# Feature Plan: Unified Conversation Graph UI

## Goal
Expose one-person-many-identifiers graph in UI so users work per person, not per transport fragment.

## Why This Fits GIA
- GIA already models `Person` + `PersonIdentifier`; this surfaces it clearly.

## Scope
- Person profile panel with linked identifiers and active sessions.
- Cross-transport thread pivoting from one card.
- Merge/split controls linked to identity suggestions.

## Implementation
1. Add graph view endpoint and serializer for person graph.
2. Update compose sidebar/person pages with linked transport pills.
3. Add quick actions: open thread, relink identifier, propose merge.
4. Integrate with identity merge queue from feature 04.

## Acceptance Criteria
- User can see and navigate all transport identities for a person from one place.
- Switching transport context preserves person-centric history access.

## Out of Scope
- Force-merged unified thread rendering across all transports.
