# EGPv3

EGPv3 is a debate-then-judge extension of EGP for SafeHome anomaly analysis.

- It does **not** expose `SQ1-SQ5` labels to the model.
- It replaces the serial veto chain with:
  - a neutral `Extractor`
  - a recall-oriented `Prosecutor`
  - a precision-oriented `Defender`
  - a final `Judge`
- The Judge sees the same raw focused evidence as both sides, reducing information decay.

## Files

- `api_client.py`: OpenAI-compatible API client, optional API key, supports `--thinking` / `--no-thinking`
- `benchmark.py`: episode collection and resume helpers
- `signals.py`: deterministic chunking and structured signal extraction
- `prompts.py`: extractor / prosecutor / defender / judge prompts
- `pipeline.py`: debate orchestration
- `run_egpv3.py`: CLI runner

## Quick test

```bash
python EGPv3/run_egpv3.py --preview-only --max-episodes 1 --output-dir results/egpv3_preview
```

`preview-only` only materializes prompts and traces. It does not call a model, so `UNPARSEABLE` in the preview summary is expected.
