Device app. Acknowledges one delivery: outcome received after the whole file was downloaded, its CID, size and sha256 matched the manifest and a decoder frame was prepared without starting playback (playbackReady true); outcome failed with the failure stage otherwise. received is final and counts the work's originals as used; a failure consumes nothing. The same requestKey replays the first answer.
