Token stream demo

Offline demo of streaming deck into the hub.

End-to-end flow:

1. services/token-stream-demo (Tish) connects to the gateway as actor stream-demo.
2. For each cycle it sends deck.stream_chunk (single characters) so the Co-DJ panel shows a live “token” preview.
3. Then it sends deck.block with asap: true so the patch applies immediately (no perf-step queue).
4. You Play in the app to hear WsKick / WsHat / WsBass on channel ids wsdemo_k1 / wsdemo_h1 / wsdemo_b1 (the demo cycles rotating kick, hat, and bass variations).

Run

# Terminal A
npm run gateway                     # from repo root (Tish gateway)

# Terminal B
npm run token-demo                             # from repo root (runs Tish stream demo)

Open the app (e.g. npm run serve → http://localhost:3456), go to Co-DJ, Connect (session default), click Play.

Human in the loop

• Open Song and edit steps / mix on wsdemo_k1 or wsdemo_h1, then Apply (human lane). That sets human ownership on those tracks.
• After that, the stream service no longer overwrites those tracks (lane rules in Merge.tish), but it still updates any tracks it still owns.
• Add your own tracks in Song as usual; they stay yours.
