The --jq state filter is case-sensitive and currently handles open/active in both cases but not queued/in_progress, which makes it easy to miss active sessions if the API returns those states with different casing. Consider normalizing .state once (e.g., downcasing) and comparing against a single canonical set of active states to avoid this inconsistency.
