 - The public API accepts signed little-endian mono PCM16 as binary frames. Use native `PCM_24KHZ` (48,000 bytes/second); `PCM_16KHZ` is also accepted and server-resampled.
 - `PUSH_TO_TALK` is the mode matching Dictate's one explicit turn. Defaults also include `partialMode: "CUMULATIVE"` and `emitAudioProgress: true`.
 - Wait for the server's `{ "sessionId": "..." }` acknowledgement before sending audio. Frames carry no headers, timestamps, sequence numbers, or semantic boundaries; approximately 80 ms pacing is guidance rather than a required frame size.
- End input with the text frame `{ "type": "endStream" }`, continue reading, require a `transcript` event with `final: true`, then accept normal close code `1000`.
+- End input with the text frame `{ "type": "endStream" }` and require a `transcript` event with `final: true`. Treat that correlated final as completion and close the connection rather than waiting for Meta's idle close, while preserving any provider failure that races with finalization.
 - Cumulative partials replace the prior hypothesis. Dictate ignores partials, turn boundaries, endpointing, and speaker events and retains only the explicit bounded final transcript.
 - `keywords` and `languageBias` are handshake-only hints. The existing coding dictionary can feed `keywords`; no free-form prompt field is documented.
 - Meta documents a 60-minute session, at most five seconds of audio backlog with approximately realtime pacing, eight concurrent streams, and 1,000 streams/hour. Dictate's own five-minute cap remains stricter.
