What is added to the response when the window becomes valid?

When a window becomes valid, a confirmation of validity is usually added in response, such as a flag or an event indicating that the data in the window meets the expected criteria. In the context of Go, this could mean adding a field or value to the response structure that signals the window has passed the check, for example, Valid: true or a similar indicator.

Example (conditional):

response := struct {
    Data  []byte
    Valid bool
}{}

// After check
response.Valid = true
