## ADDED Requirements

### Requirement: New sessions appear in lists immediately
The system SHALL add a newly created session to every session list as soon as the creation API returns.

#### Scenario: Create session from floating button
- **WHEN** the user starts a tool from the global floating action button
- **THEN** the modal closes
- **AND** the new session appears on the dashboard and sessions page with status "pending" or "building"
- **AND** the active session count in the navigation updates immediately

#### Scenario: Create session from repository detail
- **WHEN** the user launches a tool inside a repository/workspace detail page
- **THEN** the new session appears in the repository instance list
- **AND** the global session lists update without requiring a manual refresh

### Requirement: Global session state is authoritative
The system SHALL use a single shared session state for the navigation sidebar, dashboard, and sessions page.

#### Scenario: Shared state updated
- **WHEN** a session is added, removed, or changed
- **THEN** the navigation badge, dashboard, and sessions page all reflect the change
- **AND** no page reload is required
