# eBdesk SiCABE — Verifikasi Phase 6 (Governance Lanjutan): OpenMetadata + Grafana
#
# Gate "kontrak governance": memastikan katalog metadata (OpenMetadata) dan
# observability (Grafana) benar-benar SIAP dipakai — termasuk saat keduanya
# EXISTING (dikelola sistem lain).
#
# Yang diperiksa:
#   A. Kontrak service : OM + OpenSearch + Grafana hidup & sehat, openmetadata-migrate
#                        selesai (exit 0)
#   B. OpenMetadata    : login (password base64) + konektor Trino & Airflow beserta
#                        konfigurasi koneksinya (termasuk kredensial service account)
#   C. Grafana         : Basic Auth, ketiga datasource ADA, dan — yang penting —
#                        tiap datasource benar-benar SEHAT (bukan sekadar terdaftar)
#   D. Dashboard       : dashboard hasil provisioning benar-benar ter-load
#   E. Temuan/mode     : catatan OIDC mati, OpenSearch password inert, dll → WARN
#
# Catatan desain (mengikuti §2.10): datasource yang "terdaftar tapi mati" adalah
# kegagalan kontrak fase ini, bukan hiburan — karena itu diperiksa sampai health API.
#
# ⚠️ Login OM yang gagal berulang dapat mengunci akun admin → gate hanya mencoba SEKALI.
#
# Exit code: 0 = semua gate lolos (WARN/SKIP boleh), 1 = ada FAIL.
#
# Usage:
#   ./scripts/verify-phase6-governance.sh
#   OPENMETADATA_URL=http://om.corp:8585 GRAFANA_URL=http://grafana.corp:3000 \
