Case

sendspin-server-cpp -> sendspin-cpp

Start the server first, then the client. The server loads the PCM audio derived from almost_silent.flac, the client advertises a listener and FLAC as its only supported audio format, the server connects in, uses the SDK to encode the PCM into FLAC, streams it to the client, and the matrix compares the transported FLAC header and chunk bytes as received by the client. Where the client reports the audio it decoded and the stream kept the source's sample rate and channel count, the matrix also compares its canonical PCM hash against the source clip, so a stream that arrived intact but incomplete fails.

Server

sendspin-server-cpp

Client

sendspin-cpp

Status

Passed

FLAC header and chunk bytes match exactly; decoded audio not judged against the source clip: the client reported no decoded audio

Server activation

Initial server/activate

What the sendspin-server-cpp server's own adapter recorded for its first server/activate on this connection, reported as sent. The case fails when none was sent, when its activities are not unique values from playback and pairing, or when it omits active_roles. Nothing else in it is checked against the specification: which activities and roles the matched PSK allows is not judged. A recording that cannot be read as that message is shown whole and not judged either.

Server group state

Every group/update after activation

What the sendspin-server-cpp server's own adapter recorded for each group/update it sent after its first server/activate on this connection, in order and reported as sent. The case fails when none followed, or when in any of them playback_state is not playing or stopped, or group_id or group_name is missing or not a string. How soon the first followed is not judged, because the specification says promptly and gives no bound, so one sent at any point in the case counts. Whether a change to a field produced a further message is not judged either. A recording of anything other than that message is shown whole and fails the case as a harness gap.
