+#### **Error Handling**
+
+This library includes basic error handling to ensure workflows continue running smoothly, even when unexpected issues arise.
+
+#### **Navigation Errors**
+
+If a prompt doesn't match a valid adjacent region, the system will:
+- Log a warning: `No valid region found for prompt: "<prompt>"`
+- Continue without changing the current region.
+
+#### **Operator Execution Errors**
+
+If no matching operator is found for a prompt, or an operator encounters an error during execution:
+- Log a warning: `No matching operator found for intent: <intent>`
+- Log an error if execution fails: `Error during workflow execution for prompt "<prompt>": <error message>`
+
+#### **LLM Query Errors**
+
+In case of issues querying the LLM service:
+- Log an error: `Error during navigation for prompt "<prompt>": <error message>`
+
+#### **Example Error Logging**
+
+```javascript
+const manifold = new WorkflowFunctionManifold(new DummyLlmService());
+
+try {
+    await manifold.navigate('unknown command');
+} catch (error) {
+    console.error('Critical navigation error:', error);
+}
+
+try {
+    await manifold.executeWorkflow('perform unknown action');
+} catch (error) {
+    console.error('Critical execution error:', error);
+}
+```
