The CEL engine tracks changes in individual channel state and guarantees ordering of records for a given Primary, but does not guarantee ordering of records in relation to other Primaries. The exception to this record ordering occurs with meta-records which occur adjacent to the events they describe. Applicable event ordering is provided in the descriptions below.
