When a ``CreatedEvent`` is returned as part of a transaction tree or ledger-effects transaction, this will include all the parties specified in the ``TransactionFilter`` that are informees of the event. If served as part of a ACS delta transaction those will be limited to all parties specified in the ``TransactionFilter`` that are stakeholders of the contract (i.e. either signatories or observers). If the ``CreatedEvent`` is returned as part of an AssignedEvent, ActiveContract or IncompleteUnassigned (so the event is related to an assignment or unassignment): this will include all parties of the ``TransactionFilter`` that are stakeholders of the contract. The behavior of reading create events visible to parties not hosted on the participant node serving the Ledger API is undefined. Concretely, there is neither a guarantee that the participant node will serve all their create events on the ACS stream, nor is there a guarantee that matching archive events are delivered for such create events. For most clients this is not a problem, as they only read events for parties that are hosted on the participant node. If you need to read events for parties that may not be hosted at all times on the participant node, subscribe to the ``TopologyEvent``s for that party by setting a corresponding ``UpdateFormat``. Using these events, query the ACS as-of an offset where the party is hosted on the participant node, and ignore create events at offsets where the party is not hosted on the participant node.
