# Session View

> Read the live and completed session view, panel by panel

Selecting a session loads it in the center **Content** region, with the **Details** sidebar on the right. The view adapts to whether the session is streaming live or already complete.

## Content

A breadcrumb at the top links to the session's **Project** and **Sample**. The left (Sessions) and right (Details) sidebars are collapsible, so you can widen the content area while you watch a run.

### Session controls

<Tabs>
  <Tab title="Active stream">
    While a growth is streaming, you control the session with **Pause**, **Resume**, and **End**, and
    an elapsed-time timer shows how long it has been running. A status indicator reflects the stream
    state (for example, active, paused, or interrupted).
  </Tab>

  <Tab title="Completed session">
    For a completed session, a playback bar replays the growth. Use play/pause, switch the speed
    between **1x**, **8x**, and **16x**, and drag the scrubber to jump to any point in the run.
  </Tab>
</Tabs>

### Panels

The content area shows three kinds of panels for the selected session:

* **RHEED Video**: one panel per azimuth, with its own settings menu. Each panel plays the live stream while the growth is running, or the recorded video for a completed session.
* **Growth Metrics**: charts of derived RHEED metrics with a chart settings menu. While streaming, a latency indicator shows how current the live data is.
* **Tool State**: charts of instrument parameters during the growth. A layout toggle switches the charts between horizontal and vertical arrangements.

<Note>
  The live session view shows **RHEED Video**, **Growth Metrics**, and **Tool State**. When a panel
  has no data you'll see an empty state instead:

  * **No RHEED video found for this wafer.** Stream a new growth or attach a RHEED data item to the
    physical sample to populate the view.
  * **All RHEED data is hidden.** Re-enable RHEED items from the **Resources** tab to show them.
  * **No tool state data available.** Add or stream tool state data to the physical sample to view
    it.
</Note>

## Details

The Details sidebar groups information about the selected session into three tabs.

<Tabs>
  <Tab title="Activity">
    A timeline of detected events and changepoints during the growth. Filter the timeline by label,
    magnitude, and assigner. You can relabel an event and add notes to it.
  </Tab>

  <Tab title="Metadata">
    Editable notes for the growth, plus wafer details (name, start time, target material, growth
    instrument) and the campaign it belongs to.
  </Tab>

  <Tab title="Resources">
    The data items attached to the session's physical sample, grouped by type: RHEED, Tool State, and
    any other data groups. Toggle items on or off to control what appears in the content panels. Each
    group shows an empty state when no data of that type is attached.
