+
+Combine two text inputs into a single output string using a Blacknode node graph.
+
+## Steps
+
+1. Instantiate a Text node with parameter value set to text_a
+2. Instantiate a Text node with parameter value set to text_b
+3. Instantiate a Concat node with no parameters
+4. Instantiate an Output node
+5. Connect output port 'value' of first Text node to input port 'a' of Concat node
+6. Connect output port 'value' of second Text node to input port 'b' of Concat node
+7. Connect output port 'value' of Concat node to input port 'value' of Output node
+8. Execute graph by cooking the Output node's 'value' port to obtain result
+
+## Inputs
+
+- text_a (string)
+- text_b (string)
+
+## Outputs
+
+- concatenated_text (string)
+
+## Failure Modes
+
+- One or both text inputs missing or non-string
+- Invalid node connections (port mismatch)
+- Runtime error during graph execution
