Every part works, but nothing happens. Load the scene and you see a lit table with a deck, a betting engine, three opponents who each play their own way, a HUD, and a keyboard. They all sit still. No deal fires. The flop never turns. Nobody asks for the showdown. Every component but one is wired to the bus. They are all waiting for someone to say go.

PokerTableDirector is that missing piece. It imports its siblings only to read their Event constants (and PokerBetting's setStrategies seam). Every message between components travels on the bus. The director decides when things happen, not how they happen.

Add the Match entity to the scene

Add one entity, and the scene is complete:

"Match": {
  "components": {
    "PokerTableDirector": {
      "variant": "texasHoldem",
      "startingStack": 500,
      "delayBetweenHands": 4,
      "strategyNames": ["Randy", "Bill", "Cali"]
    }
  }
}

Now src/scenes/poker.json matches the real example.scene.json exactly. That is 13 entities and 18 component placements.
