Mid-turn steering

WEDNESDAY can accept supported input during a running turn instead of forcing every correction into a brand-new conversation turn.

Endpoint

The operation is account-session protected and uses the same chat-rate-limit boundary as the live chat route.

Acceptance window

Steering is not guaranteed after a turn stops accepting input. When the transport can no longer deliver steering, the API returns 409 Conflict rather than acknowledging input that was not applied.

Cancellation

Supported steering payloads can represent durable turn cancellation. Cancellation validates the durable turn identifier and persists the cancel request before the turn is treated as cancelled.

Error behavior

• 404 — the durable turn does not exist for the account.
• 409 — the turn is no longer accepting steering.
• 422 — the cancellation form contains an invalid durable turn identifier.
• 429 — the chat rate limit is exceeded.
• 503 — steering transport, cancellation persistence, or rate-limit protection is unavailable.

Clients should surface these outcomes distinctly; a 409 is a lifecycle outcome, not a generic server failure.
