Load Guidance

For Terraform v1.12+, prefer the native OCI backend for Object Storage state. Treat S3-compatible Object Storage state as deprecated fallback unless the target environment cannot use the native backend.

Use the focused sibling references first:

• oci-terraform-state-backends.md for backend and state-locking choices.
• oci-terraform-auth-matrix.md for caller/auth troubleshooting.
• oci-terraform-secrets-state.md for Vault, passwords, wallets, keys, and outputs.
• oci-terraform-import-drift.md for brownfield adoption.
• oci-terraform-module-quality.md for official-module review.
• oci-terraform-realms-regions.md for government, FIPS, realm, and endpoint checks.
• oci-terraform-zpr.md for ZPR security attributes, policy sequencing, provider support, imports, and rollout safety.
• oci-terraform-bastion.md for Bastion resources, sessions, allowlists, IAM, key-state safety, and no-public-SSH guardrails.
