Findings: unified surface holds on tokio-postgres with the transactional property intact (in-tx NOTIFY is commit-atomic; rollback drops all); LISTEN wake beats poll 5-16x at p50 with 300/300 isolated delivery; pooled-LISTEN discard (deadpool#360) verified and pinned as our own test; postgres-notify 0.3.8 evaluated and passed over (lazy reconnect, no initial-connect script, unquoted identifier LISTENs) in favor of the ~90-line hand-rolled forwarder with test-pinned pitfalls. sqlx PgListener fallback retired unfired.
