0010. HCP Terraform for Terraform state

Status

Accepted. Date: 2026-11-04.

Context

The same app must go to production from one Terraform stack, and state must be remote and locked.

Decision

Terraform state is stored in HCP Terraform’s free tier. Modules stay OpenTofu-compatible.

Consequences

State is remote and locked on HCP Terraform’s free tier. We depend on that tier’s limits and terms.
