Payload for the signal-open broker event.

Emitted automatically via syncSubject and forwarded to the registered IBroker adapter via onOrderOpenCommit. Discriminated by type:

• "active" — a pending signal is being opened (immediate entry or activation fill of the resting order);
• "schedule" — the resting entry order is being PLACED (scheduled signal creation).

Throw semantics (see IBrokerOrderVerdict): a plain Error / OrderTransientError rolls the open back and retries identity-stably (same signalId, attempt increments) up to CC_ORDER_OPEN_RETRY_ATTEMPTS; OrderRejectedError drops the open terminally without arming the retry.
