A TTS request therefore occupies only its own thread during Microsoft network I/O + streaming; other clients are unaffected. Combined with early auth, a strict per-client 2 s rate limit, 5000-char cap, and voice allowlist, the blocking cost is bounded and intentional. All audio chunks are buffered before sending so that a Content-Length header can be included. The 5000-char cap bounds audio to roughly 1-5 MB, making full buffering safe. Without Content-Length the HTTP/1.0 server leaves the response open until a ~31 s timeout fires, and the browser cannot play the blob mid-stream.

If the session record has no model persisted, ``_resolve_compatible_session_model_state`` falls back to the configured default model/provider (documented in the impl report §1). - Delegates to ``_start_chat_stream_for_session`` which spawns the agent on a daemon worker thread (the drain thread NEVER blocks) and serializes on the per-session agent lock + active-stream guard, so a concurrent human ``/api/chat/start`` cannot double-start (one wins, the other gets the existing 409 "session already has an active stream").
