Across realms

From the venue, into your pocket.

The experience starts in the venue and crosses into the digital realm at the close. Guests carry it home as a playlist, an iconic selfie, and an archived voice contribution — all of it kicked off by a single realm.transition event the runtime emits when the handoff fires.

// the decompression-to-companion handoff — physical realm hands off to digital
state decompression {
  intent: "Give the experience time to settle, then hand off to the companion"

  on decompression.complete -> souvenir_handoff {
    realm.transition: physical -> digital
    do: companion.deliver(template: "playlist")
    do: companion.deliver(template: "iconic_selfie")
    do: companion.archive(template: "voice_contribution")
  }

The signature moment

The reveal.

At the emotional peak of the underground, two characters appear as projected presences on a hologram in the centre of the room — among the audience. A silent recognition across the room: you're the one I've been hearing.

// safety block — halts the hologram cue if the room isn’t armed
safety {
  hologram_reveal_safety {
    when:        "presence_level.value > 0.9 and not property(\"hologram_reveal_armed\")"
    ensure:      "halt_pipeline(\"hologram_reveal_pipeline\")"
    response:    stop
    on_recovery: ["notify(template: \"hologram_reveal_restored\", channel: \"operator\")"]
  }

How OpenXP runs it

Three layers. One immutable blueprint.

// the experience header — sets the default realm
experience "Hip-Hop Immersive" {
  spec: "openxp/1.0"
  realm: physical    // venue-led, with an augmented companion at the close
  ...
}

// a slice of the WonderRoom CAVE — first light rises through wonder
journey "wonder_room" {
