A validator checks a specific expectation over a limited period. Use one when your application wants to confirm that an operation worked, rather than continuously watching for a recurring problem. Detectors and validators therefore have different lifetimes.

Validators run on Observer updates until they can produce a report or are cancelled. An absence of evidence is not a successful validation.

Keep validators separate from continuing issue detectors. Ensure Observer updates run when disabling automatic updates.
