+# 0049 — Observation overlays, offline source catalog and section navigation
+
+## Decision
+
+All apparatus observation panels place titles/actions over their viewport, without a separate header strip. A ResizeObserver reserves the real header height for status and telemetry content. DG SplitPane owns the invisible separator variant: pointer hit area, keyboard resize and keyboard focus remain available. Ratios still use the existing per-vehicle JSON layout.
+
+The apparatus detail and board monitor return through a shared circular header action. Explicit left-menu navigation remounts the workspace entry view, including repeated selection; persisted configuration and window arrangements are retained. Scene tool windows and recorded-session overview close. System contour selection returns to its default modules view. Leaving rover control invokes its existing cleanup/stop.
+
+## Sources and authority
+
+A known D455 with an empty offline capability list remains available as a camera viewport with its supported layer choices. A published nonempty capability list takes precedence. Detailed camera settings reuse SensorDetail; its capabilities and preview are not requested from an offline board.
+
+Plugins may declare a view catalog independent of physical inventory. K1 declares point cloud (3D), point cloud (top), and camera. These optional windows are listed even before enrollment, start hidden, and display an explicit disconnected-source message when selected. They never fabricate a Sensor, session, device identifier or command authority. The catalog choice is persisted in bounded catalogVisible layout data. Actual devices retain distinct device-ID-based views and replace unbound catalog entries; no ambiguous model-to-instance assignment is inferred. K1 acquisition remains an explicit operator action in its existing configurator.
+
+Source gear actions open the existing device settings in a draggable window. The layers dialog continues to control visibility and order.
+
+## Validation scope
+
+Build and offline UI acceptance cover section reset/back navigation, overlay headers, invisible pointer/keyboard resizing, layer visibility/persistence, disconnected notices and settings access. Unit cases cover D455 capability precedence, ambiguous plugin rejection, template/physical-device separation and bounded catalog persistence. The board was offline during this change: live RealSense/XGRIDS delivery and hardware settings are not claimed as accepted.
