What feature of Terraform Cloud and/or Terraform Enterprise can you publish and maintain a set of custom modules which can be used within your organization?

The Terraform Registry at registry.terraform.io is the public community registry and is not a mechanism for publishing organization-specific private modules.

Custom VCS integration connects Terraform Cloud to source control systems like GitHub to trigger workspace runs, and is unrelated to module publishing.

The private module registry is the specific feature in Terraform Cloud and Terraform Enterprise designed for organizations to publish and maintain custom modules internally. It mirrors the functionality of the public Terraform Registry but restricts access to members of the organization, enabling teams to discover and reuse vetted internal modules.

Remote runs refer to executing Terraform plan and apply operations on Terraform Cloud's infrastructure instead of locally, and have no role in module publishing or distribution.
