HyperDeck (TCP) ────┼─> SuperDash server (state manager) ──> WebSocket clients
vMix (HTTP XML) ────┘                                   └─> Ember+ provider
                                                      └─> TSL UMD sender

Data Types

• Device identity: id, name, type, ip, port
• Device state: play/rec/stop/offline
• Timing: timecode, update timestamps
• Metadata: filename (from device state)

Exposed Outputs

• /health JSON (device list, states, protocol status)
• WebSocket playoutStates messages (full device state list)
• Ember+ tree parameters (state, timecode, filename, connected)
• TSL UMD UDP packets (device name + tally state)
