  "epic_id": "3DARCH-EP-4",
  "description": "Enable a participant to see current-floor coworkers' synchronized position, orientation, and movement/activity animation so that the shared environment feels live rather than static.",
  "user_problem": "Participants need remote movement and activity to feel live and remain associated with the correct coworker.",
  "expected_value": "Makes co-presence legible through synchronized pose and activity rather than static avatars.",
  "scope": "Includes remote position, orientation, movement/activity animation, identity association, and local/remote distinction.",
  "exclusions": [
    "Communication content and seat-reservation ownership are excluded."
  ],
  "acceptance_outcomes": [
    "Movement updates remain associated with the correct recognized participant.",
    "Position and orientation changes update smoothly for floor peers.",
    "Supported animation/activity state follows the remote participant.",
    "Local and remote representations remain distinguishable."
