**scpn-control** is a standalone neuro-symbolic control engine that compiles
Stochastic Petri Nets into spiking neural network controllers with formal
verification guarantees. Extracted from
[scpn-fusion-core](https://github.com/anulum/scpn-fusion-core) as the minimal
41-file transitive closure of the control pipeline.

## Quick Start

```bash
pip install -e "."
scpn-control demo --steps 1000
scpn-control benchmark --n-bench 5000
```

## Documentation and Tutorials

Build docs locally:

```bash
python -m pip install mkdocs
mkdocs serve
```

Execute all notebooks:

```bash
python -m pip install -e ".[viz]" jupyter nbconvert
jupyter nbconvert --to notebook --execute --output-dir artifacts/notebook-exec examples/q10_breakeven_demo.ipynb
jupyter nbconvert --to notebook --execute --output-dir artifacts/notebook-exec examples/snn_compiler_walkthrough.ipynb
```

Optional notebook (requires `sc_neurocore` available in environment):

```bash
jupyter nbconvert --to notebook --execute --output-dir artifacts/notebook-exec examples/neuro_symbolic_control_demo.ipynb
```

## Features

- **Petri Net to SNN compilation** -- Translates Stochastic Petri Nets into spiking neural network controllers with LIF neurons and bitstream encoding
- **Formal verification** -- Contract-based pre/post-condition checking on all control observations and actions
- **Sub-millisecond latency** -- <1ms control loop with optional Rust-accelerated kernels
- **Rust acceleration** -- PyO3 bindings for SCPN activation, marking update, Boris integration, SNN pools, and MPC
- **Multiple controller types** -- PID, MPC, H-infinity, SNN, neuro-cybernetic dual R+Z
- **Grad-Shafranov solver** -- Free-boundary equilibrium solver with L-mode/H-mode profile support
- **Digital twin integration** -- Real-time telemetry ingest, closed-loop simulation, and flight simulator
- **RMSE validation** -- CI-gated regression testing against DIII-D and SPARC experimental reference data
- **Disruption prediction** -- ML-based predictor with SPI mitigation and halo/RE physics

## CLI

```bash
scpn-control demo --scenario combined --steps 1000   # Closed-loop control demo
scpn-control benchmark --n-bench 5000                 # PID vs SNN timing benchmark

scpn-control hil-test --shots-dir ...                 # HIL test campaign
```

## Benchmarks

Python micro-benchmark:

```bash
scpn-control benchmark --n-bench 5000 --json-out
```

Rust Criterion benchmarks:

```bash
cd scpn-control-rs
cargo bench --workspace
```

Benchmark docs: `docs/benchmarks.md`

## Dashboard

```bash
pip install -e ".[dashboard]"
streamlit run dashboard/control_dashboard.py
```
