steps:
- Create a Blacknode Graph instance
- Add a Text node with param value set to text_a
- Add a second Text node with param value set to text_b
- Add a Concat node that accepts inputs 'a' and 'b' and outputs 'value'
- Add an Output node with input port 'value'
- Connect first Text node 'value' port to Concat 'a' port
- Connect second Text node 'value' port to Concat 'b' port
- Connect Concat 'value' port to Output 'value' port
- Invoke graph cook on Output 'value' to evaluate and return result

# text-concatenation

Concatenate two text inputs using Blacknode node graph

## Steps

1. Create a Blacknode Graph instance
2. Add a Text node with param value set to text_a
3. Add a second Text node with param value set to text_b
4. Add a Concat node that accepts inputs 'a' and 'b' and outputs 'value'
5. Add an Output node with input port 'value'
6. Connect first Text node 'value' port to Concat 'a' port
7. Connect second Text node 'value' port to Concat 'b' port
8. Connect Concat 'value' port to Output 'value' port
9. Invoke graph cook on Output 'value' to evaluate and return result

## Inputs

- text_a
- text_b

## Outputs

- concatenated_text

## Failure Modes

- Port name mismatch causes connection error
- Missing runtime or graph not initialized
- Cook on nonexistent node returns error
