# Recognize coworkers by workplace identity

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

## Description

Enable a participant to recognize each current-floor coworker by persisted avatar and visible name in both the 3D scene and map.

## User or operator problem

Participants need to recognize each coworker consistently across the 3D scene and floor map.

## Expected value

Provides stable social recognition across scene and map representations.

## Scope

Includes persisted avatar selection, safe avatar fallback, visible names, map labels, and identity-change reconciliation.

### Exclusions

- Communication content and seat-reservation ownership are excluded.

## Acceptance outcomes

- [ ] Every current-floor participant renders as one embodied avatar.
- [ ] The persisted avatar is used when valid, with a safe fallback for an unavailable model.
- [ ] A visible name label follows each remote avatar.
- [ ] The floor map shows labeled coworker markers and distinguishes the local participant.
- [ ] Identity changes propagate without creating a duplicate participant.

## Dependencies

- [3DARCH-FT-10 — First-entry avatar onboarding](../../3darch-ep-2/features/3darch-ft-10.md)
- [3DARCH-FT-18 — See who shares the current floor](./3darch-ft-18.md)

## Risks

- Missing avatar models and delayed profile changes can reduce reliable coworker recognition.

## 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.

## 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.
