# SYF‑Minimal

Minimal, non‑canonical reference implementation of the Systemic Fire (SYF) invariant.

## Related Repositories

- **SYF‑Lab — Experimental and observational framework**  
  https://github.com/AnathemaOfficial/SYF-Lab

## Status

- Non‑canonical  
- Non‑normative  
- Reference / verification only  
- Not a machine learning model  
- Not intended for deployment or inference  

This repository does **not** define, modify, or extend the SYF law.  
Any discrepancy with SYF‑Core must be treated as an implementation error.

## Purpose

- Demonstrate deterministic computation of the invariant  
- Provide minimal reference code and test vectors  
- Enable blind analysis and external verification  

## Law

\[
R = \frac{F \times E}{K}
\]

### Constraints enforced by the reference implementations

- \(F \ge 0\)  
- \(0 \le E \le 1\)  
- \(K > 0\)  

Inputs outside this domain must be rejected (error/exception).  
No clamping.  
Numerical tolerance, if any, is implementation‑defined.
