Cartesia REST speech, batch transcription, and Ink 2 streaming transcription mirror upstream 3.0.31: CARTESIA_API_KEY, Bearer auth, Cartesia-Version default 2026-03-01, custom headers and Swift base-URL override, versioned user-agent suffix, speech/transcription aliases, /tts/bytes JSON speech, /stt multipart batch transcription, and /access-token plus duplex /stt/turns/websocket or /stt/websocket streaming. Streaming supports raw PCM/G.711 encodings, server turn detection or explicit finalization, partial/final events, raw chunks, token-redacted metadata, cancellation, and an injectable AIDuplexWebSocketTransport. Full realtime speech-session generation remains a broader protocol gap; ink-2 batch calls still fail locally before network I/O.
Factory argument requirements are defined by the public Swift factory signatures. Use Public symbols when you need the exact initializer or factory declaration.
