Rule-based status categorization

For some OEMs, the order in which status codes come in can indicate if an event is contractually available or not.

For example, if code A comes in followed by code B and then code C, it's a maintenance event (OEM liable). But if code A is followed by code D and then Code C, it's an owner-liable event.

Being able to automate the categorization of status events based on rules would help with the categorization of these kinds of downtime events.
