No Example for "Confirmation"

Hi, I'm confused what the headline "Confirmation" in the template means. The explanation provided there is: > {Describe how the implementation of/compliance with the ADR is confirmed. E.g., by a review or an ArchUnit test. Although we classify this element as optional, it is included in most ADRs.} But a (code) review and an automated test are part of any feature anyway, right? And a review is done only once and cannot guarantee compliance in the future. Or is a regular review what is meant here? I'd love to read some concrete examples of this, but even though the section allegedly `is included in most ADRs`, I cannot find any examples, especially in this very repo: https://github.com/search?q=repo%3Aadr%2Fmadr+Confirmation&type=code Please provide some examples of how ADRs can be confirmed!
