Boot → beep → user speaks → server VAD ends turn → assistant audio plays back → exit 0. No wakeword, no loop, no state machine. Splits Test 4 into 4a (this spec) and 4b (wakeword + loop + 16↔24 kHz coexistence, future). 4a debugs the OpenAI Realtime surface — auth, WS handshake, session.update payload, server VAD, base64 audio, streaming- length output-stream cleanup — in isolation from 4b's harder concurrency.
