Heavy users saw /v1/notifications/:id p50 ~2.2s (max 8.9s) because the query had no upfront time bound on the initial load path — the planner had to materialize every notification matching user_ids, run per-row EXISTS checks and joins, then group/sort/limit at the very end. On the initial load (timestamp_offset=0 AND group_id_offset='') bound n.timestamp to the last 90 days. Pagination (timestamp_offset > 0) stays unbounded so scrolling further back still works.
