GVF: Generator–Validator–Fixer (visual scripting)

Quick start

python -m venv .venv && source .venv/bin/activate
pip install -r requirements.txt
export OPENAI_API_KEY=...         # or GOOGLE_API_KEY=...
python cli.py --provider openai --model gpt-4o-mini --use_llm_fixer

What it does

• Generates a GUIDE + BLOCKS artifact from a natural-language prompt.
• Validates in fixed order (C1–C6).
• Applies local heuristic patches; escalates to LLM for ambiguous choices.
• Re-validates the same category before advancing.
