# encoded sharing purely through owner_user_id (owner present => private, absent
# => shared public). resolved_visibility() must make such legacy records listable
# and accessible without rewriting persisted data, while malformed explicit
# visibility and demo/hidden semantics stay fail-closed / raw.
