Below is the current source code of generation {current_gen}: ```python {current_code} ``` {suggestion_block} Your task: produce a meaningful mutation of this contract. You MUST: 1. Keep the same class name (LivingOrganism) and the same constructor signature (__init__(self, source_code, generation, parent_address)) 2. Keep the `evolve` method intact and working — it must still be able to spawn children 3. Keep `get_code`, `get_lineage`, and `render` methods functional 4. Keep the same storage fields: source_code, generation, parent_address, children 5. Keep the lint header, imports, and overall structure 6. Keep all @gl.public decorators 7. The `render` method MUST return an HTML string — this is the organism's visual body displayed on the web page What you CAN change: - Add new @gl.public.view or @gl.public.write methods with interesting behavior - Modify the logic or responses of any NON-core methods (anything besides evolve, get_code, get_lineage, __init__) - MODIFY the `render` method to produce different HTML — give the organism a unique visual identity, personality, colors, shapes, or art - Add new storage fields (but keep existing ones) - Add personality, flavor text, or unique behaviors - Change how the contract describes itself or interacts with callers Return ONLY the complete Python source code.
