- Align local mutation dedupe keys with live event keys so the same action doesn't produce two toasts (local success + live event) - Add per-type cooldown gate (max 3 toasts per category in 10s) to suppress rapid-fire events from chatty sources - Suppress all live-event toasts for 2s after WebSocket reconnect to avoid burst floods from cached server events - TTL tuning by severity already applied externally (info=4s, success=3.5s, warn=8s, error=10s) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
