syntax only not reachability or ownership verification

The contract

Validation is not verification.

01

Deterministic

The same input, options and pinned reference dataset produce the same result.

02

Versioned

Every response names its rule version and carries a stable machine-readable reason code.

03

Bounded

A valid shape never proves identity, ownership, reachability, authenticity or real-world existence.
