Case

sendspin-server-cpp -> sendspin-dotnet

Start the server first, then the client. The client connects, advertises PCM then FLAC, and the server starts streaming the higher-priority PCM format. The client then sends a client/state whose player format prefers the FLAC entry. The matrix verifies the server received that preference in client/state and the client observed a new stream/start in the FLAC format.

Server

sendspin-server-cpp

Client

sendspin-dotnet

Status

Failed

Server received no player format preference in client/state (roles/player/v1.md, client/state player object `format`)

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.
