| Evolution & Grafting |
Improve top hypotheses through evolution and hypothesis merging |
✅ Implemented in EvolutionAgent with grafting logic |
| Meta-Review / Summary |
Generate a unified research direction based on evolved hypotheses |
✅ Done with MetaReviewAgent and DSPy |

View ELO evolution and trace decisions |
✅ Done with view_ranking_trace.py |
🚀 What We’ve Extended Beyond the Paper
| Feature |
Description |
| DSPy Integration |
Modularized all logic into composable DSPy Signatures and Modules |
| Grafting |
Introduced “hypothesis grafting” as an optional step to merge similar ideas |
| Full Pipeline CLI |
YAML-configurable end-to-end execution (run_pipeline.py) |
| ELO Visualization |
Added CLI-based ranking visualization (top scores + ELO evolution) |
| Local-first Design |
Works 100% locally using Ollama, Postgres, and pgvector |
| Extensible Memory Interface |
Abstracted memory layer to allow swaps (e.g., Haystack, Weaviate) |
| Meta Reasoning Hooks |
Ready for Teleprompter optimization, critic loops, and reward models |
🔬 Further Research / Expansion Areas
| Area |
Opportunity |
| 🧠 Teleprompter Optimization |
