/**
 * Transcribe a neural-signal buffer with a loaded BCI model and return the
 * complete text. Accepts either a `.bin` file path or a raw neural buffer.
 *
 * @param params - BCI transcription parameters.
 * @param params.modelId - The identifier of the loaded BCI model to use.
 * @param params.neuralData - Neural signal as either a file path (string) or
 *                            a binary buffer (`Uint8Array`).
 * @param params.metadata - When true, resolves to an array of transcript
 *                          segments (`{ text, startMs, endMs, append, id }`)
 *                          instead of joined text.
 * @param options - Optional RPC options including per-call profiling.
 * @returns A promise (decorated with `requestId`) resolving to the complete
 *          transcribed text, or — when `metadata` is true — the list of
 *          transcript segments in emission order. The `requestId` is
 *          reachable synchronously so callers can target this in-flight
 *          transcription with `cancel({ requestId })` before `await` resolves.

/**
 * Opens a bidirectional streaming BCI transcription session. Neural-signal
 * chunks are streamed in via `write()`, and transcription is yielded as the
 * addon's sliding window decodes successive windows.
 *
 * The returned session is single-use. Attempting to iterate a second time
 * will throw a `TranscriptionFailedError`.
 *
 * @param params - Streaming BCI transcription parameters.
 * @param params.modelId - The loaded BCI model to use.
 * @param params.metadata - When true, the session yields transcript segment
 *                          objects (`{ text, startMs, endMs, append, id }`)
 *                          instead of plain text.
 * @param params.windowTimesteps - Decode window size in timesteps.
 * @param params.hopTimesteps - How far the window advances between decodes.
 * @param params.emit - `'delta'` (default) yields only the newly-discovered
 *                       tail per window; `'full'` yields the full running
 *                       transcript each update.
 * @param options - Optional RPC options including per-call profiling.
 * @returns A session object: call `write(neuralChunk)` with a `Uint8Array`
 *          to feed neural-signal bytes, iterate with `for await (...)` to
 *          receive transcription, and `end()` to signal end of input. The
 *          session exposes `requestId` synchronously for targeted
 *          `cancel({ requestId })`.
