 ### Fixes
 
 - Agents/Streaming: keep assistant partial streaming active during reasoning streams, handle native `thinking_*` stream events consistently, dedupe mixed reasoning-end signals, and clear stale mutating tool errors after same-target retry success. (#20635) Thanks @obviyus.
+- iOS/Chat: use a dedicated iOS chat session key for ChatSheet routing to avoid cross-client session collisions with main-session traffic. (#21139) thanks @mbelinky.
 - iOS/Chat: auto-resync chat history after reconnect sequence gaps, clear stale pending runs, and avoid dead-end manual refresh errors after transient disconnects. (#21135) thanks @mbelinky.
 - iOS/Screen: move `WKWebView` lifecycle ownership into `ScreenWebView` coordinator and explicit attach/detach flow to reduce gesture/lifecycle crash risk (`__NSArrayM insertObject:atIndex:` paths) during screen tab updates. (#20366) Thanks @ngutman.
 - iOS/Onboarding: prevent pairing-status flicker during auto-resume by keeping resumed state transitions stable. (#20310) Thanks @mbelinky.
