Is “validated” the right term? It seems this could be confused with cache validation, which is only applicable to a cached response and is generally/intuitively viewed as a client-initiated action.

Also, which response is the point of reference for validity/freshness? The proposed sentence seems to refer to a pushed response being “validated” at the time that the pushed response itself was generated. I assume we’d actually want to treat the pushed responses to be fresh at the time the response for the associated/original request was generated.

I'm good with this one.     I like the instantaneous nature of it.

Any attempt to define the ongoing validity of a resource implies that something will be checking that on the server side and overlaps with the cache control headers.
