I’ve just been introduced to High-Fidelity JSON and I’m wondering if X3D
JSON needs it for security purposes?

*“High-Fidelity JSON (HF-JSON):*Standard JSON truncates large numbers.
Merg-E enforces HF-JSON, which embeds strict type info and CRC checksums
directly into JSON strings (e.g., "HF:int{16}1966:f37b") to guarantee data
integrity across the web.”
