Standing exception to ADR-0001 (everything is push-mirrored to Gitea). The
handbook necessarily maps the infrastructure, the backup locations and where the

Confidentiality over availability, with a local clone closing the availability
gap. Records the rejected alternatives so the question does not reopen.
