Changed behavior: native iOS URLSessionWebSocketTask replaces SocketRocket for main app socket. Cannot execute on Linux: no xcodebuild, Swift toolchain, Apple SDK, or iOS client. Original iOS bug NOT reproduced on main. Native fix NOT verified.

Observed assistant reply: transport verification ok
Reload: persisted history displayed; fresh /ws upgrade returned 101 and negotiated permessage-deflate.
Browser offline for 2s, then online; follow-up prompt submitted and assistant replied reconnect verification ok. This does not prove a physical TCP interruption or native reconnect.

Checks: GitHub head checks inspected. Build and Typecheck, Lint, Test, all 8 server shards, Mobile Native Static Analysis and Check passed. Some deploy/native preview checks skipped; no new local or remote test suite run in this verification pass.
No tracked source changes, commits, pushes, labels, merges, closes, rebases, or force pushes.
Unverified: native iOS handshake/compression, compilation, old-binary/Android fallback, native lifecycle/background/resume, native reconnect, physical devices, release builds, T3 Connect/proxies, large frames.
