# Home Tab

The Home tab is your command center for a Digital Twin. It provides an at-a-glance overview of your model's status and quick access to the most common actions.

When you first open a Digital Twin, you land here. It's designed to answer the immediate questions: What version am I looking at? Is the model ready to use? What can I do next?

### Twin Overview

At the top of the Home tab, you'll see key information about your Digital Twin:

**Name and Type**

The twin's name appears prominently, along with a badge indicating whether it's a **Static Model** or **Time Series Model**. Static twins analyze cross-sectional data; temporal twins capture time-based dynamics.

**Tags**

Tags help organize twins across your workspace. Click **Edit** to add or modify tags—useful for categorizing by project, team, or analysis type.

**Created Date**

Shows when this Digital Twin was first created.

### Active Version

Digital Twins support multiple versions, and this section shows which one you're currently viewing.

**Version Selector**

Click the version dropdown to switch between versions. Each version represents a different causal discovery run—perhaps with different data, different included fields, or different constraints.

**Version Details**

For the active version, you'll see:

| Metric        | Description                               |
| ------------- | ----------------------------------------- |
| Version       | The version number (e.g., v1.0.0)         |
| Variables     | Number of variables included in the model |
| Relationships | Number of causal relationships discovered |
| Status        | Current state of the model                |

**Status Values:**

* **Ready for analysis** – The model is fully trained and can run simulations
* **Directions unresolved** – Some relationships have ambiguous direction (CPDAG state) and need resolution
* **Model not trained** – The causal graph exists but the probabilistic model hasn't been fit yet
* **Graph not constructed** – Causal discovery hasn't been run yet

**View All Versions**

Click "View All Versions" to see a visual diagram of your version history, showing how versions branch and relate to each other.

### Quick Actions

The quick actions panel provides one-click access to common tasks. Available actions depend on your model's current status.

**Always Available:**

| Action                     | Description                                                                         |
| -------------------------- | ----------------------------------------------------------------------------------- |
| **Configure Digital Twin** | Go to the Config tab to modify settings, add constraints, or change included fields |
| **View Relationships**     | Open the Relationships tab to explore the causal graph                              |

**Available When Model Is Trained:**

| Action                    | Description                                 |
| ------------------------- | ------------------------------------------- |
| **Run Prediction**        | Predict outcomes for specific inputs        |
| **Optimize Variables**    | Find optimal settings to achieve objectives |
| **Test Interventions**    | Simulate what-if scenarios                  |
| **Generate Best Actions** | Find minimum changes to reach a target      |
| **Model Evaluation**      | View accuracy and performance metrics       |
| **View All Runs**         | See history of all simulation runs          |

### When Actions Are Disabled

If some actions are grayed out, the model needs attention:

**Edge Resolution Required**

If the causal graph contains bidirectional relationships (the algorithm couldn't determine direction), you'll see a prompt to resolve them. Click "Resolve Relationships" to go to the Relationships tab and manually specify directions.

**Model Training Required**

If the graph is complete but the model hasn't been trained, you'll need to train it before running simulations. This typically happens automatically after edge resolution.

### Editing Twin Details

Click **Edit** in the header to modify:

* **Name** – Rename the Digital Twin
* **Tags** – Add, remove, or modify tags

Changes are saved when you click **Save**. Click **Cancel** to discard changes.

### Next Steps

From the Home tab, you'll typically:

* Review the version status to understand if the model is ready
* Use quick actions to jump directly to analysis
* Navigate to the [Config Tab](https://docs.rootcause.ai/user-guide/digital-twin/tabs/config-tab) if you need to modify settings
* Go to [Relationships Tab](https://docs.rootcause.ai/user-guide/digital-twin/tabs/relationships-tab) if edges need resolution
