Tracer Bullet: Project Chat Multi-Session UX (Create + Switch Sessions) #48
Description
Goal
Validate multi-conversation UX within a single project chat surface before persistence work lands.
Minimal Scope
- Add a sessions sidebar/panel on
/app/projects/:projectId/chat. - Implement create-new-session interaction (in-memory is acceptable for tracer bullet).
- Implement session switching interaction and active-session state.
- Ensure selected session drives which stream/messages are shown.
- Keep to happy path; no deep persistence/error recovery yet.
Acceptance Criteria
- User can create a new chat session in the project chat UI.
- User can switch between sessions in the sidebar/panel.
- Active session selection controls displayed streamed output.
- Document UX/state learnings for persistence phase.
