mis. Trino di fase 3) tidak dijalankan kecuali --deep,
# supaya gate tidak pernah "hijau karena di-SKIP" atau salah atribusi kegagalan.
#
# Exit code: 0 = semua gate lolos (WARN/SKIP boleh), 1 = ada FAIL.
#
# Usage:
#   ./scripts/verify-phase2-storage.sh
#   ./scripts/verify-phase2-storage.sh --deep     # + uji baca via Trino (fase 3)
#   S3_ENDPOINT=https://s3.corp.internal NESSIE_URL=https://nessie.corp.internal \
