The Test Outcome Analysis role is similar to the Confidence Level Arbitration role, but narrower in scope. By analyzing test outcomes (presumably by listening to EiffelTestCaseFinishedEvents) and matching them against known criteria for issue verification, this role determines when a certain issue has been verified for a particular artifact and in a particular environment (or failed verification).
None as of yet.
Test Outcome Analysis is a prime candidate for making use of an Event Analysis service, as the rules for determining whether an issue has been successfully or unsuccessfully verified can be complicated, and involve large numbers of events.
