Overview

A node in the group tree for an authority. The tree represents the organisational hierarchy. Each group declares which subsystems (signage, events, parking, ...) it participates in via the subsystems text array; subsystem-scoped permission queries are filtered against that array. A single root per authority is enforced by a partial unique index on (authority_id) WHERE parent_id IS NULL.
