livekit-agents/livekit/agents/inference/stt.pyagents/src/inference/stt.ts. Ported theCartesiaOptionstype additions and updated comments as TypeScript interface fields/JSDoc.No source tests were added or modified in PR #6597, so there were no tests to port.

Original PR description
Companion to #6594 (which exposed these on the direct plugin): the Inference gateway already accepts and validates Cartesia's turn-detection tuning params via
extra_kwargs— they're just missing from theCartesiaOptionsTypedDict, so users can't discover them.Verified live against the gateway today:
extra_kwargs={"turn_start_threshold": 0.6}oncartesia/ink-2→ session created and runs normally.extra_kwargs={"turn_start_threshold": 2.0}→ session creation fails withcartesiaturns: extra settings validation failed: turn_start_threshold must be <= 0.9, got 2— i.e. the gateway's cartesia-turns adapter knows these params and enforces Cartesia's documented ranges.This PR only adds the keys to the TypedDict (typing/discoverability —
extra_kwargsalready passes them through verbatim) and annotates the two existing keys as ink-whisper-only, per Cartesia's API reference. Ranges/defaults from https://docs.cartesia.ai/api-reference/stt/turns/websocket.Verified with
ruff check/ruff format.🤖 Generated with Claude Code
