47 typed options covering the full defaults file plus the OIDC and
backup-timer subsystems. The three secrets the role asserts on
(db_root_password, db_password, admin_password) are marked
required: true so ansible refuses the play with a clear error before
the validate task even runs.
Loads cleanly through ansible-core's ArgumentSpecValidator with 100%
defaults/spec coverage. Matches the spec convention used by traefik,
authentik, drawio, garage, nextcloud, opnform, coturn, talk and send.
