+## 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.
+
+## 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-24/tasks.md). No canonical implementation Tasks have been defined.
