The mistakes were made, fixed, and shipped past — before you got here.
Reconnects replay from the last offset. No silent gaps.
Presence is debounced — three open tabs never flicker online/offline.
WebRTC falls back to TURN relay when peer-to-peer fails.
Fan-out to thousands stays ordered per channel, never blocks on slow consumers.
Every other block already trusts the same user who joins a channel — no identity translation. New message → CRM activity logged → unread badge updates on every device. Zero glue code.
