what it shows

Identifies the ContactPose transport receipt reference tied to the ZPE-XR lane.

  • The zpe-xr package and repo install surfaces are real.
  • The current ContactPose rerun proves 23.90x compression vs raw, 0.057 ms mean encode+decode latency, and 0.479 mm mean position error on the selected five-sequence lane.
  • Byte-identical replay is part of the carried transport surface.
  • The cold-start audit and release-decision packet are present and live in the repo.

what it does not claim

This surface distinguishes the current ContactPose transport receipt from broader XR runtime readiness.

  • No public release readiness.
  • No Unity or Meta runtime closure.
  • No Photon displacement claim.
  • No exact PRD-corpus closure claim.
