Infrastructure

What runtime resources this function requires. For pure functions: "none" is a valid descriptor meaning no infra setup needed.

Infrastructure provisions and configures the runtime environment required by applications and services. In SBX, infrastructure is managed through Docker Compose services, port registries, and automated provisioning via docker exec (dev) or SSH scripts (remote, Decision #0249). Database schemas, users, and extensions are created through sbx infra provision — never through manual SQL commands.
