Make required parameters non-optional: LiveKitRunnerArguments.token,
_create_telephony_transport args. Use os.environ[] instead of
os.getenv() for required WhatsApp env vars. Guard spec/loader None
in module loading. Tighten sip_caller_phone guard in daily.py.
Use Sequence[FrameProcessor] instead of list[FrameProcessor] in Pipeline,
ServiceSwitcher, and ServiceSwitcherStrategy parameters to accept subtype
lists. Add cast() in LLMSwitcher for narrowed return types. Guard against
None in task_observer._send_to_proxy and replace hasattr with truthiness
check in task._cleanup.
Widen base strategy process_frame return types to ProcessFrameResult |
None to match actual behavior (None treated as CONTINUE). Give
UserTurnCompletionLLMServiceMixin a FrameProcessor base class so pyright
can see create_task, cancel_task, process_frame, and push_frame.
Tighten LLMMessagesAppendFrame and LLMMessagesUpdateFrame message fields
from list[dict] to list[LLMContextMessage] to match actual usage. Add
type annotations on inline message lists in IVR navigator and voicemail
detector.
Group three co-assigned fields (_start_frame_id, _start_frame_arrival_ns,
_start_wall_clock) into a single _StartFrameInfo dataclass. This makes
the "always set together" invariant structural rather than implicit, and
fixes the incorrect str | None annotation on _start_frame_id (Frame.id
is int).
Add pyrightconfig.json with basic type checking for zero-error modules
(clocks, metrics, transcriptions, frames) and enforce via CI. The
include list will expand as modules are fixed.
