# Coordinate Shared Workplace Seating

| Epic | Delivery status | Status source | Owner | Approved for Solution |
|---|---|---|---|---|
| `3DARCH-EP-6` | `IN_BACKLOG` | `DERIVED` | 3D Architecture Wizzard team | No |

## Goal

Expose seat availability and occupant identity in the office and map, and support conflict-safe claim, change, release, and daily reset behavior.

## Benefit

Shared seating becomes self-service and trustworthy while each person holds at most one seat.

## Problem or opportunity

People need to discover and claim shared seating without collisions, hidden occupancy, or the ability to displace another occupant.

## Constraints

- Only materially implemented legacy behavior is included; planned-only capabilities remain outside the approved catalogue.

## Features

- [3DARCH-FT-23 — Discover seat availability and occupant identity](./3darch-ep-6/features/3darch-ft-23.md)
- [3DARCH-FT-24 — Manage one daily seat reservation](./3darch-ep-6/features/3darch-ft-24.md)
- [3DARCH-FT-25 — Expire stale seat claims at the workplace-day boundary](./3darch-ep-6/features/3darch-ft-25.md)

These Features are approved for documentation only. Each remains outside Architecture solution work until a separate human **Approved for Solution** decision is recorded.
