**GRA-StructMeta** is a demonstration laboratory for **metaprogramming of structures** — frames, ontologies, classes of laws — using the GRA (Goal–Reality–Agent) reset mechanism ("obnulënka"). It shows how classical programming gives way to a higher-level paradigm where **structures compete, mutate, and are reset** based on their alignment with data or goals.

> "Classical programming is dying. Metaprogramming of structures — the next level."

## 🧠 Core Idea

In GRA, every model or theory is represented as a **GRAFrame** – an abstract container that defines:
- How to **instantiate** a concrete model from parameters,
- How to **score** that model against reality (data, consistency, etc.).

A **GRAResetController** manages a population of frames, applying a **reset policy** that kills underperforming frames and replaces them with mutations of successful ones. This is GRA-obnulënka: a continuous cycle of **selection and regeneration** of structural hypotheses.

## 🧰 Repository Structure

- `src/core/` – The minimal GRA engine: frames, reset controller, agents.
- `src/domains/` – Domain‑specific frames for micro‑physics, biology, cosmology.
- `experiments/` – Jupyter notebooks demonstrating GRA in action.
- `examples/` – Simple Python scripts to get started.
- `docs/` – Detailed concept explanations and use cases.

## 🚀 Quick Start

```bash
git clone https://github.com/yourname/GRA-StructMeta.git
cd GRA-StructMeta
pip install -e .
python examples/minimal_frame_demo.py

🔬 Experiments

1. Micro‑law search (exp_micro_law_search.ipynb): GRA frames compete to discover Newton’s second law from synthetic data.
2. Life threshold (exp_bio_life_threshold.ipynb): Frames for non‑life, proto‑life, and life are reset as a system crosses into autopoiesis.
3. Cosmology with real data (exp_cosmo_from_cmb_bao_sn.ipynb): Frames for ΛCDM, w₀wₐ, and modified gravity are compared against CMB/BAO/SNe observations. This demonstrates GRA as an automatic meta‑theory explorer.
