• K is provided by the caller; the canonical law does not define its value.
• Inputs outside the allowed domain (F ≥ 0, 0 ≤ E ≤ 1, K > 0) MUST be rejected (error/exception). No clamping.
• Numerical tolerance, if any, is implementation-defined and must be documented by the implementation.
• This repository is illustrative and non-production by design.

SYF-Minimal is a non-canonical, non-normative reference implementation designed to illustrate and test the invariant R defined in SYFCORE.

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

• Demonstrate deterministic computation of R
• Provide test vectors and minimal reference code
• Support external verification and blind testing

R = (F × E) / K

Constraints enforced by the reference implementations:

• F ≥ 0
• 0 ≤ E ≤ 1
• K > 0
