Case
aiosendspin -> SendspinKit
Start the server first, then the client. The client discovers or looks up the server and initiates the WebSocket connection, the server observes controller state, receives a control command, disconnects, and the matrix verifies the recorded command.
Server
aiosendspin
Client
SendspinKit
Status
Passed
Controller command matched (next)
Server activation
Initial server/activate
What the aiosendspin 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 aiosendspin 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.
