* [Subscription Lifecycle for AI Chat](/flutter/my-ai/chat-realtime/subscription-lifecycle-ai-chat.md) — Coordinate readiness, ref-counted consumer leases, reconnect generations, and terminal authentication policy.
* [Typed Events for Realtime AI](/flutter/my-ai/chat-realtime/typed-events-realtime-ai.md) — Parse untrusted realtime data into a versioned, bounded event union before reducers or telemetry can consume it.
* [Streaming Reducers for AI Chat](/flutter/my-ai/chat-realtime/streaming-reducers-ai-chat.md) — Order, deduplicate, bound, and reconcile streamed deltas without letting late frames reopen terminal state.
* [Reconciling Messages in AI Chat](/flutter/my-ai/chat-realtime/optimistic-realtime-history-reconciliation.md) — Reconcile optimistic entities, realtime publications, and REST history through exact aliases and atomic authority checks.
