Realtime substrate
The chat system is documented on GetStream, with Adhoc workers and Command Bus paths around platform behavior.
Chat
Messenger, not a dead end.
Adhoc chat is the conversation surface for people, Poly, approvals, attachments, and notification-driven workflows.
Attachments and cards
Current attachment patterns include approval cards, confirmation cards, TTS audio, and media. Capsule rendering extends richer shared content.
Notifications
Chat sits beside in-app notifications, push, email-related workflows, confirmations, and voice surfaces.
Privacy honesty
Provider and processor boundaries matter; the docs do not promise end-to-end encrypted chat at launch.
