The SSO paragraph left "whether an access policy should be bound to the
audiobookshelf application" open, which invites the next agent to relitigate
it. Frank's answer of 2026-11-03: accepted on purpose — every signer becomes a
listener with all libraries and downloads, no access policy on the application,
narrowing done per account in Settings -> Users. What that makes load-bearing is
authentik's own signup flow, now named in the same paragraph as the thing that
must stay operator-only.
