## ADDED Requirements

### Requirement: P3D-032 native desktop workspace
The app SHALL expose Favorites, Desktops, Pools, and Settings in a native split workspace without Apps, Add PC, manual endpoint, or direct-provider surfaces. Desktop cards SHALL use a bounded adaptive `300...360 pt` width, `16:10` aspect ratio, and `16 pt` spacing; grow continuously within natural column bands including three columns; add a column only when every card remains at least the minimum; clamp at the maximum with residual row width; and use full-bleed previews with subtle readable metadata treatment. Screenshot pixels SHALL be non-authoritative.

#### Scenario: Narrow and wide resize
- **WHEN** the workspace moves between narrow, medium, and wide widths
- **THEN** card width stays within `300...360 pt`, height preserves `16:10`, cards resize continuously within a column band, natural column transitions include three columns, and text/actions do not overflow

#### Scenario: Accessible card actions
- **WHEN** a card receives hover or keyboard focus
- **THEN** Favorite and settings controls become available without adding a connect button; double-click or Return connects

### Requirement: P3D-037 private favorites and previews
Favorites, search, sort, filters, diagnostics, and previews SHALL reveal only current authorized resources. A stable desktop MAY retain one `656 x 410` mode-`0600` preview only after an active session ends cleanly; pool art is generic and preview bytes are excluded from backup/telemetry/log/crash/support data.

#### Scenario: Failed launch and clean end
- **WHEN** a launch fails and a later active session ends cleanly
- **THEN** the failed launch preserves the old preview and only the clean end atomically replaces it

#### Scenario: Entitlement loss
- **WHEN** logout or reconciliation removes a desktop entitlement
- **THEN** its preview is cleared and cannot appear through Favorites, search, cache, or diagnostics
