+
+## Description
+
+Enable a person to distinguish available and occupied chairs in the 3D office and map before attempting to claim a place.
+
+## User or operator 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.
+
+## Dependencies
+
+- [3DARCH-FT-17 — Orient with the live floor map](../../3darch-ep-3/features/3darch-ft-17.md)
+- [3DARCH-FT-19 — Recognize coworkers by workplace identity](../../3darch-ep-4/features/3darch-ft-19.md)
+
+## Risks
+
+- The legacy client bulk-reset listener does not correctly consume the server reset payload.
+
+## Human approval
+
+Linas approved this Feature for documentation on 2026-09-02T10:40:43.220Z. It is **not Approved for Solution** and has no implementation approval.
+
+- [Documentation decision](https://discord.com/channels/1518726359512387766/1543925247361814568/1544658325738885201)
+
+## Delivery status evidence
+
+The Feature was separately registered at `IN_BACKLOG` as an accepted catalogue boundary. This records backlog retention, not design or delivery progress.
+
+- Event: Catalogue registration
+- Actor and authority: Linas — Human project team member
+- Reason: The Feature catalogue was accepted for governed documentation and retained in the backlog.
+- [Status evidence](https://discord.com/channels/1518726359512387766/1543925247361814568/1544658325738885201)
+
+## Architecture traceability
+
+- Requirements: none derived.
+- Readiness: Not started.
+
+Architecture solution work must not begin until a separate human **Approved for Solution** decision is recorded.
+
+## Tasks
+
+[Review the Tasks group](./3darch-ft-23/tasks.md). No canonical implementation Tasks have been defined.
