# Manage one daily seat reservation

| Feature | Parent Epic | Delivery status | Status source | Owner | Approved for Solution |

## Description

Enable a person to claim an available nearby seat, move the reservation to another seat, release it, and trust that another user's reservation cannot be displaced.

## User or operator problem

A person needs to claim, move, or release one seat without displacing another user’s reservation.

## Expected value

Provides one authoritative daily reservation outcome with visible success or failure.

## Scope

Includes contextual claim/release actions, one-seat enforcement, atomic reservation moves, ownership protection, broadcast updates, and user feedback.

### Exclusions

- Advance booking, recurring reservations, administrator override, and historical occupancy reporting are excluded.

## Acceptance outcomes

- [ ] A contextual action offers claim or release according to proximity, occupancy, and ownership.
- [ ] A user can hold at most one seat; claiming another moves the reservation atomically.
- [ ] Another user's occupied seat cannot be claimed or released.
- [ ] Claim, change, and release outcomes are visible to all affected participants.
- [ ] Success and failure are communicated to the initiating user.

## Dependencies

- [3DARCH-FT-9 — Enterprise sign-in and session continuity](../../3darch-ep-2/features/3darch-ft-9.md)
- [3DARCH-FT-23 — Discover seat availability and occupant identity](./3darch-ft-23.md)

## Risks

- Concurrent claims and reconnects require authoritative ownership checks to prevent inconsistent occupancy.
