@v2/psyche-caption-streaming wires real-time match captions through @psyche/caption-streaming.

The bridge composes the Psyche accessibility caption engine and live caption orchestrator into one V2 session plan. It creates channel plans for in-match HUD captions, spectator mode overlays, replay transcripts, companion second-screen captions, and broadcast observer captions. @v2/iris-accessibility remains the accessibility semantics owner while Psyche owns the low-latency caption stream.

Required V2 events:

  • v2.caption-stream.match.started
  • v2.caption-stream.segment.rendered
  • v2.caption-stream.spectator.channel.updated
  • v2.caption-stream.accessibility.alerted
  • v2.caption-stream.replay.transcript.updated

The contract is presentation-only. It declares off-rollback-caption-ui-only, sets mayInfluenceRollback: false, and has no deterministic gameplay impact if captions arrive late, are corrected, or are disabled for a surface.
