  "description": "Enable a person to distinguish available and occupied chairs in the 3D office and map before attempting to claim a place.",
  "user_problem": "People need to know which nearby seats are available and who occupies the others before acting.",
  "expected_value": "Prevents unnecessary claim attempts and aligns 3D and map occupancy information.",
  "scope": "Includes nearby-chair availability, occupant identity, map parity, and live claim/release/reset updates.",
  "exclusions": [
    "Advance booking, recurring reservations, administrator override, and historical occupancy reporting are excluded."
  ],
  "acceptance_outcomes": [
    "Nearby chairs expose their current availability.",
    "Occupied chairs show the occupant's identity in the 3D scene.",
    "The floor map uses the same occupancy state and can reveal occupant names.",
    "Live claim/release/reset changes update both views without a reload."
